version 0.1 - August 2013

[1]Warning: at the moment this code is just a *proof-of-concept*

I. INSTALL LAZARUS PACKAGE (laz4android1.1-41139)

   1. From lazarus IDE

      1.1 Package -> Open Package -> "lazandroidwizardpack.lpk"
  
      1.2 From Package Wizard
          1.2.1 Compile
          1.2.2 Use -> Install

II. USE

1. From Eclipse IDE

  1.1. File -> New -> Android Application Project

  1.2. From Package Explore -> src
   
       Right click your recent created package -> new -> class 
   
       Enter new class name... (ex. JNIHello)
  
       Edit class code for wrapper native methods (ex...)

Code: [Select]
                package org.jmpessoa.app1;
 
        public class JNIHello {

           public native String getString(int flag);
           public native int getSum(int x, int y);

                   static {
                try {
                    System.loadLibrary("jnihello");               
                } catch(UnsatisfiedLinkError ule) {
                    ule.printStackTrace();
                }
                   }
             } 


  1.3. warning: System.loadLibrary("...") must match class Name lower

Hi There,

I made some improvements on parse (and bug fix  ).

Now Java method signature like this:

Code: [Select]public native int getGraphics(ByteBuffer graphicsBuffer,
int w, int h);   

Is handled correctly:

Code: [Select]{ Class:     org_jmpessoa_pascalgraphics_GraphicsBoard
  Method:    getGraphics
  Signature: (Ljava/nio/ByteBuffer;II)I }

function getGraphics(PEnv: PJNIEnv; this: JObject; graphicsBuffer:
JObject; w: JInt; h: JInt): JInt; cdecl;
begin

end;

Code: [Select]const NativeMethods:array[0..0] of JNINativeMethod = (
   (name:'getGraphics';
    signature:'(Ljava/nio/ByteBuffer;II)I';
    fnPtr:@getGraphics;)
);

Follows some example picture..... and the package (*.rar)

Greetings!

Thank you for sharing your code.    It did help me learn a few things
like Lazarus project wizards and  Android ARM v7 needed compiler
options.

I had only one simple problem using it due to hard-coded path
"C:\adt32\eclipse\workspace" in:

uformandroidproject.pas (FormAndroidProject) --> ShellTreeView1 -->
Root

it worked after creating these folders and allowed my to change it to
my actual folder 

While working on your wizard did you have to re-build Lazarus every
time you made a small change? or am I missing something? 

Is it possible to use Build Modes to add compiler settings for both
Arm v6 and v7 and maybe i386 to the same project using your project
wizard?

Thanks again.

----------------------------------------------------------------------
jmpessoa · 2013-10-10 15:09

Hi engkin, thank you!

Actually when you modify a package you need re-install (this is
a Lazarus question)...

Hint: for install and re-intall package in Lazarus4Android close any
cross-compile-android project and open a window project!

Please get  more updated version from:

https://github.com/jmpessoa/lazandroidmodulewizard

I will fix the hard path today!

Sorry, I have not learned about Build Modes...

Greetings!

With the risk of being shot as the messenger...this development is the
the lifeboat for Lazarus.
Android is a significant market and is growing. Future apps will be on
handheld devices. Lazarus needs a robust path to Android. Many have
given up already on Lazarus sure they could spend weeks trying to get
Lazarus  to compile a single app but it is smarter to go another
route. The originator of this smart approach admits the reason for
this direction is that they realized the futility of the existing
approach. This effort is trying to bring smart back and bury the
obtuse solutions offered to date. Smart work!

Hi All,

At the moment I am working hard to bring

Android Controls for Lazarus  by simonsayz

(http://forum.lazarus.freepascal.org/index.php/topic,22079.0.html)

to talk with my Android Module Wizard.... follows some figures.

Thanks to all!

Hi All,

I can already anticipate some information about what we're talking
about: very little code, just design ( without form design) ... that
is: component model, LazAndroidWizard and  Object Inspector does the
task....

The first part of my task is almost ready .... I hope to make
available my code very soon!

Follow some results just for curiosity ...

happy Sunday day!

So it will look like a data module, no visual design? The layout must
be done through code then, right? No problem actually, it's already a
big step. The visual designer could wait

----------------------------------------------------------------------
jmpessoa · 2013-11-17 15:24

@Leledumbo:  QuoteThe layout must be done through code then, right?
Yes, too. But basically I am using just the Object Inspector to
configure the layout, in this sense no coding!

Thank you!

----------------------------------------------------------------------

patiently.

jmpessoa · 2013-11-17 19:36

Hi engkin,

Thanks for your interest .... I will need help for the next step:
build the entire cycle of application without Eclipse!

Greetings!

----------------------------------------------------------------------
engkin · 2013-11-17 19:53

I'm willing to help, assuming that I'm able to.

----------------------------------------------------------------------
Leledumbo · 2013-11-18 15:47

QuoteYes, too. But basically I am using just the Object Inspector to

relative positioning or absolute or something else?

----------------------------------------------------------------------
jmpessoa · 2013-11-18 17:01

@Leledumbo

QuoteHmm... does it use relative positioning or absolute or something
else?
Yes, relative e something else too!

In my posted *.lfm, you can see:

Code: [Select]object jEditText1: jEditText
    Id = 53166
    Anchor = jTextView2
    PosRelativeToAnchor = [raBelow]
    PosRelativeToParent = [rpLeft]
    LayoutParamWidth = lpTwoThirdOfParent
    LayoutParamHeight = lpWrapContent
    MarginLeft = 10
    MarginTop = 10
    MarginRight = 10
    MarginBottom = 10
    ...............................................
  end
  object jButton1: jButton
    Id = 0
    Anchor = jEditText1
    PosRelativeToAnchor = [raToRightOf, raAlignBaseline]
    PosRelativeToParent = []
    LayoutParamWidth = lpOneThirdOfParent
    LayoutParamHeight = lpWrapContent
    ..............................................
  end 

The main concept is "Anchor"  and the possibilities (at the moment...)
are:

Code: [Select] TPositionRelativeToAnchor = ( raAbove,
                                  raBelow,
                                  raToStartOf,
                                  raToEndOf,
                                  raToLeftOf,
                                  raToRightOf,
                                  raAlignBaseline,
                                  raAlignTop,
                                  raAlignBottom,
                                  raAlignStart,
                                  raAlignEnd,
                                  raAlignLeft,
                                  raAlignRight);

  TPositionRelativeToParent = (rpBottom,
                               rpTop,
                               rpLeft,
                               rpRight,
                               rpStart,
                               rpEnd,
                               rpCenterHorizontal,
                               rpCenterInParent,
                               rpCenterVertical
                               {rpTrue});

  TLayoutParams = (lpMatchParent, lpWrapContent, lpHalfOfParent,
lpOneQuarterOfParent,
                   lpTwoThirdOfParent ,lpOneThirdOfParent,
lpOneEighthOfParent,
                   lpOneFifthOfParent, lpTwoFifthOfParent,
lpThreeFifthOfParent, lpFourFifthOfParent,
                   lp16px, lp24px, lp32px, lp40px, lp48px, lp72px,

and from *.pas you can see:

Code: [Select]procedure TAndroidModule6.DataModuleRotate(Sender:
TObject; rotate: integer;
  var rstRotate: integer);
begin

end;

Follow the attached a image after device direction change....

Thank you!

OK, that looks good. At least no need to worry the controls will be
overlapping.

This seems great, and I guess a visual design could be added
completely bypassing the Form Designer - the way reports are created
for example. Clicking on a nonvisual component could open a small
designer for placing and drawing controls, even a primitive one would
be sufficient help for Android, I guess...

Hi All,

I got another step in the layout management, especially the device
orietation change challenge.

Yes, the *NEW* jPanel simplifies and actually makes this task very
easy and "smart".

Follows code and image just for exemplification....

Achieved that goal I inclose the first part of my work and will try to
available the new version of my LazAndroidWizard
with support for  simonsayz's  Controls (including my own extensions..

Now I will focus on writing a more complete readme.txt/tutorial.... I
want to complete this task as quickly as possible (03 days?)

Thank to All and special thanks to Simonsayz!

Leledumbo · 2013-12-14 06:45

Thank you, jmpessoa. I'm on my way to the github page
You should put the demo in the github as well IMO, better in its own
folder and let everybody adds their own

Hmm... it seems that Eclipse (workspace) is required to create any
project with this. I think it could be removed and we could provide
standard Android project structure that only requires ant to build, as
simonsayz libraries do.

----------------------------------------------------------------------
jmpessoa · 2013-12-14 15:17

@Leledumbo,

Yes, the Eclipse dependency needs to be removed!

I will try learn about  this part of the problem, I will study
@simonsayz solution and @delphifreak solution....

Yes, I put the AppDemos on github now...

Thank you very much for your interest!

----------------------------------------------------------------------
Sergionn · 2013-12-14 15:59

Also thank you, Jmpessoa for your work!!!!!!!!!
Eclipse dependency not the right way, it should be done like in
Simon's work.
By the way - maybe someones knows - what happends with Simon, why he
does't continue his work?

----------------------------------------------------------------------
Leledumbo · 2013-12-14 16:15

Hmm... I got linker errors due to either .lpk requiring NDK libraries
to link with the IDE but it's not stated anywhere in the readme.

----------------------------------------------------------------------
jmpessoa · 2013-12-14 16:45

@Leledumbo:

I put this on readme.txt:

Code: [Select]  warning: the original laz4android1.1-41139 is win32
and just for Android NDK-7c

but I do not know if I understood your question ...

@Sergionn:

Yes, Simon help is very important, I tried some communication with him
but had no success...

Thank you.

QuoteI put this on readme.txt:

Code: [Select]
  warning: the original laz4android1.1-41139 is win32 and just for

but I do not know if I understood your question ...Upon installing, I
got these:
Quote/usr/bin/ld: cannot find -lGLESv2
/usr/bin/ld: cannot find -lGLESv1_CM
/usr/bin/ld: cannot find -ljnigraphics
/usr/bin/ld: cannot find -llog
I do know they're part of NDK, it's easy to find them. But any of the
.lpk doesn't contain path to these libs (-Fl) and the readme contains
no instruction for this.

----------------------------------------------------------------------
jmpessoa · 2013-12-14 17:43

@Leledumbo,

1. You is using Windows or Linux?

2. Please check my "Android Module Wizard: Configure Paths"

    ref Image:   
 https://www.opendrive.com/files?Ml8zNjMwMTk0Nl9hNEtBUw

3. Yes, they're part of NDK,  the interfaces are:

    Laz_And_GLESv1_Canvas_h.pas
    Laz_And_GLESv2_Canvas_h.pas
    And_bitmap_h.pas
    And_log_h.pas

I'm trying to understand your question.

Thank you.

QuoteYou is using Windows or Linux? Linux
QuotePlease check my "Android Module Wizard: Configure Paths" I
haven't gone that far, the problem appears when installing the .lpk to
the IDE

----------------------------------------------------------------------
jmpessoa · 2013-12-14 18:31

@Leledumbo,

Linux?

I haven't gone that far too...    

1. At the moment "lazandroidwizardpack.lpk" has a simple Windows
dependency

the '/'  separator! I will fix this! (Edit: Directory Separator was
Fix! )

2. The  "tfpandroidbridge_pack.lpk" I don't remember, I will see.
(Edit: No problem found!)

What *.lpk  is you trying?

Thanks.

Hi,

I Add new infos in Readme.txt,

About Package, Components and LCL  and NDK libs(.so) dependency on
laz4android1.1-41139 IDE cross compiler...

1. Package creation: just LCLBase is permitted! not "LCL"!
  
   - You will nedd  LCLBase Required Package for register procedure.
   - yes, other No GUI stuff is permitted.

2. Component creation
  
    2.1. If you will use custom icon then you will need two files: the
first to compoment(s) code
        and the second for Register procedure code.

        example:

    2.1.1. File 1 - "foo.pas" - component code - here no LCL
dependency at all!

Code: [Select]  unit foo;

        {$mode objfpc}{$H+}

        interface

        uses
                Classes, SysUtils;

        type

        TFoo = class(TComponent)
        private
        { Private declarations }
        protected
        { Protected declarations }
        public
        { Public declarations }
        published
        { Published declarations }
        end;


        implementation

 
        end.
       
  2.1.2. File 2 - "regtfoo.pas" - register code -  here you will need
LCLBase for LResources unit

Code: [Select]        unit regtfoo;

        {$mode objfpc}{$H+}

        interface

        uses
                Classes, SysUtils, LResources{ here is the LCLBase
dependency!};

        Procedure Register;

        implementation

        Procedure Register;
        begin

          {$I tfoo_icon.lrs}  //you custom icon

          RegisterComponents('Android Bridges',[TFoo);

        end;

        initialization

        end.  

3. NDK libs (.so) dependency on laz4android1.1-41139 IDE cross
compiler
    

3.1.  You will need two files: the first to NDK *.so lib interface and
the second for you component/unit code.

   Example:


   3.1.1. File 1 - "And_log_h.pas" the header interface file
 Code: [Select] unit And_log_h;

         {$mode delphi}

        interface

        const libname='liblog.so';

        ANDROID_LOG_UNKNOWN=0;
        ANDROID_LOG_DEFAULT=1;
        ANDROID_LOG_VERBOSE=2;
        ANDROID_LOG_DEBUG=3;
        ANDROID_LOG_INFO=4;
        ANDROID_LOG_WARN=5;
        ANDROID_LOG_ERROR=6;
        ANDROID_LOG_FATAL=7;
        ANDROID_LOG_SILENT=8;

        type

          android_LogPriority=integer;

          function __android_log_write(prio:longint; tag,text:
pchar):longint; cdecl; external libname name '__android_log_write';

          function LOGI(prio:longint;tag,text:pchar):longint; cdecl;
varargs; external libname name '__android_log_print';


        implementation

        end.


      3.1.2. File 2 - "And_log.pas" component/unit code

Code: [Select]  unit And_log;

        interface

        uses
           And_log_h;  // <-- here is the link to NDK lib

        procedure log(msg: pchar);

        implementation

        procedure log(msg: pchar);
        begin
            __android_log_write(ANDROID_LOG_FATAL,'crap',msg);
        end;

        end.

Thank you.

QuoteLinux?

I haven't gone that far too...     I don't think this should be locked
to certain platform, if it could work on Windows, it should work on
any other supported OS.
Quote1. At the moment "lazandroidwizardpack.lpk" has a simple Windows
dependency

the '/'  separator! I will fix this! (Edit: Directory Separator was
Fix! )Simple, isn't it? The cross platform constants are in the System
unit
Quote2. The  "tfpandroidbridge_pack.lpk" I don't remember, I will see.
(Edit: No problem found!)

What *.lpk  is you trying?Both.
lazandroidmodulewizard has implicit dependencies on jnigraphics in
androidwizard_intf due to its dependency on Android_jni_bridge via
Laz_And_Controls unit. While tfpandroidbridge has dependencies on all
of those .so (GLESv2, GLESv1_CM, jnigraphics, log).

----------------------------------------------------------------------
jmpessoa · 2013-12-15 04:30

@Leledumbo

Yes,

I have this problem too on windows and laz4android1.1-41139 cross
compile... my solution was that I wrote in my post  up  

Code: [Select]About Package, Components and LCL  and NDK libs(.so)
dependency on laz4android1.1-41139 IDE cross compiler...

And with this strategies it was resolved on windows!

But I learned something else ... before installing a package I close
my cross compile project and open a "dummy" windows project....

And so things are working... but on linux it seems that the behavior
is another ...



Thank you

----------------------------------------------------------------------
Leledumbo · 2013-12-15 05:20

I'm going to check what laz4android does so that the IDE can link to
those .so

EDIT: it doesn't seem to have anything to do with laz4android, so it's
purely tfpandroidbridge problem. On Windows, shared library doesn't
have to exist upon linking. While on *nix, it's a must. I need to find
a workaround for this.

----------------------------------------------------------------------
zariq · 2013-12-15 15:54

Hi.

Copied appdemo1 onto phone, looks nice. Must have taken a lot of work,
jni is very laborious. Just a few of minor points.

I couldn't get the back key to work from the main (menu) form.  I had
to press the home key, which leaves it paused in the background or
kill it from task manager.

Pressing the return key in edittext inserts a line but also hides the
keynoard. That should only happen if it's a "done" or "go".

Just incase you forget imageview needs scaletype implementing. FIT_XY
distorts the image if the imageview is larger but wrong scale.

Thanks.

----------------------------------------------------------------------
jmpessoa · 2013-12-15 15:56

@Leledumbo,

Yes, After many experimentations, I  found a workaround for Windows
just as posted up:

QuoteAbout Package, Components and LCL  and NDK libs(.so) dependency
on laz4android1.1-41139 IDE cross compiler...

Thank you.

----------------------------------------------------------------------
jmpessoa · 2013-12-15 16:12

@zariq,

Thank you for the experimentation...

Yes, and our work is just beginning ... I am learning
yet!  surely every collaboration is welcome! JNI is hard and our task
is build a RAD environment for android too, Lazarus is about it!

About:

I will try a solution.

Hi All,

Yes, Ant support almost ready!

I got:

1. Compile/Build ---> I got the Apk!
2. Install in Emulator
3. Uninstall from Emulator

But when I run App from Emulator I got:

Something was forgotten to bind  my native "libcontrols.so" on Apk?

Thank You.

Edit: I found this:
Quote  It turns out that this was a bug in the Android SDK. The
release notes of r18 say:

  "Fixed Ant issues where some jar libraries in the libs/ folder are
not picked up in some cases."

  Since updating from r17 to r19 fixed the problem for me, this was
very likely the cause of the problem.

Ref. http://stackoverflow.com/questions/9944698/why-is-the-android-
support-library-not-added-to-my-apk

I will update my SDK r17 for r19 too, and try again!

Edit2: While I wait for my SDK update, I ran:

aapt.exe list AppAntDemo1-debug.apk, and for my surprise:

In the version I downloaded you had controls with a small c.

----------------------------------------------------------------------
jmpessoa · 2013-12-18 03:21

@Zarik,

thank you for replay.

I have a file  "Controls.java" and a class "Controls":
Code: [Select]//------------------------------------------------------
------------------------
//Javas/Pascal Interface Class
//--------------------------------------------------------------------
----------
//!!!! classcontrols 
//
public  class Controls {

public  native int  pAppOnScreenStyle();
public  native void pAppOnCreate     (Context context,RelativeLayout

Yes, there is a small "control" in System.loadLibrary("controls").....

And more, in my /bin/classes I got the compiled  "Controls.class"!

----------------------------------------------------------------------
jmpessoa · 2013-12-19 18:49

Yes,  after a complete cleanup in my Android SDK, the problem was
solved!

The support for Ant project is on the way!

Thanks to All.

----------------------------------------------------------------------
Leledumbo · 2013-12-20 06:31

I'm still struggling to make the package installable on Linux. It's
kinda weird actually since, for example, the And_Bitmap_h functions
called links to libjnigraphics.so which is part of the TARGET
(Android), the HOST (Linux) shouldn't need it. Even if it should,
which libjnigraphics.so should the IDE link to? x86? arm? Neither is
right, since the .so is not meant for the HOST.

----------------------------------------------------------------------
jmpessoa · 2013-12-22 07:12

Hi All,

Android Module Wizard Ver. 0.3 -  Introduces Support to Ant Project!

Now you can manage the entire cycle of application development just
using Lazarus  and native tools:  jdk, ant, sdk and ndk.

You can get here:

         http://wwww.github.com/jmpessoa

For a complete description, please, read the updated "readme.txt"

Attached below the new entry form for project and paths
configuration...

Thank to all!

----------------------------------------------------------------------
Sergionn · 2013-12-22 07:36

Jmpessoa, yor are good for strugging for pascal's future by doing
this. Thank you!
But give you you little advice:
1) Simplify all STEPS to do to archive the result, it should be like
this:
 a) install packadge
 b) load project
 c) build it
 - thats it, until this it will be more easy to make android apps in
andoid studio or eclipse or whatever
 and even to study java not such commplicated quest compared by
following all instructions in readme file of your project........
 and please remove eclipse projects and any dependency about it for
simpify

----------------------------------------------------------------------
jmpessoa · 2013-12-22 14:42

@Sergionn, thaks for your advice:

I will, split "readme.txt": one for Eclipse users and other for Ant
users.... I hope  so things will be less complicated... the fact is
that there is still a java background in development (Simon's
"Control.java" + "App.java") and so support the eclipse help much ...

Thank you!

----------------------------------------------------------------------
jmpessoa · 2013-12-22 18:55

Also can you share your investigations in using freetype2 lib on
android?
http://forum.lazarus.freepascal.org/index.php?topic=21923.0

----------------------------------------------------------------------
Leledumbo · 2013-12-29 16:21

I've managed to make the package linked on linux, using some dirty
hacks:
Build all libraries in the attachmentPut it somewhere ldconfig can
find (or just run ldconfig with their directories as arguments)Do a
little modification in Laz_And_GLESv1_Canvas_h and
Laz_And_GLESv2_Canvas_h by using ifdef for desktop platforms (details
below)Required changes:
Code: [Select]// in Laz_And_GLESv1_Canvas_h
libname = {$ifdef android}'libGLESv1_CM.so'{$else}'libGL.so'{$endif};
// in Laz_And_GLESv2_Canvas_h
libname = {$ifdef android}'libGLESv2.so'{$else}'libGL.so'{$endif};
The only missing OpenGL function is glFustrumf, which I add in the
dummy libjnigraphics. The idea of this is just to make the package
installable in the IDE, applications will still use the android
version of the libraries.

UPDATE: Ant demo project works beautifully on my MI2S
Just a suggestion: no need to rar any of the demo projects, let them
as is for easy update. Compressing will only make update tracking
difficult.

UPDATE #2: Eclipse demo projects easily converted to Ant project, just
need to copy build.xml in the AppAntDemo1. I found some bugs with
these demos, such as not being able to exit app by pressing back, but
that's just a little bug which I think could easily be fixed.

----------------------------------------------------------------------
jmpessoa · 2013-12-29 16:40

@Leledumbo,

Congratulation!

I think this is very important because this approach can be applied in
others portings (mac ?)...

Thank You!

EDITED 1:

  I can apply like:

Code: [Select]  libname = {$ifdef android}'libGLESv1_CM.so'
                 {$else ifdef linux}'libGL.so'{$endif};
   this will work ?

EDITED 2: the changes was applied!
Quote     New! Support for Linux! Thanks to Leledumbo!
Quote     by Leledumbo for Linux users:
              1. Build all libraries in the 
../LazAndroidWizard/linux/dummylibs
              2. Put it somewhere ldconfig can find (or just run
ldconfig with their directories as arguments)

                "The idea of this is just to make the package
installable in the [Lazarus for Linux] IDE,

the libraries."

EDITED 3: well,  I  applied something more conservative:
Code: [Select]  libname = {$ifdef
linux}'libGL.so'{$else}'libGLESv1_CM.so'

ok?

----------------------------------------------------------------------
jmpessoa · 2013-12-29 22:13

Leledumbo · 2013-12-30 03:09

Quotelibname = {$ifdef linux}'libGL.so'{$else}'libGLESv1_CM.so'This
should be OK, since it's really intended for Linux system only.
However, if you want to support other OSes, this name must be adjusted
for each.

Have you tested it yourself anyway?

----------------------------------------------------------------------
jmpessoa · 2013-12-30 14:51

@Leledumbo,

QuoteHave you tested it yourself anyway?

Yes, I do. That is Ok for Windows...  yes, a more flexible solution is
need (what about mac?).  But, I  know the  "{$ifdef}" syntax  very
very little...

I've managed to create a project and it's running on a device. I can
put buttons and other stuff and works ok. In the onclick for a button
I did a showmessage and assigned some text to a textview,
unfortunately both actions result in a crash. The error is:

12-30 21:41:00.280: E/dalvikvm(4791): JNI ERROR (app bug): accessed
stale local reference 0x1ea00025 (index 9 in a table of size 7)

@zariq,  try  this change:

Old:

Code: [Select] object jButton1: jButton
    Id = 2238642
    PosRelativeToAnchor = [raAlignLeft]     <<<-----------

New:

Code: [Select] object jButton1: jButton
    Id = 2238642
    PosRelativeToAnchor = []     <<<----------- 

That is,  jButton1 do not have a anchor.... only parent.

EDIT 1: Yes, I got:

"

I'm trying to see what happened .... please, wait.



EDIT 2:

Yes, just some SDK/NDK/Laz4Android incompatibility!

Please, change AndroidManifest.xml

you have something like this:

android:targetSdkVersion="17"/>

Change simply to:
Code: [Select]<uses-sdk android:minSdkVersion="10"/>


Please, make this change in your template too:

Thank you very much! Fixed on GitHub.

My lfm got  got corrupted so deleted project. Having trouble getting
it to run this time round. Had different names for application and
activity wouldn't work, renaming  application to same as activity
solved it, but because of conflicts due to renaming have to create it
again. Will let you know when I get it going.

By the way should I download the new version or try it with the
current one.

thanks.

----------------------------------------------------------------------
jmpessoa · 2013-12-31 02:09

@zariq,

Ok.

What project model you is trying? Ant or Eclipse?

Thank you.

----------------------------------------------------------------------
zariq · 2013-12-31 02:11

Eclipse.

----------------------------------------------------------------------
jmpessoa · 2013-12-31 02:21

Ok.

When you are creating your app the Project name can be any.... only
the MainActivity needs to be nomead "App".

Thank you.

----------------------------------------------------------------------

Making the change in manifest works for showmessage. Thank you very
much.

Ok, it might have been paths or something.

----------------------------------------------------------------------
jmpessoa · 2014-01-02 05:53

Hi,

@zariq,

The problem is in using API > 13 (ex. android:minSdkVersion = 14),  I
think that is related to:

http://android-developers.blogspot.cz/2011/11/jni-local-reference-
changes-in-ics.html

I'm trying to find a solution!

Thank you!

EDIT: I update GitHub for a more conservative approach: the max for
"android:minSdkVersion" on AndroidManifest.xml now is "13"...

Meanwhile, I am seeking for a "true" solution......

EDIT#2: Good News! the bug was solved! more details later ....

----------------------------------------------------------------------
Leledumbo · 2014-01-26 11:34

Hi, jmpessoa. Could you name the wizard form variables (buttons,
checkgroups, radios, etc) meaningfully? I would like to change the
forms to comply with LCL autosize/layout. The forms may look good on
Windows, but on other platforms, they're messy.

Also some things for improvement:
Don't use -o in Others tab, use Target file name in Paths instead. And
make it to be ../libs/armeabi/libcontrols.so by default.Don't use -FU
in Others, use Unit output directory in Paths instead. And make it to
be lib by default (it would be a single target project
anyway)-FL<skip>libdl.so doesn't seem to be required anymore in recent
FPC

----------------------------------------------------------------------
jmpessoa · 2014-01-26 14:05

Hi Leledumbo,

Thanks for your suggestions ...

I'll see if I can make these changes ... in fact I'm still working (a
lot!) to overcome the BUG when API > 13.  

This is related here:
http://android-developers.blogspot.cz/2011/11/jni-local-reference-
changes-in-ics.html

I needed to re-engineer all the code ... but I think it is now almost
done.

Thank you!

----------------------------------------------------------------------
Leledumbo · 2014-02-05 14:35

The back on last (main) formseems to be buggy. The application does
exit, but actually it crashes. I can only get these two backtrace
lines:
Code: [Select]I/DEBUG   (  182):     #00  pc 000ad874 
/data/data/com.marsoft.piutangman/lib/libcontrols.so
(LAZ_AND_CONTROLS_$$_JAVA_EVENT_PAPPONBACKPRESSED$PJNIENV$POINTER+72)
I/DEBUG   (  182):     #01  pc 00023b6c 
/data/data/com.marsoft.piutangman/lib/libcontrols.so
(P$CONTROLS_$$_PAPPONBACKPRESSED$PJNIENV$POINTER+40)Looking at the
code:
Code: [Select]AForm := App.Forms.Stack[App.Forms.Index-1].Form;I'm
curious with App.Forms.Index, so I add:
Code: [Select]if App.Forms.Index <= 0 then App.Forms.Index := 1;before
that line, and the app doesn't crash but it can't exit as well. So I
guess the value is either 0 or less. That makes App.Forms.Index at
least -1, while App.Forms.Stack index starts from 0, that's the point
where the crash occurs.

I've tried remote debugging but it doesn't seem to work well. GDB says
libcontrols.so is missing debugging information, I've tried both stabs
and dwarf, neither works.

----------------------------------------------------------------------
jmpessoa · 2014-02-05 14:45

@ Leledumbo,

You are correct .... I also found this problem (and others ...),
please wait, I'll try to provide a more stable version later this week
with support for api > 13 .....

Thank you!

----------------------------------------------------------------------
jmpessoa · 2014-02-09 00:00

Hi All,

     I updated Android Module Wizard.

     version 0.4:: NEW! Add Support for Android API > 13.
        
      A lot of code lines was fix/changed/Added!

      Fix BackButton issue. Now all Forms close correctly.

     Please, see "readme.txt"  and "AppDemo1"  for others changes. 

     ref:  http://github.com/jmpessoa/lazandroidmodulewizard

     @Leledumbo: Now I will try your suggestions...

     Thanks to everyone!

----------------------------------------------------------------------
Leledumbo · 2014-02-09 02:36

Do you have any tutorial to use the And_jni(_bridge?) to create
wrapper for arbitrary Android API? I need to access sqlite, my app
would be highly database driven.

EDIT: Found a bug in the Ant demo App.java on line 5, the line should
be commented.

----------------------------------------------------------------------
jmpessoa · 2014-02-09 14:15

@ Leledumbo,

    Ok, I will write a "How To".

About:

Leledumbo · 2014-02-09 14:52

QuotePlease, which is the "text" of that line?[and Lazarus by
jmpessoa@hotmail.com - december 2013] <- it's not commented

I found another bug, the Ant demo is enough as a test app. Open the
app first, then exit by pressing back button. Then try to open the app
again. You'll get blank form instead. Another bug in
GetPathToJNIFolder, it will return relative path because the first
slash (root) will be trimmed as well. I change the routine body to:
Code: [Select]  i := Pos('src',fullPath);
  if i > 2 then begin
    Result := Copy(fullPath,1,i - 2); // we don't need the trailing
slash
  end else
    raise Exception.Create('src folder not found');because that's what
the routine is looking for from my analysis.

----------------------------------------------------------------------
jmpessoa · 2014-02-09 15:21

@Leledumbo,

Please, put the fixed GetPathToJNIFolder here.... I will fix my code
for linux Compatibility. Thank you!

@Leledumbo,

QuoteOpen the app first, then exit by pressing back button. Then try
to open the app again. You'll get blank form instead
Please, try this in ["Controls.java", line 4468] for all GUI Apps
Demos....

Code: [Select]       public  void appFinish () {
            activity.finish();
           System.exit(0);   // << ----------- Fix Here!
       }

Thank you.

----------------------------------------------------------------------
Leledumbo · 2014-02-15 11:13

QuotePlease, try this in ["Controls.java", line 4468] for all GUI Apps
Demos....OK, that works. Thanks.

Suggestion: Open tfpandroidbridge_pack.lpk->Package
Options->Usage->Add paths to dependent packages/projects->Library,
then add linux/dummylibs. This will make installation easier on Linux
but shouldn't hurt on Windows (but please test, I don't have windows).
Anyway, since these libraries are not meant to be used in actual
program, I think it's OK to provide a precompiled version of them in
the same directory. Or otherwise, provide additional instruction in
the readme / fast tutorial to compile these libs before installing the
.lpk.

Another question: how can I create a list view with custom content? I
want to create something like:
Code: [Select]<Name><TextView><CheckBox>
<Name><TextView><CheckBox>
<Name><TextView><CheckBox>
...
With the ability to add/remove the row anytime.

Last but not least: your demo .apk could run on at least 2.2, while
the one I built myself requires at least 4.0. Setting minsdkversion to
10 doesn't seem to work.

----------------------------------------------------------------------
jmpessoa · 2014-02-15 16:47

@Leledumbo,

I'm still here:

QuoteI need to access sqlite, my app would be highly database driven.
Yes, the support to Sqlite is almost ready! I think I can still
provide it this weekend. And then I will use it to write a "how to"...

Thank you!

----------------------------------------------------------------------
jmpessoa · 2014-02-16 18:47

Hi,

   I have made available a new update to Android Module Wizard.

   ref:  http://github.com/jmpessoa/lazandroidmodulewizard

   New!

    Added [Partial] Support to SQLite: 

    .New components: jSqliteDataAccess, jSqliteCursor.

   .Supported FIELD_TYPE at the moment::  INTEGER, STRING, FLOAT     

   .New Eclipse project demo:  AppSqliteDemo1

Thank you!

----------------------------------------------------------------------
Leledumbo · 2014-02-17 17:05

Alright, that's a nice start. I think that's enough for my
requirement.
Anyway, have you consulted with the developers about .lfm parsing
problem? I think it's appropriate to discuss in FPC mailing list,
since {$R support comes from the compiler. As an experiment, you might
want to test .lrs resources to see whether the problem also appears
there.
If you're OK, please give me write access so I can push my local
commits (github account name is the same as here: leledumbo).
I'm still waiting for the custom row on listview

Ok.  Please, see the picture [attachment] ....

What about?

----------------------------------------------------------------------
Leledumbo · 2014-02-23 04:44

Nice! I hope it's not a component by itself, creating the custom row
by code is OK for me, as long as I can mix widgets freely.

----------------------------------------------------------------------
jmpessoa · 2014-02-23 04:59

Well, as my first attempt I created some new properties to component
jListView: hasWigets {CheckBox or RadioButton or Button...} and too 
hasImage....

But, that is just a first attempt.... maybe I can create something
more flexible like
a property/component "jCustomRow".... 

I will try!

Thank you.

----------------------------------------------------------------------
Leledumbo · 2014-02-23 10:04

QuoteBut, that is just a first attempt.... maybe I can create
something more flexible like
a property/component "jCustomRow"....  One approach:
jListView can have a property called CustomRow of type "class of
jCustomRow". The user may extend the class with other widgets and
assign required callbacks.

Another approach:
jListView can have a property called CustomRow, containing a list of
widget. I have no idea whether object inspector already supports such
a mixed values, so this idea might be less visible than above
approach.

----------------------------------------------------------------------
jmpessoa · 2014-02-26 00:21

@Leledumbo

Please, clarify his [listview] row requirement. As it should
hypothetically be shown? if possible, use real information...

Thank you!

----------------------------------------------------------------------
Leledumbo · 2014-02-26 05:01

I want to build a row containing name and checkbox (as a sign that
this row is included in the selections) and a textview (for inputting
value). I'm creating an application to manage debts and claims, this
list will contain the people involved in an event that introduces the
debts and claims.

----------------------------------------------------------------------
jmpessoa · 2014-02-27 01:05

Ok,

Now we can get something like shown in picture [Attachment], where the
rows can be individually modified: image, text, text color, font size,
widget [check or radio or button or textview] etc.... and two events
can be  handled: list_item click an widget click.

Thank you!

jmpessoa · 2014-03-02 17:41

I got correct! See my picture [Attachment]. 

Well, I am using just emulator. I will continue testing!

Thank you.

Edit 1: OK, I got this error:

"E/AndroidRuntime(1100):
java.lang.ClassCastException:
android.widget.ImageView cannot be cast to android.widget.CheckBox"...

Just when image is clicked! I will fix this just now!  [BUG FIX !!]

Edit 2: I Will fix/synchronize java side items list and pascal side
items list for Add, Clear, Delete... etc... [FIX !!]


Edit 3:  I can modify the

OnClickItem signature: (Sender: TObject; Item: Integer);

To: (Sender: TObject; Item: Integer; itemText: string);

And

OnClickWidgetItem signature: (Sender: TObject; Item: integer; checked:
boolean);

To:
OnClickWidgetItem(Sender: TObject; Item: integer; itemText: string;
checked: boolean);

What about?

EDIT 4: [FIX EDIT_1 and EDIT_2].
            . Added New Method GetText(index: integer) to jListView.
            .updated AppDemo1...

Hi

@Fatih,

Thank you for your interest and enthusiasm and the TINIFile use
example.

In fact I'm working on a major improvement in Android Module Wizard
which will facilitate the implementation of new components.

The idea is that you will enter with the java [wrapper] class and
receive the pascal component code including the jni_bridge part.

Ok. I'll try to implement Menu object.

Thank you!

Stephano · 2014-04-13 22:14

Great work!

I am on Linux, and don't use Laz4Android, but have built Lazarus and
fpc accordingly from source.

1- Libraries issue: I made a quick workaround. Ex:

Code: [Select]{$IFDEF android}
  // jnigraphics
  function AndroidBitmap_getInfo(env: PJNIEnv; jbitmap: jobject; info:
PAndroidBitmapInfo): cint;
                                     cdecl; external libjnigraphics
name 'AndroidBitmap_getInfo';

 function AndroidBitmap_lockPixels(env: PJNIEnv; jbitmap: jobject;
addrPtr: PPointer {void**}): cint;
                                     cdecl; external libjnigraphics
name 'AndroidBitmap_lockPixels';

  function AndroidBitmap_unlockPixels(env: PJNIEnv; jbitmap: jobject):
cint;
                                     cdecl; external libjnigraphics
name 'AndroidBitmap_unlockPixels';
{$ELSE}
  function AndroidBitmap_getInfo(env: PJNIEnv; jbitmap: jobject; info:
PAndroidBitmapInfo): cint;

 function AndroidBitmap_lockPixels(env: PJNIEnv; jbitmap: jobject;
addrPtr: PPointer {void**}): cint;

  function AndroidBitmap_unlockPixels(env: PJNIEnv; jbitmap: jobject):
cint;
{$ENDIF}

implementation

{$IFnDEF android}
function AndroidBitmap_getInfo(env: PJNIEnv; jbitmap: jobject;
  info: PAndroidBitmapInfo): cint;
begin
  Result := 0;
end;

function AndroidBitmap_lockPixels(env: PJNIEnv; jbitmap: jobject;
  addrPtr: PPointer): cint;
begin
  Result := 0;
end;

function AndroidBitmap_unlockPixels(env: PJNIEnv; jbitmap: jobject):
cint;
begin
  Result := 0;
end;
{$ENDIF}

Another solution would be to use explicit loading of the libraries.

2- Java resources:
What are these?
I downloaded Simonsay's package. What next?

3- New project wizard: if something is missing (like ant workspace), 
I get an error message, but I have to repeat the whole procedure.

4- New project wizard: For ndk ver9, there is no API level 17 which I
use.

5- Why do you still use Lazarus resources instead of fpc resources?

I have other comments, but I'll keep them for later.

If you still need lazres for Linux, let me know and I'll email it to
you.

@Stephano,

1. Thanks for your interest!

2. About workaround on Linux:  please, look for
   @leledumbo advices in some previous posts and in folder 
.../LazAndroidWizard/linux   ("please_readme.txt"), and more generally
look for "readme.txt "IV. Technical Notes:..."

3.  Java resources: What are these? Please, just point/configure to
the folder   ..../LazAndroidWizard/java 
    (My modified version of simonsay's work is there! )

4. About ant workspace... just a base folder/reference for you
[folder] project code. Like Eclipse Workspace...

The others questions: I will try some fix...

Thank you!

