hi truetom, thanks very much

my friend said I also use jhttpclient in lamw
with fphttpclient i can use this code to get infomations about site's
header

Code: [Select]try

for i:=0 to http1.ResponseHeaders.Count-1 do
begin
s:=http1.ResponseHeaders.Strings[i];   

infomations about site's header can get by command ReponseHeaders ( as
above ),
but I couldn't find anything same as it in list of commands of
jhttpclient

Handoko · 2015-10-02 17:55

Thanks for the new release.

I tested this svn 49903 + LazToAPK 0.9.0.32 but unfortunately the
generated i386-android code can't run on my Asus Zenfone 2 Intel Atom
Quad Core smart phone. The generated APK file can be installed without
problem. But if I run it, this error message will show up:
"Unfortunately, Project1 has stopped."

For your information, I'm using:
- NDK 4.1.2 (API 16)
- SDK 22.0.1
- WinXP sp 3


Things changed for generate the code:
- Target CPU Family: i386
- Library Path: ..\..\downloads\android-
ndk-r10d\platforms\android-16\arch-x86\usr\lib
- Custom Options: -dANDROID -Xd

Are those settings above not correct for generate x86 code? Or is
there anything I missed? Has anybody here ever succeed to create
program for Intel-based Android?

Please help.

----------------------------------------------------------------------
DelphiFreak · 2015-10-02 18:39

Hello Handoko, I have never tried to build an i386 android app. And I
think that laz4android is for arm only. So you are experimenting alone
on this task. Let me know if you get it working.

----------------------------------------------------------------------
Handoko · 2015-10-03 08:03

I'm alone. 

Can you please help me or at least share more information where should
I put the APP_ABI := x86 parameter?

I googled the web and found that to build i386 android app, we have to
use APP_ABI := x86 parameter. Here are the sources:

https://software.intel.com/en-us/android/articles/android-ndk-for-
intel-architecture
http://stackoverflow.com/questions/10098049/android-ndk-build-
ignoring-app-abi-x86
http://www.codeproject.com/Articles/867762/Creating-an-x-and-ARM-APK-
using-the-Intel-Compil

Here I quote the information so you don't have to read the whole
articles:

QuoteIn the NDK for Intel Architecture, use "APP_ABI := x86 " command
line parameter. This generates the shared library under
$PROJECT/libs/x86/ $NDK/ndk-build "APP_ABI := x86 "
QuoteAdd target compile platform to it:
    APP_ABI := x86
QuoteUse the command below to build the application binary with Intel
compiler for x86 architecture:
$ ndk-build APP_ABI=x86 V=1 NDK_TOOLCHAIN=x86-icc
NDK_APP.local.cleaned_binaries=true
What I guess is laz4andoid actually generated the proper code for
i386, but unfortunately it didn't pass the "APP_ABI := x86" parameter
when calling NDK (or SDK), so the final code isn't generated
correctly.

Can you please let me know in which file I should add the parameter?

----------------------------------------------------------------------
chenyuchih · 2015-10-03 16:47

To Handoko,

I can successfully compile for x86-Android and my project option setup
are as follows,

Target OS:
Android

Target CPU family:
i386

Target processor:
(Default)

Library Path:
$(LazarusDir)\Android_NDK\platforms\android-9\arch-x86\usr\lib;
$(LazarusDir)\Android_NDK\toolchains\x86-
4.8\prebuilt\windows\lib\gcc\i686-linux-android\4.8

and no Custom Options.

Maybe you missed my second library path.

----------------------------------------------------------------------
Handoko · 2015-10-03 18:57

Thanks chenyuchih, but unfortunately it's no help. The result is the
same as my previous builds. The compilation and linking processes were
smooth without error. And the APK file can be installed without
problem. But if I run the app, it will say "Unfortunately, Project1
has stopped."

I have tried different compilation options and reinstalled laztoapk
several times, but still can't find the correct way to make it works
on my phone. I'm thinking it might be something wrong in my phone. But
it seems working correctly, I can use it to browse Internet and
running other apps. Or maybe because it is an Intel 64-bit so it
required different option for the compilation process.

----------------------------------------------------------------------
chenyuchih · 2015-10-04 01:47

Well, it's so bad that I helped nothing at all...

Actually, I just use Laz4Android for making shared object(*.so) files,
not the whole complete apk. My GUI still write in Java and use JNI to
call my native core functions. It works well for me under armeabi/x86
CPUs. I am not sure that why it's not okay for you because the basic
concept should be the same.

Maybe you can give the following simple checks a try:

1. Extract the apk and see if the file structure is correct. Under the
unzipped directory, there is a "lib" folder and there should be 2 sub-
folders(armeabi & x86) in "lib". Check if the files in those 2 sub
folders correspond to the CPU structure.

2. Write a simplest "Hello World" test app to see whether it works. If
it works, maybe there's something wrong in your code?

Just for your reference.

Regards,
ChenYuChih

Have you checked what `adb logcat` says? It's an essential debugging
tool for Android.

There is only 1 folder under the lib folder: armeabi. And it contain 1

Quote from: Leledumbo on October 04, 2015, 11:55:27 amHave you checked

I can't use adb logcat. Because to test my apk file I have to run it
directly on my phone. LazToApk is installed in a VirtualBox on my
Linux computer, so I can't install Intel HAXM which is required by
Android AVD to emulate Intel Atom x86. If I run the AVD to emulate
x86, an error will show up and say "Please ensure Intel HAXM is
properly installed and usable."

FYI, if I use the Laz4Android default settings to build ARM apk, the
result can be run correctly on AVD ARM. But the ARM-version apk can't
run on my phone. Below is the picture of ARM-version apk running AVD:

----------------------------------------------------------------------
Handoko · 2015-10-04 15:58

As suggested by chenyuchih, I have changed the Library Path and empty
the Custom Options. For the Library Path, I have tried both android-9
and android-16.

----------------------------------------------------------------------
Handoko · 2015-10-04 16:10

Am I allowed to attach the apk files here? So somebody may check and
test them on ARM/x86 phones. I only have one Intel-based phone.

This is certainly your problem. Your app is not built for x86 android,
only arm.

only arm.

Okay, so now we found the problem. Can you please check my steps and
see where I did it wrong?

The steps I used to produce the apk file:
1. Start VirtualBox and run the WinXP sp 3 machine
2. Empty project1 folder (remove all files created from previous
attempts)
3. Start LazToApk and click the "manual" tab
4. Click "Step 1: Select/Create Project Folder" and point it to
project1 folder
5. Set the password: 123456
6. Start Lazarus and open "project1android.lpi" in the project1 folder
7. Add "..\..\downloads\android-
ndk-r10d\platforms\android-16\arch-x86\usr\lib" to the Library Path
8. Add "..\..\downloads\android-
ndk-r10d\toolchains\x86-4.8\prebuilt\windows\lib\gcc\i686-linux-
android\4.8" to the Library Path
9. Move the ARM item to the lowest in the search path
10. Set Config and Target to Android, i386, (Default)
11. Empty the Custom Options (remove -dANDROID -Xd -CpARMV6)
12. Press the "Save All" button to update all the changes in Lazarus
13. Close Lazarus, so now back to LazToApk
14. Click "Step 2: Build Project"
15. Wait until it said "145 lines compiled, 8.0 sec. 2 warning(s)
issued. 10 hint(s) issued"
16. Click "Step 3: Create Android Key" and answer the questions
17. Click "Step 4: Create APK File"
18. The APK file is generated