Ps. Yes, please, send me the Linux executable "lazres". I need it to
produce component Icon resource.

----------------------------------------------------------------------
Stephano · 2014-04-14 08:40

I saw Leledumbo's post and the readme file. The 2 solutions that I
proposed are much cleaner and don't require any extra steps from the
user.

I was able to make a working app, but I found more issues:

1- Don't add any options in 'other options'. Instead use the 'Paths'
for -Fl -FU -o

2- Remove from other options -Xd -FL -Cf -P -dANDROID. -FL is not
needed (at least Leledumbo and I don't need it), and the other options
should be placed in fpc.cfg. This is debatable in order to accommodate
everybody's needs.

3- The batch files are Windows only. I can help you with Linux
scripts.

4- If the project name has capital letters (MyProject1), then strange
errors occur.

Note: I sent you an email with the resources utilities

----------------------------------------------------------------------
jmpessoa · 2014-04-14 13:06

@Stephano,

About 1 and 2: Yes, so my priority queue  allow, I will  improve it!

About 3. Yes, You can help me! Please, send me the Linux scripts which
mimics these *.bat!

About 4. Very strange indeed! I'll do some testing here...

note: yes, I received.

Thank You!

note: Please, send me the modified  *.pas with IFDEFs workaround!

Hi.

When I call from main module the java function (from Controls.java),
application crashes. What is problem?

Code: [Select]procedure TfrmMain.btnClick(Sender: TObject);
  var
  s: string;
begin

  s := jSysInfo_PathDat(app.Jni.jEnv, app.Jni.jThis, App.Jni.jThis);
  // or
  s := jSysInfo_PathDat(gapp.Jni.jEnv, gapp.Jni.jThis,
gapp.Jni.jThis);
  // or
  s := getPathDataBase(app.Jni.jEnv, app.Jni.jThis, App.Jni.jThis);
  ShowMessage(s);
  Exit;
end;

----------------------------------------------------------------------
jmpessoa · 2014-04-26 13:19

Hi Fatih,

Please, try my new: 

function GetFilePath(filePath: TFilePath): string;

Where:

TFilePath = (fpathNone, fpathApp, fpathData, fpathExt, fpathDCIM,
fpathDataBase);

Example:

  ShowMessage(GetFilePath(fpathApp));
  ShowMessage(GetFilePath(fpathData));
  ShowMessage(GetFilePath(fpathExt));
  ShowMessage(GetFilePath(fpathDCIM));
  ShowMessage(GetFilePath(fpathDataBase));  


Thank you!

----------------------------------------------------------------------
Fatih KILIÇ · 2014-04-27 07:04

Hi jmpessoa.

First thanks for you reply.

But my main problem is, when i "direct call" jSysInfo_PathApp,
jSysInfo_PathDat, jSysInfo_PathDataBase, jSysInfo_PathExt,
jSysInfo_PathDCIM (in the And_jni_Bridge.pas file) functions from my
main module, the application is crashes.

I want to write my code and improve And_jni_Bridge functions.
Generally context variables (in Controls.java) causing to crash.

Any idea for this problem.

----------------------------------------------------------------------
jmpessoa · 2014-04-27 16:04

Hi Fatih,

This is a more complicated question concerning the android API >13, so
I had to rewrite a lot of code in original Simon's  "Controls.java" to
overcome this difficulty .... To a better understanding of the
problem, please, read some previous post when I raised this issue ....

Thank you.

I know we can use the Lazarus/Android jButton, but as an exercise, I
want to create manually an android control using JNI and display it on
the form. Example:

MyClass := ...FindClass('Landroid/widget/button')
ConstructorID := ...GetMethodID(...)
MyButton := ...NewObject(...)

How can the button be placed on the form?

Hi All,

I finally got a major update for Lazarus Android Wizard.

It Now offers two new aid/assistance to increase the productivity of
coding.

1.You can now produce a almost complete pascal JNI component code from
a java wrapper class!
2.You can now get assistance for produce the java warapper class!


A proof of concept: New Components [Android Bridges Extra] and Demos
[Eclipse Projects]:

      jMyHello    [AppTryCode1]
      jMediaPlayer    [AppTryCode2]

      jTextFileManager,
                jDumpJavaMethods [AppTryCode3] //given a request and
suggestion of @Stephano


Please, read the new "fast_tutorial_jni_bridges_component_create.txt"
for more info!

ref: https://github.com/jmpessoa/lazandroidmodulewizard

Thanks for all!

For a first impression,  given a java wrapper class "jMyHello"

Code: [Select]class jMyHello /*extends ...*/ {        

        private long     pascalObj = 0;      // Pascal Object
        private Controls controls  = null;   // Control Class for
events
        private Context  context   = null;

        private int    mFlag;          // <<----- custom property
        private String mMsgHello = ""; // <<----- custom property
        private int[]  mBufArray;      // <<----- custom property

        public jMyHello(Controls _ctrls, long _Self, int _flag, String
_hello) { //Add more '_xxx' params if needed!

          //super(_ctrls.activity);
          context   = _ctrls.activity;
          pascalObj = _Self;
          controls  = _ctrls;

          mFlag = _flag;
          mMsgHello = _hello;
          mBufArray = null;
          Log.i("jMyHello", "Create!");         
        }

        public void jFree() {
          //free local objects...
           mBufArray = null;
        }

       //write others [public] methods code here......  <<-----
customs methods

        public void SetFlag(int _flag) { 
           mFlag =  _flag;  
        }

        public int GetFlag() {
           return mFlag;  
        }

        public void SetHello(String _hello) {
                mMsgHello =  _hello;  
        }

        public String GetHello() {
           return mMsgHello;  
        }
       
        public String[] GetStringArray() {
                String[] strArray = {"Helo", "Pascal", "World"};
            return strArray;  
        }
       
       
        public String[] ToUpperStringArray(String[] _msgArray) {
                int size = _msgArray.length;
                String[] resStr = new String[size];
                for (int i = 0; i < size; i++) {
                        resStr[i]= _msgArray[i].toUpperCase();
                }
            return resStr;  
        }
     
        public String[] ConcatStringArray(String[]  _strArrayA,
String[]  _strArrayB) {
       
                int size1 = _strArrayA.length;
                int size2 = _strArrayB.length;
       
                String[] resStr = new String[size1+size2];
       
                for (int i = 0; i < size1; i++) {
                  resStr[i]= _strArrayA[i];
                }
       
                int j = size1;
                for (int i = 0; i < size2; i++) {
                  resStr[j]= _strArrayB[i];
                  j++;
                }
       
            return resStr;
        }
       
        public int[] GetIntArray() {
                int[] mIntArray = {1, 2, 3};
            return mIntArray;
        }

        public int[] GetSumIntArray(int[] _vA, int[] _vB, int _size) {

           mBufArray = new int[_size];

           for (int i=0; i < _size; i++) {
              mBufArray[i] = _vA[i] + _vB[i];
           }
           return mBufArray;
        }
               
        public void ShowHello() {
           Toast.makeText(controls.activity, mMsgHello,
Toast.LENGTH_SHORT).show();          
        }       
}

Just a click and We can get:

Hi,

Given a suggestion and request by Fatih KILIÇ ... I made a minor
update
of  Android Module Wizard....

Now the Version 0.5 {rev. 01 - 06 May 2014} Add Partial Support for
Menu Object [Option Menu/SubMenu and Context Menu]....

      :: NEW jMenu Component [Android Bridges Extra]
      :: NEW AppMenuDemo [Eclipse Project]

Please, ref: https://github.com/jmpessoa/lazandroidmodulewizard

Thanks!

PS.

@Stephano: first we would need to define a new architecture:
application model, form model and component model.... soon as possible
I will try to investigate the way that you propose. Thank you!

----------------------------------------------------------------------
Fatih KILIÇ · 2014-05-07 07:29

Hi jmpessoa.

I have tested AppMenuDemo eclipse project. Very good work for me.
Thank you for your evaluates my suggestion and request.


Note:

When I select menu from title bar the menu and submenu is works fine,
but when i select menu from hardware MENU button the submenu can't
dispayed.

----------------------------------------------------------------------
Fatih KILIÇ · 2014-05-07 07:33

Also, i examine your wrapper class. Really that very big work. Good
works.

----------------------------------------------------------------------
jmpessoa · 2014-05-08 12:45

@ Fatih KILIÇ

Code: [Select]....when i select menu from hardware MENU button the
submenu can't dispayed....

Yes, the support for icon/drawable is very partial....

Please, verify that you have "ic_launcher.png" in all 
....\res\drawable-xxxx  folders.

Thank you.

Ok,

I'll try to see what's happening....

Thank you!

----------------------------------------------------------------------
Leledumbo · 2014-06-08 11:08

Works fine in 1.2.2, so I guess it's something changed in svn. It's up
to you though, whether you want to make it compatible or not.

----------------------------------------------------------------------
jmpessoa · 2014-06-08 17:13

Good News!

Thank you!

PS. I am working in next generation: the form designer is on the way!

----------------------------------------------------------------------

@Leledumbo,

Did you recompile the IDE clean? I did and the IDE aborts the
compilation (panic).

Yes, I build from fresh svn source and fresh 1.2.2 source using FPC
2.7.1 of quite recent (no less than a week) revision.

----------------------------------------------------------------------
Stephano · 2014-06-09 14:59

i used svn from 2 days ago. The IDE fails to build when this package
is installed.

----------------------------------------------------------------------
Leledumbo · 2014-06-09 16:21

Probably just an intermittent bug. Anyway, since it doesn't work as
well in lazarus svn, you don't have to try further. Stick with 1.2.2
instead.

----------------------------------------------------------------------
Stephano · 2014-06-09 19:32

Stable versions are for the faint hearted 

I hope this gets fixed soon.

----------------------------------------------------------------------
Leledumbo · 2014-06-11 16:17

@jmpessoa,

First, are you going to concentrate on the visual designer and abandon
the existing lazandroidmodule? Or will it be another package that
depends on lazandroidmodule?

Second, I have found a (probably) bug. wgRadioButton in ListView
doesn't act like a radio button. Selecting one doesn't deselect the
others and there's no way to set checked state from code. I see Java
code for this in Controls.java but jListView hasn't wrapped the method
yet.

Third, will you add Spinner? I need a combobox like structure. Right
now, I have to abuse list view a bit.

Last but not least, how do you create user defined dialog?

----------------------------------------------------------------------
jmpessoa · 2014-06-11 17:02

Hi Leledumbo,

1. No, I am not will abandon the existing lazandroidmodule. The
existents projects will load in the next generation.

2. I will return to jListView  code and try fix this bug.

3. I wil try implement the Spinner.

4. how do you create user defined dialog? The paradigm is the same:
Java warapper (added to "controls.java") and Pascal "bridge"
Component. I Will try
implement an example.

Thank you!

PS: "For all"

Just of curiosity : Someone tried to build your own component?

Lazarus Android Wizard now offers two new aid/assistance to increase
the productivity of coding.

1.You can now produce a almost complete pascal JNI component code from
a java wrapper class!
2.You can now get assistance for produce the java warapper class!

Please, read the new "fast_tutorial_jni_bridges_component_create.txt"
for more info!

Thanks for the update. One more thing, could you research on how to
handle Java exceptions? ATM, every Java exception will crash the app
so we need a mechanism to handle it. Pascal exceptions can of course
be handled by Pascal code.

----------------------------------------------------------------------
jmpessoa · 2014-06-14 23:37

All],

Hmm...not yet so far, just that exception handling.
I have a little improvement idea, not in the code, but the build
process. You can run ProGuard since not all classes, methods, etc. are
used. This can reduce the final result size.
I want to ask one thing, how to use toast? It's a bit unclear to me.
It should be a class with class method in the Android Java
documentation.

----------------------------------------------------------------------
jmpessoa · 2014-06-19 12:59

@Leledumbo,

Code: [Select]....You can run ProGuard since not all classes...

Nice! great info!

Quotehow to use toast?
I implemented the standard "ShowMessage" as a jForm method:

line: 417
Code: [Select]public void ShowMessage(String msg){
        Log.i("ShowMessage:", msg);
        Toast.makeText(controls.activity, msg,
Toast.LENGTH_SHORT).show();
}

Where "controls.activity"  is the "fresh"  java Context  maintained
over the entire framework designer ...

You can put this code:
Code: [Select]Toast.makeText(controls.activity, "my message",
Toast.LENGTH_SHORT).show();

 inside any method for other jobjects in "Controls.java"! See lines
5024/5120 [jMyHello]

For jForm Pascal side there is:

Quoteprocedure jForm.ShowMessage(msg: string);
begin
  UpdateJNI(gApp);  // << ---- "refresh" Context!
  jForm_ShowMessage(Self.App.Jni.jEnv, Self.App.Jni.jThis,  FjObject,
msg);
end;

Where the last is the Pascal JNI API:

Code: [Select]procedure jForm_ShowMessage(env:PJNIEnv; this:jobject;
Form:jObject; msg: string);
var
   cls: jClass;
   method: jmethodID;
    _jParams : Array[0..0] of jValue;
begin
   _jParams[0].l:= env^.NewStringUTF(env, pchar(msg) );
  cls := env^.GetObjectClass(env, Form);
  method:= env^.GetMethodID(env, cls, 'ShowMessage',
'(Ljava/lang/String;)V');env^.CallVoidMethodA(env,            Form,
method,@_jParams);
  env^.DeleteLocalRef(env,_jParams[0].l);
end;

Thank you!

PS1. In future we may consider including  in the template
"Controls.java" [in designe time] only the classes used by project...
so we will have more custom Apps.

PS2. The next generation [form designer] is coming soon! Will be much
more fun to program for android!

Hi,

When I set jTextView.Text property by turkish characters set, the
characters's view is incorrect. Is this a bug?

How do I solve this problem?

Note: The .pas file is saved in UTF8 format.

Code: [Select]jTextView.Text := 'İETT Otobüs Sefer Bilgisi (iettosb),
İETT''nin yurt içi taşımacılığı...';

Screen View:
İETT Otobüs Sefer Bilgisi (iettosb), İETT''nin yurt içi
taşımacılığı' +

Source file encoding must be UTF8. Try with our without BOM. Debug in
assembly. Check if there is no conversion routine called like
fpc_ansi_str* or similar.

----------------------------------------------------------------------
Fatih KILIÇ · 2014-07-09 12:37

Thanks tk. As you said, I removed related section and problem solved.

File: Laz_And_Controls.pas

Code: [Select]Procedure jTextView.SetText(Value: string);
begin
  FText:= Value; //utf8encode(Value);  // Removed.
  if FInitialized then
    jTextView_setText2(jForm(Owner).App.Jni.jEnv,
jForm(Owner).App.Jni.jThis, FjObject, FText);

Hi.

Q1.
My there are two form. First form (TAndroidModule1) opens second form
(TAndroidModule3). Second form must result value to the first form.
Below codes is insufficient. How two form are synchronize the value?
(global.SelectedHat)

Form1
Code: [Select]procedure
TAndroidModule1.DataModuleClickContextMenuItem(Sender: TObject;
  jObjMenuItem: jObject; itemID: integer; itemCaption: string;
checked: boolean
  );
begin

  if(itemID = 10) then
  begin

    if(AndroidModule3 = nil) then
    begin

      gApp.CreateForm(TAndroidModule3, AndroidModule3);
      AndroidModule3.Init(gApp);
    end else AndroidModule3.Show;
  end;

  // global variable
  edtHat.Text := global.SelectedHat;
end;

Form2
Code: [Select]procedure
TAndroidModule3.jListView1ClickCaptionItem(Sender: TObject;
  Item: integer; caption: string);
begin

  // global variable
  global.SelectedHat := caption;

  Close;
end;

Q2:
Second problem is when add item jListView above 512 the program is
crach. Error is: "E/dalvikvm(3819): Failed adding to JNI local ref
table (has 512 entries)"

How resolve these problem. Thanks.

Thanks jmpessoa

jListView1.Add problem is solved. Also i'm waiting updated
lazandroidmodule for global unit.

A suggestion: improving of ListView widget will helpful.

----------------------------------------------------------------------
jmpessoa · 2014-09-06 12:09

Hi Fatih, about Q1:

No, there will be NO update for global unit .... I just tried to redo
the path that you were trying to do .... and managed to get the
expected result! For test  I just used this code:

Code: [Select]unit Global;

{$mode delphi}

interface

uses
  Classes, SysUtils;

var

  SelectedHat: string;

implementation

end.

Thank you!

----------------------------------------------------------------------
Fatih KILIÇ · 2014-09-07 08:13

Hi, jmpessoa

When I click TAndroidModule3.jListView
(TAndroidModule3.jListView1ClickCaptionItem) the Form2
(TAndroidModule3) is closed, global.SelectedHat variable is empty and
edtHat.Text (jEditText) control value is showing blank value.

I think there are synchronize problem? I could not find a solution.

Thank you.

----------------------------------------------------------------------
jmpessoa · 2014-09-07 18:52

Hi Fatih, please, try this:

Code: [Select]Unit3

interface
 
............................
............................

implementation

uses Unit1;   //< ------ put it!

procedure TAndroidModule3.jListView1ClickCaptionItem(Sender: TObject;
  Item: integer; caption: string);
begin

  // global variable
  global.SelectedHat := caption;

  Unit1.edtHat.Text := global.SelectedHat;  ////< ------ put it!

  Close;
end;

Thank you!

PS. As soon as possible, I will try a more architectural
synchronization solution!

EDITED: Ok, here's a more elegant solution:

Code: [Select]TAndroidModule1 = class(jForm)

    private
      {private declarations}
    public
      {public declarations}
      Procedure MyCallBack(Sender: TObject);  //<--- your call back
function!
end; 

implementation

Procedure TAndroidModule1.MyCallBack(Sender: TObject);
begin
   jEditText1.Text:= global.SelectedHat;
end; 

procedure TAndroidModule1.DataModuleClickContextMenuItem(Sender:
TObject;
  jObjMenuItem: jObject; itemID: integer; itemCaption: string;
checked: boolean);
begin

  if(itemID = 10) then
  begin

    if(AndroidModule3 = nil) then
    begin
        gApp.CreateForm(TAndroidModule3, AndroidModule3);
        AndroidModule3.SetCloseCallBack(MyCallBack, nil);  //<<--
[delphi sintaxe mode]!
        AndroidModule3.Init(gApp);
    end else AndroidModule3.Show;
  end;

  // global variable
  //edtHat.Text := global.SelectedHat; //<<---- this line never was
called!
end;


Thank you!

----------------------------------------------------------------------
Fatih KILIÇ · 2014-09-08 08:00

Hi, jmpessoa.

Different and interesting a solution but synchronization solution is
more beautiful.

I wish you continued your work.

Thank you.

========================
NOTE: LATER ADDED SECTION

Bug: EditText1Change events is not triggers.

Code: [Select]procedure TAndroidModule3.jEditText1Change(Sender:
TObject;
  EventType: TChangeType);
begin

  case EventType of

    ctChangeBefore: ShowMessage('ctChangeBefore event occurs');
    ctChange: ShowMessage('ctChange event occurs');

some of Android Module Wizard components' property and method is
missing ,will add them?for example jbitmap is not have savetostream
and loadfromstream.

----------------------------------------------------------------------
jmpessoa · 2014-09-20 22:32

Yes, greenzyzyzy

Whenever possible (time is always a important variable ...) I will
implement new methods and properties to all components...

Specifically, if you point out the context in which you need to use
jbitmap it would be important. I can try implement your request...

Thank you!

----------------------------------------------------------------------

Hello,

I have a question about Laz4android. Can I use the offical build
Lazarus(now 1.2.4 with FPC 2.6.4)?
Or you build is a must.

Thanks,
Stygian

----------------------------------------------------------------------

sorry i do not know,because i am a newer too.

----------------------------------------------------------------------
jmpessoa · 2014-09-25 16:23

No,  You will need fpc 2.7.1 + cross arm/x86  libs for android.....

the simplest way is to get this one:

https://sourceforge.net/projects/laz4android/files/?source=navbar

Lazarus 1.2.4 is OK, but FPC must be 2.7.1 since 2.6.4 contains no
proper Android support.

----------------------------------------------------------------------
Stygian · 2014-09-25 17:50

Thanks for the answer. Maybe others already said it but there is a bug
in the Android Modul configure window. The Ant and SDK browse buttons
are swapped.

Hi,
I played with android during 1 week, using Android Module Wizard.
Very nice tool !
I'm using the ant process to compile and build apk.
I have questions about themes. I'm trying using the Holo theme light,
but i always have froyo style interfaces. Did someone succeeded to
apply native theme (i targeted android 4.4 in sdk target).
And what about strings.xml, i don't know if it's possible to get
values from strings.xml to have multi language interfaces. If it's
possible and if someone has a piece of code to show...
Thanks in advance

Thanks in advance
Since AMW use LCL style resources, I think you should use the same
approach for multilingual apps. The same way as the desktop apps. The
problem is everytime you change strings.xml, R.java is automatically
regenerated and you will need a dynamic JNI wrapper to be able to call
the entries in the R class. It's not impossible, but you will need
R.java JNI wrapper.

----------------------------------------------------------------------
jmpessoa · 2014-10-11 16:03

Hi,

@thierrydijoux,

You can try modify this line,

Code: [Select] android:theme="@style/AppTheme" >

in "AndroidManifest.xml"

Well, You can try change "styles.xml" too:  [
.....\res\values\styles.xml ]

@Leledumbo, you got played with new "form designer" version? 

Thanks!

----------------------------------------------------------------------
thierrydijoux · 2014-10-11 19:37

@jmpessoa and @Leledumbo :Thanks for your reply

@Leledumbo : how can i have or genrate the R.java JNI wrapper ? I
think it's the same thing for all resources (bitmap etc).
Managing translations in the generated .so is not really a problem,
but managing bitmap for different screens resolutions can be tricky. I
think the R.java JNI wrapper could be quite usefull.

@jmpessoa : have you try to access the android actionbar with fpc ?

The same as creating other JNI wrapper. jmpessoa should be able to
tell you what to do to create a JNI wrapper in general with his AMW.

A curiosity, if I have a project already created how can I bring up
the configuration wizard for android?

----------------------------------------------------------------------
jmpessoa · 2014-10-12 20:03

@xinyiman, sorry, I do Not understand!

An old Eclipse project?

An old Eclipse project + LazWizardModule project?

----------------------------------------------------------------------
xinyiman · 2014-10-13 13:03

For example, if I want to change the setting of '"Android Module
Wizard" to one of the examples that you make available to learn. How
can I do?

----------------------------------------------------------------------
jmpessoa · 2014-10-13 17:17

Hi xinyiman,

The example projects do not depends of the "Android Module Wizard"
configuration [paths etc..]... if you install is ok, then just open
the lazarus project in "\jni" folder ["controls.lpi"] .... now you can
modify it!

To produce new modified android Apk

1. Just use eclipse to import the example project .... after do 
"->refresh"  and "->run" it!

2. Or just use java "ant"  utility.....

Thank you!

----------------------------------------------------------------------
xinyiman · 2014-10-14 10:48

ok, but when I go to "Build" tells me that there is no output folder

C:\adt32\eclipse\workspace\AppSqliteDemo1\jni

Where do I go to change the destination folder?

----------------------------------------------------------------------
jmpessoa · 2014-10-14 17:53

Hi  xinyiman,

1. Is you using eclipse?

2. You imported the project to eclipse?

3. If  (1 and 2) = yes, then open the lazarus project and "save all"
to the new \jni path....

4. Go to Lazarus IDE

->Project

->Project -> Option

->Path

Change this information for correct one!

"C:\adt32\ndk7"

"C:\adt32\eclipse\workspace"

Thank You!

PS.

According to me you could create a virtual machine that has as its
sole purpose is to create Android applications with this tool. It
would be good to do it in linux (any version). Because the end user to
program interesting and not realize the development environment. What
do you say, someone wants to do it? But then to be kept up to date. I
guarantee that many would use it.

----------------------------------------------------------------------
Fred vS · 2014-10-18 21:31

Hello 

Are you using/testing Android on VirtualBox ?

I have install android-x86-4.4-RC1.iso on VirtualBox-linux-Mint/64bit,
it works sometimes but it has lot of crash too. 

Do you have a better iso ?

Thanks.

----------------------------------------------------------------------
jmpessoa · 2014-10-19 01:12

@xinyiman,
@Fred vS

I do not use virtual machine/box.... I have not thought about this
possibility or necessity...

1. To make android App:

-----On windows you can try:

LiteZarus4Android [Lazarus 1.3 + x2nie patch [No LCLform design] +
TrueTom fpc 2.7.1 cross Arm/x86/android/]

:DOWNLOAD from:
https://onedrive.live.com/redir?resid=78D6F726E8F0C522%21236 [right
click to download!]

:To Install, please, read the "LiteZarus4Android_readme.txt"

----On Linux: get Lazarus 1.3 rev >= 45216,45217 ... and fpc 2.7.1
cross /arm/x86/android ... etc.

2. To Run/Test App:

-->> Emulator
-->> Real Device [my is Galaxy S3 / android 4.3]

Greetings!

i got the same problem,if i do not want to use LiteZarus4Android,can i
mark this codes  out?

----------------------------------------------------------------------
jmpessoa · 2014-10-19 03:11

Well, you just need Lazarus 1.3 rev >= 45216,45217

But,  LiteZarus4Android [win32]  is a cross compile package!

     = Lazarus 1.3 rev >= 45216,45217  +
        TrueTom fpc 2.7.1 cross Arm/x86/android/  [for NDK 9b]

Greetings!

PS. Precisely the  [@x2nie] patch is a contribution to No LCLform
design ["GetObjInspNodeImageIndex" ... etc ]!

Clicking OK in the wizard (after filling required fields) terminates
IDE instantly. Lazarus svn 46619, FPC svn 28884. I'll try to get a
proper backtrace.

Hello guys I'm doing some tests to start from scratch with a project.
And when I create a new project I create the file controls.lpr fact,
when I create the package apk and install it on my smart phone will
not let me open. Who tells me why?

I used the settings for gingerbread.

----------------------------------------------------------------------
xinyiman · 2014-11-02 17:12

So I'm making progress, I installed everything. I tried to create a
blank application and I build the apk file. If I add a button that
launches a ShowMessage goes wrong. Download soirce :

www.lazaruspascal.it/download_personali/prova_tel.zip

Who tells me why?

----------------------------------------------------------------------
jmpessoa · 2014-11-02 18:13

Hi  xinyiman,

A strange thing I noticed in your code "Unit1.lfm" :

Code: [Select]Anchor = jButton1
Try remove this settings [go to Object Inspector and set this property
to (none)/blanck]

I think, it can not be anchored himself!

But it can be "anchored" to the parent, example:

set property PosRelativeToParent = [rpCenterInParent]

Thank you!

----------------------------------------------------------------------
xinyiman · 2014-11-02 19:04

I've already tried that ... the apk file I create it but when
compiling it says that my source has errors

----------------------------------------------------------------------
jmpessoa · 2014-11-02 19:13

Ok, can you put here the "error message"?

----------------------------------------------------------------------
xinyiman · 2014-11-02 19:23

How do I? There are practical Eclipse

Ok,

You're trying to build "Apk" using "ant"  [build.bat] ?

If  true, go to  "build.xml"  and try:

Code: [Select]<property name="target"  value="android-17"/>

----------------------------------------------------------------------
xinyiman · 2014-11-02 22:34

how build apk using ant?

----------------------------------------------------------------------
jmpessoa · 2014-11-02 22:53

Open  "build.xml"  and change to:  [all in project folder!]

Code: [Select]<property name="target"  value="android-17"/>

Simply run "build.bat"  --->> build Apk
Simply run "install.bat"  --->> install Apk on device or emulator

The gingerbread is the question!

Please,  go to AndroidManifest.xml

change to: [9 or 10?]
Code: [Select] <uses-sdk android:minSdkVersion="9"
android:targetSdkVersion="17" /> 

Please,  go to  "...\res\values"  folder

change "styles.xml" to:

Sorry, I do not have a gingerbread device to test it!

Hi xinyiman,

I tried to mimic their project and everything went as expected: build
[.so], build apk, install apk and run it!

You can use this link to compare and perhaps you will discover what
you're doing....

I solved the problem by copying the folder / res of your project in my
project. And it worked. Of course I went to change his name of the XML
file appropriately.

Thank youuuuuuu

I have a problem when drawing components on androidmodule the
following properties do not change based on where I move the
component. In someone else happen?

The properties are:

MarginBottom, MarginLeft, MarginRight, MarginTop

----------------------------------------------------------------------
jmpessoa · 2014-11-04 11:19

Yes, this properties has this limitation in  drawing,  maybe I'll
still make this better ...

But their values ​​are considered in run time!

Edited: a remark, this properties manages the inside component space
(pad) not the localization concerning to the form!

----------------------------------------------------------------------
xinyiman · 2014-11-05 09:02

So in practicing with this wonderful tool I was able to create a
database, a table, insert 4 records ... but when I try to view the
records I go wrong. Here you will find the project:
www.lazaruspascal.it/download_personali/provaace.zip

Who tells me where am I wrong?

----------------------------------------------------------------------
jmpessoa · 2014-11-06 11:25

Hi  xinyiman,

You can do:

Code: [Select]  ShowMessage(IntToStr(rows.Count)) ;

Is the correct count?

----------------------------------------------------------------------
xinyiman · 2014-11-12 08:34

I tried to do as you say, but it continues to go wrong. Ideas?

Code: [Select]procedure TAndroidModule1.jButton2Click(Sender:
TObject);
var
  rows: TStringList;
  i: integer;
begin


          try
             try
                rows:= TStringList.Create;
                rows.StrictDelimiter:= True;
                rows.Delimiter:= jSqliteDataAccess1.RowDelimiter;
                rows.DelimitedText:= jSqliteDataAccess1.Select('SELECT
* FROM '+  FTableName);
                {for i:= 0 to rows.Count-1 do
                begin
                  ShowMessage(rows.Strings[i]);
                end;}
                ShowMessage(IntToStr(rows.count));
                rows.Free;

             finally
                    //codice da effettuare a fine procedura sia che va
bene il codice sopra sia che il codice ha sollevato un'eccezzione
            end;
          except
                on E: Exception do
                begin

                   //codice da eseguire solo se si verifica un
eccezzione
                   showmessage(e.Message);
                end;
          end;



end;

----------------------------------------------------------------------
jmpessoa · 2014-11-12 15:31

Quote...continues to go wrong..
Code: [Select]              {for i:= 0 to rows.Count-1 do
                begin
                  ShowMessage(rows.Strings[i]);
                end;}

                ShowMessage(IntToStr(rows.count));   // <<-----


Ok, Can say what "count" you got?

----------------------------------------------------------------------
xinyiman · 2014-11-12 19:39

then did more tests ... if this code is not working

FTableName=atleti


Code: [Select]procedure TAndroidModule1.jButton2Click(Sender:
TObject);
var
  rows: TStringList;
  i: integer;
begin
          try
             try
                rows:= TStringList.Create;
                rows.StrictDelimiter:= True;
                rows.Delimiter:=jSqliteDataAccess1.RowDelimiter;
                rows.DelimitedText:=jSqliteDataAccess1.Select('SELECT
* FROM '+  FTableName + ';');
                for i:= 0 to rows.Count-1 do
                begin
                  ShowMessage(rows.Strings[i]);
                end;
                rows.Free;
             finally
                    //codice da effettuare a fine procedura sia che va
bene il codice sopra sia che il codice ha sollevato un'eccezzione
            end;
          except
                on E: Exception do
                begin

                   //codice da eseguire solo se si verifica un
eccezzione
                   showmessage(e.Message);
                end;
          end;
end;



so does work


Code: [Select]procedure TAndroidModule1.jButton2Click(Sender:
TObject);
var
  rows: TStringList;
  i: integer;
begin
          try
             try
                rows:= TStringList.Create;
                rows.StrictDelimiter:= True;
                rows.Delimiter:=jSqliteDataAccess1.RowDelimiter;
                rows.DelimitedText:='ciao#caio#sempronio#pippo#90';
                for i:= 0 to rows.Count-1 do
                begin
                  ShowMessage(rows.Strings[i]);
                end;
                rows.Free;
             finally
                    //codice da effettuare a fine procedura sia che va
bene il codice sopra sia che il codice ha sollevato un'eccezzione
            end;
          except
                on E: Exception do
                begin

                   //codice da eseguire solo se si verifica un
eccezzione
                   showmessage(e.Message);
                end;
          end;
end;

this is the line that creates problems. I do not understand ...

jSqliteDataAccess1.Select('SELECT * FROM '+  FTableName + ';');

----------------------------------------------------------------------
jmpessoa · 2014-11-12 20:29

Code: [Select]jSqliteDataAccess1.Select('SELECT * FROM '+  FTableName
+ ';');

Yes,  Try cut out the ";" for both:

jSqliteDataAccess1.Insert

and

jSqliteDataAccess1.Select

----------------------------------------------------------------------
xinyiman · 2014-11-12 20:51

tried, nothing changes. ideas?

----------------------------------------------------------------------
jmpessoa · 2014-11-12 21:21

before

Code: [Select]    jSqliteDataAccess1.Select('SELECT * FROM '+ 
FTableName);

try 

Code: [Select]   rowCount:= jSqliteDataAccess1.Cursor.GetRowCount;
   ShowMessage('rowCount= '+ IntToStr(rowCount));

That is ok?

----------------------------------------------------------------------
xinyiman · 2014-11-12 21:42

rowcount=0

----------------------------------------------------------------------
jmpessoa · 2014-11-12 21:55

So we can think the insert command failed .... why?

 You can try again the Insert without the ";"  terminator?

Edited:

comment this, too:
Code: [Select]     //jSqliteDataAccess1.DeleteFromTable('delete from '
+ FTableName + ';');  // <<-----

----------------------------------------------------------------------
xinyiman · 2014-11-13 07:03

No change, no more input. I do not understand why

----------------------------------------------------------------------
jmpessoa · 2014-11-14 07:58

Hi  xinyiman, you can try use "AppSqliteDemo1" as is? Well,  you need
modify some Project settings [paths]...

But I wil continue trying to find why your code fails ..

says:

"parsing error
problem with the analysis of the package"

This is the link to where you find the project with the changes made

You tell me what's wrong? Also for gingerbread. thanks

I updated the workspace dialog to use anchors & autosizing so it looks
good on all platforms. Please check though, I only have Linux.
Currently, there's still crash after flling the dialog, after asking
for Laz4Android location (I don't think it's required). I'm still
investigating.

@ Leledumbo,

Yes, we need "lazbuild" to rebuild ".so" in "LATE" [IDE plugin]...

Thank you!

EDITED:

1. @xinyiman: I will test it!

2.Roadmap: I'm finishing support to ActionBar! and a complete redesign
of jMenu component (and NEW jContextMenu) with total support to it and
Icons!

lazbuild is part of lazarus, not laz4android, so it should be
deducible automatically.

----------------------------------------------------------------------
Leledumbo · 2014-11-26 07:41

Finally, it works with Lazarus trunk on Linux. I can create a project,
but somehow I can't drop any component on the module. Any component on
any palette will redirect me to standard tab with no component
selected. Existing projects, such as the demos, can be opened and I
can see the form designer with components rendered fine. Same problem
with dropping new components, though.

Weird thing is that I can drop components from android bridge tab to
lcl form, but not on android module. Maybe I should try on stable
lazarus.

EDIT:
It's a regression.

Hello, jmpessoa. As more features are added, lazandroidmodule becomes
bigger and bigger. Even hello, world now eats nearly 1 MB apk (with
.so itself eats 2.6 MB uncompressed). Do you think it's the time to
refactor the code so only needed ones get linked in?

----------------------------------------------------------------------
jmpessoa · 2014-12-20 17:01

@Leledumbo

Quote...  .so itself eats 2.6 MB uncompressed ...
I agree with you. From Pascal side I can do the this task just now...
If you can point out some bottleneck and offer any suggestions will be
very well accepted!

Thank You!

Nice work jmpessoa!

Hints:
- please can you include in first post Fast tutorial? (from third
page?). Its hard to find how to start.
- maybe fast_tutorial_eclipse_users.txt isn't good naming, when I
downloaded zip, I spend half hour searching for install instructions.
What about rename it to eg.: install_tutorial_eclipse_users.txt
(install* is important )

----------------------------------------------------------------------
jmpessoa · 2014-12-21 17:58

Hi All!

There is a updated revision of  "Android Module Wizard"

Version 0.6 - rev. 10 - 21 December 2014 -

   Important Code Reorganization: A sugestion by Leledumbo [Thank you
very much Leledumbo!]

   Significantly reducing the final size of "controls.so"  [just about
half!]

   Typical example:
Code: [Select]  TAndroidModule1 = class(jForm)
                jButton1: jButton;
                jEditText1: jEditText;
                jListView1: jListView;
                jSpinner1: jSpinner;
                jTextView1: jTextView;
                procedure jButton1Click(Sender: TObject);
        private
                {private declarations}
        public
                {public declarations}
        end;

   Before:
      controls.so  --------- 2768 KB

   After code reorganization:
      controls.so ---------- 1371 KB

do, but you already strip it down to half in size!

Hi there!

There is a updated revision of  "Android Module Wizard"

ref. https://github.com/jmpessoa/lazandroidmodulewizard

Version 0.6 - rev. 11 - 03 January 2015 -

   .Major Code Reorganization/Cleanup [Pascal and Java sides]:

   .WARNIG! you need [must] upgrade your existing code/application!
      Please, use the IDE "tools" -> "Android Module Wizard" ->
"Upgrade Code Templates"

   .Reducing the final size of "controls.so"  [now less than half!!]

   Typical example:
Code: [Select]  TAndroidModule1 = class(jForm)
                jButton1: jButton;
                jEditText1: jEditText;
                jListView1: jListView;
                jSpinner1: jSpinner;
                jTextView1: jTextView;
                procedure jButton1Click(Sender: TObject);
        private
                {private declarations}
        public
                {public declarations}
        end;
        ..............................
   Before [Typical example]:
      controls.so  --------- 2768 KB

   After first code reorganization [Typical example]:
      controls.so ---------- 1371 KB

   Now [Typical example]:
      controls.so ---------- 1206 KB  [!!]

   How it scale? The "AppDemo1" uses 14 forms and many, many
components and code:
      controls.so ---------- 1379 KB  [Added only 14% !!]

   FIX/NEW! jEditText
      :: New! Added event property "OnChanged"         
      :: FIX/NEW! Event handles now is OK with help of the news
methods
         "DispatchOnChangeEvent" and "DispatchOnChangedEvent"!
      :: FIX! InputTypeEx property now is ok!

   NEW! Demo AppEditTextDemo1 [Eclipse Project...]  
                               
   WARNIG! jEditText property name "LineMaxLength" changed to the
correct "MaxTextLength" !
      .Please, no panic! When prompt "Read error" [Unknown Property]
just choice "Continue Loading"!
      (simulates some component property change e save it!)

   WARNIG! jImageView lost the property "IsBackgroundImage"
      .Please, no panic! When prompt "Read error" [Unknown Property]
just choice "Continue Loading"!
      (Simulates some component property change e save it!)
      .Just puts the jImageView "first" on jForm and set LayoutParams
[H/W] to lpMatchParent
         (Form Background Image is done!)


Thanks to All!

Gentlemen, anyone could look at this ? The use of Lazarus Android
Module Wizard components on Linux, Ubuntu 14.04 64 bit

https://github.com/jmpessoa/lazandroidmodulewizard/issues/1

The steps are correct ?

Hello guys, I want to prepare a virtual machine (linux) with
everything already installed. I want to know the right steps to do

1. Install the Java JDK
2. Install Android-study
3. Install ndk
4. Install Lazarus
5. Install the compiler arm-android (which guide I follow?)

What else?

2 -> Install Android sdk, anything else but the sdk is useless for
development with this package
5 -> any guide that can help you create arm-android cross compiler,
the Android wiki article should have the pointer
what else -> clone and install the package

And for colors, I need do this:
Code: [Select]jTextView1.BackgroundColor := $FF2C2F3E;
For testing I created code like this and it's working:
Code: [Select]....
   procedure SetBackColor (Value: DWord);
...
    property BackgroundColor     : TARGBColorBridge read FColor   
 write SetColor;
    property BackColor: DWord read FBackColor Write SetBackColor;    
 

...


procedure jTextView.SetBackColor(Value: DWord);

  FBackColor:= Value;

Hello

Thank you for Your work.

I have made a small calculator for my purpose.
Working time about 2 weeks  with studying and drawing.

Project properties
ANT
SDK tool Built 21.1.2
NDK 10C
Android 14
Target Android-17

I can give you the link on the result of me work if you are interested
in it.

There were some difficulties.
I have some suggestions about the future versions, if it is possible
to produce.
Sorry for non-professional description of the problems and advice. I
am a chemist.

1. Failed to delete <uses-permission
android:name="android.permission.READ_PHONE_STATE"/>. The app crashes.


2. For displaying  data from database and SQL queries used spinner

- spinner does not show more than 80-100 items (depends on number of
characters), the app crashes;
- does not «count», and almost all properties and procedures  «item».
-  need the event   “onclick”  without selection;
- need «fontsize»;

3. «Jedittext»
- need the property «readonly» type;
- need an event type «onexit»;
- if форm 8 “Jedittext” with “maxtextlengh =300”, the app crashes;

4. Form.
- if create a form with “actRecyclable” or “actSplash” from form with
“actRecyclable” or “actSplash” (3 form), does not work «backbutton» in
the first form with “actMain”;
- Could not make FreeAndNill to form with «actRecyclable» or
«actsplash».

5. The problem with string concatenation.
- this code does not work

var
A:real;
.....
stringlist:=tstringlist.Create;
stringlist.Add(A = '++floattostrf(A,ffFixed,10,2));
stringlist.free

it works

var
string_add:string;
.....
stringlist:=tstringlist.Create;
string_add:='A =';
string_add:= string_add +floattostrf(A,ffFixed,10,2);
stringlist.Add(string_add)
stringlist.free;

Yes, I am interested! We can put it as "demo" ....

Ok, I will try fix and implement your suggestions!

Thank you!

----------------------------------------------------------------------
rx3.fireproof · 2015-02-15 16:23

Ok

The result here  https://yadi.sk/d/MozLnxSpeieyu


If you need the source for the demo, I will remove the math and will
send the source via e-mail (e-mail?)
Code not a professional, I'm not a programmer.

@rx3,

Great and nice work!

The demo need just GUI prototype... the math can be replaced by simple
"ShowMessage"... So other people can learn to model a "Lamw"
application.

Thank You.

----------------------------------------------------------------------

Hi rx3!  [and All  ]

I tried attend some of his suggestions! So you can improve your nice
project!

ref.  https://github.com/jmpessoa/lazandroidmodulewizard

Version 0.6 - rev. 15 - 17 February 2015 -

   MINOR IMPROVEMENTS:

   jApp:
      LOST properties: // <<--A suggestion and request by
rx3.fireproof   
         Device.PhoneNumber
         Device.ID;
   jForm:
      NEWS methods:   
         .GetDevicePhoneNumber;
         .GetDeviceID;
         .[warning] "must have" [AndroidManifest.xml]:
            <uses-permission
android:name="android.permission.READ_PHONE_STATE"/>         
   jTextView:
      NEW property: // <<--- Thanks to Fatih!      
         FontFace;

   jEditText:
      NEW properties: // <<--- Thanks to Fatih!      
         TextTypeFace;
         FontFace;
         Editable; <<-A suggestion and request by rx3.fireproof
   jSpinner:
      NEW properties:   <<-A suggestion and request by rx3.fireproof
         FontSize;
          Count;
   jHttpClient:
      NEWS methods: <<-A suggestion and request by Ps   
         .SetAuthenticationUser(...);     
         .SetAuthenticationHost(...);
      NEW property:   
         AuthenticationMode [just basic... yet]

   jWebView:
      NEW property: // <<--- Thanks to Fatih!   
         ZoomControl;   
      NEW method: <<-A suggestion and request by Ps
         SetHttpAuthUsernamePassword(...);

   jListView: FIXs [radio group mode]
      LOST property:   
         HighLightSelectedItem;
         ::Please, no panic! When prompt "Read error" [Unknown
Property] just choice "Continue Loading"

Thanks!

P.S. [rx3:]

1. jSpinner: I added 3000 Items ... no problem!
2. jEditText: OnEnter [just OnExit ... OnDone ... OnGo ]

----------------------------------------------------------------------
ps · 2015-02-18 20:28

Thank's for update and thank's for SetHttpAuthUsernamePassword 

jHttpClient can be really hard to implement for real world situation
I'm trying work with https. And this don't work easy in Android
itself. Now I'm trying do something with okHttp
(http://square.github.io/okhttp/). Problem is with self signed cert or
with trusted cert but not supported with google.

Please look at TextHint property I requested. In Java code
this.setHint("This will be hint when edit box is empty") this is very
useful for search edi box and so on ...

----------------------------------------------------------------------
jmpessoa · 2015-02-19 00:47

OK!

   jEditText:
      NEW property:
         HintTextColor; <<-A suggestion and request by Ps

Done!

P.S. [About HttpClient]
       You can try pure FPC/FCL  library ... !

----------------------------------------------------------------------
rx3.fireproof · 2015-02-19 00:52

Hello Jmpessoa

Thanks for the update.
I used it in the Demo. New Demo upload on the link above.

I have a spinner does not work.
I put in new demo database with large fetching of data.
Database name "rx3char.db". The base is copied to data/data/ when you
first start.

Use in the AndroidModule2 is commented out in the procedure
«Add_size»  and «AndroidModule2JNIPrompt» .

To test it is necessary to disable rx3.db and connect rx3char.db.

For example:
When selecting item "ГОСТ 8239-89", app works. Count items = 17.
When selecting item "ГОСТ 26020-83", app crashes count items >100
When selecting "ASTM A 6/A 6M – 12»,  app crashes also count items
>200.

«rx3char.db» with strings, but in this case I think it is not
important.
Added DecimalSeparator:=','  for app to work.

Please see what is wrong I am doing.

Continue to develop Your module, there are some difficulties.
1. Z order does not work in the design. If the component should be at
the bottom, it should be put last.  For example background image.

Ok I will try it!

About order:
If you need jImageView to match all background form, then put it first
in the form!
But, if you need any component in bottom just configure
PosRelativeToParent = [rpBottom] ... do not need anchor

Abou "real" ... change/cast to "single" ... there is not "real"
compatible to android!

About  “maxtextlengh =300” .... changed! now maxtextlengh = -1
[default : no limited!!!]

Question 1:

Is there an easy way to create a simple android library (.so)?

Code: [Select]library MyLibrary;
{$mode objfpc}{$H+}

function Add(a, b: integer): integer;
begin
  Result := a + b;
end;

exports
  Add name 'Java_Adder_Add';

begin
end.

Code: [Select]package org.test.project1;

class Adder
{
  public native int Add(int a, int b);
  static
  {
    System.loadLibrary("mylibrary");
  }
}


QUestion 2:

How can we use the library from question 1 (.so without source code)
in a LazAndroidModule project?
 case A: called from java code
 case B: called from pascal code

You've had it in Question1 actually. Put the source in src directory,
under correct package directory.
case B:
Put the lib in libs/<arch: armeabi, x86, mips, etc.> directory, you
can call it from Pascal code in normal way to access dynamic library.

Hi Stephano, [and All!]

I tried to answer your questions! 
[yes, the Leledumbo pointed the right and direct way!]

Please, get a new revision: 

ref.  https://github.com/jmpessoa/lazandroidmodulewizard

Version 0.6 - rev. 18 - 22 February 2015 -

   ::Tutorial to Stephano Questions:

      1. Create a new "Lamw" project as usual [save all to ../jni]

      2. Add to ../src the new java class code [ex. jhelloadder.java]

      3. Go to [again] IDE->Project->New Project select [again] "JNI
Android Module" Project
                   and [again] Select the same project [form
workspace]

      4. But, NOW double click the added java class code
[jhelloadder.java]

      5. Ok

      6. Save all new project to ../jni [warning: keep the project
name [jhelloadder.lpr],
         but change the unit name :: ex. "unithelloadder.pas"]


      7. Yes, the new "jhelloadder.lpr" have the "drafts" code for all
native methods!

         function Add(PEnv: PJNIEnv; this: JObject; _a: JInt; _b:
JInt): JInt; cdecl;
         begin
             {your code....}
             {Result:= ;}
         end;

         function StringUpperCase(PEnv: PJNIEnv; this: JObject; _str:
JString): JString; cdecl;
         begin
             {your code....}
             {Result:= ;}
         end;

      8. Yes, you have a new form [datamodule]: You can put there any
"pure/fcl" TComponent descendant!
         [not LCL component, not Lamw component] --->> TODO: need more
test

      9. Go to [again] IDE->Tools->Android Module Wizard->New
jComponent [Create]

      10. Paste the "jhelloadder.java" into Tab "java" ...

                        WARNING: after paste, remove de word "public"
from class definition!
                        [TODO: need fix the parse ...]
                                          
      11. Read the content of Tab "help" ... [follow the
instructions!]

         Do not forget:

         //Please, you need insert:
            public java.lang.Object jHelloAdder_jCreate(long _Self) {
                    return (java.lang.Object)(new
jHelloAdder(this,_Self));
               }
         //to end of "public class Controls" in "Controls.java"

      12. Open "tfpandroidbridge_pack.lpk --> More -> Recompile Clean
-> Use -> Install !!
      13. Use Case 1: Pascal call Java :: drop the new component to
jForm [main app] and use it!
      14. Use case 2. Java call Java   :: declare and use it! ex.:

         jHelloAdder helloadder;
         helloadder = new jHelloAdder(controls, 1010);
//controsl=reference to main "controls" object :: 1010 = dummy
         Log.i("jHelloAdder_Add","Add(7,11)="+ helloadder.Add(7,11));

      15. Please,  see the new project demo ...   

   NEW! Demo AppAddSingleLibraryDemo1     [Eclipse Compatible
Project]   


Thank you!

PS. Yes,  I will try a more simple [solution] library [no form at
all!] just pure ".so"

----------------------------------------------------------------------
Stephano · 2015-02-22 20:25

I have read very quickly Leledumbo's and your replies, and will read
them more carefully and make tests tomorrow. But I guess your
suggestions rely on the fact that the source code of the 1st library
is available when it is not.

To make my case clearer, let's say somebody sends me a libcontrols1.so
(produced using lawm) and I want to use it either with lawm (or some
other tool). My question is how to use it with lawm and have:
a- the java code make the calls to libcontrols1.so
b- the pascal code make the calls to libcontrols1.so

----------------------------------------------------------------------
tuntnguyen · 2015-02-23 04:13

I have downloaded the lastest revision to reinstall
lazandroidwizardpack.lpk
I still get this problem:

D:\laztoapk\lazandroidmodulewizard\androidwizard_intf.pas(179,15)
Error: There is no method in an ancestor class to be overridden:
"TAndroidWidgetMediator.GetObjInspNodeImageIndex(TPersistent,var
LongInt);"

Code: [Select]..
public
    // needed by TAndroidWidget
    constructor Create(AOwner: TComponent); override;
    destructor Destroy; override;
    procedure InvalidateRect(Sender: TObject; ARect: TRect; Erase:
boolean);
    property AndroidForm: jForm read FAndroidForm;
  public
    procedure GetObjInspNodeImageIndex(APersistent: TPersistent; var
AIndex: integer); override;
  end; 

How to fix this?
I am using Lazarus 1.2.6 and FPC 2.6.4

Hello Jmpessoa

I updated arxdemo.

There are some problems.

1. The main problem

The demo works, but if you add in Androidmodule2 two jedittext, app
crashes.

It is possible to correct by moving the procedure «add_nd» from 
AndroidModule2JNIPrompt in a separate thread ( the weak point adding
in spinner).
Don't want to create a thread.
I temporarily used jtimer =>> jTimer1Timer.

I'm not a programmer, but this is some kind of conflict the execution
speed of the code. 

Probably need an event after AndroidModule2JNIPrompt, for example
onShow or onActivite or afteJNIPrompt.


2 jmagebtn properties ImageUpIndetifier and ImageDownIndetifier not
work.
For graphical buttons I used jimageview+jtimer. Looks decent, if you
don't know what is it made of.


3 jlistview.
If the property HighLightSelectedItemColor not equal colbrDefault,
there may be problems with the removal of the last items. If you
delete items twice  at the end of the list, the app crashes.

4 above z-order
Add a jbutton in AndroidModule2 and place it in the area jimageview3.
The button cannot be pressed, the button will be under jimageview3.
You can't change the Z-order when designing forms , only to remove
components and add in the correct order.



Have questions.

1. This code does not work.

stringlist:=Tstringlist.create;
……
stringlist.free;
……..
if stringlist<>nil then begin
stringlist.free;
end;

How to check whether there is object stringlist?

2. How to use code to disable speller (red line) in jedittext
(Androidmodule5 arxdemo).

Hi @rx3,

I  will try implement yours suggestions!

Thank you!

----------------------------------------------------------------------
jmpessoa · 2015-02-25 01:27

Hi @Stephano,

Quote...let's say somebody sends me a libcontrols1.so (produced using
lawm) and I want to use it either with lawm (or some other tool). My
question is how to use it with lawm ....

Quotea- the java code make the calls to libcontrols1.so
b- the pascal code make the calls to libcontrols1.so ...

After some tests, I can share/show my findings:

1. As case study [simplification!] I make use of a very simple
"libMyLib.so" 
[Ok, it was made by pure NDK using "C"]

You can get from here:
https://jmpessoa.opendrive.com/files?Ml83NzE5Mjk1NV95QmRpUw 

The produce project [.rar] is here:
https://jmpessoa.opendrive.com/files?Ml83NzE5MzU4OV9MTFZjMg

Why not a ".so" made by Lamw? Only because at the moment [as is] Lamw
can not do a very very "raw" .so  [TODO list!] --- but everything
written here works with a ".so"produced by Pascal/Lamw!

2. Here is the "MyLib.java" code:

Code: [Select]package jmpessoa.ndktest;

public class MyLib {

   static {
        System.loadLibrary("MyLib");
    }

    public native int add(int x, int y);
    public native String getHello();
}

And here is the JNI "C" export  signature : [by libMyLib.so]
Code: [Select]JNIEXPORT jint JNICALL
Java_jmpessoa_ndktest_MyLib_add(JNIEnv *, jobject, jint, jint);
JNIEXPORT jstring JNICALL Java_jmpessoa_ndktest_MyLib_getHello(JNIEnv
*, jobject);

And here is the JNI "Pascal/Lamw" equivalent exports signature:
Code: [Select]function Java_jmpessoa_ndktest_MyLib_add(PEnv: PJNIEnv;
this: JObject;  x:jInt, y:jInt): jInt;
function Java_jmpessoa_ndktest_MyLib_getHello(PEnv: PJNIEnv; this:
JObject): jString;

Yes, this method name format is mandatory for JNI
"Java_pagckagename_classname_methodname"

Question b [SOLVED!!!]: the Pascal/Lamw code can make calls to
"libMyLib.so" !!

b.1 - Prepare to Linker [-Fl]

In my system I  Copied the "libMyLib.so" to
C:\adt32\ndk10\platforms\android-13\arch-arm\usr\lib\

b.2 - Prepare to Apk

Copy "libMyLib.so"   to  "..\libs" yes, together with "libcontrols.so"

b.3 - Declare the library and methods in your Pascal/Lamw code:

Quoteconst NATIVE_LIB = 'libMyLib.so';

function Add(PEnv: PJNIEnv; this: jObject; x: jInt; y:jInt): jInt;
cdecl; external NATIVE_LIB name 'Java_jmpessoa_ndktest_MyLib_add';

function GetHello(PEnv: PJNIEnv; this: jObject): jString; cdecl;
external NATIVE_LIB name 'Java_jmpessoa_ndktest_MyLib_getHello';

b.3 - Use it!

Code: [Select]procedure TAndroidModule1.jButton1Click(Sender:
TObject);
var
  sum: integer;
  hello: string;
begin
   sum:= Add(gApp.Jni.jEnv,gApp.Jni.jThis,10,20);
   ShowMessage(IntTostr(sum));
  
   hello:= Get_pString( GetHello(gApp.Jni.jEnv,gApp.Jni.jThis) );
   ShowMessage(hello);

   //Get_pString <--> convert java string to pascal string   
end;

Yes!! Pascal/Lamw can use it!!

Considerations: in fact Pacal/Lamw no matter how the function
name/signature was "designate" [exports],  so we can use any ".so"
compiled to android/arm/x86 etc... even more complex made by Lamw!

Question a:  the java code make the calls to libMyLib.so

a.1 In the same/"natural" package [ no problem ....] just copy it to
"...\libs"    and use it!

Code: [Select]package jmpessoa.ndktest;

public class MainActivity extends Activity {

       //From JNI
       MyLib mylib = new MyLib();       
  
    String helloFromC = mylib.getHello();
    int sum = mylib.add(2,5);

    ...........................
}

a.2 In the "strange" package: NOT!!!

why? the original exported name JNI preface: "Java_jmpessoa_ndktest_" 
need match!

Code: [Select]package strange.test;

public class MyLib {

   static {
        System.loadLibrary("MyLib");
    }

    public native int add(int x, int y);
    public native String getHello();
}

Fail! Native method not found!
because: "Java_strange_test_MyLib_add"  and
"Java_strange_test_MyLib_getHello" was expected but
"Java_jmpessoa_ndktest_*" was found!

[workaround] You can force and design [your new project]  package
"preface.name" as expected, that is: "jmpessoa.ndktest"!

conclusion: native Pascal/Lamw can do! java? need a workaround...

Thank you!

@jmpessoa,
What do you mean by very very raw .so that Lawm cannot produce?
1- A pure Pascal library?
2- A pure Pascal library that makes jni calls?
3- A library that makes pascal code and jni calls and includes java
code (for overriding methods)?

----------------------------------------------------------------------
jmpessoa · 2015-02-27 21:53

@Stephano,

Nothing like that ....I want to say:

As is,  the  minimalistic libray code produced by Lamw include:

TCustomApplication
TDataModule

as posted in  February 22, 2015, 04:05:46 pm explication ....

When, in fact,  in some cases, minimalistic code like below, could be
enough [TODO list!]:  [basically to reuse and/or modularization]

Code: [Select]library jhelloadder;  //[by LazAndroidWizard: 2/22/2015
4:52:05]

{$mode delphi}

uses
  Classes, SysUtils, jni;

function Add(PEnv: PJNIEnv; this: JObject; _a: JInt; _b: JInt): JInt;
cdecl;
begin
  {your code....}
  Result:= _a + _b;
end;

function StringUpperCase(PEnv: PJNIEnv; this: JObject; _str: JString):
JString; cdecl;
var
  _jboolean: jBoolean;
  pascalStr: string;
begin
  {your code....}
  case _str = nil of
    True : pascalStr:= '';
    False: begin
          _jboolean := JNI_False;
           pascalStr:= string( 
PEnv^.GetStringUTFChars(PEnv,_str,_jboolean));
         end;
  end;
  Result:= PEnv^.NewStringUTF(PEnv, PChar(Uppercase(pascalStr)));  ;
end;

function JNI_OnLoad(VM: PJavaVM; reserved: pointer): JInt; cdecl;
var
 PEnv: PPointer;
begin
  PEnv:= nil;
  Result:= JNI_VERSION_1_6;
  (VM^).GetEnv(VM, @PEnv, Result);
end;

procedure JNI_OnUnload(VM: PJavaVM; reserved: pointer); cdecl;
begin
   //
end;

exports
  JNI_OnLoad name 'JNI_OnLoad',
  JNI_OnUnload name 'JNI_OnUnload',
  Add name 'Add',
  StringUpperCase name 'StringUpperCase';

begin
  //
end.   

At the moment to achieve this minimalistic code we need to strip the
Lamw generated code...
But, again: everything written there/previous    works with any ".so"
produced by Pascal/Lamw! Although they are more complex ...

This is a problem only with version Laz4android 1.5.

x.php/topic,21919.msg169959.html#msg169959
 greatly limit the imagination and of course spiner. 

I think a limit on the number of components on the form, is caused by
incorrect calculation of the form layout. But I'm not a programmer.

@Jmpessoa


I will show

Take my demo.

Upgrade code templates

In Androidmodule2 remove jspinner1 and jspinner2

Comment out code with jspinners.

Add seven jEditText for example below jTextView5  -  the application
works.

Add one more jEditText - the app crashes.

Delete the last two jEditText and add two JTextView - the app works.

Add one more JTextView- the app crashes.

Conclusion
On the form may be a limited number of visual components.
The number is determined by the component type.

This is the main problem for me


If a form contains jspinner, the number of components is reduced.


I think that the problem is the number of components and loading in
jspinner related .

But now for me is more important than the number of components on the
form.

Hello Jmpessoa  

There is a small problem with jEdittext.

If you touch, jEdittext in focus.
When the keyboard appears jEdittext moves above the keyboard.

If you press the BackButton, the keyboard disappears, jEdittext
retains the focus.

If touched again jEdittext, keyboard covers jEdittext (jEdittext is
already in focus).

Quote....When the keyboard appears jEdittext moves above the

Please, try:

Code: [Select] jEditText1.SetImeOptions(imeFlagNoFullScreen);

So,  IME will never go into full screen mode, and always leave some
space to display the application UI.

There are others possibilities:

TImeOptions = (imeFlagNoFullScreen,
                 imeActionNone,
                 imeActionGo,
                 imeActionSearch,

@m4u_hoahoctro,

To compile and (re)install a Lamw package you need a windows project
open in Lazarus IDE!

You can't compile and install a Lamw package if a cross-compile/Lamw
project is open!

from "install_tutorial_ant_users.txt" and
"install_tutorial_eclipse_users.txt":

but it appears 2 errors:
Missing styles. Is the correct theme chosen for this layout? and NOTE:
This project contains resource errors, so aapt did not succeed, which
can cause rendering failures. Fix resource problems first.

(Project -> Clean).

but there is still an error:

The demo folder has two folder: Ant and Eclipse..... if you choice
Eclipse folder you can see: many demos applications. For example: 
 ....\demos\Eclipse\AppBluetoothDemo1

If you open  "jni" folder you can see the  lazarus project
"controls.lpi".

Alternatively you can go to Lazaru IDE  --> "Project --> Open
Project"  and go to

"...\demos\Eclipse\AppBluetoothDemo1\jni" and open the "controls.lpi"

but you need modify "controls.lpi"  in two places according to your
system paths:

zxing is  barcode scan  liabry   for  ios  andriod ,windows .
it is a very Important  for app

----------------------------------------------------------------------
jmpessoa · 2015-04-14 03:58

@ liuzg2

Ok, I searched and found a trivial [and recommended] solution
but you need the ZXing App Installed  in your device [it is free!]

ref.  http://androidcookbook.com/Recipe.seam?recipeId=3324 

Yes, Lamw can use  ZXing to scan bar code for us! Follows a simple
code  demonstration:

1. Call ZXing App barcode scanner using jIntentManager:

Code: [Select]procedure TAndroidModule1.jButton1Click(Sender:
TObject);
begin

   
 jIntentManager1.SetAction('com.google.zxing.client.android.SCAN');

     jIntentManager1.PutExtraString('SCAN_MODE', 'PRODUCT_MODE'); 
 //Prod

     //or jIntentManager1.PutExtraString('SCAN_MODE',
'QR_CODE_MODE');   //QR
     //or jIntentManager1.PutExtraString('SCAN_FORMATS','CODE_39,CODE_
93,CODE_128,DATA_MATRIX,ITF'); //others
  
     //Call ZXing Barcode Scanner to scan for us:
     jIntentManager1.StartActivityForResult(0);      //user-defined
requestCode= 0

end;

2. And get the result here [jForm OnActivityRst event]:

Code: [Select]procedure
TAndroidModule1.AndroidModule1ActivityRst(Sender: TObject;
  requestCode, resultCode: Integer; jIntent: jObject);
begin
  if  requestCode =  0 then  //user-defined requestCode= 0
  begin
    if resultCode = -1 then  //ok
    begin

        ShowMessage('FORMAT: '+jIntentManager1.GetExtraString(jIntent,
'SCAN_RESULT_FORMAT'));
        ShowMessage('CONTENT:
'+jIntentManager1.GetExtraString(jIntent, 'SCAN_RESULT'));

    end else ShowMessage('Fail/cancel to scan....');
  end;
end;

Thank you!

----------------------------------------------------------------------
liuzg2 · 2015-04-15 00:31

1  yes  great  it works
but 

jIntentManager1.GetExtraString(jIntent, 'SCAN_RESULT')
result is null
jIntentManager1.GetExtraString(jIntent, 'SCAN_RESULT_FORMAT'));
result is null

and Eclipse [where "MainActivity" MUST be called "App"].... I do just

Hi All

I just uploaded a new app demo to show the bar code reading... 

AppIntentDemoZXing1 [Eclipse Compatible Project]

https://github.com/jmpessoa/lazandroidmodulewizard

Here is the basic code [improved!].

1. [Try] Call ZXing App barcode scanner using jIntentManager:

Code: [Select]procedure
TAndroidModule1.jListView1ClickCaptionItem(Sender: TObject;
  Item: integer; caption: string);
begin

   jIntentManager1.SetAction('com.google.zxing.client.android.SCAN');
   if  jIntentManager1.IsCallable(jIntentManager1.GetIntent()) then
   begin
       //ShowMessage('ZXing App is Installed!! ');

       case Item of
          0: jIntentManager1.PutExtraString('SCAN_MODE',
'PRODUCT_MODE');   //Prod
          1: jIntentManager1.PutExtraString('SCAN_MODE',
'QR_CODE_MODE');   //QR
          2: jIntentManager1.PutExtraString('SCAN_FORMATS',
'CODE_39,CODE_93,CODE_128,DATA_MATRIX,ITF'); //others
       end;

       //ZXing Barcode Scanner to scan for us
       jIntentManager1.StartActivityForResult(0);      //user-defined
requestCode= 0

   end
   else  //download ZXing
   begin
      ShowMessage('Try downloading   ZXing App ...');
      if not Self.IsWifiEnabled() then Self.SetWifiEnabled(True);
     
jIntentManager1.SetAction(jIntentManager1.GetActionViewAsString());
      //or jIntentManager1.SetAction('android.intent.action.VIEW');
      jIntentManager1.SetDataUri(jIntentManager1.ParseUri('market://se
arch?q=pname:'+'com.google.zxing.client.android'));
      jIntentManager1.StartActivity();
   end;
end; 

2.And get the result here [jForm OnActivityRst event]:

Code: [Select]procedure
TAndroidModule1.AndroidModule1ActivityRst(Sender: TObject;
  requestCode, resultCode: Integer; jIntent: jObject);
begin
  if  requestCode =  0 then  //user-defined requestCode= 0
  begin
    if resultCode = -1 then  //ok
    begin
        ShowMessage('FORMAT: '+jIntentManager1.GetExtraString(jIntent,
'SCAN_RESULT_FORMAT'));
        ShowMessage('CONTENT:
'+jIntentManager1.GetExtraString(jIntent, 'SCAN_RESULT'));
    end else ShowMessage('Fail/cancel to scan....');
  end;
end;

Thank to All!

how can i get itemindex (number of item clicked) same as function

@m4u_hoahoctro

Quote....how can i get itemindex (number of item clicked)....

In event "ClickCaptionItem"  or ClickItem [jListView]:

Code: [Select]procedure
TAndroidModule1.jListView1ClickCaptionItem(Sender: TObject; Item:

begin
       case Item of
          0: ............
          1: ...........
          2: ...........

There is too IsItemChecked(index: integer) when you have a checkbox or
radio button composing you item row;
Code: [Select]  if jListView1.IsItemChecked(1) then ....
  else ......

"dirInternalAppStorage" is the internal location where your App save
files....  so, "hello.txt"  need be a file created and saved by your
App... is that right?

horacio_ar · 2015-05-02 00:38

jmpessoa: your work is impressive! very good job!
I tried Delphi XE8, and it works... but produce extra big application.
I tried Lazarus with customdraw, and is usefull for some things, but
not native widgents. The edit control have some issues.
Then I tried AMW and got the best first impression!
Now the things I need to continue:
1) How to set the ActiveControl property to the form (the one that
will have the focus on start)?
2) How to set the TabOrder?
I have 2 jEditText controls on the form and 1 jButton. Pressing NEXT
on keyboard on the first control shoud activate the seccond one... For
the seccond one the keyboard should say Finish (or so) and on activate
this key should call the OnClic of the button. how to do this?
3) The 2nd jEditText control must accept only some characters. In this
case it should allow only HEX characters (0 to 9 and A to F)... I did
not found the way to do this... how can I do this?
4) I want to interact with a MS SQL Server. For this I fould jTds java
library. I tried to understand how to create the components for this,
but I was unable to find the approach? Any hint on this will be
appreciated.
Other option should be using SqlDB, but need the .so library and I was
unable to find it anyware.
Thats all for now.
Horacio

jmpessoa · 2015-05-02 02:39

@horacio_ar

1. You can try handle the event "OnJNIPrompt" from jForm

Code: [Select]procedure
TAndroidModule1.AndroidModule1JNIPrompt(Sender: TObject);
begin
    jEditText1.SetFocus;
end;

2. You can try handle the event "OnEnter" from jEditText
[enter  --->  "enter" or "done" or "next" or "go" ...]

Code: [Select]procedure TAndroidModule1.jEditText1Enter(Sender:
TObject);
begin
     jEditText2.SetFocus;
end;

3. jEditText has the property "InputTypeEx" but very limited yet [I
will try improve it!]

4. You can try "SQL Server"  via jHttpClient ... I do not know about
sql client in android...

Thank you!

Hello Jmpessoa


How to destroy the form (Androidmodule) and to free the memory. In my
program are 23 forms (Androidmodule). If everything is created, the
application is in memory of about 120 mb.

Now I am using a form with «actSplash».

I tried to use «self.finish». The form is destroyed, but not created
again.

If it possible, show an example code.



With Respect

Hello Jmpessoa

In the new version introduces the ability to destroy the form and free
the memory?

The Jspinner does not fully work. 

Impossible to put on the form the required number of components

My main problem is not solved.

@rx3.fireproof

I think that all these problems are related to memory management ....

What about your "assets"? What about images files sizes?

example: In my tests jSpinner is OK for a huge entry!

OK, I'll see what I can improve!

Thank you!

@Jmpessoa

Now made form (actsplah) with 6 jspinners and 30 jimageviews with
images from assets and drawable (halfpast). 
In each jspinner  added on 10000 items. Everything works.

I have something wrong with the layout. Try to understand.

I made  test new project.

May be an error while upgrate code template with old version LAMN?

Quote...May be an error while upgrade code template with old version
LAMW?

Yes, may be.....

You can try:

1. Upgrade Code templates: [*.lpr] and [*.java]

2. Run --> Clean up and Build

When prompt "Read error" [Unknown Property] just choice:  "Continue
Loading" !!
[Now simulate any property change in component, i.e., tag = 1  and
save the project]

3. Run --> [Lamw] Build Apk and Run      //<<---------- connect your
device [usb] !

Thank you!

Hello Jmpessoa

My problem is not in the jspinner.  The problem in the jSqliteCursor.

This code works in  the procedure  AndroidModule1JNIPrompt  if
rowCount<=5.


var
i, rowCount:integer;

jSqliteDataAccess1.Select('select * from mytable');

rowCount := jSqliteDataAccess1.Cursor.GetRowCount;

for i := 0 to rowCount - 1 do begin
      jSqliteDataAccess1.Cursor.MoveToPosition(i);
    //  jspinner1.Add(jSqliteDataAccess1.Cursor.GetValueAsString(2));
end;       



In other procedures is work  if rowCount near 100-150.

How to make that the code is worked?



With Respect

why my build apk can not run?codes no problem,compile ok,build apk
ok,but run app does not show any component,only a blank window.

Hi,

Is there a way to get position and size of a component? Right now
Left/Top/Width/Height properties only return value from fields and not
the real position of components in most cases.

I also tried to add component to form/custom dialog using code but
failed. Can anyone show me a working example so I can study?

The last thing is we can change color of a button, but then we lost
"touch effect" when touching it. Could this behavior be changed in
future releases?

Thanks in advance.

Solution:

Put a jPanel and  change its Backgroundcolor,  then configure [after
put the button over it!]:
    
      LayoutParamWidth = lpWrapContent
      LayoutParamHeight = lpWrapContent

Now put a jButton over jPanel and configure:

      BackgroundColor = colbrDefault
      LayoutParamWidth = some value
      LayoutParamHeight = lpWrapContent
      PosRelativeToParent = [rpCenterInParent]

Thank you!

Ops I forgot button itself is transparent by default so we just need
to change color of component behind it, thanks!

no special .... but if your file is in the sdcard you will need:

<uses-permission
android:name="android.permission.READ_EXTERNAL_STORAGE"/>

NOTE: Lamw has jMediaPlayer component e a demo "AppTryCode2":

Code? just try:

Code: [Select]     jMediaPlayer1.SetDataSource('pipershut2.mp3'); 
//from  .../assets...
     jMediaPlayer1.Prepare();
     jMediaPlayer1.Start();

Thank you!

@greenzyzyzy,

You need know/discovery what is the path to your device sdcard ... 
just "/sdcard" can not work for all devices .... in java:
Environment.getExternalStorageDirectory()

@m4u_hoahoctro

1. Well, when you update your Lamw some code can not work....
because some component property was lost but:
no panic! When prompt "Read error" [Unknown Property] just choice
"Continue Loading"

2. At the moment Lamw Author "A.S." is doing a hard [and nice] work to
improve form designer, so old project can have some layout impact [but
just in design time!]

3. If you problem is just with jTextView17/jTextView18 , you can try:

jTextView17
Anchor = jTextView13

jTextView18
Anchor = jTextView17
PosRelativeToAnchor = [raToRightOf,raAlignBaseline]

@greenzyzyzy,
In fact, with this pure [and hard!] JNI approach to access java
objects the things get very very complicated to Pascal [and Lazarus]
...

@jmpessoa,

Now I am having a trouble with jtextview and jimage, some jtextviews
and jimages are dissappeared when I run apk file. I try to fix many
times but it doesn't change

Download my project, build and run it, you will see jtextviews
(7,8,11,12,15,16) don't appear ( form2), and jimage (form3) doesn't
show its image, althought I choosed layout for them and type Image
index correctly 

My friend said this is a bug, Is he true ?

2. At the moment Lamw Author "A.S." is doing a hard [and nice] work to
improve form designer, so old project can have some layout impact [but
just in design time!]

3. If you problem is just with jTextView17/jTextView18 , you can try:

jTextView17
Anchor = jTextView13

jTextView18
Anchor = jTextView17
PosRelativeToAnchor = [raToRightOf,raAlignBaseline]

@greenzyzyzy,
In fact, with this pure [and hard!] JNI approach to access java
objects the things get very very complicated to Pascal [and Lazarus]
...

thank you for reply,media_create( ) procedure run pass.
but next procedure still can not run.

end;

procedure Start();
begin
 javaEnvRef^^.CallVoidMethod(javaEnvRef,
jmediaplayer_jobject,start_id);
end;

procedure Release();
begin
 javaEnvRef^^.CallVoidMethod(javaEnvRef,

run these codes still halt.

does laz4android threads can not support TBitmap?
just use beginthread or tthread class. it seems only support TBitmap
some method
juse like loadfromstream,savetostream,loadfromfile,savetofile.
but use TBitmap.canvas or TBitmap.width,TBitmap.height
property,application exit immediately.
no idea to use TBitmap in thread perfect?

Hello Jmpessoa

The jScrollView does not work fully. If I send the unit and form with
drawable by email, You can see why it doesn't work. If you do not use
the jScrollView, it works, but I need scrolling.

On 0.6.23 this form is worked as actsplash.

Hi All

There is an updated "Lamw/Lazaru Android Module Wizard"   revision!

ref. https://github.com/jmpessoa/lazandroidmodulewizard

Version 0.6 - rev. 26 - 21 May 2015 -

   NEW! 
      jTCPSocketClient component

   FIXED! 
      jHorizontalScrollView component
   NEW! 
      Demo AppHorizontalScrollViewDemo1 [Eclipse Compatible Project]
      Demo AppTCPClientDemo1 [Eclipse Compatible Project]

Thanks to All!

PS.

@rx3.fireproof,  the "AppHorizontalScrollViewDemo1" is too a
jScrollView demo!

and it is working!!!

Possible causes of your problem:

1. Old revision, before the bug fixed [18, 2015, 08]!
2. Property "ScrollSize" is smal
3. Visual designer trick: After put your jScrollView content, as the
last action,  you need set
the appropriate "LayoutParamHeight" property [by designer!].

----------------------------------------------------------------------
rx3.fireproof · 2015-05-22 17:48

@Jmpessoa

Non-working example.

https://yadi.sk/d/ppVq7KGdgp27G

It will work:

- If I remove any one jeditortext or jtextview;

- If I will set the property fontsize to zero for all jeditortext and
jtextview;

- I will not change the  property text for all jeditortext and
jtextview in JNIPrompt procedure.


In all other cases, the application does not start.

Please find the error.

Sorry, but for me now jScrollView in 06.26 does not work.

I tried to make my own example here using jShellCommand and nothing.
The application builds and installs all right, but when it tries to
run, a white screen appears and a warning from android, saying that
the application has stopped working, just remove this component of the
application that it works right, does anyone could tell me why this
happens?

I added to the archive working app.

Folder  "it_works_1"  with   property fontsize=0.

There is a tutorial about string array [and others...]: "MyHello.pas"

Demo: jMyHello component and app "AppTryCode1"

Minor diference:

We use "And_jni.pas" not "jni.pas", so we write:

"Env^.NewStringUTF(javaEnvRef, 'lazarus-ide');"

not   "Env^^NewStringUTF(javaEnvRef, 'lazarus-ide');"

java.lang.NoSuchMethodError: no method with name='Get'
signature='(Ljava/lang/String;)V' in class
Lcom/suevoz/hello/jHttpClient;

consider that the code is just the same that was working fine with
rev. 27, with the only difference that now I'm using
jHttpClient1ContentResult for retrieving the result of the Http
request.

Any idea?

with respect

I have some errors when compiling project:

@m4u_hoahoctro

@renabor

Yes, we did dramatic changes, sorry!

Please, you can learn the new components design/behaviour in the
Demos:  AppAsyncTaskDemo1 and AppHttpClientDemo1  !!!