Additional information you may need to know:
- Computer: Intel Core 2 Quad with Ubuntu 15.04 64-bit + MATE Desktop
1.8.2
- Phone: Asus Zenfone 2 Intel Atom Quad Core 64-bit with Android 5.0
- Oracle VirtualBox 4.3.26 with WinXP sp3 virtual machine
- LazToApk version 0.9.0.32
- Laz4Android version 1.5-49903-FPC3.1.1
- Lazarus version 1.5 SVN 49563 with FPC 3.1.1
- SDK Build-Tool version 22.0.1
- NDK-Platform version 4.1.2 (API 16)
- Java JDK version 1.8.0_51
- Project1 path: C:\laztoapk\projects\project1
- APK file and path:
C:\laztoapk\projects\project1\android\bin\project1.apk
- Items in Library Path:
C:\laztoapk\downloads\android-
ndk-r10d\platforms\android-16\arch-x86\usr\lib
C:\laztoapk\downloads\android-
ndk-r10d\toolchains\x86-4.8\prebuilt\windows\lib\gcc\i686-linux-
android\4.8
C:\laztoapk\downloads\android-ndk-r10d\platforms\android-16\arch-
arm\usr\lib

I checked the steps again and again. I can't find anything wrong. Did
I missed something?

I'm not familiar with adb, did you mean the file adb_logcat.bat that
can be found in the ...\projectpath\android? I run it, but it said
"waiting for device" and then nothing happened even I plugged usb
cable to my phone. I think it won't able to connect to my phone
because it was running in VirtualBox. Actually it works, but only if I
run in emulator mode.

Do you think I should have a real Windows environment to run LazToApk
and the AVD (not using VirtualBox)? I own a licensed Windows, but I'm
reluctant to make my computer multi-boot.

Hello Handoko!

1. There is a updated Laz4Android by TrueTom [some fixed!]

    ref. http://sourceforge.net/projects/laz4android/

Last update:2015-10-02
FPC: 3.1.1 trunk svn 31903 win32/arm-android/i386-android/jvm-android
Lazarus:1.5 trunk svn 49903
Android NDK: r10e (arm-linux-androideabi-4.9 + x86-4.9)

--->Fixed can't compiled customdrawn.lpk problem.
--->Fixed examples\androidlcl\sqlitejniandroid.pas,compiled ok.

2. Note:    -->> Android NDK: r10e (arm-linux-androideabi-4.9 +
x86-4.9)

----------------------------------------------------------------------
Handoko · 2015-10-05 18:45

Thanks jmpessoa. Actually I've already used the latest update of
Laz4Android you mentioned (Laz4Android version 1.5-49903). The thing I
didn't pay attention was the NDK version 10e (x86-4.9).

So I downloaded Android NDK r10e, unzipped it to
C:\laztoapk\downloads\android-ndk-r10e and set my Library Path to:
C:\laztoapk\downloads\android-
ndk-r10e\platforms\android-16\arch-x86\usr\lib
C:\laztoapk\downloads\android-
ndk-r10e\toolchains\x86-4.9\prebuilt\windows\lib\gcc\i686-linux-
android\4.9

Everything seemed okay so I saved the project file, rebuild the
project and create the APK again. Unfortunately the result was the
same.

Also, as chenyuchih and Leledumbo said, I should have an x86 folder
under ..\lib inside the apk file. I don't know why I only get an
armeabi folder. After some attempts, I found that if I rename the
folder before the generation of apk file I will get the file under the
folder "x86". Even now I can generate fat binaries, the code still
can't run on my phone. It can be installed, but an error message
"Unfortunately, Project1 has stopped." will show up if I run it.

Hello Handoko,

I think it's not laz4android problems , laz4android is support android
x86 compiled ok.
I think maybe when the Laztoapk build the APK file, it's not include
x86 folder into the android APK file.
please try use the attachments(build_debug_apk_new.bat) to build the
APK file.

Best regards!

Hello Handoko,

did you look at the sourcecode of laztoapk?
You try to use laztoapk to build x86 android apps. This is not
supported by laztoapk.
I would need to change things in laztoapk.
If you look at the code
http://sourceforge.net/p/laztoapk/svn/HEAD/tree/trunk/source/apkmanage
rmain.pas#l965
and search for "CopyNDKFilesToFPC" you will see that laztoapk copies
only arm -stuff from the ndk folder into the  laz4android folder.

Hello truetom,
thanks for you effort with laz4android.