1. jAsyncTask lost property "OnAsyncEvent" but no panic!
when prompt "Read error" [Unknown Property] just choice "Continue
Loading"!

Now copy the old code to matching/equivalent news events:
           OnDoInBackground
            OnProgressUpdate
            OnPreExecute
            OnPostExecute

2. jHttpClient: now "runInBackground/asynctask" have build in 
support! You do not  need more use jAsyncTask component to run it "in
background" !

ok, you will need handle the new event "ContentResult" to get content
result and
"get" now is a procedure [not a function] ... so, no more result!

Again, sorry ...

but, the changes was for more elegance and effective solution! 

Thanks to All!

browser and get url of site, so
how to do that ?

   if copyOk then
      jBluetooth1.SendFile(Self.GetEnvironmentDirectoryPath(dirDownloa

end;                            
After press button, my app closes and show notification: The

I am thinking about lamw no longer supports bluetooth connection on
andr 2.3  although If i use jsharefile, it still can work

@m4u_hoahoctro: the bluetooth components are partially functional, if
you see this
https://github.com/jmpessoa/lazandroidmodulewizard/issues/19, you will
know what I'm talking about. Right now, I'm experimenting with the
components, to see if I can implement these functionalities, but I'm
not making promises that they will work, or be reliable, I can only
promise that I will try to make it happens.

P.S.: I tried using on the APIs 15, 16, 17, 19 and 22, and I didn't
see what you've described.

I created a browser from your demo (Demo1-Webcontrol ), and when I
press button to navigate google.com ( or another link), webpage not
available ( I tested on virtual and real device, but result same as )

compiler also show error: not defind 'self.updatelayout', commands
about self.* still work if I don't use jwebview

this is project:

@jmpessoa, I haven't had any knowledges about web programming yet, so
although I tried to read your examples to write an web application,
but it seems not be easy 

if you have free time, would you mind helping me write an web
application that can read text data on a website ( example: read this
text and save to string from my site here:
http://cartoonforyou.forumvi.com/h1-page)

I also have some problems with jwebview as I replied above

thanks much

Well, I tried to do by myself, and failed miserably. I don't know the
why, I used code that worked on other application and nothing. Every
time I tested the new component with the modified functionalities, the
application didn't even start properly. For now, I'm gonna put this on
pause, but I will return to it briefly.

Hi @jmpessoa,

I have a problem with the Id of the objects.
Any new object inserted in a form get an Id of 0, with the conseguence
that you can imagine. Is it possible to automate the generation of a
unique Id for the newly created object?
I use Lazarus Ide under linux.

Which is the correct way to work with jHttpClient authentication, I
have tried this code but without positiv results:

      jHttpClient1.SetAuthenticationHost('http://192.168.1.16',80);
      jHttpClient1.SetAuthenticationUser('username', 'password');
      jHttpClient1.AuthenticationMode:=autBasic;
      jHttpClient1.Get('http://192.168.1.16');

and so, what is wrong?
Can you extend the jHttpClient Class implementing the UPDATE and
DELETE methods?

Another question about menu.
I have many Forms in my app and I need different menu in each form,
how can I achieve this result?
I use intensely jSqlLite and jHttpClient in any form of my app but I'm
unable to share the first instance so I recreate it in every new form.
Is there a way to improve it?
Can you suggest me a method to access Contacts for reading and writing
them?

thank you very much!

Finally I got authentication working!

Changing Controls.java:

Code: [Select]in class AsyncHttpClientPostNameValueData

after
                    HttpPost httppost = new HttpPost(_stringUrl);
adding this code:
                    if (mAuthenticationMode != 0) {
                            String _credentials = mUSERNAME + ":" +
mPASSWORD;
                            String _base64EncodedCredentials =
Base64.encodeToString(_credentials.getBytes(), Base64.NO_WRAP);
                            httppost.addHeader("Authorization", "Basic
" + _base64EncodedCredentials);
                    }

Code: [Select]in class AsyncHttpClientGet
after:
                    HttpGet httpget = new HttpGet(stringUrl[0]);
adding this code:
                    if (mAuthenticationMode != 0) {
                            String _credentials = mUSERNAME + ":" +
mPASSWORD;
                            String _base64EncodedCredentials =
Base64.encodeToString(_credentials.getBytes(), Base64.NO_WRAP);

Yes, that demo. I guess I build my FPC wrong because I recently played
with raspberrypi which uses hard float. I'll try to rebuild.

Thank you very much @jmpessoa, for code and cite!

I think something where wrong in the last revision that give me many
problems and errors. I use rev. 29 once again.
The main problem reside in impossibility to upgrade Code Templates
(Lazarus is unable to find Project file), and    throughout compiling
report many Access Violation errors.

And now some suggestions, requests and bugs:
Add the OnBack Event In jCustomDialog
The function JNIPrompt is not fired when a form is reactivated trough
a Back in a second form, solution could be to add an OnComingBack
event to jForm, or firing JNIPrompt event on coming back. At this time
data displayed cannot be refreshed in automatic on coming back to
first form
The jContextMenu cannot open a form
When a jContextMenu is linked to a jListView would very helpful that
the Caption of the Item clicked where accessible or passed. My need is
to edit or delete the record associated with the item clicked
jListView is lacking in configurability in order to display many
columns of data. What do you think about adding Columns or  something
like Tab to jListView?
Add an onClick event to jEditText, to make it possible, i.e., to open
in automatic a jDatePickerDialog
Add an itxCurrency mask for jEditText that admits dot and comma with
numbers together, or add dot and comma to itxNumber

Best regards and thanks for all

@jmpessoa, I get the attached image (that "read error" dialog)

It's not a problem (I'm closing the IDE after all), but it's annoying.

Leledumbo · 2015-06-19 17:48

One more thing, Lazarus freezes when I use Run->[Lamw] Build apk and
run. It freezes when running adb with no emulator/real device running,
my guess is that the external tool is not executed asynchronously.
Tools that I add to Configure External Tools seem to execute
asynchronously, though. Very weird.

----------------------------------------------------------------------
A.S. · 2015-06-19 19:05

Leledumbo, Run->[Lamw] Build apk and run uses external tools for
building/installing/running purposes. But it also determines connected
devices, and this check is not asynchronous.

Last request is partially resolved modifying in Controls.java (line
1436) :
Code: [Select]        if(str.equals("NUMBER")) {
           
this.setInputType(android.text.InputType.TYPE_CLASS_NUMBER);
        }
with
        if(str.equals("NUMBER")) {
            this.setInputType(InputType.TYPE_CLASS_NUMBER|
InputType.TYPE_NUMBER_FLAG_DECIMAL|
                     InputType.TYPE_NUMBER_FLAG_SIGNED);
       }

that permits input of numbers [0..9], a minus sign prepended and a
singular punctuation sign (only point, not comma)

Best regards

For my purpose I need the Id of last inserted row, but my effort are
unsuccessful.

I tried to add this method in Controls.java, related to class
jSqliteCursor:
Code: [Select]public long GetLastId() {
                if (this.cursor != null) {
                        int index = 0;
                        index = this.cursor.getColumnIndex("ROWID");
                        this.MoveToLast();
                        return this.GetValueAsLong(index);
        }
        else{
                return -1;
        }
}

this in Laz_and_controls:
Code: [Select]function jSqliteCursor.GetLastId: integer;
begin
   if not FInitialized  then Exit;
   Result:= integer(jSqliteCursor_GetLastId(FjEnv, FjObject ));
end;     

and this in And_jni_Bridge:
Code: [Select]Function jSqliteCursor_GetLastId(env:PJNIEnv; 
SqliteCursor: jObject): integer;
var
 _jMethod : jMethodID = nil;
 cls: jClass;
begin
 cls := env^.GetObjectClass(env, SqliteCursor);
  _jMethod:= env^.GetMethodID(env, cls, 'GetLastId', '()I');
 Result := integer(env^.CallLongMethod(env,SqliteCursor,_jMethod));
 env^.DeleteLocalRef(env, cls);
end;

and the log report:

I/dalvikvm( 4112): java.lang.NoSuchMethodError: no method with
name='GetLastId' signature='()I' in class
Lcom/suevoz/borsa/jSqliteCursor;

so, where is the error? Can you help me?

thank you!

OK, java/JNI 'long' signature is "J", then

Code: [Select] _jMethod:= env^.GetMethodID(env, cls, 'GetLastId',
'()I');

change to:

Code: [Select] _jMethod:= env^.GetMethodID(env, cls, 'GetLastId',
'()J');

Thanks to All and special thanks to @renabor !!

Thank you very much for all!

I've tried improvements and are all precious!
jContactManager is a must, although I have not tried it so much, I'm
working on another project now.

the OnBackKeyPressed in CustomDialog property is great, but break the
propagation of Event for soft backkey and del key, here an amended
version that handle both soft and hard backkey press:
Code: [Select]line ~ 10069 in Controls.java

mDialog.setOnKeyListener(new Dialog.OnKeyListener() {
@Override
  public  boolean onKey(DialogInterface arg0, int keyCode, KeyEvent
event) {
     if (event.getAction() == KeyEvent.ACTION_UP) {
        if (keyCode == KeyEvent.KEYCODE_BACK) {
             controls.pOnCustomDialogBackKeyPressed(pascalObj,
mTitle);
             if (mDialog != null) mDialog.dismiss();
             return false;
        } else if (keyCode == KeyEvent.KEYCODE_ENTER) {
            InputMethodManager imm = (InputMethodManager)
controls.activity.getSystemService(Context.INPUT_METHOD_SERVICE);
            imm.hideSoftInputFromWindow(getWindowToken(), 0);
            controls.pOnEnter(pascalObj);
            return true;
        }
     }
     return false;
   }
});

Finally I've found a solution for my problem in obtaining the item
index clicked out of jListView, here the code that add a listener to
OnItemLongClick Event and add the property ItemIndex to jListView:
Code: [Select]----- in  Laz_And_Controls.pas
line 1040
    function GetItemIndex: integer;
line 1083
    property ItemIndex: integer read GetItemIndex;
line 5120
    function jListView.GetItemIndex: integer;
    begin
      Result:= Self.Items.Count;
      if FInitialized then
        Result:= jListView_GetItemIndex(FjEnv, FjObject );
    end;

----- in  And_jni_Bridge.pas
line 485
  function jListView_GetItemIndex(env:PJNIEnv; ListView : jObject):
integer;
line 3915
  function jListView_GetItemIndex(env:PJNIEnv;  ListView : jObject):
integer;
  var
    _jMethod : jMethodID = nil;
    cls: jClass;
  begin
    cls := env^.GetObjectClass(env, ListView);
    _jMethod:= env^.GetMethodID(env, cls, 'GetItemIndex', '()I');
    Result:= env^.CallIntMethod(env,ListView,_jMethod);
    env^.DeleteLocalRef(env, cls);
  end;

------- in Controls.java
line 2785
  int itemIndex = -1;
line ~ 2887 
  itemIndex = position;
line ~ 2892
  onItemLongClickListener = new OnItemLongClickListener() {
    public boolean onItemLongClick(AdapterView<?> parent, View v, int
position, long id) {
      itemIndex = position;
      return false;
    }
  };
setOnItemLongClickListener(onItemLongClickListener);
line 2949
  public int GetItemIndex() {
    return itemIndex;
  }

Now I'm in trouble with jListView adapter, I'm trying to adapt this
example

http://www.codelearn.org/android-tutorial/android-listview

any idea is really appreciated

Hello Jmpessoa


There are two issues for new version.

1.What to use instead «gapp.BaseIndex»?
2. How to disable OnJNIPrompt event,   when a form is reactivated
trough a Backkeypressed?

With Respect

rx3.fireproof


With the new changes, nothing works. I'm back on 06.28

----------------------------------------------------------------------
jmpessoa · 2015-07-08 17:03

@rx3.fireproof

Please, wait .... I will try a solution  [today!] !

Thank you!

Edited:

Quote2. How to disable OnJNIPrompt event,   when a form is reactivated
trough a Backkeypressed?

solution: Added jForm property [boolean] PromptOnBackKey ... just do:

 .PromptOnBackKey := False;

Edited:

Quote1.What to use instead «gapp.BaseIndex»?

solution: Added jForm property [boolean] TryBacktrackOnClose ... just
do:

 .TryBacktrackOnClose:= True   for all forms in the stack ...

example:

1. AndroidModule1 ["actMain"]  open form2:

Code: [Select]  if(AndroidModule2 = nil) then
  begin
    gApp.CreateForm(TAndroidModule2, AndroidModule2);
    AndroidModule2.PromptOnBackKey:= False;
    AndroidModule2.TryBacktrackOnClose:= True;
    AndroidModule2.Init(gApp);
  end
  else
  begin
    AndroidModule2.Show;
  end;

2. AndroidModule2 ["actRecyclable"]  open form3:

Code: [Select]  if(AndroidModule3 = nil) then
  begin
    gApp.CreateForm(TAndroidModule3, AndroidModule3);
    AndroidModule3.PromptOnBackKey:= False;
    AndroidModule3.TryBacktrackOnClose:= True;
    AndroidModule3.Init(gApp);
  end
  else
  begin
    AndroidModule3.Show;
  end;

3. AndroidModule3 ["actRecyclable"]  open form4:

Code: [Select]  if(AndroidModule3 = nil) then
  begin
    gApp.CreateForm(TAndroidModule4, AndroidModule4);
    AndroidModule4.PromptOnBackKey:= False;
    AndroidModule4.TryBacktrackOnClose:= True;
    AndroidModule4.Init(gApp);
  end
  else
  begin
    AndroidModule4.Show;
  end;

Now if  you close form4 then all [3 and 2]   forms [actRecyclable] 
will close too!

Hello Jmpessoa

Disable OnJNIPrompt event works. Thank you.

On the first question about the «gapp.BaseIndex».

I have a more complex application logic.

As an example of.

From the form 1 you can create the form 2 or the form 3.
From  the form 2 or the form 3 you can create the form 4.
From the form 4 you can create the form 5.
The Form 5 can be created from the Form 1.

I made a working example on version 06.28 by reference
https://yadi.sk/d/YyEGt-gUhmWuQ

How to make this example on 06.32 version without «gapp.BaseIndex» I
don't understand.

In a real application I have a 27 forms. The data transmitted between
them by global records with many fields (string,  boolean and double).


With Respect

rx3.fireproof

----------------------------------------------------------------------
jmpessoa · 2015-07-09 18:30

Hello rx3.fireproof!

Try:

//gapp.BaseIndex

What happens if you comment this line? 

The form now know your [own] base... so, if you close it, you will
return to the form where it was created [or "showed" :edited after bug
fixed !]! 

But you can try return to "main" form using the new property
"TryBacktrackOnClose:= True"
in all chain ...the process will stop [before main] if some form [in
the way] was not set "TryBacktrackOnClose:= True"


The ideia is not have code like this [try comment this lines too!]:

Code: [Select] form_index_0_level:=-1;
  form_index_1_level:=-1;
  form_index_2_level:=-1;
  form_index:=-1;

the logic must be "controled" by framework!

----------------------------------------------------------------------
rx3.fireproof · 2015-07-09 19:14

@ Jmpessoa

If the chain one - control by framework .

What if three chains.
Form5 already exists.

In each chain there is potentially private data.

To destroy the form5 is impossible. I have not found a way to destroy
the form5 (form2, form3, form4...) and free the memory. So I use the
index for forms.

Please show how to use  "control by framework"  in the "Sample" (three
chains).  I will study and implement in my project.

Now sample is stable and has no bugs (only takes memory - sorry) . 
I'm not a programmer, what's inside the user is not interested.


With Respect
rx3.fireproof

----------------------------------------------------------------------
jmpessoa · 2015-07-09 19:40

Ok.  I am just doing you example:

QuoteFrom the form 1 you can create the form 2 or the form 3.
From  the form 2 or the form 3 you can create the form 4.
From the form 4 you can create the form 5.
The Form 5 can be created from the Form 1.

 ... some minutes ...

Ok I found a bug! Please fix here:    [<< ----   rx3!]

"androidwidget.pas"

Code: [Select]Procedure jForm.Show;
begin
  if not FInitialized then Exit;
  if FVisible then Exit;
  FormState := fsFormWork;
  FVisible:= True;

  FormBaseIndex:= gApp.TopIndex; // << ----   rx3!

  gApp.TopIndex:= Self.FormIndex;
  jForm_Show2(FjEnv,FjObject,FAnimation.In_);
  if Assigned(FOnJNIPrompt) then FOnJNIPrompt(Self);    //*****
end;

Now it is OK to all chains!

my code:

A little question regarding jHTTPClient: is it stateful or stateless?
I mean, can I use it to simulate a browsing session? I want to create
some kind of web crawler, so I need to go to certain page, do login,
save cookie, then browse the login-protected pages. Save cookie is be
the key, if it can, then I think it's possible to do what I want.

----------------------------------------------------------------------
jmpessoa · 2015-07-10 13:39

@Leledumbo,

At the moment  jHTTPClient is stateless ... supporting Get and Post
[name=value] data
and basic authentication....

OK, I will try implement cookies!

Thank you!

@ Jmpessoa

Everything works. Thank you.

There is a small question for the continuation of this theme on the
chains.

How to use code to determine  what the form will active when  press
the back button? Is this possible?

With Respect

jmpessoa · 2015-07-10 22:41

Yes!

Code: [Select]procedure TAndroidModule5.jButton1Click(Sender:
TObject);
var
   baseform: jForm;
begin
  baseform:= jForm(gApp.Forms.Stack[Self.FormBaseIndex].Form);
  ShowMessage(baseform.Name);
  ShowMessage(IntToStr(baseform.Tag));
end;

Hi jmpessoa, thanks very for your example 

But I haven't even seen this code before

Code: [Select]FImageBitmap:= Get_jObjGlobalRef(FImageBitmap);       
and
Code: [Select]Delete_jGlobalRef(FImageBitmap);   
Which reference page I can find more "strange commands" same as above 

With application run on PC, we can get position of mouse cursor, so on
android, when user touch on screen,how we can get position touched ?

@m4u_hoahoctro

1. we can not change GUI controls inside "AsyncTask OnDoInBackground":

Code: [Select]procedure
TAndroidModule1.jAsyncTask1DoInBackground(Sender: TObject;
  progress: integer; out keepInBackground: boolean);
begin  
    .....
    FImageBitmap:=
jImageFileManager1.LoadFromURL('http://miftyisbored.com/wp-
content/uploads/2013/07/nature-sound-spa-app.png');
//'http://i.imgur.com/n2lQnkI.png
    FImageBitmap:= Get_jObjGlobalRef(FImageBitmap);
    .....
end;

so, we need save  [jObject] "FImageBitmap" get from the Internet to
set "jImageView" in other code place ... but
JNI/Java Native Interface forget the [jObject] "FImageBitmap"
reference as soon as procedure "end;"

The solution is JNI "Get_jObjGlobalRef"  from "androidwidget.pas"

2. OnTouch is  implemented [at the moment] at least in "jView" and
"jSurfaceView"

code example:

Code: [Select]procedure TAndroidModule1.jView1TouchDown(Sender:
TObject; Touch: TMouch);
begin
   ShowMessage('Touch: X='+ FloatToStr(Touch.Pt.X) + '
Y='+FloatToStr(Touch.Pt.Y) );
end;

or

Code: [Select]procedure TAndroidModule1.jSurfaceView1TouchDown(Sender:
TObject; Touch: TMouch);
begin
   ShowMessage('Touch: X='+ FloatToStr(Touch.Pt.X) + '
Y='+FloatToStr(Touch.Pt.Y) );
end;


@rx3.fireproof

Yes, font size [behavior] changed! ...  sorry.... maybe, you need
increased it...

[we were having a lot of problems with "jListView" item font size]

EDITED: fontsize = 0 --> default  size!

Can we implement download file function  to phone ?
And about loading video + mp3 file with jmediaplayer and jsurfaceview
: Video and mp3 ( from links on internet ) are downloaded to phone
cache first and then played or loading and playing at the same time ?

thanks

To increase the size impossible. Problems with design time and
emulator.

----------------------------------------------------------------------
rx3.fireproof · 2015-07-12 13:28

If the fontsize=0.

The visual size of the font on device for jtextview less than for the
jedittext.

The font size is smaller than necessary.

Use a Lawn impossible. Please return the good fontsize.

Yes,  this is default for android.... try  increase only jtextview
font ....

Ok, I will do a patch to configure "old" mode ... please,  wait some
minutes ..

Thank you!

Edited: Done! go to github!

You can use new "SetChangeFontSizeByComplexUnitPixel(False)"  to get
the old
behaviour/mode!  [jtextview and jEditTex]

maybe you will need do "Lazarus IDE --> Run --> Clean up and Build" 
...

Added method "SetChangeFontSizeByComplexUnitPixel"
to jListView,  jButton,  jRadioButton,  jCheckBox,  jSpinner, 
jGridView,  jDigitalClock

default = True !

so, you need: SetChangeFontSizeByComplexUnitPixel(False)

FontSizeByComplexUnitPixel only works for  jListView,  jSpinner on

For jtextview and jEditTex not working.
SetChangeFontSizeByComplexUnitPixel(False)  not working to.

For jtextview  SetChangeFontSizeByComplexUnitPixel is absent.

ok!
Sorry for taking a long time. This is an embedded http server fpweb
app on port 8080 (install weblaz to compile on lazarus), you can just
run it from terminal then type http://localhost:8080<request> in the
address bar. Valid requests are: /cookie/set & cookie/get. Cookie
expires 1 minute after set. Note that the expiration time is in GMT so
your browser might wrongly interpret it if the timezone is not the
same.

To validate:
/cookie/get -> Cookie get:
/cookie/set -> Cookie set: somevalue
/cookie/get -> Cookie get: somevalue
wait for 1 minute
/cookie/get -> Cookie get:

Hello @jmpessoa!

I have found 2 bug, first regards ShowCustomMessage, that is declared
overload but different:

Code: [Select]procedure ShowCustomMessage(_layout: jObject; _gravity:
integer; _lenghTimeSecond: integer); overload;    
should be:
procedure ShowCustomMessage(_layout: jObject; _gravity: TGravity;
_lenghTimeSecond: integer); overload; 

the last is related to jListView and ItemIndex.
You have removed all Events related to ClickCaption, but in source
more and more reference to Caption are creating to me many problems.
Items in my ListView are complex, so in my application Caption isn't a
string and I can't get ItemIndex!
I suppose that all reference to Caption in all functions related to
Click Event are useless and can safely be removed.

I hope you can help me
best regards

----------------------------------------------------------------------
jmpessoa · 2015-07-16 00:46

Hello @renabor!


1. Ok,  ShowCustomMessage fixed! Thank you!

2.
Quote...so in my application Caption isn't a string and I can't get
ItemIndex

Code: [Select]  jListView = class(jVisualControl)
  private
      FOnClickItem  : TOnClickCaptionItem;
      .....

Here is the  "new" OnClickItem  signature:   [we stayed with the old
"OnClickCaptionItem" signature ]

Code: [Select]TOnClickCaptionItem= Procedure(Sender: TObject;
itemIndex: integer; itemCaption: string) of object;


Here the generated code:

Code: [Select]procedure TAndroidModule1.jListView1ClickItem(Sender:
TObject; itemIndex: integer; itemCaption: string);
begin
   
end;


Mybe your need update "OnClickItem " generated code ... [or, maybe, I
did not understand your problem ....]

EDITED: or "Click" is not fired?

EDITED: Please, change jListView [Controls.java] :

Code: [Select]controls.pOnClickCaptionItem(PasObj, (int)position ,
alist.get((int)position).label);

change to:

Code: [Select]controls.pOnClickCaptionItem(PasObj, (int)id ,
alist.get((int)id).label);

 (int)position changed to  (int)id

[solved?]

//      public  native void pOnListViewLongClickCaptionItem(long
pasobj, int position, String caption);
        public  native void pOnListViewLongClickItem(long pasobj, int

I use an Adapter and a List not standard:

      if(this.getAdapter() != optitListAdapter ) { 
this.setAdapter(optitListAdapter); }
      optitListAdapter.notifyDataSetChanged();

and therefore I must test if alist is empty or not.
I have removed all reference to Caption but can't resolve this error:

@renabor

1. About signature with "caption" or without "caption"....

I just do [now!] a minor change in  jListItemRow [Controls.java] 
[revision 34.2]

set
Code: [Select]label = "";
in constructor

I not see a problem in having a parameter [label] extra .... you can
do your label = ""

2. The change  (int)position to  (int)id  can solve some custom row
... [done in revision 34.1]

3. I think your problem begin with a  project outdated , after some
revision ...

Please, we will follow the following guide:

I. save yours specifcs java code  [Controls.java]

II. upgrate from github ..[now!].

III. From Lazarus IDE ---> Tools ---> [Lamw] Android Module  Wizard
---> Upgrade Code Templates [all!]

IV. Now, you have a problem!

you old/original "OnClickItem" signature lost the compatibility!

yes, the old signature not have "caption"!

but your can see in your new genereted "controls.lpr" code:

Code: [Select]procedure pOnClickCaptionItem(PEnv: PJNIEnv; this:
JObject; pasobj: JLong; position: JInt; caption: JString); cdecl;
begin
  Java_Event_pOnClickCaptionItem(PEnv,this,TObject(pasobj),position,ca
ption);
end;

and here is a coherent implementation:

Code: [Select]Procedure Java_Event_pOnClickCaptionItem(env: PJNIEnv;
this: jobject; Obj: TObject;index: integer; caption: JString);
var
   pasCaption: string;
 _jBoolean: JBoolean;
begin
  gApp.Jni.jEnv:= env;
  gApp.Jni.jThis:= this;

  if Obj is jListVIew then
  begin
    jForm(jListVIew(Obj).Owner).UpdateJNI(gApp);
    pasCaption := '';
    if caption <> nil then
    begin
      _jBoolean:= JNI_False;
      pasCaption:= string(
env^.GetStringUTFChars(env,caption,@_jBoolean) );
    end;
    jListVIew(Obj).GenEvent_OnClickCaptionItem(Obj, index,
pasCaption);
  end;
end;

and and here is a coherent definition:

Code: [Select]  jListView = class(jVisualControl)
      FOnClickItem  : TOnClickCaptionItem; 
  private
  ...................
  protected
      procedure GenEvent_OnClickCaptionItem(Obj: TObject; index:
integer; caption: string);
   ....................
  end;

where is defined:

Code: [Select]TOnClickCaptionItem= Procedure(Sender: TObject;
itemIndex: integer; itemCaption: string) of object;

lastly:

Code: [Select]Procedure jListView.GenEvent_OnClickCaptionItem(Obj:
TObject; index: integer;  caption: string);
begin
  if Assigned(FOnClickItem) then FOnClickItem(Obj,index, caption);
end;

But you old/original "OnClickItem" has signature (Obj,index) ..... and
fail!

Solution:

Get a new signature from Object Inspector to "OnClickItem" event

and copy your code to "new" OnClickItem.... just change your old
"Item/integer" param to "itemIndex/integer"

and from that point we will try to find why we still have some bugs! 

Thank you!

Hi jmpessoa

Hello @jmpessoa!

Here the solution (finally!) to my problem with click lost on
jListView with custom adapter. Problem was related to code that
accessed to alist even if was empty in onItemClickListener and the
basic hack is to call controls.pOnClickCaptionItem(PasObj,
lastSelectedItem, "") with a empty Caption (last parameter) and check
with isEmpty if alist is or not empty.

Code: [Select]/////////////////
Controls.java
////////////////
onItemClickListener = new OnItemClickListener() {@Override
        public void onItemClick(AdapterView <? > parent, View v, int
position, long id) {
                lastSelectedItem = (int) position;
                if (!isEmpty(alist)) { // this test is necessary !
                        if (highLightSelectedItem) {
                                if (lastSelectedItem > -1) {
                                        DoHighlight(lastSelectedItem,
textColor);
                                }
                                DoHighlight((int) id, highLightColor);
                        }
                        if (alist.get((int) id).widget == 2 /*radio*/
) { //fix 16-febr-2015
                                for (int i = 0; i < alist.size(); i++)
{
                                        alist.get(i).checked = false;
                                }
                                alist.get((int) id).checked = true;
                                aadapter.notifyDataSetChanged();
                        }
                        controls.pOnClickCaptionItem(PasObj, (int) id,
alist.get((int) id).label);
                } else {
                        controls.pOnClickCaptionItem(PasObj,
lastSelectedItem, ""); // avoid passing possibly undefined Caption
                }
        }
};

this.setOnItemLongClickListener(new
AdapterView.OnItemLongClickListener() {@Override
        public boolean onItemLongClick(AdapterView <? > parent, View
view, int position, long id) {
                if (!isEmpty(alist)) {
                        selectedItemCaption = alist.get((int)
id).label;
controls.pOnListViewLongClickCaptionItem(PasObj, (int) id,
alist.get((int) id).label);
                        return false;
                }
                lastSelectedItem = (int) id;
                return false;
        }
});

}
public static boolean isEmpty(ArrayList coll) {
        return (coll == null || coll.isEmpty());
}

p.s. I think that method jFree must set
setOnItemLongClickListener(null) too

New method jHttpClient.DeleteStateful

The method implements the DELETE with 2 parameter: Url and Value.
Useful for REST server that will receive a call like this, made with
DELETE method:

http://Url/Value

Code: [Select]/////////////////

////////////////

  end;
  env^.DeleteLocalRef(env,jParams[0].l);

I just tried the NoGUI and it seems broken. There are at least 3
scenarios, all after filling the initial dialog:
Nothing happened (folder structure created except jni), could happen
for the first time use where JNIAndroidProject.ini already
existsSecond dialog appears, right click on App.java and get simonsayz
templates then click OK -> List index out of bound (-1)Delete
JNIAndroidProject.ini first, in the second dialog, don't directly
click OK but double click Controls.java first and see the Pascal
interface, only after that click OK -> Could not change directory to
"path to project/obj/controls" Directory not existsCould you test?

Hello @jmpessoa!

I'm trying to use jImageBtn in order to replace normal buttons but
can't find the right road.
Which is correct method to load an image as background resource  in
jImageBtn?
The sample jImageBtn in AppMenuDemo won't work.
My intent is to replace all buttons with jImageBtn loaded with images
taken from Android icons pack in material style (rounded).

Same trouble changing backgroundcolor of a Form or Panel. Changin
color from palette work, but it where very nice changing
backgroundcolor loading directly the color resource into color
settings, using name, not numeric representation.

It is possible to change font for entire App?

A minor typo in jPanel. Having an object inside it (i.e. jEditText),
his property MarginBottom is not read and has no effect.

Have you plan to add the Navigation Drawer and Floating Action Button?

Thank you!

if load music or video from internet, they will be downloaded and
saved to cache memory first, then played, we must wait some minutes if
them have large size (>some megabytes)
So I want to ask do we can load and play at the same time ?

Hello liuzg2

Quoteps: a  webservice server address 
 http://localhost:9001/Service/logon?wsdl
  then  client call    logon(name,password)

With jHttClient you have a full suite of opportunities:

Set authentication:

Code: [Select]  jHttpClient1.SetAuthenticationHost('',-1);
  jHttpClient1.AuthenticationMode:=autBasic;   
  jHttpClient1.SetAuthenticationUser('username', 'password');

make a post:

Code: [Select]  jHttpClient1.AddNameValueData('name','value');
  jHttpClient1.AddNameValueData('anothername','anothervalue');
  jHttpClient1.PostStateful('http://yourhost');  

using Get:

Code: [Select]  string :=
jHttpClient1.Get('http://yourhost/getservice');

Call Delete method:

Code: [Select] 
jHttpClient1.DeleteStateful('http://yourhost','whattodelete');

See example in demos/Eclipse/AppHttpClientDemo1 too.

Hello jmpessoa!

here some question related to jSqlite and Cursor .

freepascal don't permit to overload functions and procedure with same
parameters, so

function jSqliteDataAccess.Select cannot be used!

Adding a second parameter to the procedure (i.e. gotolast: boolean def
to false) can make possible to use the function Select.

In Controls there are some typos:
Code: [Select]      public String SelectS(String selectQuery) {
//return String
...
                    try
----->>>>>         this.cursor = null; // without this a second query
will find the Cursor randomly positioned!!!

.............

            public void SelectV(String selectQuery) {   //just set the
cursor! return void..
                    this.cursor = null;
                        try{                   
                                if (mydb!= null) {
                                   if (!mydb.isOpen()) {
                                      mydb = this.Open();
//controls.activity.openOrCreateDatabase(DATABASE_NAME,
Context.MODE_PRIVATE, null);
                                   }
                                }

Nice, less unneeded option since practically all Eclipse projects are
Ant-compatible, just provide a proper build.xml.

With last revision, under Linux, it is still impossible to create a
new Application.
Selecting JNI Android Module [Lamw GUI] from New menu the error
message is:
"Unable to create file build-debug.bat"

@jmpessoa

With new revision 36, on Linux, this problem is resolved, thank you!
Now compiling this is the error message:

Fatal: Cannot find unit system used from controls in LCLBase.

LCLBase is used only on Windows system and is not required on Linux.
Where do I find the reference to LCLBase?

Thank you!

I can't use this code in lamw,app will close when I excute asynctask,
I don't know why   . I am using unit fphttpclient

Code: [Select]procedure

Ok, I will do some test...

@renabor

LCLBase is need only to install components Icons as resource 
[LResources.pas] ... but

a 'Lamw" cross-compile project do not need any reference to it!

@m4u_hoahoctro

Please, use jHttpClient! there some demo....

few attempts:

1.may be accidentally your project became  LCL  dependent...
[Project --> Project Inspector ]

2.If you got an "old" project then try  "Run" -->> "Clean up and
Bulid"

3. You can try open "tfpandroidbridge_pack.lpk" --->> "recompile
clean" --->> Install

@jmpessoa, you are rigth! That was, nr 1!

And now some improvements to code, related with jListView.
Implementing a floating panel that can be used as a lateral menu, I
haved problems with fling at panel level.
In my form I have a jPanel and over it a jListView. The onFling method
is handled by jPanel but jListView intercept the Event and block it
delegating his handling to parent ViewGroup, not to jPanel.
Solution was to add an TouchListener in jListView code.

Code: [Select]private OnTouchListener onTouchListener;
private float mDownX = -1;
private float mDownY = -1;
private float pressure = 1;
private final float SCROLL_THRESHOLD = 10;
private boolean isOnClick;
private boolean canClick;

onTouchListener = new OnTouchListener() {@Override
        public boolean onTouch(View v, MotionEvent event) {
                int action = event.getAction() &
MotionEvent.ACTION_MASK;
                switch (action) {
                        case MotionEvent.ACTION_DOWN:
                                canClick = false;
//                              Log.i("ACTION", "DOWN");
                                mDownX = event.getX();
                                mDownY = event.getY();
                                isOnClick = true; // blocco la
propagazione
                                break;
                        case MotionEvent.ACTION_CANCEL:
                        case MotionEvent.ACTION_UP:
                                if (isOnClick) {
//                                      Log.i("ACTION", "UP");
                                        canClick = true;
                                } else {
//                                      Log.i("ACTION","UP NOT
PROCESSED");
                                }
                                return false;
                        case MotionEvent.ACTION_MOVE:
                                if (isOnClick && (Math.abs(mDownX -
event.getX()) > SCROLL_THRESHOLD || Math.abs(mDownY - event.getY()) >
SCROLL_THRESHOLD)) {
//                                      Log.i("ACTION", "MOVE");
                                        isOnClick = false;
                                };
                                return false;
                };
        return false;
        };
};
setOnTouchListener(onTouchListener);

and for better cooperation with OnClickListener, some addition to its
implementation

Code: [Select]onItemClickListener = new OnItemClickListener()
{@Override
        public void onItemClick(AdapterView <? > parent, View v, int
position, long id) {
                lastSelectedItem = (int) position;
--->>>  if (canClick) {
//                      Log.i("ACTION", "CLICK");
                        if (!isEmpty(alist)) { // this test is
necessary !  //  <----- thanks to @renabor
                                if (highLightSelectedItem) {
                                        if (lastSelectedItem > -1) {
DoHighlight(lastSelectedItem, textColor);
                                        }
                                        DoHighlight((int) id,
highLightColor);
                                }
                                if (alist.get((int) id).widget == 2) {
//radio fix 16-febr-2015
                                        for (int i = 0; i <
alist.size(); i++) {
                                                alist.get(i).checked =
false;
                                        }
                                        alist.get((int) id).checked =
true;
aadapter.notifyDataSetChanged();
                                }
                                controls.pOnClickCaptionItem(PasObj,
(int) id, alist.get((int) id).label);
                        } else {
                                controls.pOnClickCaptionItem(PasObj,
lastSelectedItem, ""); // avoid passing possibly undefined Caption
                        }
                }
        }
};
setOnItemClickListener(onItemClickListener);

and same to OnItemLongClickListener
Code: [Select]this.setOnItemLongClickListener(new
AdapterView.OnItemLongClickListener() {@Override
        public boolean onItemLongClick(AdapterView <?> parent, View
view, int position, long id) {
--->>>  if (canClick) {
                        if (!isEmpty(alist)) {  //  <----- thanks to
@renabor
                                selectedItemCaption = alist.get((int)
id).label;
controls.pOnListViewLongClickCaptionItem(PasObj, (int)id,
alist.get((int)id).label);
                                return false;
                        };
                        lastSelectedItem = (int)id;
                };
                return false;
        }
});

Hello @jmpessoa!

I need some helps.
Trying implementing FAB inside of jListView i'm unable to resolve 2
problems with image visualized.
Image appears and this is good, but centered in top of screen and not
bottm right as I will.
And can't find a solution to inform my code that a click is succeded.
From pascal I use this line that works fine (source attached)

Code: [Select]jListView1.SetFab(jImageFileManager1.LoadFromResources('
ic_android'));

and this is code related added in Controls.java

Code: [Select]public void setFab( android.view.ViewGroup viewgroup ,
Bitmap imageBmp) {
  ImageView imageView = new ImageView(ctx);
  imageView.setImageBitmap(imageBmp);
  imageView.setLayoutParams(new
LayoutParams(LayoutParams.MATCH_PARENT,LayoutParams.WRAP_CONTENT,
Gravity.BOTTOM));
  viewgroup.addView(imageView);
       imageView.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
//                Log.i("FAB","CLICK");
                controls.pOnClickFab(PasObj);
            }
        });
}

All works as expected, but when I click on Fab image I get this error:

Code: [Select]E/art     ( 9774): No implementation found for void
com.suevoz.borsa.Controls.pOnClickFab(long) (tried
Java_com_suevoz_borsa_Controls_pOnClickFab and
Java_com_suevoz_borsa_Controls_pOnClickFab__J)
E/AndroidRuntime( 9774): java.lang.UnsatisfiedLinkError: No
implementation found for void
com.suevoz.borsa.Controls.pOnClickFab(long) (tried
Java_com_suevoz_borsa_Controls_pOnClickFab and
Java_com_suevoz_borsa_Controls_pOnClickFab__J)

One solution I tried was such a method in constructor, but is not
working:

Code: [Select]onFabClickListener = new OnClickListener
handleOnClick(final Button button) {
View.OnClickListener handleOnClick(final Button button) {
    return new View.OnClickListener() {
        public void onClick(View v) {
          controls.pOnClickFab(PasObj);
        }
    };
}
------------
public  native void pOnClickFab(long pasobj);

any idea?