Could you please add the package "CustomDrawn" to laz4android?

Thank you,

Thanks all for the helps and suggestions. But unfortunately, the
result is same: "Unfortunately, Project1 has stopped."

Although, I'm still not able to produce correct APK for Android Intel
64-bit, here I post all the things I found. Hope it would be useful
for someone who is willing to try and for LazForApk/laz4Android future
improvement.

Quote1. Extract the apk and see if the file structure is correct.
Under the unzipped directory, there is a "lib" folder and there should
be 2 sub-folders(armeabi & x86) in "lib". Check if the files in those
2 sub folders correspond to the CPU structure.
I now able to produce x86 only and fat binaries (armeabi & x86). But
the code just won't run on my phone. It make me think that the problem
wasn't my failure to create x86 lib in the apk file.

On my previous attempts, I failed to build x86 lib in the apk file
because of 2 reasons:

1. On the Lazarus - Project Settings, I didn't notice that I have to
change "android\libs\armeabi\liblclapp" to
"android\libs\x86\liblclapp" on the Path > Target File Name setting.
It caused the result file (x86 code) to be saved in the folder named
armeabi.

2. The script file "build_debug_apk.bat" generated by LazForApk
contain hardcoded text "armeabi" but without "x86". So I have to
manually added the text "x86".

Quote2. Write a simplest "Hello World" test app to see whether it
works. If it works, maybe there's something wrong in your code?
I didn't write my own code for the tests. But I used the default test
project generated by LazForApk. So it makes me think that perhaps the
default test project generated by LazForApk or the Custom Drawn
package might ever call any function that is only for arm machines,
which is not compatible with Intel 64-bit.

QuoteLibrary Path:
$(LazarusDir)\Android_NDK\platforms\android-9\arch-x86\usr\lib;
$(LazarusDir)\Android_NDK\toolchains\x86-
4.8\prebuilt\windows\lib\gcc\i686-linux-android\4.8

and no Custom Options.

Maybe you missed my second library path.
I have tested with the second library path added + with/without custom
options. I also have tried with:
- ...\platforms\android-9\...
- ...\platforms\android-16\...
- ...\toolchains\x86-4.8\...\i686-linux-android\4.8
- ...\toolchains\x86-4.8\...\i686-linux-android\4.9

QuoteI think it's not laz4android problems , laz4android is support
android x86 compiled ok.
I think maybe when the Laztoapk build the APK file, it's not include
x86 folder into the android APK file.
please try use the attachments(build_debug_apk_new.bat) to build the
APK file.
Thank you truetom for the new script file. It can't run, but I managed
to fix it by changing the paths to mine. Also there was one missing
file on this 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 REM Convert
the java bytecode to dalvik bytecodecall java
-Djava.ext.dirs=%ANDROID_HOME%\platform-tools\lib\ -jar
%ANDROID_HOME%\platform-tools\lib\dx.jar --dex --verbose
--output=%APK_PROJECT_PATH%\bin\classes.dex
%APK_PROJECT_PATH%\bin\classes
The code above (in build_debug_apk_new.bat) need to be changed to:

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 REM DX to
convert the java bytecode to dalvik bytecodecall java
-Djava.ext.dirs=%ANDROID_HOME%\platform-tools\lib\ -jar
%ANDROID_HOME%\build-tools\%SDK_BUILDTOOLS%\lib\dx.jar --dex --verbose
--output=%APK_PROJECT_PATH%\bin\classes.dex
%APK_PROJECT_PATH%\bin\classes
The difference is the file "..\lib\dx.jar" should not be be located
under "...\platform-tools" because there no such file in that
location. It works if I changed it to "...\build-
tools\%SDK_BUILDTOOLS%\lib\dx.jar"

Now the new script file is able to run correctly.