Thank you in advance!

----------------------------------------------------------------------
jmpessoa · 2015-08-12 17:57

@renabor

1. Change here:

Code: [Select]public void setFab(Bitmap imageBmp) {
  ImageView imageView = new ImageView(controls.activity);
  .....................
}

and Pascal side too!


2. what about "controls.pOnClickFab(PasObj)",  it is "well-defined"?

   2.1 you put a new entry in "ControlsEvents.txt"   -->>  "..\java" ?
         if true then --->> Lazarus IDE ---> Tools -->> Lamw --->
"upgrade code
templates"

             EDITED: You need put there  [ "..\java"] the your new
"Controls.java"   too!!

Hello guys, does any of you has seen this error in your applications:

Code: [Select]A/libc(30743): Fatal signal 11 (SIGSEGV) at 0x00000000
(code=1)
My application crashes, and logcat show this message, whenever I try
to use jHttpClient.OnContentResult.

After some digging, I've found that after Android 4.0, they've changed
the memory management and, most of JNI codes present this same kind of
error. Does it makes sense also in LAMW?

Hello , installing the package the nuts do Lazarus me this , why?

@Euller,

Quote... I've found that after Android 4.0 ...

No, In my test, I compiled with android 4.2  [target 4.2, too], and it
is ok!


@xinyiman

In my system the source of "CustApp" is in
"C:\laz4android\fpc\x.y.z\source\packages\fcl-base\src"

and your "homemade" android cross-compile should generate
"custapp.tpu" in "...\fpc\x.y.z\units\arm-android"

a question, this guide "new_how_to_install_by_renabor.txt"  is still
valid and relevant to install everything on linux? Or it is partial
and must follow another?

Hello @xinyiman!

I've updated the guide, integrating it with more specific steps.
A note on fpc version, that must be 2.6.4 for compiling the trunk
version (3.1.1).
If you have Ubuntu 14.04 (like me) you must download the correct
version from here:
http://packages.ubuntu.com/vivid/fpc-2.6.4

Thank you!

Thanks you're an angel. Really I want to create a virtual machine

it to those wishing to try download without exhausting in preparing
the car.

----------------------------------------------------------------------
euller · 2015-08-27 16:38

I've discovered the problem. but still didn't find a solution.
Here is the deal, when I call jHttpClient.OnContentResult, I receive a
string named content right? Well, I use this string to fill a JSON
array, and use that array to fill a ListView, and boom, crashes. Right
now I'm digging up the reason, I will tell when more information is
available.

----------------------------------------------------------------------
euller · 2015-08-27 19:28

New info, doesn't matter where the code is, it simply doesn't work,
here, a sample of how it looks:

Code: [Select]procedure TMiniActivity.PopulateList(content: String);
var
  vja: TJSONArray = nil;
  i: Integer;
  s: String;
begin
  if Trim(content) <> '' then
  begin
    try
      s:='';
      vja:= TJSONArray(GetJSON(content));
      for i:=0 to vja.Count-1 do
      begin
        s:= vja.Objects[i].Strings['data_a']+' -
'+vja.Objects[i].Strings['data_2'];
        jListView1.Add(s);
      end;
    except
      ShowMessage('Operation error');
    end;
    FreeAndNil(vja);
  end;
end;
I've done this code over and over for desktop and web applications,
but in android with LAMW it doesn't work. I'm starting to suspect that
is something I'm totally oblivious going on and I've ran out of ideas
of how to find it. Does someone has any thoughts?

----------------------------------------------------------------------
jmpessoa · 2015-08-27 22:02

@Euller,

I Think your problem in " JSON" cross-compile support...  In my sytem
I have:

"C:\laz4android\fpc\x.y.z\units\arm-android\fcl-json"

and you ?

At least 2:
Make a good use of the raised exception object, try-except can explain
more precisely what happensShowMessage the content before passing it
to GetJSON, make sure it really is a valid JSON

Hey guys, here is what I think is the reason of my problem:

http://stackoverflow.com/questions/14495242/android-fatal-
signal-11-sigsegv-at-0x00000040-code-1-error

If you look at the answer instead of the question as I did, you may
came to the same conclusion I had: the two problems have the same
reason, but I could be wrong. So please help me to find an answer.

All error 11-sigsev related with my code was caused by accessing empty
array or using a cursor after a malformed sql query.
Are you sure that Strings['data_a'] and Strings['data_2'] are valid
and reachable?

s:= vja.Objects.Strings['data_a']+' - '+vja.Objects.Strings['data_2'];

Try to use variable as arry index instead of string

Code: [Select]const DATA_A = 'data_a';
DATA_2 = 'data2';
s:= vja.Objects[i].Strings[DATA_A]+' -
'+vja.Objects[i].Strings[DATA_2];

for me was a solution many times

Thank you! I'm trying install LAMW in a fresh lubuntu virtual machine
too, but I have problems in preparing lazarus deb package, the error

/usr/bin/fpcres is still present in my system, but not used, why?!?
Have you had better result?

Hello , I went addition , the preparation of the deb package of
Lazarus had no problems . I have no problem about this command because
you did not specify from which folder I launch

make clean crossall OS_TARGET=android CPU_TARGET=arm

~/Android/fpc?!

Yes, you execute the command from ~/Android/fpc

but just before you MUST create following symlinks:

Code: [Select](CMD) cd /usr/bin
(CMD) sudo ln -s /home/$HOME/Android/ndk/toolchains/arm-linux-
androideabi-4.8/prebuilt/linux-x86_64/bin/arm-linux-androideabi-as
(CMD) sudo ln -s /home/$HOME/Android/ndk/toolchains/arm-linux-
androideabi-4.8/prebuilt/linux-x86_64/bin/arm-linux-androideabi-ld.bfd
(CMD) sudo ln -s /usr/bin/arm-linux-androideabi-as arm-linux-as
(CMD) sudo ln -s /usr/bin/arm-linux-androideabi-ld arm-linux-ld

N.B. if you use reference to 4.8 here, you must ensure to use
reference to 4.8 everywhere when configuring LAMW

compiler can't find it.

have you adapted build.xml to your system?
have you downloaded the necessary sdk library for your target?

You are on the right path jmpessoa, org.apache.http.client was removed
in API 23. It is better, xinyiman, that you target your app to API 21,
just to avoid such problems

Yes, before calling the method I've assured that I had something to

One more question, to find an example of the use of tested and working

simonsayz · 2015-09-12 15:07

Always Thanks.

Just Tip for using Android Module Wizard

Maybe, Android 6.0 policy will be changed.

Android 6.0 (API =23) can't loading App when has Text Relocations.
Until today, FPC generate shared library with RextREL,
So, When set API =23, App will be crashed.

dlopen.html


## Updated Information (09.18.2015) ##
svn r31739 : FPC supports the PIC
Now, FPC app works on Android 6.o (targetSDK = 23)
Thanks to Yury Sidorov

anything like that?

Also as a component should I use to use the tab?

jmpessoa · 2015-09-19 17:22

@m4u_hoahoctro

Yes, we have some problems  with API = 23

1. jHttpClient fail!

 solution:  redesign jHttpClient code is need ....

2. FPC fail!

solution by simonsayz:

http://forum.lazarus.freepascal.org/index.php/topic,29713.0.html

@TrueTom,  

what a about a new "Laz4Android"  with FPC simonsayz patch?


@xinyiman,

There are:

 "jGridView" component and "AppGridViewDemo1"


"jActionBar" component  and "AppActionBarTabDemo1"

Please,  Upgrade demos code:

Lazarus IDE --> menu Tools --> [Lamw] Android Module Wizard -->
Upgrade code Templates [*.lpr, *.java]

More info about "demos" use: "readme.txt"

Thanks to All!!!

So it means my app ( including component jhttpclient) will cant run on
android M ?

----------------------------------------------------------------------
jmpessoa · 2015-09-20 14:31

@m4u_hoahoctro,

Yes, but you can run it [on "M"] just now!

What you can not do is compile with [sdk] API=23 or target API=23 ...

[NOTE: I don't have an "API 23" real device .. so, I have not done any
test ...]

As soon as possible I will redesign/recode "jHttpClient" ... [in fact
these days I have been very very busy... sorry ...]

guys, is there any component, besides the sqlite one, that stores
information of the application, even if the device shut down?

----------------------------------------------------------------------
jmpessoa · 2015-09-24 17:31

Hello Euller!

You can try "jPreferences" component to store/read "key=value" pair!


    function GetIntData(_key: string; _defaultValue: integer):
integer;
    procedure SetIntData(_key: string; _value: integer);

    function GetStringData(_key: string; _defaultValue: string):
string;
    procedure SetStringData(_key: string; _value: string);

    function GetBoolData(_key: string; _defaultValue: boolean):
boolean;
    procedure SetBoolData(_key: string; _value: boolean);

Ok,  duplicate unit "controls" is bad, but not an "error" [you got

Hello xinyiman!

As said by jmpessoa, the error is related to

Code: [Select]arm-linux-androideabi-ld not found

to resolve you can add proper dir in $PATH or make symbolic link to
both ld and as, this way:

################
create symbolic link for linker
################

(CMD) cd /usr/bin

Are you able to compile with 4.9? After some attempts and many errors
I revert to 4.8.
In Project->Project Option have you all paths sets according to your
choice of using 4.9?
There are 2 points to control: Paths and Others

Hello, I wanted to ask you something, I used a grid to see the data,

Hello @xinyiman!

I'm sorry but I never used jGridView1, but you can install the app
AppGridViewDemo1/bin/AppGridViewDemo1.apk and then give a look at the
source  AppGridViewDemo1.
For further inspiration take a look into unit gridview.pas, where
class jGridView is defined

----------------------------------------------------------------------
xinyiman · 2015-09-30 16:13

I tried to look, but the example only shows how to add fields in the
grid. For example, it does not explain how to change them. Why pensado
add a editbox by which to modify the data of the selected cell.

Hi jmpessoa. Thanks for your hard work.
But i'm having a problem. When i create new project with JNI (Lamw
GUI), it response a error message only: "List index (-1) out of
bounds".
All version installed is newest: laz4a 1.5 49903 and lamw which i have
just downloaded 2 hour ago.

----------------------------------------------------------------------
DonAlfredo · 2015-10-06 14:16

@jmpessoa
First, thanks for a very nice tool !
However, I am encountering a strange problem.

E.g.
I have a datamodule (form) with two ImageViews.
App runs fine.
I add a third ImageView.
App crashes on startup.
I add a fourth ImageView and delete the third ImageView.
App runs fine.

Can you help ?
Thanks.

Hello  Sait! Hello All!

I just  downloaded [today] lamw  from "github" and yes, it was not
working... sorry

But now [after some fixs], I think it is Ok!

Thanks to All!

----------------------------------------------------------------------
DonAlfredo · 2015-10-07 09:27

Thanks !
Works much better (100%) with the new version !!
(drawback: I had to recreate the whole project to get the positive
effects)

Few questions remain:

1)
I have a jTextView on my form.
I set text property to empty string (delete contents)
I set hint to display some text on empty showup.
Works well.
Close project.
Open project
Text property is filled again.
E.g.: I have to delete the text property by hand everytime I open the
project !

2)
I have a jTextView inside a jPanel.
Setting the vertical size to matchparent (jPanel) causes some strange
effects when dragging or editing the jPanel and/or the jTextView.

3)
I have made a simple demo project (copy of Sample 1) using the mORMot
(http://synopse.info)
Would you like to include it into the LAMW samples ?

----------------------------------------------------------------------
Sait™ · 2015-10-07 10:29

else if jSwitchButton1.State=tsOff then ShowMessage('Off');end; When I
toggle the switch button, the property Sate 's value is always tsOff,

About Image:

then [in design time .... or in run time "OnJNIPrompt"]:

Hi,
would it be a big change to add "Android Module Wizard" and package
"CustomDrawn"  into the Laz4Android package? (truetom??)
If this would be added, the user's could use laztoapk to get all stuff

if rotate = 1 --> device is in vertical    [default position]

Wouldn't it be better to use enum instead of integer?

Hello jmpessoa,

I have updated the new version laz4android-50093,
I also used the new LAMW which is download today.
But when I create new project with JNI Android Module (Lamw NoGUI or
Lamw GUI),
it only show me a error : "List index (-1) out of bounds".
Please help me to fix this problem, thank you!

Thanks and best regards!

I think the same way. This isn't the place to discuss where and when
to use enums, but some meaningful names are helpful to the person
using the tool. But this isn't a major flaw that compromises the
usability of LAMW, it's just an odd design choice that isn't
prejudicial to the development cycle.

Someone else has already reported this issue/bug ...I think it may be
related to fill some listbox/combox in unit "uformworkspace.pas" ... 
still can not identify why it occurs in some case ... I will continue
trying to fix it!

@Euller and Leledumbo

Yes, the code has [some/many] immature design... all suggestions are
welcome
[we can improve it]!

Thanks to All!

An thing that I've just found about jDialogYN, let me show with some
code

Code: Pascal  [Select][+][-]window.onload = function(){var x1 =
document.getElementById("main_content_section"); if (x1) { var x =
document.getElementsByClassName("geshi");for (var i = 0; i procedure
TAndroidModule1.DoBar;begin   DoFoo('yeah');// something that may
fail   jDialogYN1.Showend; procedure
TAndroidModule1.jDialogYN1ClickYN(Sender: TObject; YN:
TClickYN);begin   if YN = clickNo then     DoBarend; procedure
TAndroidModule1.AndroidModule1JNIPrompt(Sender: TObject);begin 
 jDialogYN1.No:= 'No';   jDialogYN1.Yes:= 'Yes';   jDialogYN1.Msg:=
'The application has executed DoFoo?';   jDialogYN1.Title:=
'Foo';end; 
Well, this should create an loop, where DoBar calls DoFoo to do its
thing that may fail, and that fail is obvious to the user, and then a
dialog shows up asking the user if the operation was done. If it was,
the program flow should return to normal, if it wasn't, DoBar is
called again.

But I've noticed that, when I try to do it, there is no loop,
jDialogYN1 is not showing again? Is that supposed to happens?

@jmpessoa

Hello jmpessoa,

I have found this problem,and fixed this problem.
When the error is show , I found in the file "JNIAndroidProject.ini /
AndroidPlatform=-1" , then I change it to 0 ,this error not show.
You are right , it's in the file "uformworkspace.pas" , read the
"FAndroidPlatform" is not validity, I change
ListBoxPlatform.ItemIndex:=0 to fixed this problem.

Thanks and best regards!

Hello. I'm new to this thread. I have one question regarding
jHtppClient.
Is it possible to retrieve gzip response from server and somehow
ungzipit via jHttpClient component.


var MyString
begin
  jHttpClient1.AddClientHeader('Accept-Encoding', 'gzip');
  MyString :=
jHttpClient1.Get('http://some.server.which.return.gzip');
  // MyString is compressed - how to uncompress
end;

Second question. Is there any way to save String to file which is
available (visible) via usb cable and some storage folder on phone

Regards, Dinko

----------------------------------------------------------------------
jmpessoa · 2015-11-05 00:04

Hello dinmil!

QuoteSecond question. Is there any way to save String to file which is
available (visible) via usb cable and some storage folder on phone...

Yes! You can use jTextFileManager component and "CopyFile" ...

[see demo AppShareFileDemo1]

Code: Pascal  [Select][+][-]window.onload = function(){var x1 =
document.getElementById("main_content_section"); if (x1) { var x =
document.getElementsByClassName("geshi");for (var i = 0; i  
 //myString: string;      //save to Internal App Storage    
jTextFileManager1.SaveToFile(myString, 'hello.txt');     //copy to
"public" folder download ...     Self.CopyFile(Self.GetEnvironmentDire
ctoryPath(dirInternalAppStorage)+'/hello.txt',                       
  Self.GetEnvironmentDirectoryPath(dirDownloads)+'/hello.txt');   
For now I could not answer question 1... please try it!

----------------------------------------------------------------------
dinmil · 2015-11-05 13:13

I checked AppShareFileDemo and tried to Copy hello.txt to
/download/public.
Function returns that Copy is OK but it is not visible ouside of
phone. Even file manager of phone can not find the file.
Path say that this is /emulated/0/downloads  path or something like
that.
I have HTC 310 for test which is not routed.

About httpclient.get method. This method returns utf unicode string.
So if server returns gzip of 33 bytes it is converted to unicode of 63
bytes.
Is there some function which will convert unicode string to byte array
or stream? This will solve problem.
Or even better, is there some function which will get http data in
stream format or byte array?

So far, I think this project is excellent. Installation is little bit
painful, but once setup is finished almost everything work OK.

Regards, Dinko

----------------------------------------------------------------------
dinmil · 2015-11-05 13:50

Copy is OK. After installing and starting Total commander for Android
I was able to find the files.

So it seems one problem is solved, still stays jHttpClient and gzip.

Regards, Dinko

Hello m4u_hoahoctro!

I use this method in order to remove tabs:

Code: [Select]  jMenu1.Clear();
  self.RemoveAllTabsActionBar();
  jMenu1.InvalidateOptionsMenu();

be sure that in your controls.java the method RemoveAllTabsActionBar
is updated:

Code: [Select]public void RemoveAllTabsActionBar() {
        ActionBar actionBar = this.controls.activity.getActionBar();
        actionBar.removeAllTabs();
        this.controls.activity.invalidateOptionsMenu();
actionBar.setNavigationMode(ActionBar.NAVIGATION_MODE_STANDARD); //API

May be i was wrong when i decided to update lamw and laz4android
I updated:
lamw's lastest version
laz4android 1.4
android ndk 10e

I confirgured paths setting, and when I choose Update Code menu (
rebuild .so lib): This error shows: Priviledged instruction ( below
image )

and so I choosed Cancel to reopen laz4, and I tried to open my project
( created by older version of lamw and laz4 ( 1.3) )
but I still got more errors ( Can see  by images I sent below )

http://i.imgur.com/3iBUa1p.png

http://i.imgur.com/lc36CtX.png


after some hours, I used backup version of my project and reopen it
everything is ok until I choose Run and build apk file menu
As this image, I choosed Yes to all because i updated ndk to r10e
http://i.imgur.com/wtXyjbI.png

then a dialog appears, and i dont know which  should be chosen

http://i.imgur.com/LvTGDdO.png

I need a solution from others, thanks

----------------------------------------------------------------------
jmpessoa · 2015-11-13 14:46

Hello M4u

1.

 You need download ndk10e


2.

Go to "C:\laz4android\config"

and change  "JNIAndroidProject.ini"  lines:

PathToAndroidNDK=your "ndk10e" path
NDK=3


3.

For old projects open "*.lpi" and change NDK path and replace "4.6" to
"4.9"

JNIAndroidProject.ini is located in lazarus configuration directory,
not your app (it's global for all of your LAMW projects).

----------------------------------------------------------------------

Yes,

Go to "..\laz4android\config"     // << -----------------

Well, if  you not have "JNIAndroidProject.ini"  in  your new
laz4android install, then
you can copy from the old install [and fix it]

or:

go to Lazarus IDE menu  ---> Tools ---> [Lamw] ---> Paths Settings

Hello, I would have a couple of questions. How do I ensure that a
jtextbox accept only numbers?

How do I use the JTIMER?

Are there examples?

Then I wanted to know, there is a guide that explains clearly the best
methods to manage the look and feel of an application made with 
Android (LAMW)?

Thank you

Hello,

try  to answer your question.

1. set Property InputTypeEx:= itxNumber;
2. When jFrom create , set jTimer enabled to true,
jTimer1.enabled:=true;

Thanks and best regard!

LAMW now support  android "themes"...  so you can get the android 
"look and feel" by Just

selecting a theme [create new project]:

   DeviceDefault
   Holo.Light.DarkActionBar 
   Holo.Light 
   Holo
   Material.Light.DarkActionBar
   Material.Light
   Material

From install_tutorial.txt
Code: [Select]1. Configure Paths:

                -Path to Java JDK

I do not have a \Laz4Android\components\LazAndroidWizard\java folder

I have a \lazandroidmodulewizard-master\java folder which is the same
as
https://github.com/jmpessoa/lazandroidmodulewizard/tree/master/java
but this not inside \Laz4Android\components

is this what it means?

My laz4android build is made from laz4android1.5-50093-FPC3.1.1.7z

thanks

Apk and Run"

It did not install, however I took file

manually copied to SD card, and install from phone file manager

The output from adb logcat is below, what was my mistake?

1. just a reminder: your device was prepared for "debug/development"

2. You do "build" before "[Lamw] Build Apk and Run" ?

Yes.

I do not mind if the APK is automatically installed, or not.  I can
install it myself.  The problem is that it crashes when run on the
phone.

Hello  dieselnutjob!

1. A first problem....  you do a small and deadly/fatal modification .
Please, unchecked the "the pass option to linker with -k..."  and
clear the Edit below...  Now you will get a correct ".so" [~ 575 k]


2. Check your
"...\LamwGUIProject1\bin\classes\org\lamw\lamwguiproject1" folder ...
the correct is 136 files


Note: the discussion about android 5.0 "pass option to linker with
-k..."  Is not applicable to produce a Lamw  ".so"

Delete the folder  "\bin" from "...LamwGUIProject1\bin\" 

and more: delete the Apk from device, too.

take care of all configs for you!]

instead of the "download zip" function of the website.

The old folder had 4388 files
The new folder (done with SVN) has 6581 files !

I will re-install everything and try again

----------------------------------------------------------------------
jmpessoa · 2015-12-24 23:02

Hi dieselnutjob!

Ok. Good Job!

But, I think your installation was correct! The master zip is OK!

What about use some "c:" folder and not "d:" folder for
development....[just guessing
!]

The message box error is quite strange!

----------------------------------------------------------------------

DelphiFreak · 2015-12-25 07:11

Hello dieselnutjob,

I am the developer/maintainer of laztoapk.
You have spent now some time to get your problems solved and learned
to use both tools. (laztoapk and lamw).
I have very limited sparetime and could not get into lamw so far.
Could you shortly share your expirience now for other folks interested
in doing android stuff with lazarus?

Would it make sense to merge lamw and laztoapk into one setup?

My intention for laztoapk was: Help people to get all this tool-chain
stuff configured/setup correctly to let a user make his first app 
without much pain !

Regards,
Sam

----------------------------------------------------------------------
dieselnutjob · 2015-12-25 07:57

There is one fundamental difference between the two approaches.

laztoapk sets up an environment which uses customdrawn
lamw uses something else, I have not figured out exactly what it is
yet

at least that is my understanding

There are some problems with my installation.  When you create a new
project it will crash at first, and you must restart lazarus to make
it work.  However it makes working Android apps so it is still
brilliant!

I think that the best thing would be for me to start again with a
blank PC.  I will repeat what I have done, and write down exactly what
I have done so that you can repeat it yourself easily.

If you can repeat my instructions, and then turn this into a program /
script that does this automatically, which will be 90% the same as the
existing laztoapk then I think that this will be something useful,
especially for other newbies.

I need some help from you.
I have two files on my c: drive. They are sdk.zip and ndk.zip
I think that these files have been downloaded by laztoapk
can you tell me the url that laztoapk has used to download these
files?

I think that you should replicate my setup (and I will help you to do
this), and then I think that you should make your own decision whether
to change laztoapk to support lamw instead of/as well as customdrawn.

----------------------------------------------------------------------
DelphiFreak · 2015-12-25 09:27

Hello,

the answer to your question is here: http://sourceforge.net/p/laztoapk
/svn/HEAD/tree/trunk/install/laztoapk.iss

This is the innosetup-script that builds the setup.exe of laztoapk.
Look at section _ISDownload. You will find there the url's for sdk and
ndk.

Sam

----------------------------------------------------------------------
DelphiFreak · 2015-12-25 09:38

Hi, one thing more ...

things are a little more complicated.....because laztoapk depends on
laz4android.
I would prefer to have a laz4android package with pre-installed lamw.
Then I would adapt my laztoapk setup to contain a default/template-
project for lamw.
As I can see the customdrawn-package is not really
maintained/supported anymore.

I think this would be the best solution for everyone?

Sam

----------------------------------------------------------------------
jmpessoa · 2015-12-25 15:19

Hello DelphiFreak!

Quote... because laztoapk depends on laz4android.

What about LazToApk as a "Lazarus" IDE new entrypoint/item  for  menu
"Tools"?

Thank you!

----------------------------------------------------------------------
DelphiFreak · 2015-12-25 18:12

hi, yes an entry in tools menue called ”build&deploy app" would be
nice. In fact laztoapk generates the batch-files to do this. so if you
can give me a hint how to start windows batch from lazarus tools menue
i will try to do it. sam

----------------------------------------------------------------------
dieselnutjob · 2015-12-25 18:18

okay people
check this out
http://www.pscan.eu/dev/lamw_howto.zip

This is an openoffice / libreoffice doc which explain exactly how I
got my install working on Windows 10 Home 64 bit.

Everthing is in one folder called C:\lamw

----------------------------------------------------------------------
jmpessoa · 2015-12-25 20:00

Hello, @DelphiFreak!

Here [Attachment] is a draft "laztoapk" package to add IDE menu entry
point! 
Could serve as a kick start for your work!


Hello, @dieselnutjob!

I put  the "HOW_TO_INSTALL_by_Dieselnutjob.pdf" in Lamw github!

Thanks to All!

----------------------------------------------------------------------
dieselnutjob · 2015-12-25 20:12

i found that with sdk version 15 that it will build the .so file but
it will not create the apk file. When I changed to sdk 17 it started
to work. Hopefully none of my customers have devices older than
jellybean

----------------------------------------------------------------------
jmpessoa · 2015-12-25 20:26

Go to [your]

"C:\Develop\android\android-sdk-windows\platforms"

What you found? [the platforms that your system can generate the apk!]

----------------------------------------------------------------------
DelphiFreak · 2015-12-25 20:49

Hello  jmpessoa,

thanks for your answer. I will try this out but it will take a while
because I go for holiday's tomorrow.

@dieselnutjob: I had a look at your instruction document.  I think
page1-8 is covered by laztoapk setup & pdf :
http://sourceforge.net/projects/laztoapk/files/Lazarus%20and%20Android
.pdf/download

So if we could motivate the creator of the laz4android package to
include lamw by default, then I could remove "customdrawn" from my
instruction manual and
add the last three pages from dieselnutjob to my manual.
And of course I would try to add the already discussed "build&deploy
app" to tools menu of lazarus.

My code


procedure TAndroidModule2.Txt_SviluppoEnter(Sender: TObject);
begin
     Txt_Sviluppo.SetImeOptions(imeActionDone);
end;

and

procedure TAndroidModule2.AndroidModule2JNIPrompt(Sender: TObject);
begin
     Txt_Sviluppo.SetImeOptions(imeFlagNoFullScreen);
end;

But not work.
For example, they are set to Txt_Sviluppo and I click the button
btn_calcola. The keyboard that opened when I entered the Txt_Sviluppo
remains open. I want to close. How can I do?

I would also like to know how to handle exceptions.Because if use


     try
        try
          
           //nostro codice da eseguire su cui vogliamo effettuare una
gestione degli errori
           ...
          
        finally
               //codice da effettuare a fine procedura sia che va bene
il codice sopra sia che il codice ha sollevato un'eccezzione         
   
       end;
     except
           on E: Exception do
           begin
             
              //codice da eseguire solo se si verifica un eccezzione
             
           end;
     end;


 it does not work use. Thanks so much

Hello i was wondering is there any way make jListView have multiple
columns . So it can be something like DBGrid in Lazarus ? Or maybe
there is some other way to achieve this? 

And is there a way to make text inside jEditText becomes selected on
certain event.

Thank you for all your hard work !

Cheers!

jmpessoa · 2016-03-07 19:10

Hello Mladen!

1. You can try jGridView. There is a demo: "AppGridViewDemo1"

2. About jEditTex, I will do some test and try some solution...

Thank you!

----------------------------------------------------------------------
Mladen · 2016-03-09 07:26

Well yes, but as I can see it jGridView is similar to jListView, its
just arranged differently and its still one dimensional (maybe I am
wrong!). I was thinking if there is some way where you can for example
get or write data to  Row[3].Column[1] or something like that 

Thank you for your effort!

I am sorry for bothering . I am building a business application for 
android device with integrated laser barcode scanner. The device has
more physical buttons then standard android smartphone.

So I was wandering is there a way to trigger onKeyPress event just
like on Lazarus TForm component. I need it so I can turn on its laser
by pressing certian physical button which sends keycode (#131 or some
other).

On standard TForm I could do for example 
Code: Pascal  [Select][+][-]window.onload = function(){var x1 =
document.getElementById("main_content_section"); if (x1) { var x =
document.getElementsByClassName("geshi");for (var i = 0; i procedure
TForm1.FormKeyPress(Sender: TObject; var Key: char);begin if Key=#131
then TurnOnScanner;end; 
Thank you!!

jmpessoa · 2016-03-25 16:16

There is  "OnEnter" event  to handle: go, done, next, ... keys

procedure TAndroidModule1.jEditText1Enter(Sender: TObject);
begin
      TurnOnScanner;
end;

Hi jmpessoa

I want create some component in run-time but some of property don't
work or wrong result.

For example when I put three jEdittext on form and set width, height
and fontsize it's pretty work, but when create these component
programmatically, some property wrong, look at the below code:

Code: Pascal  [Select][+][-]window.onload = function(){var x1 =
document.getElementById("main_content_section"); if (x1) { var x =
document.getElementsByClassName("geshi");for (var i = 0; i procedure
TAndroidModule1.jButton1Click(Sender: TObject);var  Cells: array
[1..3] of jEditText;beginfor I := Low(Cells) to High(Cells) -6  do  
 begin  Cells[i] := jEditText.Create(Self);// It's work 
Cells[i].Parent := jPanel1;// It's work  Cells[i].Name := 'Cell' +
IntToStr(i) + IntToStr(j);// It's work  Cells[i].Text := '';// It's
work  Cells[i].Height := Ord(lpOneFifthOfParent);// Don't work 
Cells[i].Width := Ord(lpOneThirdOfParent);// Don't work 
Cells[i].FontSize := 12;// Don't work  Cells[i].Left := i * (Cells[i,
j].Height + Space) - 20; // It's work but wrong  Cells[i].Top := j *
(Cells[i, j].Width + Space) - 20; // It's work but wrong 
Cells[i].Alignment := taRight;// It's workend;
Please help me.

----------------------------------------------------------------------
molly · 2016-04-04 14:23

@developing:
Hmz, not wanting to sidetrack too much, as this is not really my kind
of topic.

But, do you have some kind of magical height vs width distance formula
that makes it plausible to use:
QuoteCells.Left := i * (Cells[i, j].Height + Space) - 20; // It's work
but wrong
Cells.Top := j * (Cells[i, j].Width + Space) - 20; // It's work but
wrong
Instead of (which is more commonly seen):
QuoteCells.Top := i * (Cells[i, j].Height + Space) - 20; // It's work
but wrong
Cells.Left := j * (Cells[i, j].Width + Space) - 20; // It's work but
wrong
As Top and Height properties are related to each other, just as
property Left and Width are.

----------------------------------------------------------------------
jmpessoa · 2016-04-04 15:01

Hello @developing!  [Edited!]


1. About height and width: Its makes little sense in run time [each
device has its own measures...]

2. [Molly] No. I dont have a "magical" height vs width distance
formula....

Please, use:

    LayoutParamWidth =  ....
    LayoutParamHeight = .....

and

    PosRelativeToAnchor = ....
    PosRelativeToParent =  ....

Thanks!

Edited: Ok Molly. Thank you for your help!

Hello jmpessoa

I read your help and use LayoutParam... and PosRelative... in button
click event.

On my cell phone don't display anything.


Code: Pascal  [Select][+][-]window.onload = function(){var x1 =
document.getElementById("main_content_section"); if (x1) { var x =
document.getElementsByClassName("geshi");for (var i = 0; i procedure
TAndroidModule1.jButton1Click(Sender: TObject);const  Rows = 3;  Cols

Low(Cells) to High(Cells)  do    begin      Cells[i,j] :=
jEditText.Create(Self);      Cells[i,j].Visible:=True;     
Cells[i,j].Enabled:=True;      Cells[i,j].Parent := jPanel1;     
Cells[i,j].Name := 'Cell' + IntToStr(i) + IntToStr(j);     
Cells[i,j].LayoutParamHeight := lp96px;     
Cells[i,j].LayoutParamWidth := lpOneThirdOfParent;          // set
anchor for each cells      if i = 1 then      begin        if j > 1
then          Cells[i, j].Anchor:=Cells[i,j - 1];      end      else 
   begin        if j = 1 then          Cells[i, j].Anchor:=Cells[i -
1,1]        else          Cells[i, j].Anchor:=Cells[i - 1,j - 1];    
end;          // positioning for cells      if i = 1 then       
Cells[i,j].PosRelativeToParent:=[rpTop]      else       
Cells[i,j].PosRelativeToAnchor:=[raToRightOf];      if j = 1 then    
begin        Cells[i,j].PosRelativeToParent := [rpLeft];        if i >
1 then          Cells[i, j].PosRelativeToAnchor:=Cells[i,
j].PosRelativeToAnchor + [raBelow];      end      else        Cells[i,
j].PosRelativeToAnchor:=Cells[i, j].PosRelativeToAnchor+[raBelow];   
 Cells[i, j].Text:='cells'+IntToStr(i)+','+IntToStr(j);    end;end;
Even create simple component.

Code: Pascal  [Select][+][-]window.onload = function(){var x1 =
document.getElementById("main_content_section"); if (x1) { var x =
document.getElementsByClassName("geshi");for (var i = 0; i procedure
TAndroidModule1.jButton8Click(Sender: TObject);var  jEditTemp:
jEditText;  jButtonTemp: jButton;begin  jEditTemp :=
jEditText.Create(Self);  jEditTemp.Parent := jPanel1; 
jEditTemp.Text:='test';  jEditTemp.LayoutParamWidth:=lpMatchParent; 
jEditTemp.LayoutParamHeight:=lpWrapContent;  jEditTemp.FontSize:=18; 
jEditTemp.PosRelativeToParent:=[rpBottom, rpLeft];   jButtonTemp :=
jButton.Create(Self);  jButtonTemp.Parent:=jPanel1; 
jButtonTemp.Text:='press me'; 
jButtonTemp.LayoutParamWidth:=lpMatchParent; 
jButtonTemp.LayoutParamHeight:=lpWrapContent; 
jButtonTemp.Anchor:=jEditTemp; 
jButtonTemp.PosRelativeToAnchor:=[raAbove];end;
In previous method (Previous post) components created but wrong
property, and with these methods don't display anything.

Please test it.

And ohter question: How can access to sdcard and file that saved on
sdcard? And how display content of file on sdcard?(For example show
text file content)

Hello I have noticed that when I set for an example Code: Pascal
 [Select][+][-]window.onload = function(){var x1 =
document.getElementById("main_content_section"); if (x1) { var x =
document.getElementsByClassName("geshi");for (var i = 0; i
jEditText1.HintTextColor:=colbrSilver; hint color always remain the
default one.

Also when I set Code: Pascal  [Select][+][-]window.onload =
function(){var x1 = document.getElementById("main_content_section");
if (x1) { var x = document.getElementsByClassName("geshi");for (var i
= 0; i jEditText1.InputTypeEx:=itxTextPassword; first typed letter is
not hidden   Only when entering the 2nd one the first one gets hidden.

Also I was wondering is there a way to to set FontFace for jListView.
For an example on jEditText i can do Code: Pascal
 [Select][+][-]window.onload = function(){var x1 =
document.getElementById("main_content_section"); if (x1) { var x =
document.getElementsByClassName("geshi");for (var i = 0; i
jEditText1.FontFace:=FFMonospace;

And don't tell me about cross-compiling:  it isn't.

Is there anything wrong with the code above? I noticed that

Hello Handoko!

Please, try  "AppDemo1"....

Thanks you!

----------------------------------------------------------------------
Handoko · 2016-04-16 06:05

Did you mean this one?
.../Android/lazandroidmodulewizard.git/trunk/demos/Ant/AppAntDemo1

I can't see any OpenGL ES usage in the demo. Also it can't be compiled
on my computer. Please see the attached picture for the error
messages.

If I start a new Android [GUI] Module [lamw] and put some buttons, it
works. I can build apk and run on my Intel-based Android phone
(although the configuration is Android-arm).

No, the one under Eclipse folder. You can make it an Ant project
simply by providing build.xml that you can copy from the Ant demos
project and modify the values inside accordingly.

Intel based Android devices usually have libhoudini installed. It's an
ARM compatibility layer so Intel based devices can still install and
run many applications from play store which might be compiled only for
ARM.

jmpessoa · 2016-04-16 13:56

Some info:

about "build.xml"  it is already there...   [folder "... /jni" ]

But to use/test any demo App you will need:

1. configure "build.xml"  to match your system...

2. configure the ".lpi" to match your system...

NOTE 1: if you need configure for "x86" please, go to folder
"...\AppDemo1\jni\build-modes"  and see "readme.txt" to replace some
lines in ".lpi"

NOTE 2. The LAMW produce many ".bat" or ".sh" to logcat ... there are
more in  "...\utils", too

3. Lazarus IDE --> Run --> "build"   [to produce the pascal jni ".so"]

4. Connect your Device-PC  via usb ...

5. Lazarus IDE --> Run --> "[Lamw] Build Android Apk and Run"

NOTE:  All projects in "Eclipse" folder are Ant compatible .... and
can be used as explained....

Thanks All!

PS. HttpClient [updated!] now work fine when target API >=21

Thanks Leledumbo and jmpessoa for the helps.

So far I now can compile simple tests (new project with some texts and
buttons) and able to build apks that can run on my Intel phone without
changing any of the default project options generated by the LAMW.

But I have problem compiling the the AppAntDemo1. When I tried to

Hello, I'm back. I'm new in using LAMW and my only Android device is
Intel 64-bit. After a full day of testing, here I want to share what I
found. Hope it can be useful.

The demos under the Eclipse folder aren't compatible with Intel 64-bit
using libhoudini. I opened many of the demos (under Eclipse) and
followed jmpessoa instructions properly modifying build.xml and .lpi
files based on my successfully new generated app settings (which run
properly on my device). All of them can be compiled without error but
when running on my device, it said "Unfortunately, [name] has
stopped."

Even if I removed all the components on the main form and deleted all
the other forms in the demos, I still get same the result. The remain
is very basic TAndroidModule jForm class only without any components
nor events. Simply to say, it's only a blank app. So it makes me
think, there could be something generated by LAMW that causes
incompatible with Intel+libhoudini. Because if I started a new app
using LAMW, the apk works on my device. I mean, the demos were
generated using prior version of LAMW than mine (version 0.6). Can
anybody tell me, is there a way we can refresh the files generated by
LAMW but keep the 'pure' Lazarus code unchanged?

libhoudini compatibility layer is not 100% compatible with ARM. So far
I have tested jTextView, jButton, jImageView, jImageList and jTimer.
All of them work correctly on Intel device although my compiler was
set to Android-arm. But if the command jCanvasES2.Texture_Load_All is
being executed, an error will occur immediately.

All the tests above were compiled using Android-arm setting, because I
still have no luck building my Lazaurs to cross compile to
Android-i386. When try to compile to Android-i386, I got this error
message: "Fatal: Cannot find system used by fcllaz of package FCL."
Any idea what should I do?

jmpessoa · 2016-04-17 15:36

QuoteCan anybody tell me, is there a way we can refresh the files

Yes [in fact all demos should be upgraded before use] !!
Please, go to Lazarus IDE menu "Tools" ---> "[Lamw] Android Module
Wizard" --->> "Upgrade code templates"

Quote...because I still have no luck building my Lazaurs to cross

Handoko · 2016-04-18 13:03

It works.

But I'm still busy have no time to test the cross compiling feature.
One thing I'm sure is there is texture problem when running arm-built
app on Intel device. I'll found out more and report back.

Thank you.

Hello Handoko!

Thank you!

----------------------------------------------------------------------
Handoko · 2016-04-23 16:51

I'm a Linux user. Here is my command to find the "make":

The results are:

I'm not a Linux expert, but my guess, the
"C:\lazarus\fpc\3.1.1\bin\i386-win32" is in the "/usr/bin" for Linux.
But it doesn't work correctly. Can I use the one under the NDK
prebuilt?

----------------------------------------------------------------------
Handoko · 2016-04-23 17:27

(continue from my previous post)

./home/handoko/Android/android-ndk-r11c/prebuilt/linux-x86_64/bin/make
is not the correct one. It fails immediately if I click the Build
button.

./usr/share/bash-completion/completions/make
is not the correct one. It is a plain text file.

./usr/share/doc/make
is not the correct one. It is a folder.

./usr/bin/make
so it should be this one. But it also fail after several seconds of
processing.

In my computer, there are 2 lazarus folder:
Quote./home/handoko/Android/lazarus
./usr/share/lazarus/1.5.49563
My guess, the first lazarus folder (under Android folder) is the
source downloaded by subversion. The second one should be the 'real'
lazarus folder. But there is no fpc folder inside them.

Linux store exe and library files in different location compare to
Windows. Normally when installing software, Windows will put all
related files in a single folder under "Program Files", but Linux
seems to distribute them into different folders.

Hello Handoko!

Where is your fpc installed?

Where is your fpc  ".../bin"?

Quote from: jmpessoa on April 23, 2016, 08:09:45 pmWhere is your fpc

I don't know. I followed "new_how_to_install_by_renabor.txt"
instruction to put the downloaded files in "/home/handoko/Android". In
the installing process, it never asked me where to put the installed
fpc.

I use Linux find command to search my entire harddisk:
Quotecd /
sudo find -name fpc
And this is the results:
Quote./home/handoko/Android/fpc
./home/handoko/Android/fpc/utils/javapp/src/fpc

./usr/local/lib/fpc
./usr/share/doc/fpc
./usr/share/fpcsrc/3.1.1/utils/javapp/src/fpc
./usr/lib/fpc
The first two under the Android folder are the source that I
downloaded. AFAIK, when installing software in Linux, it will put the
executable file into /usr/bin, and some other files into .../doc and
.../lib folders. Unlike Windows, it doesn't put all the installed
files in a single folder (Windows use "Program Files" folder).

If you follow the instruction, you should have no problem.

What version of FPC and Lazarus are you using?

If you're a Windows user, you may want to read the thread started by
tintinux:
http://forum.lazarus.freepascal.org/index.php/topic,32370.0.html

He also created a new page explaining the installation process:
http://wiki.freepascal.org/LAMW

If you're a CodeTyphon user, you may need to adapt the code. I don't
use CodeTyphon, but I heard some say CT makes several necessary
changes of real source codes. Currently, LAMW is still on its early
stage, fixing some bugs and need updating its documentation. So I
don't think the developer will have time to make it compatible with CT
soon.

Hello , dont know if you guys have tried but when ever i tried to use
TThread in my android application it doesn't seems to work.

Code inside TThread.Execute never gets executed. I have added Code:
Pascal  [Select][+][-]window.onload = function(){var x1 =
document.getElementById("main_content_section"); if (x1) { var x =
document.getElementsByClassName("geshi");for (var i = 0; i {$IFDEF
UNIX}{$define UseCThreads}{$IFDEF UseCThreads}  cthreads, 
{$ENDIF}{$ENDIF} because without it the application crashes at start.
While on simple desktop application it works fine.

I also use jAsyncProcesses but that too also crashes my application
when executed for example in Code: Pascal  [Select][+][-]window.onload
= function(){var x1 = document.getElementById("main_content_section");
if (x1) { var x = document.getElementsByClassName("geshi");for (var i
= 0; i procedure TAndroidModule2.AndroidModule2JNIPrompt(Sender:
TObject);begin  jAsyncTask1.execute;end;And after some heavier
operation for example Code: Pascal  [Select][+][-]window.onload =
function(){var x1 = document.getElementById("main_content_section");
if (x1) { var x = document.getElementsByClassName("geshi");for (var i
= 0; i  for i:=0 to Length(AndroidModule1.myArray)-1 do    begin     
if AndroidModule1.myArray[i].article=s then        begin          
jAsyncTask1.execute;          breaK;        end;    end;
while for example when used in on jButton click event it works fine.

Cheers!

Hi

Do you want to remove or change the title displayed on the top of the
Windows ?
It is the name of the project, or of the folder.

Me too... but sorry I don't know how !

Thanks to anybody who knows !

----------------------------------------------------------------------
jmpessoa · 2016-04-28 17:04

Yes,  the name of the project =  folder.

you can try hide  action bar:

Code: Pascal  [Select][+][-]window.onload = function(){var x1 =
document.getElementById("main_content_section"); if (x1) { var x =
document.getElementsByClassName("geshi");for (var i = 0; i procedure
TAndroidModule1.DataModuleJNIPrompt(Sender: TObject);begin       
Self.HideActionBar();end; 
Thank you!

----------------------------------------------------------------------
Handoko · 2016-04-28 17:16

It also can be changed to something else.

Code: Pascal  [Select][+][-]window.onload = function(){var x1 =
document.getElementById("main_content_section"); if (x1) { var x =
document.getElementsByClassName("geshi");for (var i = 0; i procedure
TAndroidModule1.AndroidModule1JNIPrompt(Sender: TObject);begin 
SetTitleActionBar('Hello');end;
Although it works, but doesn't look good. I can see the 'original'
title before it switches to the new name.

Hi all,

First i want to say that i have discover LAMW recently and i think it
is a great solution for Android development with freepascal and
lazarus. You have done an amazing work!!!!

I started an application using jCanvasES1. I need to input keyboard
entry in the jCanvasES1.
When i touch the JCanvasES1, i can show the keyboard with the
instruction ToggleSoftInput but how can i receive the pressed key in
jCanvasES1, there is no event for that...

----------------------------------------------------------------------
jmpessoa · 2016-05-01 05:09

Hello tintinux!

I got fix the "AppCameraDemo" !!

Hello  ketch!

what keys you need?  jForm,  now have "OnSpecialKeyDown"  event ...

----------------------------------------------------------------------
ketch · 2016-05-01 10:20

Hello jmpessoa!

I render a text editor in jCanvasES1. I need to get what the user
press on the soft keyboard.
I have give a try to OnSpecialKeyDown like this:

Code: Pascal  [Select][+][-]window.onload = function(){var x1 =
document.getElementById("main_content_section"); if (x1) { var x =
document.getElementsByClassName("geshi");for (var i = 0; i procedure
TAndroidModule1.jCanvasES1_1GLDown(Sender: TObject; Touch:
TMouch);begin  AndroidModule1.ToggleSoftInput();end;  procedure
TAndroidModule1.AndroidModule1SpecialKeyDown(Sender: TObject; 
keyChar: char; keyCode: integer; keyCodeString: string; var mute:
boolean);begin  ShowMessage('SpecialKeyDown fired');end;
I press on the jCanvasES1 for show the soft keyboard, then i press
some key on the soft keyboard but the SpecialKeyDown even is not fire
(the message is never display)...

Maybe i do something wrong...

In addition, i want to have more than one jCanvasES1 with text editor
on the screen, i need to get the input only in the one who is focused.

----------------------------------------------------------------------
jmpessoa · 2016-05-01 17:57

Ok ketch!

Please, go to "App.java" [...\src\...] and  uncomment "default"

Quote@Override
   public boolean onKeyDown(int keyCode, KeyEvent event) {
      switch(keyCode) {
        .......................................
         .......................
        //default:
controls.jAppOnKeyDown(c,keyCode,KeyEvent.keyCodeToString(keyCode)); 
        
      }
     .......................
   }       

In pascal side

try:

ShowMessage(keyCodeString);

Handoko · 2016-05-02 15:35

Hello. I found somethings not working correctly, hope it can be fixed
on next release.

1. Can't build FPC 3.1.1 + Lazarus 1.6

I followed the instruction "new_how_to_install_by_renabor.txt" and
succeed to install FPC 3.1.1 + Lazarus 1.5 + LAMW. That's great, I was
very happy. So I remove all of them and perform a clean installation
of FPC 3.1.1 + Lazarus 1.6, but I failed when building Lazarus. Now, I
ended with FPC 3.0.0 + Lazarus 1.6 that I installed using deb packages
downloaded from SourceForge.

Can someone tell me, FPC 3.1.1 can't be combined with Lazarus 1.6? Or
is there anything wrong in the instruction manual?

2. LAMW doesn't accept short version of home folder name

My home folder is "/home/handoko/"
It can be shortened as "~/"

I installed following the installation instruction but I replaced all
the "/home/handoko/" with "~/". Nothing went wrong. So, somebody
please update the installation guide (to use short version home name).

Unfortunately, LAMW doesn't accept short version of home folder name.
If I use the short version name on LAMW configuration form, I'll get
error. Please see the attached image.

3. Missing NDK 11c on the configuration form

I use NDK version 11c, but there is no such option on the path
setting. Please see the attached image. Strange thing is, everything
seems working correctly although I choose 10c but actually I have 11c
installed. Why?

4. What is Linux-x8664?

Is it a typing mistake? Please see the attached image.

5. Items on the Ndk Platform listbox aren't properly sorted

It should be 14, 15, 17, 21 ... Please see the attached image.

6. Can't cross build on Linux

I'm sure my Linux make tool is in "/usr/bin" folder. But it said
cannot run extern [make] tool.

Hi All!

There is an updated LAMW revision!!

Version 0.6 - rev. 42 - 10 May 2016 -

   UPDATE!   AppMenuDemo  // <<--- thanks to Freris!
   FIXED!   OnKyDown [App.java] // <<--- thanks to Freris!

Please,
Upgrade yours projects code templates:
QuoteLazarus IDE --> menu Tools --> [Lamw] Android Module Wizard -->
Upgrade code Templates [*.lpr, *.java]


Thank you!! I was wandering is there a way to get Device Model name ?
Like something similar to getDeviceID.

In Android Studio you can get it by calling android.os.Build.MODEL;

I tried to run AppTest1 on zte gf3 but it crashes when opening the
SDK...everything is set...

In General, make a new project created 2 modules with the main threw
the button on the switch to the second (for example AppTest1) -
everything turned out, but there is a but!:
when you press the button to close the second module... in fact it
needs to close and return to the first - but this is not happening...
the app just closes(

////Unit1
Code: Pascal  [Select][+][-]window.onload = function(){var x1 =
document.getElementById("main_content_section"); if (x1) { var x =
document.getElementsByClassName("geshi");for (var i = 0; i procedure
TAndroidModule1.jButton1Click(Sender: TObject);begin 
 if(AndroidModule2 = nil) then  begin   
gApp.CreateForm(TAndroidModule2, AndroidModule2);   
AndroidModule2.TryBacktrackOnClose:= True;   
//AndroidModule2.PromptOnBackKey:= False;   
AndroidModule2.Init(gApp);  end  else  begin    AndroidModule2.Show; 
end;end;                    /////Unit2
Code: Pascal  [Select][+][-]window.onload = function(){var x1 =
document.getElementById("main_content_section"); if (x1) { var x =
document.getElementsByClassName("geshi");for (var i = 0; i procedure
TAndroidModule2.jButton1Click(Sender: TObject);begin 
AndroidModule2.Close;end;

maybe I missed something?

Hi

Set ActivityMode := actRecyclable in the second form, at designtime or
in the code.

If possible, I suggest this could be the default value, except for the
first form.

Regards

Hi jmpessoa!
thanks for the reply!

After reinstalling from scratch on a new version... still the same
problems:
When you add to the form jView and when the app launches on the phone
an error occurs, as well checked with another phone - the same (((

PROJECT: https://yadi.sk/d/Q_RFE8hNroAc3

----------------------------------------------------------------------
jmpessoa · 2016-05-18 16:59

Hi ThreeCat!

Possible problems:

1.  jView1  require  jCanvas 
[sorry ... Lamw fail...]

2. NDK installed in  "D:\" 

3. About App "demos": Keep [templates] up to date!

Lazarus IDE menu "Tools"---> "[Lamw] Android Module Wizard" --->
"Upgrade Code Templates"
and more:  configure ".lpi" according to your system.

----------------------------------------------------------------------

Thank you!
Yes... the way it is! needed jCanvas

ThreeCat · 2016-05-19 08:40

The question is why this construction, when running on the phone
banging the application?(((
individually connection and transition to the second shape -
everything works

and why, if not to check for the existence of the second form if it is
available also the app crashes?


Code: Pascal  [Select][+][-]window.onload = function(){var x1 =
document.getElementById("main_content_section"); if (x1) { var x =
document.getElementsByClassName("geshi");for (var i = 0; i
con:=false;     try      tcp.ConnectAsync('192.168.43.132',7777);    
con:=true;     except        con:=false;     end; if con=true then 
begin   if(AndroidModule2 = nil) then      begin         
 gApp.CreateForm(TAndroidModule2, AndroidModule2);         
 AndroidModule2.TryBacktrackOnClose:= True;         
 //AndroidModule2.PromptOnBackKey:= False;         
 AndroidModule2.Init(gApp);       end else       begin       
AndroidModule2.Show;       end;   end else
self.ShowMessage('Connection problems!'); 
If you'll excuse a little too insistent demand from you information...
I think this is a big plus to the development of this project in terms
of testing, as part of my small knowledge

thank you for what you are working in this direction! (not all have
power iron that would work in Android Studio and not everyone likes
java)

this works...but still, those designs should be the same to work...
maybe the problem is in the ***time interval*** between connecting and
opening the second form?

ThreeCat · 2016-05-19 10:47

and still not clear! - How can there be when there is no server when
connecting to it the procedure is allegedly a connection with the
server was? - performed OnConnected.....

----------------------------------------------------------------------
jmpessoa · 2016-05-19 18:23

Hi ThreeCat!

in fact, the connection is asynchronous ["non-blocking"] so you need:

1. hanlde "OnConnected" to set "con:= True" and create new form.

2. handle  "OnMessagesReceived" to read the data received ...

There is an "AppTCPClientDemo1"  in "demos"  ...

Please try google:  "why should I use non-blocking or blocking
sockets?"

Ok. As soon as possible I will try to implement the blocking:
jTCPSocketClient1.Connect("","") mode.

suggestions:

1. After update the LAMW framework from github recompile [and install]
the packages ....

problems? try "more"--> "recompile clean"

2. if "old' project:  upgrade your project:

go to menu "Tools"--> [Lamw] Android Module Wizard --> Upgrade code
Templates

3. Try clear all your project:  menu "Run" --> Clean up and Build

----------------------------------------------------------------------

Thank you.
Clean up and Build - helped me.

with Self.SetKeepScreenOn() my application(API 16) show form and

without ScreenOn works fine


mayby need some rights in AndroidManifest.xml ?

ref. "version 0.6 - revision 45.2 - 21 May - 2016"

I have made a little change to jFomr methods signature:

    procedure SetKeepScreenOn(_value: boolean);
    procedure SetTurnScreenOn(_value: boolean);
    procedure SetAllowLockWhileScreenOn(_value: boolean);
    procedure SetShowWhenLocked(_value: boolean);

Please, update your system ["AndroidWidget.pas" and  "Controls.java"
in "...\java\"]

Now we can turn "On" and "Off" !!!

Quotemayby need some rights in AndroidManifest.xml ?

No.

Please, try from some "OnClick" to "On"  and "Off".

hi @jmpessoa, would you like to add screenshot of running demos? if
you can't, a photo (by camera) is okay.

Hello, jmpessoa.

After I upgraded LAMW to version 0.7 yesterday, now I always get the
message telling me to "Reload from disk" or "Ignore disk changes" when
I open my old project, even I've already reload and saved it.

Is it a new behavior set by intention? Or bug? Or something wrong with
my project file? Please see the attached image.

----------------------------------------------------------------------
jmpessoa · 2016-07-14 17:35

Hello Handoko!

Yes, "Is it a new [weird] behavior set by intention" to keeps up to
date the "java templates" code.... but we will try to avoid this
frequent call.

For now, please, always choose "Reload from disk"!

Thank you!

NOTE: You can see a "checkbox" in your image: check it!

----------------------------------------------------------------------
jmpessoa · 2016-07-17 16:39

Now, there is a little fix [lamwdesigner.pas], to avoid frequent
"Reload from

disk" when  the  project is re-open...

We need check this option when the dialog prompt:

Quote(x) Check for disk file changes via content rather than timestamp

NOTE: as always after the update, we need to re-install the package
[lazandroidwizardpack.lpk]

Hello @jmpessoa!

How can I maintain my copy of Controls.java instead of having it

thankyou!

No Problem. I will open this possibility....

Hello @jmpessoa!
Because of a new job   in a remote city   free time to spend in
developing was tending to zero and so I have disappeared for some
time.
My hope is to be more free now, to continue to contribute to your
great project!
github? Yes off course, when my testing on jSqlite and an improved
jListView are done I will post code on github for sure;-)
Thank you!

Hi jmpessoa,

I would like to ask for a feature.
I am using the jDatePickerDialog.
But when it shows, its always on the date of today.
It would be very nice to control the date when the popup shows !
Or am I missing something ?

Thanks in advance, Alfred.

----------------------------------------------------------------------
jmpessoa · 2016-09-08 18:59

Hi  Alfred,

I just Improved jDatePickerDialog and jTimePickerDialog

There is a Show method overloaded....

and an updated  "AppDateTimePicker  demo".

Code: Pascal  [Select][+][-]window.onload = function(){var x1 =
document.getElementById("main_content_section"); if (x1) { var x =
document.getElementsByClassName("geshi");for (var i = 0; i procedure
TAndroidModule1.jButton3Click(Sender: TObject);begin 
jTimePickerDialog1.Show(15, 15);  //exampleend; procedure
TAndroidModule1.jButton4Click(Sender: TObject);begin 
jDatePickerDialog1.Show(2015, 2, 3);  //exampleend; 
Thank you!

Hi jmpessoa,

Having another problem now (not related to the previous one).

I am trying to make a simple calendar by drawing some lines onto a
jDrawingView.
When this DrawingView is placed on a ScrollView, it will no longer be
visible.
However, when looking at the sources, this should be possible.
(I need to touch-scroll the DrawingView)

Can you help ?
Thanks.

----------------------------------------------------------------------
jmpessoa · 2016-09-10 05:02

Hi Alfred,

I got success with the following settings:

jScrollView1:
Quote    LayoutParamWidth = lpMatchParent
    LayoutParamHeight = lpHalfOfParent
    ScrollSize = 2000

jDrawingView1:
Quote      PosRelativeToParent = [rpCenterInParent]
      LayoutParamWidth = lpMatchParent
      LayoutParamHeight = lpSevenEighthOfParent

----------------------------------------------------------------------
DonAlfredo · 2016-09-10 05:20

Thanks.
And yes, that works ... but on my phone, the drawview does not fill
the scrollview for 100%.
So, I am still investigating.

In the meantime, pleae find attached a new addition for scrollview :
setFillViewport.

----------------------------------------------------------------------
jmpessoa · 2016-09-10 05:38

Thanks!

I will apply it!

----------------------------------------------------------------------
DonAlfredo · 2016-09-10 08:51

Some intermediate results.

I saw in your source that you put a relative layout inside the
scrollview.
I know that you have to do this to allow for more childs, while a
scrollview can only handle a single child.

In my case, I have a single child (very high drawingview) that has to
scroll with the scrollview.
IMHO, I think that we need a new basic scrollview without relative
layout for situations where there is only a single child !

----------------------------------------------------------------------
jmpessoa · 2016-09-12 18:25

Hi Renabor,

please go to menu "Run" --> "Clean up an Build" ...

The "pOnGLRenderer"  was droped...

Now we have:

 "pOnGLRenderer1" for jCanvasES1

and

 "pOnGLRenderer2" for jCanvasES2


NOTE:  if you are using "old" "Controls.java"  then you will need
upgrade
your project and then to do some "custom/hack" in the new code
architecture....

----------------------------------------------------------------------
DonAlfredo · 2016-09-14 06:07

@jmpessoa
Please find attached a new version of drawingview.
This version can be dropped on a FrameLayout (i.e. scrollview) as well
as on a RelativeLayout.

This drawing view itself is not that imortant however.
The included patch should be applied to all (visual) components.
It will allow all components to have a FrameLayout and RelativeLayout
parent !!

Please review. I hope you will apply this patch.
It makes all components more flexible !

Edit:
And, if you like it, you can easily add a linear layout too !!

----------------------------------------------------------------------
DonAlfredo · 2016-09-14 10:49

Added LinearLayout into patch !

----------------------------------------------------------------------
jmpessoa · 2016-09-14 18:45

@jmpessoa --> Feature request !

I would like to ask you for the possibility to add a canvas to
ListView.
At the moment, I am doing this (on a long viewlist):

Code: Java  [Select][+][-]window.onload = function(){var x1 =
document.getElementById("main_content_section"); if (x1) { var x =
document.getElementsByClassName("geshi");for (var i = 0; i
@Overridepublic  void onDraw( Canvas canvas) {               
super.onDraw(canvas);                View c = super.getChildAt(0);   
           int scrollposition = -c.getTop() +
super.getFirstVisiblePosition() *
(c.getHeight()+super.getDividerHeight());                Paint myPaint
= new Paint();                myPaint.setColor(Color.rgb(200, 0, 0)); 
              myPaint.setStrokeWidth(25);               
myPaint.setStyle(Paint.Style.STROKE);               
canvas.drawRect(100, 800 - scrollposition, 200, 900 - scrollposition,
myPaint);        } @Overrideprotected void dispatchDraw(Canvas canvas)
{                super.dispatchDraw(canvas);                View c =
super.getChildAt(0);                int scrollposition = -c.getTop() +
super.getFirstVisiblePosition() *
(c.getHeight()+super.getDividerHeight());                Paint myPaint
= new Paint();                myPaint.setColor(Color.rgb(0, 200, 0)); 
              myPaint.setStrokeWidth(25);               
myPaint.setStyle(Paint.Style.STROKE);               
canvas.drawRect(100, 2000 - scrollposition, 400, 2200-scrollposition,
myPaint);        } 
The former draws a square behind the ListView.
The latter draws a square before the ListView.
Both move along with scrolling, due to the scrollposition.

I would like to do this in an OnDraw and an OnDispatch of the listview
(drawing on the attached Canvas).
These two will also have to transport the scroll-position !
Is this possible ?

Thanks.

Hi all,

I have uploaded a brand new version of new_howto_install_by_renabor to
github.

Please notice that the old new_how_to_install_by_renabor has been
converted in several scripts!

Now all you have to do is run first script, "1-master-script.sh", that
will call other scripts in the right sequence.

At the end you will have:

1) /etc/fpc.cfg moved to /etc/fpc.cfg.bak and substituted by a symlink
2) ndk, sdk and lamw code placed in a new directory $HOME/Android
3) fpc and lazarus code placed in a new directory $HOME/bin/freepascal
4) a lot of scripts in $HOME/bin/freepascal

and a running compiled full suite of freepascal and lazarus ready to
crosscompile to android!

Version of software downloaded:

ndk            android-ndk-r11c-linux-x86_64
sdk            android-sdk_r24.4.1-linux
fpc (fixes)         3.0.1
lazarus          1.7

enjoy!

N.B. There is a bug in lamwdesigner.pas that make compiling
problematic.
please change line 58 as
Code: [Select]//    procedure OnDesignerModified(Sender: TObject{$If
lcl_fullversion>1060004}; {%H-}PropName: ShortString{$ENDIF});
procedure OnDesignerModified(Sender: TObject);
and line 1009
Code: [Select]//procedure
TAndroidWidgetMediator.OnDesignerModified(Sender: TObject{$If
lcl_fullversion>1060004}; {%H-}PropName: ShortString{$ENDIF});
procedure TAndroidWidgetMediator.OnDesignerModified(Sender: TObject);

Hi Alfred,

Something like that [??]:

added to "jListView.java"

Code: Java  [Select][+][-]window.onload = function(){var x1 =
document.getElementById("main_content_section"); if (x1) { var x =
document.getElementsByClassName("geshi");for (var i = 0; i        
@Override        protected void dispatchDraw(Canvas canvas) {        
   View c = super.getChildAt(0);        int scrollposition =
-c.getTop() + super.getFirstVisiblePosition() *
(c.getHeight()+super.getDividerHeight());                            
                //DO YOUR DRAWING ON UNDER THIS VIEWS CHILDREN       
       controls.pOnBeforedispatchDraw(canvas, scrollposition);
 //handle by pascal side                           
super.dispatchDraw(canvas);                        //DO YOUR DRAWING
ON TOP OF THIS VIEWS CHILDREN           
controls.pOnAfterdispatchDraw(canvas,scrollposition);        //handle
by pascal side            } 
So in pascal [event] side we could use the param "canvas" to set
"jCanvas"  and then draw some stuff... Something like that?

Code: Pascal  [Select][+][-]window.onload = function(){var x1 =
document.getElementById("main_content_section"); if (x1) { var x =
document.getElementsByClassName("geshi");for (var i = 0; i procedure
TAndroidModule1.jListView1BeforeDispatchDraw(Obj: TObject;  canvas:
JObject; scrollposition: integer);begin  jCanvas1.SetCanvas(canvas); 
jCanvas1.drawRect(100, 100, 400, 400);  // Yes!  \o/ \o/ \o/ \o/end; 
NOTE: I Got  scrollposition = 0 [always] ....

please help. thanks much 

And in dialog creating new project I see 2 options are armv7 + soft
armv7 +Fv3
So which one I should choose , and what are differences ?

Thanks

@Alfred,

Yes,  I implemented...
very soon I will update github repository....
[surely we have to put this feature in others/all components. So, I am
thinking/testing about the best strategy...]

@m4u:

The choice depends on how the cross-compiler was built ...
for Laz4Android "armv6"  and "armv7 + soft"   are good!

About "Access violation" I will do some  investigation...
until then, please, update and re-install the 03 LAMW packages...

i installed lamw, error "Access violation" still appears, but It's a
serious problem beacause I can build and run apk file well 
Hope you will fix this bug soon

As far as I know, it is not a good idea to use 64 bit JDK with 32 bit
SDK.
You did not mention OS and Lazarus revision you are using.
What exactly did you do to get Access Violation? What kind of project
did you choose in "Create a new project dialog"?
I cannot reproduce.

Hi Alfred!

OnBeforedispatchDraw and OnAfterdispatchDraw

is Done for jListView/jTextView/jEdtText/jButton

But NOTE: We need a dynamic [and not "harded" code]

LAMW_JAVA_NAMESPACE = 'org.lamw.common';

[Now we have legacy issues with "demos" and old projects!!!]

I wiil fix it!

----------------------------------------------------------------------
DonAlfredo · 2016-09-20 19:48

Thanks !

And , if you want to change the namespace of the common library, just
the same as the others, I am also perfectly fine with that ! My commit
was just a proposal, open for review. I could also do this for you !

Greetings.

----------------------------------------------------------------------
jmpessoa · 2016-09-20 20:11

OK, Please, do it!

Thank you!

----------------------------------------------------------------------
DonAlfredo · 2016-09-20 20:20

Tomorrow ... now its night-time in Europe ... :-)

----------------------------------------------------------------------
jmpessoa · 2016-09-20 22:12

Good dreams!

The task is done!

Thank  you!

NOTE: Just to simplify codification: "jCommons.java"

----------------------------------------------------------------------
DonAlfredo · 2016-09-21 09:23

Thanks again !

Btw, I have done a (rather bad in some places) commit to get some
things working, because the two new dispatch methods are not picked up
by the java-parser. Must be changed to something better.
On[]Dispatch its rather nice: a standard button with a bitmap is now
very easy.

----------------------------------------------------------------------
jmpessoa · 2016-09-21 19:01

Hi Alfred,

The naming:

Code: Java  [Select][+][-]window.onload = function(){var x1 =
document.getElementById("main_content_section"); if (x1) { var x =
document.getElementsByClassName("geshi");for (var i = 0; i public
native void pOnBeforeDispatchDraw(long pasobj, Canvas canvas, int
tag);public native void pOnAfterDispatchDraw(long pasobj, Canvas
canvas, int tag); 
is OK!

Thank you!

I tried to build simple GUI application with newest update. I was
successful until I put JButton on form. After that I can not build
APK.
Even, after I removed button I can not build apk any more. This is the
dump. It seems to me that there is an issue with JCommons, and I think
this is not only button issue. I think this is an issue with jTextView
also.

Hi dinmil

Please, update your project java stuff.... [close and reopen and try
"Run"]

jListView, jTextView, jEditText and jButton  are now in
"jCommons.java" compliance.

Try 1: "Run"--> "Clean up and Build"

Try 2. Des-Install an re-install all 03 lamw package:

.uninstall [amw_ide_tools.lpk]
.uninstall [lazandroidwizardpack.lpk]
.uninstall [tfpandroidbridge_pack.lpk]   // <--- uninstall at last!

RE- INSTALL:

          [tfpandroidbridge_pack.lpk] // <<-- install first
      [lazandroidwizardpack.lpk]
      [amw_ide_tools.lpk]

NOTE: In fact the update should be automatically...
please,  set "CanUpdateJavaTemplate=t"  in
"lazarus\config\JNIAndroidProject.ini"

----------------------------------------------------------------------
dinmil · 2016-09-30 08:35

Thanks for quick response.
Re installation of components and install didn't hep.
Cleanup and build did not help.

But settin "CanUpdateJavaTemplate=t"  in
"lazarus\config\JNIAndroidProject.ini" did the job.

I detect one more issue.
If you try to put jAutoTextView on form you will get access violation

Regards, Dinko

----------------------------------------------------------------------
jmpessoa · 2016-10-02 13:34

Hi dinmil,

About:
QuoteIf you try to put jAutoTextView on form you will get access
violation...

Fixed! Please, try/test again.

Thank you!

----------------------------------------------------------------------
dinmil · 2016-10-03 07:39

Just downloaded new version (zip file) from GIT HUB.
Removed old packages. Install new ones. Rebuild laz4android with clean
all option.
This Access Violation error still exists when you put JAutoTextView on
form.

Regards, Dinko

----------------------------------------------------------------------
jmpessoa · 2016-10-03 08:01

Please try this:

Code: Pascal  [Select][+][-]window.onload = function(){var x1 =
document.getElementById("main_content_section"); if (x1) { var x =
document.getElementsByClassName("geshi");for (var i = 0; i procedure
jAutoTextView.SetItems(AValue: TStrings);begin   if AValue <> nil then
    // <<---- added here....       FItems.Assign(AValue);end; 
NOTE 1: I do not have/detect any problem with jAutoTextView....

Note 2: You got A.V in design time?

----------------------------------------------------------------------
dinmil · 2016-10-03 08:35

I added this line into autocompletetextview.pas. Build and recompile
lazarus. Same situation (see Picture1)

Steps to reproduce.

I started new project Android GUI JNI MODULE LAMW.
After trying to add JAutoTextView one time, I choose OK in access
violation dialog, then I tried to add new one.
After that I got again access vilation and again choose OK. After that
2 JAutoTextView control shows on form.
Then I try to add third one. This time no problem and no access
violation.

Regards, Dinko

----------------------------------------------------------------------
jmpessoa · 2016-10-03 18:45

I will continue investigating .... repeating its sequence everything
goes well..

Code: Pascal  [Select][+][-]window.onload = function(){var x1 =
document.getElementById("main_content_section"); if (x1) { var x =
document.getElementsByClassName("geshi");for (var i = 0; i constructor
jAutoTextView.Create(AOwner: TComponent);begin  inherited
Create(AOwner);  
//.....................................................   FItems:=
TStringList.Create;  //potential error should be here [when
forgotten!]  
//.......................................................  end;

What Android SDK and Android theme settings do you use?

----------------------------------------------------------------------
dinmil · 2016-10-05 09:44

Android SDK Manager
Revision 25.2.2

Java is jdk1.8.0_102

Android Theme is DeviceDefault

Architecture ARMv6 (ARM v7 has the same behavior)

Regards, Dinko

----------------------------------------------------------------------
A.S. · 2016-10-05 18:39

Dinko, what Android SDK do you use? Not the version of the Android SDM
Manager, but what Android API? (Android 7.0 is API 24)

----------------------------------------------------------------------
dinmil · 2016-10-06 11:36

NdkPlatform is 21
MinSDKApi is 15
TargetSdkApi is 21 (tried all from 15, 21, 22, 23, 24 - no success,
only 19 is OK)

NdkPlatform is 15
MinSDKApi is 15
TargetSdkApi is 15 (tried 19=OK; 21=not OK)

NdkPlatform is 16, 17, 18, 19, 21
MinSDKApi is 15
TargetSdkApi is 19 (OK)

It seems that this error depends of combination Ndk and TargetSdk

Thanks for hint, Dinko

tfpandroidbridge_pack package has and_jni unit which similarly wraps
jni as jni unit does. Most of the unit contents are the same, only
jmpessoa add little additions, everything else should remain the same.
javaEnvRef is defined in customdrawnint unit, so you can't use that if
you use LAMW. LAWM equivalent of it is AndroidWidget.gApp.Jni.jEnv.

does lamw can use java api directly which just like use windows api
now?

----------------------------------------------------------------------
Thaddy · 2016-10-15 13:08

Yes, but the naming convention is different for fpc jvm. This is
clearly documented in the wiki.

----------------------------------------------------------------------
jmpessoa · 2016-10-15 19:01

Quotedoes lamw can use java api directly which just like use windows
api now?

LAMW is JNI based.

About JNI:
Quote.A specification/protocol for calling 'native' code from Java and
Java code from native applications ('Invocation API');

.An interface that allows Java to interact with code written in
another language:  The Java  code can invoke native methods;

.An interface that allows code written in another language to interact
with Java : The native code can instantiate Java objects and invoke
methods;

.JNI is about "Programming for the Java Virtual Machine";

.JNI is used  to interact with "native" code produced by system-level
language like C/C++ and Pascal/Object Pascal!

What is "ht2pas" and where can I find it?
Thank you!

Found! h2pas (not ht2pas) in fpc/bin !

----------------------------------------------------------------------
jmpessoa · 2016-11-25 16:16

QuoteFound! h2pas (not ht2pas) in fpc/bin !

Yes! Please, send me your linux "h2pas" [32 bits] or
put it in LAMW github [folder "ide_tools"].

NOTE 1: About "Import C Stuff".

Open a LAMW project,  go to LAMW "Import C Stuff". LAMW will
produce a library [*.so] and put it in the same folder of
"controls.so".
Then "h2pas" will produce a header conversion (*.pp) for each ".h" 
and put it in  folder   "..../jni".  Add the "*.pp" stuff to "uses"
section and.... have fun! 

NOTE 2. There is some issue/bug with  Android < 4.1 (already explained
here in the forum by @yury_sidorov). So stay with 4.1+.

I have put a link in ide_tools pointing to fpc_src_dir/bin/h2pas and I
think it is a better choice. What can succeed if version of h2pas

Automating the link creation could be a good solution in my advice

Hello everyone!

Can anyone tell me, why using block in LAMW:

   ...
finally
   ...
end;

doesn't work !? Any suggestions?

Hello   spiritt!

From demo "AppPascalLibExceptionHandlerDemo1"

procedure TAndroidModule1.jButton1Click(Sender: TObject);
var
  i: integer;
begin
  try
    i:= StrToInt('p');   // some erroneous code
  except

Ok, thank You for Your quick response:) However it doesn't work good
as well...

I put those lines below to mentioned project:

var
  tf: TextFile;
begin
    try
      AssignFile(tf, '\\');
      Append(tf);
      Writeln(tf, 'Test');
      // some erroneous code
      //    i:= StrToInt('p');
  except

  CloseFile(tf);
end;

...and as the result the app closed. Any other tip? Thank You in

Hello jmpessoa,

Lamw works great with fpc 3.0.0 and lazarus 1.6.2.
I use the last lamw 0.7.13 and it is a great work!

Some times ago a make a test with fpc 3.0.2 and lazarus 1.6.2 and
sample apps crash at startup on the android device.
I wait for the lazarus update, but with fpc 3.0.2 and the new lazarus
1.6.4 apps crash to at startup on the android device.

Is it normal, or maybe i make something wrong ?
Thank you!

----------------------------------------------------------------------
jmpessoa · 2017-03-05 14:24

Hello ketch!

1.Sometimes any modification or update can affect some [outdated] demo
application.... what app you have tested?

2. If you change your FPC revision then you need to do a
"Run"-->"Clean up and Build" before "[Lamw] "Build Android Apk and
Run"

----------------------------------------------------------------------
ketch · 2017-03-05 19:55

I have give a try to a lot of random sample and i dont remenber all.
I have fpc 3.0.0 and lazarus 1.6.2 reinstalled and can't retry now.
What i can say is that the AppActionBarTabDemo1 for example doesn't
work for me and i have make a clean new install after deleting old
directory (new fpc, new lazarus and new lamw)...
After executing exactly the same process for go back to fpc 3.0.0 and
lazarus 1.6.2 all works great.

----------------------------------------------------------------------
ketch · 2017-03-06 19:34

Hello jmpessoa,

today i make a new try with fpc 3.0.2 and lazarus 1.6.4 (total
reinstallation) and i dont find any working sample application.
I reinstall fpc 3.0.0 and keep lazarus 1.6.4 and the majority of
sample are working.
It seem that fpc 3.0.2 is the problem.
Is someone using the fpc version 3.0.2 and can confirm there is no
problem with this version.

Thank you.

No, I don't use jImageList. Anyway, if you mean the .create files,
where must I put them?
I copy the .native needed files in /lamwdesigner/, but what have I to
do with .create ?

You do not need handle the ".create" or ".native"  for the
components.... the form wizard  will take care of this...
What about create a new [test] project .... So you will understand the
new "smartdesigner" ..... and where is handled this stuff...

What I have understood is that the .native code is copied at the end
of Controls.java, when a new component is added to the form. No idea
of the purpose of .create file.
At the very first time of the new "smartdesign" era, Controls.java was
copied every time from lamw directory to project directory.
Now something is changed, because I guess that Controls.java is
recreated on-site, even if I have:

Code: [Select]CanUpdateJavaTemplate = "True".

Am I right?
thank you!

----------------------------------------------------------------------
jmpessoa · 2017-03-07 19:09

1. "Controls.java" + "Controls.native" + "jCommons.java"are default
for all initial project  [like an "empty" form]

2. Every [almost] component has a ".java" and a ".create" and
[optional]  a ".native" and [optional] etc ...

3. When you drag&drop a jComponent, over the form,  the
"jComponent.java" is inserted in your project ".../scr/...." and the
component ".create" and ".native"  are added at the end of
"Controls.java"

4.The "smartdesigner" use these information to generate a custom
".lpr" whenever a "save all" occur...

Good to know!
I have purged and reassembled Controls.java adhering to the new
design, but I get the same error:

Code: [Select]java.lang.UnsatisfiedLinkError: No implementation found
for int com.suevoz.borsa.Controls.pAppOnScreenStyle() (tried
Java_com_suevoz_borsa_Controls_pAppOnScreenStyle and
Java_com_suevoz_borsa_Controls_pAppOnScreenStyle__)

I think that something in an extra file is not updated, some file like
ControlsEvents.txt

in controls.lpr the method is defined as:
Code: [Select]{ Class:     com_suevoz_borsa_Controls
  Method:    pAppOnScreenStyle
  Signature: ()I }
function pAppOnScreenStyle(PEnv: PJNIEnv; this: JObject): JInt; cdecl;
begin
  Result := Java_Event_pAppOnScreenStyle(PEnv, this);
end;

is this correct?

Thank you!

----------------------------------------------------------------------
jmpessoa · 2017-03-08 22:09

Yes, this is correct!

You can see  in "Laz_And_Controls.pas"  //in line 1617

Code: Pascal  [Select][+][-]window.onload = function(){var x1 =
document.getElementById("main_content_section"); if (x1) { var x =
document.getElementsByClassName("geshi");for (var i = 0; i   // ------
----------------------------------------------------------------------
 //  Event Handler  : Java -> Pascal  // -----------------------------
-----------------------------------------------   // Activity Event 
Function  Java_Event_pAppOnScreenStyle         (env: PJNIEnv; this:

So I continue to think that these errors are due to some inconsistency
in the structure of your project...
Did you try some "new" project? what about?

I've just updated the repo and rebuild the lazarus. After that, I
observed that the jListView items overlaps with their image. I tried
then the ListView demo and I have the same effect.

Note: I use API 17.

Further, I'm wondering, is it possible to set subtext description for
each jListView item, something similar like subtitle from the action
bar?
I would like to express my appreciation for this great tool. :-)

----------------------------------------------------------------------
jmpessoa · 2017-05-17 01:39

Hello Luciantodor!

I tried some fix. Please update from github...

[Note: use the property TextAlign for  a not  overlaps layout]

Yes, it is!  just code a item as [ex]    "LAMW|Lazarus|Android" 
and use the properties TextSizeDecoreted, TextDecoreted and FontSize
... to get
the subtitles

Thank you!

----------------------------------------------------------------------
Lucian Todor · 2017-05-17 09:10

The text size decoration and it's delimiter really works. Thank you

lucabertoncini · 2017-07-16 09:17

Hello JMPessoa,
first of all lamw is a wonderful work!
I’m a freepascal developer, as some of us, I need to create an Android
App that interacts with my freepascal softwares. I’ve written the App
using Android Studio, but I’ve some problems to understand at all the
Android’s way of thinking. I’m evaluating lamw to rewrite the App with
this framework. There are 2 aspects I need to investigate.

First
The App executes some HTTP Post to a https server. I use
HttpsURLConnection object to post the data. The data I need to send is
a JSON-string (not a Name / Value). To do this with jHttpClient, I
need to access the equivalent of the output-stream as I do in Java. Is
there any way to achieve this?

Second
The App is connected by a TCP socket to a server and receives or sends
data in a binary way (I don’t use strings). Is it possible with
jTCPSocketClient?

I don’t have enough knowledge to modify or create jObjects. If you
have tutorials or documents that can explain how to create bridge
objects, I will be interested to study these documents and to try to
solve the problems by myself. Every help will be appreciated!

Thank you very much.

----------------------------------------------------------------------
jmpessoa · 2017-07-16 19:36

Hello, lucabertoncini!

Yes, jHttpClient and jTCPSocketClient can meet your requirements..
please go to
some app "demos" stuff ....

But, you can try, too, many pure freepascal FLC stuff [example: 
fphttpclient ...]

If you need improve [or create] a component I can help you....

----------------------------------------------------------------------
lucabertoncini · 2017-07-17 11:40

Hi JMPessoa,
thanks for your time.
I took a look at the demos to try to understand how to use this
interesting code.
If I’m right, to be able to post a JSON string with jHTTPClient I
should write a procedure similar to jHTTPClient_AddValueForPost2 but
with only a single parameter.


Something like

procedure jHTTPClient_AddStringForPost(env: PJNIEnv; _jHTTPClient:
JObject; _AString: string);
  var
  jParams: array[0..0] of jValue;
  jMethod: jMethodID = nil;
  jCls: jClass = nil;
begin
  jParams[0].l := env^.NewStringUTF(env, PChar(_AString));
  jCls := env^.GetObjectClass(env, _jHTTPClient);
  jMethod := env^.GetMethodID(env, jCls, 'AddStringForPost',
'(Ljava/lang/String;)V');
  env^.CallVoidMethodA(env, _jHTTPClient, jMethod, @jParams);
  env^.DeleteLocalRef(env, jParams[0].l);
  env^.DeleteLocalRef(env, jCls);
end;

What about an https connection? In Android I need to use a different
object  HttpsURLConnection.
In this case I need to change the function jHttpClient_Post with this:
jMethod := env^.GetMethodID(env, jCls, 'Post',
'(Ljava/net/HttpsURLConnection;)Ljava/lang/String;');

These are the two test I'll do in the next days. Do you think it is
the right way?

----------------------------------------------------------------------
lucabertoncini · 2017-07-17 15:00

I've found this tutorial.

http://www.pacifier.com/~mmead/jni/delphi/JEDI/DOCS/delphi-jni-1.html

Everything I wrote in the previous post was wrong!

I'll try the way of using fphttpclient and fpsock library.

Thank you!

----------------------------------------------------------------------
jmpessoa · 2017-07-17 16:16

Quotehttp://www.pacifier.com/~mmead/jni/delphi/JEDI/DOCS/delphi-
jni-1.html

Yes, a great "core" tutorial....

But LAMW code architecture is much easier!

First we write a java class to wrapper some android API..
Example:  jHttpClient is a wrapper for android HttpsURLConnection...
See the demos "AppHttpClientDemo1" and AppHttpClientDemo2
.....AppHttpClientCookiesDemo1, etc...
You can see the java stuff in folder "YourProject/scr/........."

Note: To use fpc FCL core, you often need to copy the source code to
you project
"jni"  folder ....
Example: To use  "fphttpclient" copy "fphttpclient.pp",  "httpdefs.pp"
and "httpprotocol.pp" to you project "jni" folder

But, I think you can try first the LAMW jComponents!

----------------------------------------------------------------------
lucabertoncini · 2017-07-17 16:23

Ok, in the next days I'll go deeper. Thanks!

Dear specialists,
I Am new user on this forum. My name is Janusz Chmiel. I Am visually
impaired user with no sight at all. I would like to express my deepest
possible appreciation to all of you, who have developed so amazing
component for Lazarus. I AM able to use all of yours provided demo
examples while using it with Talkback screen reader. I Am very very
glad, that you have enabled visually impaired to use compiled Android
apps created by using yours component. I have only one programmers
plea to you. When programmer add background special command, so app
can run at background. Does running program allocate so much RAM, that
Android memory management can start to automatically kill some
processes? I AM afraid, that if I will listen live Internet radio and
app will run at The background, that app will automatically allocate
so much RAM, that my favourite Talkback screen reader would be
automatically terminated by Android memory management algorithms. Or I
do not have to have fair because of it. Because resulting app is
optimized also because of RAM allocations? Sure, I know, that it
depend also on programming techniques which will be used by Pascal
programmer. Really, very well done. I have never thought, that i would
be able to find so perfect freeware solution.

----------------------------------------------------------------------

Dear specialists,
Would somebody of us write me commands, which I had to add to have
wakelock set to The walue, so background tasks will be working even
when I turn The phone screen off? If I will place such commands to The
unit1.pas and external .so library will be called from here. Will be
wakelock applied also for internal machine code of native C .so
library which will be called? I Am afraid, that Android would suspend
threads from native external library. Or i do not have to think so? So
please, which lines and which commands should be part of The .pas
source code? Thank you very much.

If i create new project with 2 forms, form1 has 1 jbutton, when I
create second form, IDE will crash
I dont know why

If i dont use jbutton and use jimgbutton instead, everything is ok

I tried some cases
I have 2 forms, if form1 has
jbutton,jedittext,jlabel,jradiobutton,jcheck , the form2 cant have
those because IDE will crash
I concluded I just can put those components on 1 form, other forms
have them will cause IDE crash

Hi All,

I've been using LAMW now for nearly a month and am very impressed with
it. It's obviously taken a huge amount of work to get it to where it
is now. Congratulations and thanks.

However I do have a problem  (isn't there always one  ). I'm writing a
database App using jSQLDataaccess and jSQLCursor with jGridview to
display my data. Unfortunately there isn't a jDBGridView (I know it
would be a big task but much appreciated) so I'm stringing these
together on the native code side like so:

for R := 0 to sqlCursor.RowCount-1 do
begin
  for C := 0 to sqlCursor.ColCount-1 do
    Gridview.Cells(C, R) := sqlCursor.GetValueAsString(c);
  sqlCursor.MoveToNext;
end;

and here come the issue, I can't display all my records in the
Gridview without running out of local reference space in the JNI.  I
trace this to the JNI function 'jSqliteCursor_GetValueAsString' in
'And_jni_Bridge.pas' which uses GetStringUTFChars to obtain the field
value. It returns to my function without ever calling
ReleaseStringUTFChars so the references accumulate in the JNI and
eventually cause the App to crash. The JNI spec recommends always to
call ReleaseStringUTFChars, irrespective of the value of the isCopy
parameter to GetStringUTFChars so that its local reference stack can
be cleaned by the GC process.  I've tried several solutions to make a
copy of the string value and then call ReleaseStringUTFChars but they
all fail with the same error.  Does anybody have a solution?

This mechanism is used in several places in LAMW so could potentially
cause problems in other situations too.

Your responses awaited with eagerness

Cheers

to sqlCursor.RowCount -1  do   // <<-----try change herebegin    for C
:= 0 to sqlCursor.ColCount - 1 do   // <<-----try change here   
begin    .....    end;end

Whoops, that was a silly mistake in my pseudo-code (now edited). What
you wrote was what I was actually doing in the App, so the problem
remains.

Cheers

----------------------------------------------------------------------
jmpessoa · 2018-02-02 15:07

Ok. Write here you rowCount and colCount ....
[maybe a gridview capacity ???]

----------------------------------------------------------------------
Martin Lowry · 2018-02-02 16:32

Hi jmpessoa,

Quite a small table really for a DB,  120 rows by 18 columns, all
fields as strings.  Would that be too big for a gridview?

What really got me posting was the logcat output: see attached.

Cheers

Dear jmpessoa,
  I'm using LAMW for quit some time now, and I would like to thank you
and please improve it more and keep it upto datey.
I would like to upload an image file to my http server using
httpclient post, Can you help me.
jHttpClient looks like doesn't support file upload, please can you
provide me with an example code to upload file or image from the
android mobile to http server
Many thanks,
Horas

----------------------------------------------------------------------
jmpessoa · 2018-03-11 02:18

Hello, Horas!

I will try improve jHttpClient!

Thank you!

PS.

As a side note: you can try pure fpc stuff...
put this units [from: "\lazarus\fpc\3.1.1\source\packages\fcl-
web\src\base"]
fphttpclient.pp
httpdefs.pp
httpprotocol.pp

 in your project  "....\jni"  folder:

The "GET" sample is here:

Code: Pascal  [Select][+][-]window.onload = function(){var x1 =
document.getElementById("main_content_section"); if (x1) { var x =
document.getElementsByClassName("geshi");for (var i = 0; i unit
unit1; {$mode delphi} interface uses  Classes, SysUtils,
AndroidWidget, Laz_And_Controls, fphttpclient, httpdefs, 
httpprotocol; type   { TAndroidModule1 }   TAndroidModule1 =
class(jForm)    jButton1: jButton;    procedure jButton1Click(Sender:
TObject);  private    {private declarations}  public    {public
declarations}  end; var  AndroidModule1:
TAndroidModule1; implementation {$R *.lfm}   { TAndroidModule1
} procedure TAndroidModule1.jButton1Click(Sender: TObject);var  resp:
string;begin     With TFPHTTPClient.Create(Nil) do      try       
 resp:= Get('http://....');      finally        Free;      end;     
ShowMessage(resp);end;

Martin Lowry · 2018-03-23 15:43

Hi,

I was hoping to use Activity.onNewIntent to communicate new data to a
single_instance task but see that the event is not surfaced in jForm
even though all the necessary code is present in App.java,
Controls.java and AndroidWidget.pas.  Will it work if I just un-
comment the appropriate lines?

Cheers

Hello,

writing for the first time here, so thanks a lot for the LAMW tools,
the Lazarus + LAMW approach to Android development seems rocket-fast
compared to the alternatives. Also I like the LAMW widget model, it
seems to me more straightforward than the LCL applied to mobile
devices.

I need your LAMW experts' help though. As I tried creation of the
wrappers around an Android widget, I used the Smart LAMW Designer tool
(my config is Laz4android 1.8/ FPC 3.0.4 on Windows 10 x64, Android
platform 19, Android SDK from tools_r25.2.5-windows):
Tools > [Lamw] Android Module Wizard > New jComponent Createfor my
tests I pasted the code of
\lazandroidmodulewizard\java\lamwdesigner\jToggleButton.java in the
Java tabright-clicked > Write  [Draft] Pascal jVisualControl
Interfaceafter a couple of warnings, I got some code in the Pascal tab

My question is about these fragments in the generated Pascal code:
Code: Pascal  [Select][+][-]window.onload = function(){var x1 =
document.getElementById("main_content_section"); if (x1) { var x =
document.getElementsByClassName("geshi");for (var i = 0; i unit
lass;class = class(jVisualControl)constructor class.Create(AOwner:
TComponent);procedure class_SetBackgroundDrawable(env: PJNIEnv;
_class: JObject; _imageIdentifier: string);   
Is that possible to somehow configure the tool to generate something
like this instead:
Code: Pascal  [Select][+][-]window.onload = function(){var x1 =
document.getElementById("main_content_section"); if (x1) { var x =
document.getElementsByClassName("geshi");for (var i = 0; i unit
togglebutton;jToggleButton = class(jVisualControl)constructor
jToggleButton.Create(AOwner: TComponent);procedure
jToggleButton_SetBackgroundDrawable(env: PJNIEnv; _class: JObject;
_imageIdentifier: string);   
I understand, that jToggleButton is already there, but I saw the same
behavior for any Java class name.

Thank you for your help,
Sergei

----------------------------------------------------------------------
jmpessoa · 2018-03-24 16:05

Hi, Sergei!

Quoteclass = class(jVisualControl)

Here we got a bug!!!

Please change "public class jToggleButton"  to  "class jToggleButton"
before
right-clicked > Write  [Draft] Pascal jVisualControl Interface...

----------------------------------------------------------------------
Sergei · 2018-03-24 16:48

Thank you so much, the workaround works here!

----------------------------------------------------------------------
Sergei · 2018-03-26 10:18

Hi Jose, experts,

is that possible to create a LAMW wrapper for a 3-rd party widget,
indirectly subclassing Android SDK widgets?

I am trying to connect the MaskEditText widget
(https://github.com/santalu/mask-edittext). The widget is inheriting
from android.support.v7.widget.AppCompatEditText and sits in its
com.santalu.maskedittext package. I tried to create a directory
structure for that package in several places of the source tree, but
to no avail. Most likely modifications to the Gradle build are
necessary too.

Also, if a widget had dependencies to jars/Gradle artifacts in outside
repos, how can I configure tfpandroidbridge_pack.lpk or my project?

Any pointers are highly appreciated.
Sergei

Many thanks for sharing the 0.8 preview, seems like a huge amount of
work has been done.

Installation went smoothly, but I was not able to use the packages as
my android-26 config was not recognized in the new project form.

I would love to try tackling the code, can you give me some light on
how to debug the 3 *.lpk packages in the most efficient way? What
strategy are you using? Is there any integration test somewhere to
initialize and run the forms?

----------------------------------------------------------------------
jmpessoa · 2018-03-28 21:15

Quotebut I was not able to use the packages as my android-26 config
was not recognized in the new project form.

You can look in "...sdk\build-tools" if you lost the "26.x.x" 
folder...

You can try  "uformworkspace.pas"  code [LAMW folder "android_wizard"]
... look for
method "GetMaxSdkPlatform" in line:

Code: Pascal  [Select][+][-]window.onload = function(){var x1 =
document.getElementById("main_content_section"); if (x1) { var x =
document.getElementsByClassName("geshi");for (var i = 0; i if
HasBuildTools(intAux, outBuildTool) then  Result:= intAux;

Some things to check and try:
1) Make sure you have gradle installed according to the instructions
(see section 3.4. Environment variables)
2) Edit gradle_local_build.sh to correct errors. (possibly all you
need is one line:  gradle clean build --info)
3) Give gradle_local_build.sh execute permission
4) Try running gradle_local_build.sh from a command line.

Hello, Mr-Highball!

Sorry...  but  LAMW  do not support  custom user defined service, yet
...

[The LAMW 0.8    development focus  was "material design" and "support
libraries" ....]

Now,  I will can try some approach to support "custom user defined
service" ....

Until there, if you have some need for a specific service, I can try
help you!

Thank you!

Hi everybogy.

I have questions about jTCPSocketClient component.

When I try asyncConnect and sendmessage it is work perfect! but if I
then do CloseConnection, and then again asyncConnect, it connected,
but sendmessage didn't work (

How to create a new jTCPSocketClient component in run time?

I tryed :
clientsocket := jTCPSocketClient.Create(gApp);
clientsocket.Init(gApp); 

and

clientsocket := jTCPSocketClient.Create(Self);
clientsocket.Init(gApp); 

but both crashed in clientsocket.Init(gApp);

Thank you.

Sorry I can't help you with jTCPSocketClient.  If your application can
use synchronous / blocking communication calls, another option is to
use Synapse (see also here).  It works with Android with a small
modification to one file (see bug report here).

Code: Pascal  [Select][+][-]window.onload = function(){var x1 =
document.getElementById("main_content_section"); if (x1) { var x =
document.getElementsByClassName("geshi");for (var i = 0; i uses
BlckSock;     TCPBlockSocket := TTCPBlockSocket.Create;

Does using old android sdk manager ( like r24/r25 ) affect to created
app ?
Sometimes I see my app run well on my phone (android 5.0) but on
higher it crashes ( if the app implemented internet connection
components ) ( although the target api is android 6.0/7.0)

It's possible do this code:

installIntent.setDataAndType(Uri.parse("file:///path_to.apk"),
                    "application/vnd.android.package-archive");

on pascal? May be with jIntentManager, but how?

if necessary I can [try] improve the jIntentManager component!

Is there any way how to install(update)  the same application what is
running, from apk file (downloaded erly)? I mean programmatically.


If I do
jIntentManager1.SetAction('android.intent.action.VIEW');
jIntentManager1.SetDataUri(jIntentManager1.ParseUri('file:///path_to_a
pk'));
jIntentManager1.StartActivity();

I got mesage "Cannot display PDF"

P.S.
It seems I found where the problem is. The problem is that
jIntentManager1 have two procedures "SetDataUri" and "SetMimeType",
but don't have procedure (java  method) SetDataAndType.
More info is here: https://stackoverflow.com/questions/13719471/why-

2. Hidden project options in controls.lpi, <CustomData />, project
can't migrate to other system.

3.  src\org\lamw\myproject\*.java not re-created on build. For
example, I copy some jForm (lfm + pas) from other project, and get
runtime error:

QuoteI/dalvikvm(21351): java.lang.NoSuchMethodError: no method with
name='jTimer_Create' signature='(J)Ljava/lang/Object;' in class
Lorg/lamw/myproject/Controls;
4. Lack of properties for related controls (widgets). For example,
setting jForm.ActionBarTitle to abtTextAsTitle cause runtime error,
that ActionBar not found. And there no property to assign ActionBar or
it's name/id. Same for other related controls - AppBarLayout,
TabLayout, ViewPager...

5. Context menu - Change parent is not active, parent can be changed
only by editing .lfm

jLocation crashes on Android 6.0 and higher
I tested, it works well on Android 5.x and below
Or because i use ndk r10e ?

----------------------------------------------------------------------
jmpessoa · 2018-05-30 22:55

Hi m4u!

I think your system need some "cleanup"!!!

1) you can try  "cleanup" your app project: Open your project and then

Lazarus IDE: "Run" --> "Clean up and Build..."

2) if not working [yet],  you can try  "cleanup" the LAMW packages:

Lazarus IDE: "Packages" --> "Open Package File (.lpk)"
 
Select some/all LAWM package then:

--> "More" --> "Recompile Clean"     

and

--> "Use" --> "Install"

and then (1) again..

Hello jmpessoa

Thanks for excellent work.

There's a little problem in  Lawn version 0.8.

For Android 6 and higher  after install app need to manually enable
the permissions in system  or use exceptions in code.

example for white/read permissions

Code: Pascal  [Select][+][-]window.onload = function(){var x1 =
document.getElementById("main_content_section"); if (x1) { var x =
document.getElementsByClassName("geshi");for (var i = 0; i  try //code
...  stringlist_text.SaveToFile(Self.GetEnvironmentDirectoryPath(dirSd
Card) + 'mydir' + '/' +'myfile.txt';  //code... except         
showmessage('no write/read permission');      end;     

Otherwise, the application will crash.

I have everything works on the following settings:

Windows-x86,
Lazarus Android Module Wizard 0.8.1,
laz4android 1.8, FPC  3.0.4,
Java JDK 1.8 update 171,
Android SDK Build-Tools 27.0.3
Android NDK r17,
min SDK version 15,
target SDK version 27, 
Ant 1.10.3. 

best regards

rx3.fireproof

p.s.
to manually change settings for other builds it's hard

When i use the button, Take photo. The APP stop.

I have using Android 6.0 ( API 23 ), SDK 28.0.0,  jdk1.8.0_171 and i
execute it in Phone with Android 8.0.

I have ones questions.
What´s ANT and GRADLE?

What's the minimum version to execute the App make with the tool?

----------------------------------------------------------------------
jmpessoa · 2018-06-26 00:04

Hello Almir!

QuoteWhat´s ANT and GRADLE?

Ant and Gradle are builder-systems to compile and "build" android APK

You need Gradle  when select "AppCompat" themes and "Android Bridges
Support" palete/components...

but for simple/default projects Ant is ok...

Hi sameer!

Look for "jDBListView.java" in  LAMW folder "......\java\lamwdesigner"

if  the file exists then delete  the jDBListView componet from Form
designer
and do  "run->build"

Now put again the jDBListView componet  in the form...

jmpessoa,

Stability is very important and I figured it is probably best to use
the same/closest possible version to what you are working with.
But I am confused about which SDK and build/tools/platform-
tools/build-tools  version to use with LAMW.

http://wiki.lazarus.freepascal.org/LAMW says that R24.4.1.  But SDK
manager does not recognize this version and the downloaded zip file
does not seem to contain all files needed to work out of the box.

Is there any risk using a more recent NDK?

----------------------------------------------------------------------
jmpessoa · 2018-08-27 15:57

Hi,  CC!

1) For not "AppCompat" themes  you can use/target any recent API ....
[warning: the R24.4.1 is the last that support "ant" builder]   ...
Recommended: target 21 or 22 [not run permission is required !!!]

2) Yes, R24.4.1  [or any...] is not "complete" out of box...

[from "LAMW getting started.txt"]
                1)after unpacked [R24.4.1 or any...], open a terminal
and go to "sdk/tools"  folder
      2)run  cmd "android sdk" to open a GUI "SDK Manager"
      3)check "Android SDK Tools"
      4)check "Android SDK Platform-Tools"

      5)check "Android SDK Build-Tools 25.0.3" [need for "gradle"
builder] 

      5.1)check  "Android SDK Build-Tools 26.0.2"  [need for "gradle"
builder]

      6)go to "Android 7.1.1 (API 25)" and check  "SDK Platform" [need
for "AppCompat" themes and "gradle" builder]

      7)go to "Extras" and check:
            "Android Support Repository"            
            "Android Support Library"            
            "Google USB Drive"

3) For "AppCompat" themes the only "recommended"  for LAMW:

"Android SDK Build-Tools 25.0.3" [need by old "gradle" plugin] 
"Android SDK Build-Tools 26.0.2"  [need by 3.0.1  "gradle" plugin ...]

Hello

I'm using the jTCPSocketClient component in an android project and
need to send a 1024 bytes sequence, but it can not send bytes, only
string by the jTCPSocketClient.SendMessage command.
It would have a way to send bytes instead of text.

Thank you.

----------------------------------------------------------------------
Handoko · 2018-08-30 12:29

You can write you own functions for converting bytes to text string
and the opposite.

I ever read the discussion about it but I forgot where to find it.

----------------------------------------------------------------------
abssistemas · 2018-08-30 12:50

does not work because the SendMessage command does not send bytes that
are not valid characters, such as '$00', '$0A'.

----------------------------------------------------------------------
Handoko · 2018-08-30 12:54

Not I didn't mean like that.

You convert a char $0A to become a string that contains 2 characters
'0A'.

This trick is useful for transmitting binary data as human-readable
text, read more:
https://en.wikipedia.org/wiki/Base64

----------------------------------------------------------------------
abssistemas · 2018-08-30 13:03

I understood, but then I would have to convert inside my firmware
again, I did not want that.
The bluetoothclientsocket.pas file sends text and bytes, with the
WriteMessage and write method respectively. Would you be able to
implement the write method in the tcpsocketclient.pas file?

----------------------------------------------------------------------
Handoko · 2018-08-30 13:27

It doesn't seem hard to implement but unfortunately I'm not familiar
with network programming.

You can make a feature request. But if you need the feature to be
implemented quickly, you can consider to create a bounty for it:

normally, but soon after sending the bytes the connection is lost, and
I do not get any more data through the socket. I have to connect
again. The jTCPSocketClient1.SendMessage method remains connected
without problems.

"OnBytesReceive" does not work does not receive anything.
Here's my code:


type

  { TAndroidModuleMaps }

  TAndroidModuleMaps = class(jForm)
    procedure jButton2Click(Sender: TObject);
    procedure jTCPSocketClient1Connected(Sender: TObject);
    procedure jTCPSocketClient1MessagesReceived(Sender: TObject;
      messagesReceived: array of string);
    procedure jTCPSocketClient1BytesReceived(Sender: TObject;
      var bytesReceived: TDynArrayOfJByte);


procedure TAndroidModuleMaps.jButton2Click(Sender: TObject);
begin
  //NEW!!! Prepare to "Send" and "Receive"  bytes
  jTCPSocketClient1.SetDataTransferMode(dtmByte);

  jTCPSocketClient1.ConnectAsync('192.168.15.5',1024);

end;

procedure TAndroidModuleMaps.jTCPSocketClient1MessagesReceived(Sender:
TObject;
  messagesReceived: array of string);
begin
  //aqui funciona
  ShowMessage('Recebido string');
end;


procedure TAndroidModuleMaps.jTCPSocketClient1BytesReceived(Sender:
TObject;
  var bytesReceived: TDynArrayOfJByte);
begin
  //aqui não funciona
   ShowMessage('Recebido bytes');
end;

Hi  abssistemas!

Attached is a new java template ..... 

Put this [unzipded!] "jTCPSocketClient .java" file in the  folder 
"..... \java\lamwdesigner" of the LAMW framework ...

re-open your project and make a new build .... etc ....

I just inserted some "debug" tags...

Please,  keep this:

jTCPSocketClient1.SetDataTransferMode(dtmByte);
jTCPSocketClient1.ConnectAsync(....);

and test the "SendBytes"  ......

for debug,  "OnBytesReceive"  will try report  only 2  jbytes ....

"0" and "0"

OR

"-1" and "-1"

OR

of course, the bytes reported by your system...

You can report your test here...

Thank you!

With this line

jTCPSocketClient1.SetDataTransferMode(dtmByte);

It did not send, but without it is sending only string

Hi jmpessoa,

Is it missing to create the TOnBytesReceived event in my project?
The jTCPSocketClient component does not have the TOnBytesReceived
event on it, only the TOnConnected and TOnMessagesReceived events.
I'm declaring it right, see what I've done:

type

  { TAndroidModuleMaps }
    procedure jButton2Click(Sender: TObject);
    procedure jTCPSocketClient1BytesReceived(Sender: TObject;
      var bytesReceived: TDynArrayOfJByte);


procedure TAndroidModuleMaps.jButton2Click(Sender: TObject);
begin
  //NEW!!! Prepare to "Send" and "Receive"  bytes
  jTCPSocketClient1.SetDataTransferMode(dtmByte);
  jTCPSocketClient1.ConnectAsync('192.168.15.5',1024);
end;

procedure TAndroidModuleMaps.jTCPSocketClient1BytesReceived(Sender:
TObject;
  var bytesReceived: TDynArrayOfJByte);
begin
  //is not showing this message
   ShowMessage('Received bytes');
end;

With the lamw update o  jTCPSocketClient worked perfectly,
congratulations.

I'm having a new problem with the jActionBarTab component.

It is not working on android oreo 8.0, closes the application. In sdk
target 22 it works, but  26 or 27 does not.

If I run on android 7 or smaller runs smoothly.

as is attached one.

Thank you in advance.

Hi, bobkos!

jListView has some default tokens  delimiters for line text
formatation purposes...

but, you can change the defaults....

procedure TAndroidModule1.AndroidModule1JNIPrompt(Sender: TObject);
begin
  jListView1.SetLeftDelimiter('{');
  jListView1.SetRightDelimiter('}');;
end;

The code is 2 years old. I believe last year google maps started to
lose its free (as in no API key needed) service. Today even your free
calls require an API key, with limited number of calls per day (not
really remember how many, probably 1000). The code definitely needs an
update.

Adromir · 2018-12-30 18:13

Thanks I got it Running with that. Still got an Access- Violation when
i opened and importet a Project, but still worked when i ignored that.
Maybe a few suggestions:

1. Could the Install Cross Compile Wizard save the Location of the
Source? I mean its not needed often, but a bit annoying when you start
to setup your environment
And another Hint maybe for the Setupinstructions: Apparently Gradle
sometimes need a properly set JAVA_HOME variable. Compiling didn't
work on my system at the beginning (WIN10), because I also had JDK10
installed
2. I believe FPC Trunk now supports a new range of Android Cross
Compilers. Are you planning to support them?
3. As the Target of the Project is set up through the Wizard, is there
any way to change that? Like switching from arm to x86?

I solved this problem by changing the background color of
AndroidModule2. So it turns out that actually AndroidModule2 has been
displayed only because the background color is the same as
AndroidModule1 so it's not visible.

Go to your project folder ".....\res\values-v21\styles.xml"

change this line:

Btw, I have one question. Hehe...

Because the error show require to accept the license, but there's no
license agreement window is there.

----------------------------------------------------------------------
jmpessoa · 2019-08-22 04:35

No. That is a gradle [process] report....

What this "error" does mean?   [Gradle, won't be able to install it,
because it depends on "accept license"  event...]

So, you need [manually] install the required sdk/platform
"android-28"  [and sdk/built-tools"28.0.3"].

Just execute the GUI "SDK Manager" (aka "sdk/tool/android.bat")
[and there you wil need  "accept license" to update your system]

I do it already, but all of my projects still stopped working. I even
modifying old build.gradle file, because it won't build anymore.

I think, there are major causes: I try to add easel's panel into the
main form after the splash screen, and I think I can't init any form
in the JNI_Promt event anymore.\

I'm using AppCompatNoActionbar, btw.

Code: Pascal  [Select][+][-]window.onload = function(){var x1 =
document.getElementById("main_content_section"); if (x1) { var x =
document.getElementsByClassName("geshi");for (var i = 0; i procedure
TViewSplash.tmrStartupTimer(Sender: TObject);begin  if clStartup < 11
then  begin     clStartup += 1;     pbStartup.Max := 10;   
 pbStartup.Progress := clStartup;  end  else  begin    clStartup :=
0;    tmrStartup.Enabled := False;    gApp.CreateForm(TMainControl,
MainControl);    MainControl.InitShowing(gApp);  end;end;

Code: Pascal  [Select][+][-]window.onload = function(){var x1 =
document.getElementById("main_content_section"); if (x1) { var x =
document.getElementsByClassName("geshi");for (var i = 0; i      
procedure TAndroidModule1.jButton1Click(Sender: TObject);      begin 
        if AndroidModule2 = nil then           begin               
gApp.CreateForm(TAndroidModule2, AndroidModule2);               
AndroidModule2.InitShowing(gApp);                             // <--
Fixed!!!           end              else           begin             
 AndroidModule2.Show();           end;      end;

I think that's doesn't what I mean. But, yeah. The demo doesn't even
work too.

----------------------------------------------------------------------
jmpessoa · 2019-08-22 05:22

You code:
Quote ViewLogin.Init(gApp);     

What about:  ViewLogin.InitShowing(gApp); ??

I mean, it's actEasel... 

Code: Pascal  [Select][+][-]window.onload = function(){var x1 =
document.getElementById("main_content_section"); if (x1) { var x =
document.getElementsByClassName("geshi");for (var i = 0; i if not
Assigned(ViewLogin) then  begin    gApp.CreateForm(TViewLogin,
ViewLogin);    ViewLogin.Init(gApp); // <- Don't show actEasel
forms...    ViewLogin.pnView.SetViewParent(pnView); // <- here you
are.  end; 
Btw, actEasel on "AppCompatNavigationDrawerDemo1" have the same
problem too.

----------------------------------------------------------------------
jmpessoa · 2019-08-22 05:37

hummmm... and do you need:

Code: Pascal  [Select][+][-]window.onload = function(){var x1 =
document.getElementById("main_content_section"); if (x1) { var x =
document.getElementsByClassName("geshi");for (var i = 0; i procedure
TViewLogin.ViewLoginJNIPrompt(Sender: TObject);begin 
jsFloatingButton1.SetPressedRippleColor(colbrCyan); 
jsFloatingButton1.ImageIdentifier:= 'ic_gear_white_36dp'; 
edUsername.Text := '';  edPassword.Text := '';end; 
after  "ViewLogin.Init(gApp)" ???

No, it's just a sample what I'm doing in TViewLogin's JNI_Prompt.
Because of that design time problem, I am tired to clear
edUsername.Text every time I open project so I add that into
JNI_Promt. After removing them it's still same, I can't init
TViewLogin or any actEasel forms.

----------------------------------------------------------------------
AFFRIZA 亜風実 · 2019-08-22 05:55

Btw, I revert into LAMW from 02 August 2019, and actEasel... It works
again.

I found a bug!   [life time: a day ago....]

Please,  update "jEditText.java" template from the git!

[folder "................\android_wizard\smartdesigner\java"]

----------------------------------------------------------------------
AFFRIZA 亜風実 · 2019-08-22 06:25

Thank you... 

I will test it at night, I'll report it later.

----------------------------------------------------------------------
AFFRIZA 亜風実 · 2019-08-22 09:16

I just tested. Seems the actEasel in the
"AppCompatNavigationDrawerDemo1" still doesn't work. I don't know why.
Any clues?

Here,  I can run "AppCompatNavigationDrawerDemo1" [and
"AppAnimationDemo1"]  on
all my  real  devices..... Android 4.3, Android 5.0.1 and  Android

Maybe, you need some "Run" --> "Clean up and  Build" or even a clean 
packages re-install....

I fixed it.

I think so. I don't know what is wrong with that in the Android 8.0.0,
maybe we should disable that for now until we know what the problem,
I'm not pretty sure if it caused by Java template (maybe?), because I
don't understand Java when I tried to inspect the codes.

(edit)
Sorry... There's something wrong with my LAMW installation. 
Now, I can't compile my project after deleting my old LAMW
installation. I'll try to reinstall Lazarus.
It's maybe the culprit of why LAMW copying the wrong Java template,
even after I've installed newer LAMW. It's caused by different path of
an old and new installation.

It's says Fatal: [EFOpenError] Failed: Unable to open file
"my_old_path\android_wizard\smartdesigner\java\Controls.java"

----------------------------------------------------------------------
jmpessoa · 2019-08-24 06:06

QuoteI think there's something is wrong....

Yes!  your jPanel.java  is outdated!!!!!

This means that you have only partially updated to the "LAMW 0.8.5"
!!!

You can do a  "diff" from the "jPanel.java" on git:

I just found the LAMW.ini in the Lazarus config folder. That's why it
trying to copying my old LAMW.
I think that "flag:=false" in TLamwGlobalSettings.ReloadIni is okay to
removed, since I have multiple LAMW.

Hello, Marquez. Can you inspect on unit LamwDesigner on line 1812?

So, I have 2 forms, the first is actSplash (with name ControlSplash),
and the second is actMain (with name ControlMain).
If I modified properties in actMain, it forcing an update on
ProjectStartModule into ControlMain. So, it makes me to always modify
the LPI file.

I have an idea here. How about make actSplash is prioritized than
actMain. Like this:

Code: Pascal  [Select][+][-]window.onload = function(){var x1 =
document.getElementById("main_content_section"); if (x1) { var x =
document.getElementsByClassName("geshi");for (var i = 0; i     if
(Instance = AndroidForm)    and (AndroidForm.ActivityMode in [actMain,
actSplash])    and FProjFile.IsPartOfProject then    begin      if
AndroidForm.ActivityMode = actSplash then       
LamwSmartDesigner.UpdateProjectStartModule(AndroidForm.Name)     
else       
LamwSmartDesigner.UpdateProjectStartModule(AndroidForm.Name);    end;
       
Thank you.

Hi everyone) Android Module Wizard is a good job. Although I do not
like Pascal, it is probably a better Android app development tool than
Delphi. The most important feature is the size of the application,
with the same code it can vary 25 times. It is very important. Thank
you very much!

So. I added some functionality to the jBitmap, jCanvas, and
jDrawingView component classes. Now in order:
1. jBitmap. Added function: Code: Pascal  [Select][+][-]window.onload
= function(){var x1 = document.getElementById("main_content_section");
if (x1) { var x = document.getElementsByClassName("geshi");for (var i
= 0; i LoadFromBuffer (buffer: pointer; size: integer);2. jCanvas and
jDrawingView. Added overloaded functions: Code: Pascal
 [Select][+][-]window.onload = function(){var x1 =
document.getElementById("main_content_section"); if (x1) { var x =
document.getElementsByClassName("geshi");for (var i = 0; i procedure
DrawBitmap(bitMap: jObject; srcLeft, srcTop, srcRight, srcBottom,
dstLeft, dstTop, dstRight, dstBottom: Integer);procedure
DrawFrame(bitMap: jObject; srcX, srcY, srcW, srcH, X, Y, W, H:
Integer; rotateDegree: Single=0); procedure DrawFrame(bitMap: jObject;
X, Y, Index, Size: Integer; scaleFactor: Single=1; rotateDegree:
Single=0);
I attach the modified files, as well as a new demo using them. In
addition, two utilities are included:
1. bin2pas - a packer of binary files in * .pas
2. JC Sign - a program for convenient viewing of signatures of *
.class java files.

Have fun

1. Added a new type in the AndroidWidget unit:
Code: Pascal  [Select][+][-]window.onload = function(){var x1 =
document.getElementById("main_content_section"); if (x1) { var x =
document.getElementsByClassName("geshi");for (var i = 0; i type// ... 
PColor = ^TColor;  TColor = -$7FFFFFFF-1..$7FFFFFFF;
2. I modified and fixed some functions in the jDrawingView component.
So:
New overloaded and some function: jDrawingView.pas
Code: Pascal  [Select][+][-]window.onload = function(){var x1 =
document.getElementById("main_content_section"); if (x1) { var x =
document.getElementsByClassName("geshi");for (var i = 0; i

DrawRoundRect(float _left, float _top, float _right, float _bottom,
float _rx, float _ry) {        mCanvas.drawRoundRect(_left, _top,
_right, _bottom, _rx, _ry, mDrawPaint);}There was a problem while
displaying Cyrillic in DrawText functions. The program failed with an
error. Please modify functions ..DrawText Code: Pascal

So this could be happening all over LAMW?

----------------------------------------------------------------------
kordal · 2019-10-04 21:33

In theory. It is necessary to check while I noticed an error only in
the jDrawingView module in DrawText functions. It is likely that all
those modules that use the same approach for text output will fail.
Just in case, version FPC 3.2.0, Lazarus 2.0.2, Aarch64 chipset,
jdk1.8.0_221, SDK 29, APK Builder - Ant. All tests were conducted on a
real Android devices.

upd. Code: Pascal  [Select][+][-]window.onload = function(){var x1 =
document.getElementById("main_content_section"); if (x1) { var x =
document.getElementsByClassName("geshi");for (var i = 0; i jParams [0]
.l: = env ^ .NewStringUTF (env, PChar (_text)); After several
rebuilding of the project and LAMW, it worked. Need more tests. The
problem arose precisely with the Cyrillic text.

1. I converted the drawing functions to the Float version, because
everywhere they use Float coordinates instead of Integer. Therefore,
it will be more correct.

I updated jDrawingView and added methods for working with shaders:
BitmapShader, LinearGradient, RadialGradient, SweepGradient. I'll post
the source code a bit later.

upd. Redid everything and put it out in a separate component
JPaintShader that works with JCanvas, JDrawingView

Example:

Hi all, its posible to convert or get the real file path from a
content uri like content://... to /strorage/sdcard...

----------------------------------------------------------------------
kordal · 2019-11-08 00:44

@Segator, hi) Maybe ? Code: Pascal  [Select][+][-]window.onload =
function(){var x1 = document.getElementById("main_content_section");
if (x1) { var x = document.getElementsByClassName("geshi");for (var i
= 0; i Self.GetInternalAppStoragePath(): String // get application
pathSelf.GetEnvironmentDirectoryPath(dirDCIM): String // ex. get DCIM
directory, return: /storage/emulated/0/DCIM(* TEnvDirectory =
(dirDownloads,                    dirDCIM,                   
dirMusic,                    dirPictures,                   
dirNotifications,                    dirMovies,                   
dirPodcasts,                    dirRingtones,                   
dirSdCard,  // <------------------------------- sdcard               
   dirInternalAppStorage,                    dirDatabase,            
      dirSharedPrefs,                    dirCache); *) 
@jmpessoa, I finally finished working on a new component -
JPaintShader, which works in tandem with JCanvas or JDrawingView. As
promised, here are the sources and some new demos. I hope I haven’t
forgotten anything

@kordal, hi thats is good for fixed path but i am talking about
convert a content uri from a intent activity like when you open an
imagen file with your app the system send a uri string like
content://media/external/images/media/112 but this content have a real
file path like /storage/sdcard/Pictures/imagen.jpg so i want to
convert it content uri to the real path

Hi jmpessoa! After updating LAMW, a bug got out of the repository. In
previous versions of this was not observed. I venture to suggest that
the name of the original file is taken from the component class name,
which is written in Pascal, and not just copied from LAMW. What for?
Java source file names are case sensitive.

----------------------------------------------------------------------
jmpessoa · 2019-11-21 06:39

QuoteI venture to suggest that the name of the original file is taken
from the component class name, which is written in Pascal,....

Terrible! I have no idea where this can happen ...

----------------------------------------------------------------------
jmpessoa · 2019-11-21 22:44

Fixed  ["a short term solution"]

("smartdesigner.pas"   line 1606....)

add suppport to 'J' [upcase] in componet  class name...as in
"JPaintShader"

----------------------------------------------------------------------
kordal · 2019-11-22 01:37

Thanks for the help. We will find out where this mysterious mistake
came from.

----------------------------------------------------------------------
kordal · 2019-11-22 06:27

Your method did not work. I found a more elegant solution that does
not limit the case of writing components. Original JAVA files remain
with their names and are not renamed based on the component name.

So, the problem was this:
SmartDesigner.pas
Code: Pascal  [Select][+][-]window.onload = function(){var x1 =
document.getElementById("main_content_section"); if (x1) { var x =
document.getElementsByClassName("geshi");for (var i = 0; i // ... line
1863if FileExists(LamwGlobalSettings.PathToJavaTemplates + jclassname
+ '.java') then   begin   
 list.LoadFromFile(LamwGlobalSettings.PathToJavaTemplates + jclassname
+ '.java');     list.Strings[0]:= 'package ' + FPackageName + ';';   
 list.SaveToFile(FPathToJavaSource + jclassname + '.java'); // In my
case jclassname = JPaintShader, the original jPaintShader.java file.
Crash!                                                               
                         // Since FileExists is not case sensitive,
the code worked.// ... 
What i suggest:
Code: Pascal  [Select][+][-]window.onload = function(){var x1 =
document.getElementById("main_content_section"); if (x1) { var x =
document.getElementsByClassName("geshi");for (var i = 0; i // returns
the original file name from the JAVA template directory// ex: JClasSs
= class(JControl) -> jClass.javafunction
TLamwSmartDesigner.IsCorrectFileName(const Path, FileName: String):
String;var  SR: TSearchRec;  begin  Result := FileName;  if
FindFirst(Path + FileName, faAnyFile, SR) = 0 then    Result :=
SR.Name;  FindClose(SR);end;        // ...if
FileExists(LamwGlobalSettings.PathToJavaTemplates + jclassname +
'.java') then   begin   
 list.LoadFromFile(LamwGlobalSettings.PathToJavaTemplates + jclassname
+ '.java');     list.Strings[0]:= 'package ' + FPackageName + ';';   
 list.SaveToFile(FPathToJavaSource +
IsCorrectFileName(LamwGlobalSettings.PathToJavaTemplates, jclassname +
'.java'));     // classes can now be written case-insensitively :) //
... 
The classes can now be written case-insensitively, file names are
taken from the JAVA template directory. On Linux, this should also
work because TSearchRec is cross-platform, but I have not tested it.

----------------------------------------------------------------------
jmpessoa · 2019-11-22 06:32

Ok, kordal!

I will try your solution!

Thank you!

    Commited!!!

Can you write a guide on how to make an own component into lamw ?

I have a while on using flutter and its experience on app seem be more
native than lamw's, but making an app with lamw still be easier, hope
we can have more components for use  (May i will contribute for some
examples of IoT/Arduino/ARM/AVR  )

CreateClick right mouse button
Note: When you write bridge functions in Pascal, pay attention to the
names of functions in Java code and how they are called in JNI. A
prerequisite is the presence of signatures for functions that change
depending on the input / output parameters (arguments).

Example (the example is not complete):
jMyComponent.java
Code: Java  [Select][+][-]window.onload = function(){var x1 =
document.getElementById("main_content_section"); if (x1) { var x =
document.getElementsByClassName("geshi");for (var i = 0; i // package
org.lamw...; // changes automatically  //// skip two lines import
android.os.Bundle;// other imports// see
https://developer.android.com/reference public class jMyComponent {  
// Java-Pascal Interface    private long     pascalObj   = 0;    //
Pascal Object    private Controls controls    = null; // Java/Pascal
[events] Interface ...    private Context  context     = null;      //
constructor   public jMyComponent(Controls _Ctrls, long _Self /*,
other parameters*/ ) {                context   = _Ctrls.activity;   
           controls  = _Ctrls;                pascalObj = _Self;     
            }   // destructor  public void jFree() {     // free local
objects...  }     public int Sum(int a, int b) {     return a + b; 
} } 
MyComponent.pas
Code: Pascal  [Select][+][-]window.onload = function(){var x1 =
document.getElementById("main_content_section"); if (x1) { var x =
document.getElementsByClassName("geshi");for (var i = 0; i   //
...type    jMyComponent = class(...)    // initialization code    //
...    function Sum(a, b: Integer): Integer;   end;   function
jMyComponent.Sum(a, b: Integer): Integer;  begin    if FInitialized
then      Result := jMyComponent_Sum(FjEnv, FjObject, a, b);  end;  
// JNI implementation  function jMyComponent_Sum(env: PJNIEnv;
_jmycomponent: JObject; _a, _b: Integer): Integer;  var    jParams:
array[0..1] of JValue;    jMethod: JMethodID = nil;    jCls   : JClass
= nil;         begin    jParams[0].i := _a;    jParams[1].i := _b;   
jCls := env^.GetObjectClass(env, _jmycomponent);    jMethod :=
env^.GetMethodID(env, jCls, 'Sum', '(II)I'); // function name 'Sum',
signature (I - integer, I - integer) result Integer      Result :=
env^.CallIntMethodA(env, _jmycomponent, jMethod, @jParams);     //

And_jni.pas & other components    env^.DeleteLocalRef(env, jCls);    
                               end;   // signatures(*      Z -
Boolean  B - Byte  I - Integer  F - Float (Single)  V - Void (no
result)   L - java Object  [ - array, ex [I - integer array, [F -
float array, etc. *) 
To view signatures of compiled java files, you can use, for example,
JCSign tool.

   Author: Jose Marques Pessoa

      https://github.com/jmpessoa/lazandroidmodulewizard

:: How to Create JNI Bridge Component code::
 
1. LAMW Component Model: 

   ::  jControl: No GUI Control     

       hint: you can use composition or inheritance model here....

   ::  jVisualControl: GUI Control

       warning:  you MUST use inheritance model here.....

2. Creating a new component:
    
   2.1. Right click Java tab:

   2.1. Insert a new [wrapper] java class  jControl/jVisualControl
from template;

        hint1. Alternatively, you can paste you java code [template
compatible] from clipboard!

        hint2. Alternatively, you can import a "JAR" file and selec a
class [at the moment, only for no visual  control]!

        hint3: You can also use the demo AppTryCode3 to produce a
complete [wrapper]  java class !

       hint4. you do not need to build the "perfect" component now
.... later you can add more methods, events and properties! [sections
3 e 4 bellow]

        warning/important: All "imports" from "Controls.java"
template  and new "imports" from you java class code
                   will  be researched to try write the correct JNI
methods signatures.....

                     
   2.2. Rename [and extends] the new class [and constructor], write
some custom field, methods, etc...
        [for "JAR" imported class this task is automated! ]
       
        guideline: please, preferentially init your news params names
with "_", ex: int _flag, String _hello ...
        
        hint1: Only public methods will be translated to pascal
[bridge] code.
        hint2:  use the  mask  /*.*/   to make a public method
invisible for the parse [ex.  /*.*/public myfunctio() {....} ] 

   2.3. Select all  the new java class code and right click it [java
tab] .
     
       hint1:  if have only one java class code you do not need select
it! just right click it!
       hint2. save your java class source code in LAMW folder
"......\android_wizard\smartdesigner\java" :

        warning:  the  LAMW java to pascal convert dont support
complex/generic types like  "java.util.Map<,>" ,  "java.util.Set<>"
etc..
       So, we need re-write  the method signature [by hand] for
primitives data/array type....

      But simple java Object param [or return]  is ok   [including
array!!!]!
    
      public void SetImage(Bitmap _image) {     //<<----  OK!
             this.setImage(_image);
      }

     public Bitmap GetImage(Bitmap _image) {     //<<---- OK!
             return this.getImage();
      }

       warning/important: All "imports" from "Controls.java" template 
and new "imports" from you java class code
                   will  be researched to try write the correct JNI
methods signatures.....
     
   2.4. Popup Menu: Select "Write [Draft] Pascal
jControl/jVisualControl Interface".

   2.5. Right click Pascal Tab  and select "Register Component..."
from  Popup Menu;

          warning: Mac users: please, you must copy the console app
"lazres" [lazarus/tools] to the folder

   2.11. Wait .... Lazarus re-building ...

   2.12. The new component  is on "Android Bridges Extra" [or
other...] palette!.
  
   3. Added more methods to your component  

   3.1.  write new method to  your ".java" code
           ex.
                 public void SetFoo(int _foo) {
                       mFoo = _foo;
                 }

   3.1.  In java tab write a draft java class code to wrapper the
[new] methods;

           class jMyComponent {

                 public void SetFoo(int _foo) {
                       mFoo = _foo;
                 }
                  public int GetFoo() {
                        return mFoo;
                  }
          }                
          
    3.2   Right click the Java tab and select "Write [draft]
complementary Pascal Interface"

    3.4   Copy the the pascal interface code to your component unit!!!
       
    4. Added "native" [events] methods to your component

    4.1.  write the native method "call" to to  your ".java" code   
[study some LAMW code as example!]

               ex1:   [from jSpinner.java]

               
controls.pOnSpinnerItemSelected(pascalObj,position,caption); 
 //return void

              ex2:   [fiction...]
                int  i =
controls.pOnSpinnerItemSelected(pascalObj,position,caption); 
 //return int             

              ex3:   [fiction...]
                int[] v;
                 v =
controls.pOnSpinnerItemSelected(pascalObj,position,caption); 
 //return int[]     
                 for (int i = 0; i < v.length; i++) {
                     //Log.i("v["+i+"]", ""+v);     //do some use...
                 }         
               
              ex4:   [fiction...]
                String[] s;
                 s =
controls.pOnSpinnerItemSelected(pascalObj,position,caption); 
 //return String[]               
                for (int i = 0; i < s.length; i++) {
                     //Log.i("s["+i+"]", ""+s);     //do some use...
                 }         

    4.2.  write the native method signature to your [component]
".native" file    [study some LAMW code as example!]
           ex1.    [from jSpinner.native]      
              public native void pOnSpinnerItemSelected(long pasobj,
int position, String caption);

           ex2.    [fiction...]      
              public native int pOnSpinnerItemSelected(long pasobj,
int position, String caption);

           ex3.    [fiction...]      
              public native int[] pOnSpinnerItemSelected(long pasobj,
int position, String caption);

           ex4.    [fiction...]      
              public native String[] pOnSpinnerItemSelected(long
pasobj, int position, String caption);

    4.3.  In java tab write a draft java class code to wrapper the the
native [one line!] method;
        
           class jMyComponent {

                public native void pOnMyComponentItemSelected(long
pasobj, int position, String caption); //MyComponent

          }                

         NOTE: the  "//MyComponent" signs the part of the method name
that will be overshadowed in the nomination of the property.
                            ex.  FOnItemSelected   [ not
FOnMyComponentItemSelected  ]  

    4.4   Right click the Java tab and select "Write [draft]
complementary Native Method Pascal Interface"

    4.5   Copy the the pascal interface code [generated] to your
component unit [mycomponent.pas] and to
"Laz_And_Controls_Events.pas"!!!

    Congratulations!!!

Hi @jmpessoa, @TR3E 
1. There is an error in the Code: Pascal  [Select][+][-]window.onload
= function(){var x1 = document.getElementById("main_content_section");
if (x1) { var x = document.getElementsByClassName("geshi");for (var i
= 0; i function GetTimeInMilliseconds: Longint function, it returns a
negative value! The fact is that the Integer type does not have enough
bit depth for the correct operation of the time counter.

The problem arises is data types on the Pascal side.
GetTimeInMilliseconds is of type Longint = Integer = jInt = Int
(java), and should be Int64 = jLong = Long (java). As a result, the
function calls another jni_func_out_j, where there is also a problem
with data types.

So, we have at least several problematic calling functions
Code: Pascal  [Select][+][-]window.onload = function(){var x1 =
document.getElementById("main_content_section"); if (x1) { var x =
document.getElementsByClassName("geshi");for (var i = 0; i function
jni_func_out_j: Longint; // change Longint to Int64function
jni_func_j_out_t(..: Longint) ...; // change Longint to Int64 , where
the types Longint and Int64 are mixed up.

2. I`am updated the jDrawingView component. The OnClick and
OnDoubleClick events have been added.
So, the first modification:
Controls.java, added to line 165, 166
Code: Java  [Select][+][-]window.onload = function(){var x1 =
document.getElementById("main_content_section"); if (x1) { var x =
document.getElementsByClassName("geshi");for (var i = 0; i class Const
{  public static final int TouchDown            =  0;  public static
final int TouchMove            =  1;  public static final int TouchUp
            =  2;  public static final int Click                =  3;
// new  public static final int DoubleClick          =  4;  // new 
public static final int Click_Default        =  0;} AndroidWidget.pas,
added to line 71, 72 and two new functions
Code: Pascal  [Select][+][-]window.onload = function(){var x1 =
document.getElementById("main_content_section"); if (x1) { var x =
document.getElementsByClassName("geshi");for (var i = 0; i // Event id
for Pascal & Java  cTouchDown            = 0;  cTouchMove            =
1;  cTouchUp              = 2;  cClick                = 3; 
cDoubleClick          = 4; // ...  procedure jni_proc_s(env: PJNIEnv;
_jobject: JObject; javaFuncion : string; _short: smallint);  procedure
jni_proc_ss(env: PJNIEnv; _jobject: JObject; javaFuncion : string;
_short1, _short2: smallint);  // ...implementation// ...  procedure
jni_proc_s(env: PJNIEnv; _jobject: JObject; javaFuncion : string;
_short: smallint);  var    jParams: array[0..0] of jValue;    jMethod:
jMethodID = nil;    jCls   : jClass = nil;  begin    jParams[0].s:=
_short;     jCls := env^.GetObjectClass(env, _jobject);    jMethod :=
env^.GetMethodID(env, jCls, PChar(javaFuncion), '(S)V');   
env^.CallVoidMethodA(env, _jobject, jMethod, @jParams);   
env^.DeleteLocalRef(env, jCls);  end;   procedure jni_proc_ss(env:
PJNIEnv; _jobject: JObject; javaFuncion : string; _short1, _short2:
smallint);  var    jParams: array[0..1] of jValue;    jMethod:
jMethodID = nil;    jCls   : jClass = nil;  begin    jParams[0].s:=
_short1;    jParams[1].s:= _short2;     jCls :=
env^.GetObjectClass(env, _jobject);    jMethod :=
env^.GetMethodID(env, jCls, PChar(javaFuncion), '(SS)V');   
env^.CallVoidMethodA(env, _jobject, jMethod, @jParams);   
env^.DeleteLocalRef(env, jCls);  end;   
The following modification affected JDrawingView.java and
DrawingView.pas, modified files in the attached.

----------------------------------------------------------------------
ADiV · 2020-01-24 08:29

Updated "jDrawingView" [thanks to Kordal]

Fixed "GetTimeInMilliseconds" long to int64 and the corresponding
"jni_func".

I have changed the variables that were in capital letters, since in
programming the constants are understood as capital, when it will not
be so.

And I have changed the FTimeClick and FTimeDoubleClick variables from
short to int.

Already uploaded to LAMW as "Pull request", it is necessary that
jmpessoa accept it.

----------------------------------------------------------------------
kordal · 2020-01-24 12:26

Thank you) I forgot to add line in the Init procedure. This is
necessary to change property values ​​in component design time.

document.getElementsByClassName("geshi");for (var i = 0; i procedure
jDrawingView.Init(refApp: jApp);// ...begin  // ...  if not

How to build Android App Bundles?

i'm trying to upload my app to Play Store and got following error

This release does not comply with the 64-bit Google Play requirements

The following APK or App Bundle is available for 64-bit devices, but
only has 32-bit native code: 2.

Enter 64-bit and 32-bit native code in your application. Use the
Android App Bundle publication format to ensure directly that each
device architecture only accepts the required native code. This will
prevent the addition of the overall application size.

https://developer.android.com/guide/app-bundle?hl=en

please help...

Quote from: nullpointer on March 07, 2020, 02:58:33 pmHow to build
Android App Bundles?

Not using Android App Bundles is NOT the reason why your app is
rejected by Google Play (see below for the real reason).

Android App Bundles (AAP files) are the *recommended* format by
google, but APK files are accepted.

Android App Bundles's (AAB) advantage over APK is this: when people
will download your app from google's play store, if you uploaded your
app in AAB format, the user will only receive one version of the
library, the one they need: downloading to a 64-bit phone will get
only the 64 bit library, and downloading to a 32-bit device will get
only the 32-bit files. If instead you uploaded your app as APK, all
the users will receive all the files, 32 and 64  bit. I think they
call that a "fat" bundle.

So AAP files are better for your users (no space wasted on their
memory and in downloaded bandwidth). But APK are still accepted.

In order to create AAB bundles, I believe you need to use Android
Studio to build the app, although I hope that at some point the
Lazarus package will become able to do that as well.

But my suggestion is to stick with APK for the time being. You already
have enough complicated things to work out, and you don't need one
more...

And now the important thing:

Quote from: nullpointer on March 07, 2020, 02:58:33 pmThis release
does not comply with the 64-bit Google Play requirements

The reason why you app was not accepted is that it didn't contain a
64-bit version of the library.

By default, LAMW/Lazarus generates 32-bit version of the library
(libcontrols.so is the default name) which contains the Pascal code
you write with LAMW.

Since August 2019, google requires a 64 bit version of any native
libraries (so files) and refuses to accept APK (or AAB) files that
only contain 32-bit versions of embedded libraries.

32-bit libraries are stored in the folder "libs\armeabi-v7a" in your
app's main folder.

(you will probably see the file libcontrols.so in that folder)

64-bit libraries are stored in the folder "libs\arm64-v8a" in your
app's main folder.

(you will probably find this folder empty)

What you need to do to get your app accepted by google is to set up a
separate 64-bit FPC compiler, which targets arm64 CPUs, and compile
your project a second time with it, so that the 64-bit file will be
created and added to the libs\arm64-v8a folder.

I had to struggle a lot to figure this out. More recently, fpdeluxe
and other projects are making the task of building both 32 and 64 bit
versions easier.

In my case, Lazarus IDE now produces a 32 bit library, and then I
separately call a script that compiles the project again, with the 64
bit compiler this time.

At that point, both of the above folders will have the libcontrols.so
file in them. If you then build the APK, both versions (32 bit and 64
bit) will be included in the APK. And when you will submit it to
google, it will be accepted.

Hi,

A week ago, I have added a Gradle option into build.gradle:

Quote    splits {
        abi {
            enable true
            reset()
            include 'arm64-v8a'
            universalApk false
        }
    }

To make a combined apk, build with Gradle and use this:

Quote    splits {
        abi {
            enable true
            reset()
            include 'armeabi-v7a','arm64-v8a'
            universalApk true
        }
    }

If needed, I can put this (mutli-arch apk) into LAMW as a new feature.

You can use Build Modes so that you can perform both compilations from
the GUI consecutively, if you'd like.

Okay, I think I know the reason why I am getting these java class not
found errors.

It is my lack of knowledge as how the java class repository is built
up for the application.
I think it looks in all files that are in the".lpr" file or it could
be as you add objects to form in the application.
Not sure.

But somehow the object was not in the java libraries for the
application.

Good question. Sometimes I get lost at some point in a project because
failures occur during execution on the device. I only started with
LAMW a few days ago. I'm exploring Android Studio and LAMW. It is a
fantastic work done by the authors of LAWM. I believe that with some
effort I can do what I need.

----------------------------------------------------------------------
HotShoe · 2020-07-20 20:25

I have run into an oddity while using LAMW. I created a new LAMW GUI
project and used a Jpanel and several jbitbuttons to re-create a
dialer app that I wrote years ago. This is just to compare the 2 and
see if there are any surprises.

Anyway. I saved my main unit as Main.pas as I always do, and I renamed
the form to Mainfrm as I always do. Everything seemed fine until I had
to shut everything down for a meeting. I saved everything and closed
Lazarus.

When I came back, I could not load the project again. I get a Property
"Caption" not found. I can still load the demo projects without a
problem, so I created a new project again and placed the same
components on the Jform again. This time I did not rename the main
form, I lseft it a AndroidModule1, and I can close the ide , re-open
it and it loads the project just fine.

I can't find any differences between the 2 projects that I created
except the name of the main form, so I suspect this is not supported,
or the renaming makes the project look like it is a standard Tform
again? Jforms do not have a caption property, but do have a Text
property. It's just a guess but something that will force me to change
my normal naming practices.

I should add that I am using Lazarus 2.0.10 and FPC 3.2.0, the latest
LAMW and the Arm and Aarch64 cross compilers.

Thanks,
--- Jem

Hi guys,

for the past two weeks, i have been trying to implement admob Rewarded
Ads starting with the good admob demo in LAMW.

Google documentation can be found here:
https://developers.google.com/admob/android/rewarded-ads

I'm not a Java expert and modifying LAMW is an hard work. I've tried a
lot of things but don't really know how to do this.

Please could you implement this for LAMW, that would be great.

Thanks.

an observation ... jcustomcamera has memory leak and Inevitable crash
after certain time saving photos ... As I have to activate jcustomcam
many times in my app, so I had to investigate. I don't know Java, but
researching it, I discovered that it was a memory leak. After testing,
I solved the problem with a line of code in jcustomcamera.java .......
bitmap.recycle (); added in private void saveBitmapToJpg (Bitmap
bitmap, String bmpPath) ....exactly after outStream.close () ;. My app
had no more problems. I hope I helped this fantastic work.

Hello All!

LAMW Ide-Tools:  NEW!  "Export LAMW Project as Template/Theme..."

Now you can use an entire project as a starting point for your nice
new app....

Warning: Make sure that the project you want to use as template works
perfectly.
Warning: Project Options/SearchPaths  -Fu  will not be exported!
Warning: secondary gApp.CreateForm in  ".lpr"  will not be exported**

Hi, All!

Now LAMW can handle "Firebase Cloud Messaging"  push notification!

NEW! "jsFirebasePushNotificationListener"  component

NEW!  demo:
AppCompatFirebasePushNotificationListenerDemo1

NEW! doc!
"how_to_handling_firebase_push_notification.txt"

QuoteHow to: Handling Firebase Push Notification in LAMW  [warning:
"beta" version ::  23-July-2021]
   (by jmpessoa)


0) Create your "AppCompat" [[theme]] project
   0.1)Put a "jsFirebasePushNotificationListener" component on form
        0.2)Go to lazarus menu and simply  "Run" --> "Build"

1) Login in your google acount [email or any....]

2) Go to "https://console.firebase.google.com/"

3) Create/Add a new Project   [ex: "MyOrg"]

4) Go to your "MyOrg" project and click "+Add app"

5) Click on Android Icon

6) In (page) "Add Firebase to your Android app":
   6.1) "Register App"
      6.1.1 ""Android package name"
         ex: org.lamw.appcompatfirebasepushnotificationlistenerdemo1

      6.1.2 CLICK the button "Register app"

   6.2) "Download config file"
                 get the "google-services.json" and put it in your
LAMW project folder

        Done!

   (don't do anything more, LAMW takes care of it all for you!)

7) Active your Internet phone/device connection

 Go to Lazarus menu "Run" --> "[LAMW] Build Android Apk and Run"

9) Go to "https://console.firebase.google.com/"

   9.1 Click the "MyOrg" project

Messaging"
   9.3 Click "New notification" Button
   9.4 Fill the form and click "Next"
   9.5 In the "Target" --> "selectan app"   [select your app
package...] and "Next"
        9.6 In the "Scheduling" --> "Now"  and "Next"
        9.7 In the bottom page click the button "Review"
   9.8 "Publish"  !!!!


Congratulations!!!


10) Notes about your/custom Payload expected by LAMW component:
   [https://firebase.google.com/docs/cloud-messaging/concept-
options?hl=en]

10.1 Notification Payload


{
"message":{
-    ...
     ...
    "notification":{
      "title" : "my message title",     // ---> "title" expected by
LAMW
      "body" : "my message body"        // ---> "body"  expected by
LAMW
    }
    ...
    ...
  }
}

Note: Notification messages are delivered to the notification tray
when the app is in the background.
For apps in the foreground, messages are handled/delivery by a LAMW
callback function for you !!!


10.2 Data Payload

{
  "message":{
    ...
    ...
    "data":{
      "title":"my message title",// ---> "title" expected by LAMW
      "body":"my message body",  // ---> "body" expected by LAMW
      "myKey1":"myValue1"        //free/custom
      "myKey2":"myValue2"        //free/custom
       ......                    //free/custom
    }
    ...
    ...
  }
}

Where myKey1, myKey2, .... are your free/custom key=value pairs ....

warning: from "data" messages only "title" and "body" are
handled/delivery by the LAMW callback function for you
         but you can read all "data" when App is "waking up" by
clicking in notification....

//by code:
Code: Pascal  [Select][+][-]window.onload = function(){var x1 =
document.getElementById("main_content_section"); if (x1) { var x =
document.getElementsByClassName("geshi");for (var i = 0; i procedure
TAndroidModule1.AndroidModule1ActivityCreate(Sender: TObject;
intentData: jObject);var  data: TDynArrayOfString;  i, count:
integer;begin  data:= jIntentManager1.GetBundleContent(intentData,
'=');  //key=value  count:= Length(data);  for i:= 0 to count-1 do 
begin     ShowMessage(data[i]);  //key=value  end;end; 
//and/or maybe:
Code: Pascal  [Select][+][-]window.onload = function(){var x1 =
document.getElementById("main_content_section"); if (x1) { var x =
document.getElementsByClassName("geshi");for (var i = 0; i procedure
TAndroidModule1.AndroidModule1NewIntent(Sender: TObject; intentData:
jObject);var  data: TDynArrayOfString;  i, count: integer;begin 
data:= jIntentManager1.GetBundleContent(intentData, '=');
 //key=value  count:= Length(data);  for i:= 0 to count-1 do  begin  
 ShowMessage(data[i]);  //key=value  end;end; 
10.3 Mixing Notification and Data Payload

{
  "message":{
    ...
    "notification":{
      "title" : "my message title",     // ---> "title" expected by
LAMW
      "body" : "my message body"        // ---> "body"  expected by
LAMW
    }
    "data":{
      "myKey1":"myValue1"        //free/custom
      "myKey2":"myValue2"        //free/custom

Is it posibble in near future LAMW modify firebase db? Just like FB4D 
Or just simply modifying by using javascript inside webview?

Thank you

----------------------------------------------------------------------
jmpessoa · 2021-08-08 22:26

QuoteIs it posibble in near future LAMW modify firebase db

Yes, we can try implement firebase "db" ...

But let's clarify:
jsFirebasePushNotificationListener component is about  "Firebase Cloud
Messaging"  push notification!

Hi, All!

Android 11 - Api 30  has restricted developers to access devices
"publics" folders (ex: "Download, Documents, ..., etc")

Developers no longer have access to a file via its path. Instead, you
need to use via “Uri“.

New!   jForm methods:

 //get user permission... and an uri
RequestCreateFile
RequestOpenFile
RequestOpenDirectory
procedure TakePersistableUriPermission

 //handling file by uri....
 function GetFileList                [edited...]
 function GetBitmapFromUri
 function GetTextFromUri
 procedure SaveImageToUri
 procedure SaveTextToUri

New demo:
"AppPublicFoldersAccessDemo1"

 function GetBitmapFromUri
 function GetTextFromUri
 procedure SaveImageToUri
 procedure SaveTextToUri

New demo:
"AppPublicFoldersAccessDemo1"

I have added function SaveBytesToUri.

The updated code is in attachment, in two files:
1) jForm.java, located at
C:\fpcupdeluxe\ccr\lamw\android_wizard\smartdesigner\java

2) androidwidget.pas, located at
C:\fpcupdeluxe\ccr\lamw\android_bridges


jmpessoa, please search the attached files for phrase “by neuro” and
copy/paste new code into LAMW distribution files.

The new code in “androidwidget.pas”:
Code: Pascal  [Select][+][-]window.onload = function(){var x1 =
document.getElementById("main_content_section"); if (x1) { var x =
document.getElementsByClassName("geshi");for (var i = 0; i procedure
SaveBytesToUri(_bytes: TDynArrayOfJByte; _toTreeUri: jObject); // by
neuroprocedure jForm_SaveBytesToUri(env: PJNIEnv; _jform: JObject;
_bytes: TDynArrayOfJByte; _toUri: jObject); // by neuro //by
neuroprocedure jForm.SaveBytesToUri(_bytes: TDynArrayOfJByte;
_toTreeUri: jObject);begin  //in designing component state: set value
here...  if FInitialized then     jForm_SaveBytesToUri(FjEnv,
FjObject, _bytes ,_toTreeUri);end; //by neuroprocedure
jForm_SaveBytesToUri(env: PJNIEnv; _jform: JObject; _bytes:
TDynArrayOfJByte; _toUri: jObject);var  jParams: array[0..1] of
jValue;  jMethod: jMethodID=nil;  jCls: jClass=nil;   byteArray:
jByteArray;  len: SizeInt; label  _exceptionOcurred;begin   jCls:=
env^.GetObjectClass(env, _jform);  if jCls = nil then goto
_exceptionOcurred;  jMethod:= env^.GetMethodID(env, jCls,
'SaveBytesToUri', '([BLandroid/net/Uri;)V');  if jMethod = nil then
goto _exceptionOcurred;   len := Length(_bytes);  byteArray:=
env^.NewByteArray(env, len);  env^.SetByteArrayRegion(env, byteArray,
0 , len, @_bytes[0]);   jParams[0].l:= byteArray;  jParams[1].l:=
_toUri;   env^.CallVoidMethodA(env, _jform, jMethod, @jParams); 
env^.DeleteLocalRef(env,jParams[0].l);   env^.DeleteLocalRef(env,
jCls);   _exceptionOcurred: jni_ExceptionOccurred(env);end;
The new code in “jForm.java”:
Code: Java  [Select][+][-]window.onload = function(){var x1 =
document.getElementById("main_content_section"); if (x1) { var x =
document.getElementsByClassName("geshi");for (var i = 0; i    
//Android 11: //by neuro    public void SaveBytesToUri(byte[] _bytes,
Uri _toTreeUri) {        OutputStream out=null;        try {         
 out =
controls.activity.getContentResolver().openOutputStream(_toTreeUri,
"w");             out.write(_bytes);            out.flush();        }
catch (FileNotFoundException e) {            e.printStackTrace();    
  } catch (IOException e) {            e.printStackTrace();        } 
 }   


Usage example:
Code: Pascal  [Select][+][-]window.onload = function(){var x1 =
document.getElementById("main_content_section"); if (x1) { var x =
document.getElementsByClassName("geshi");for (var i = 0; i var 
array_of_bytes: array of byte;  array_of_jbytes: TDynArrayOfJByte;  n,
size_of_array: Integer; begin   size_of_array :=
256;setLength(array_of_bytes, size_of_array);
 setLength(array_of_jbytes, size_of_array); for n := 0 to
size_of_array-1 dobeginarray_of_bytes[n] := Byte(128); // here set the
values of byte arrayarray_of_jbytes[n] :=
JByte(array_of_bytes[n]);end; Self.SaveBytesToUri(array_of_jbytes,
treeUri);   end;

We also need function
GetBytesFromUri
which is not yet available.

In sample project AppPublicFoldersAccessDemo1
two buttons work (“Request Create File” and “Request Open Directory”),
however third button “Request Open File” does not work – nothing
happens when this button is pressed.
I guess this button should invoke system file picker (equivalent of
open file dialog), however it does not work.
I am running AppPublicFoldersAccessDemo1 on Android 8.1 (device:
Samsung Galaxy Tab A 10.1).
I have fixed this bug in the post below.

----------------------------------------------------------------------

I have fixed the bug in sample project AppPublicFoldersAccessDemo1.
The problem was that button “Request Open File” does not work.
The fixed code should be replaced in file “androidwidget.pas”, located
at
C:\fpcupdeluxe\ccr\lamw\android_bridges

Code: Pascal  [Select][+][-]window.onload = function(){var x1 =
document.getElementById("main_content_section"); if (x1) { var x =
document.getElementsByClassName("geshi");for (var i = 0; i procedure
jForm_RequestOpenFile(env: PJNIEnv; _jform: JObject; _uriAsString:
string; _fileMimeType: string; _requestCode: integer);var  jParams:
array[0..3] of jValue; // <<---- bug fixed  jMethod: jMethodID=nil; 
jCls: jClass=nil;label  _exceptionOcurred;begin   jCls:=
env^.GetObjectClass(env, _jform);  if jCls = nil then goto
_exceptionOcurred;  jMethod:= env^.GetMethodID(env, jCls,
'RequestOpenFile',
'(Ljava/lang/String;Ljava/lang/String;Ljava/lang/String;I)V'); //
<<---- bug fixed  if jMethod = nil then goto _exceptionOcurred;  
jParams[0].l:= env^.NewStringUTF(env, PChar(_uriAsString)); 
jParams[1].l:= env^.NewStringUTF(env, PChar(_fileMimeType)); 
jParams[2].l:= env^.NewStringUTF(env, PChar(nil)); // <<---- bug
fixed  jParams[3].i:= _requestCode;  // <<---- bug fixed  
env^.CallVoidMethodA(env, _jform, jMethod, @jParams); 
env^.DeleteLocalRef(env,jParams[0].l); 
env^.DeleteLocalRef(env,jParams[1].l); 
env^.DeleteLocalRef(env,jParams[2].l); // <<---- bug fixed  
env^.DeleteLocalRef(env, jCls);   _exceptionOcurred:
jni_ExceptionOccurred(env);end;
jmpessoa, please update function “jForm_RequestOpenFile” in file
“androidwidget.pas” with the fixed code above.


Another problem – in file:
C:\fpcupdeluxe\ccr\lamw\demos\GUI\AppPublicFoldersAccessDemo1\jni\unit
1.pas
the code does not work:
Code: Pascal  [Select][+][-]window.onload = function(){var x1 =
document.getElementById("main_content_section"); if (x1) { var x =
document.getElementsByClassName("geshi");for (var i = 0; i //or if
mimetype is
"image/*"ImageView.SetImage(Self.GetBitmapFromUri(treeUri));
I suspect that the problem is inside file
C:\fpcupdeluxe\ccr\lamw\android_wizard\smartdesigner\java\jForm.java
in program code of function:
Code: Java  [Select][+][-]window.onload = function(){var x1 =
document.getElementById("main_content_section"); if (x1) { var x =
document.getElementsByClassName("geshi");for (var i = 0; i //Android
11:public Bitmap GetBitmapFromUri(Uri _treeUri)
However I still do not know how to fix it.

First: thank you!

But, if possible, can you submit a "pull request" for changes in
github?

For a fresh install of Lazarus/FPC/LAMW (using FPCUPdeluxe) on Linux
and Windows, I am getting an error when I do the following:

1) Close Lazarus and reopen it.
2) Create a new LAMW GUI project
3) Try to place controls on the form.

For example when I try to put a jButton on the form I get an error
message:  "Error moving component JButton1:JButton".  (and the jButton
never shows up on the form.)

But if I save the project and re-open it, the error message is gone
and it works as expected.  If I open a demo project, they also work
properly.

Please see attached error message.