Quotedid you look at the sourcecode of laztoapk?
You try to use laztoapk to build x86 android apps. This is not
supported by laztoapk.
I would need to change things in laztoapk.
If you look at the code
http://sourceforge.net/p/laztoapk/svn/HEAD/tree/trunk/source/apkmanage
rmain.pas#l965
and search for "CopyNDKFilesToFPC" you will see that laztoapk copies
only arm -stuff from the ndk folder into the  laz4android folder.
Yep, I had already noticed it and tested to copy the x86 version of
NDK files before you told me. But I just re-performed the test again
with combining all the suggestions (as I mentioned above), but still
got the same error.

Can anyone tell me, my phone is Intel Atom 64-bit, is it able to run
code that compiled by Lazarus with Intel I386 setting? Or must I
change the Lazarus Target CPU Family setting to x86_64? I tried to
change it to x86_64, but it can't because it hasn't cross compile to
that target.

Those above are what I found so far, hope it can be useful for others.

Excuse me....

Did somebody encounter library problem with latest 3 versions of
Laz4Android?

The following code works fine with previous version, but with recent 3
versions it compiles but crashs when running on Android 2.3.3(API10).

Did FPC changes something with JNI  rule?

-- FPC code --
library testjni;

{$mode objfpc}{$H+}

uses
  JNI;

Function MyAdd(Env: pJNIEnv;this:JObject;a,b:JDouble):JDouble;Cdecl;
begin
Result:=a+b;
end;

Function JNI_OnLoad(VM: PJavaVM;Reserved: Pointer):JInt;Cdecl;
begin
Result:=JNI_VERSION_1_4;
end;

Procedure JNI_OnUnload(VM: PJavaVM;Reserved: Pointer);Cdecl;
begin
end;

Exports

MyAdd name 'Java_Test_TestJNI_MyAdd',

JNI_OnLoad,
JNI_OnUnLoad;

begin
end.

-- Java code --
package Test;
public class TestJNI {
        static
        {
                System.loadLibrary("testjni");               
        }
               
        public static native double MyAdd(double a, double b);
}
--
Project Options:
Libraries path setup
$(LazarusDir)\Android_NDK\platforms\android-8\arch-arm\usr\lib

Do I miss anything?

Thanks for your kindly help.

OKay, I found where the problem is. I use another computer(my laptop
is too old to run modern Android) to run the simulator of Android
4.3.1(API 18, armeabi-v7a) and everything become so smooth. The
previous test I did is with Android 2.3.3.(API10, armeabi)

But here comes another big question mark. Will the later FPC no longer
support old Android version(2.X) or armeabi architecture? For my app,
some users still hold a smartphone over 5 years!(such like moto defy)
If those old versions will be unsupported, it really could be a big
issue for me. Maybe temporarily I would still use the Laz4Android
released in July, 2015.

Hello ChenYuChih,
OK , now I build a FPC 4in1 rapid update package:
http://sourceforge.net/projects/laz4android/files/FreePascal/

I think it's fixed your problem.

For an explanation of FPC 4in1 updates:
This update package is used to replace the FPC of laz4android entire
folders, rapid upgrade FPC compiler, so don't need to download and
install the laz4android again, in order to achieve the purpose of
rapid upgrade laz4android.
Note that after replacement, please execute the batch file create-
fpc.cfg.bat.

Thanks and best regards!

Hello truetom,

thank you for fixing / maintaining laz4android!

I am preparing a new bundle of laztoapk.
The installer of laztoapk downloads the latest laz4android from
sourceforge.net  http://sourceforge.net/p/laztoapk/svn/HEAD/tree/trunk
/install/laztoapk.iss

Now you created a "FPC 4in1 rapid update package" for laz4android.
Question: Will you integrate this into RC3 or do I need to change my
install script and download both files?

Regards,
Sam

----------------------------------------------------------------------
truetom · 2015-10-31 07:56

Hello DelphiFreak,

Sure , I will continue update laz4android installer and 7z file.
When the FPC 3.0.0 rc3 or FPC 3.0.0 official version is release , I
will test it and update laz4android too.
But now I think release a rapid upgrade package for laz4andorid which
can save more time and quick response.

about laztoapk ,  I think we can wait FPC 3.0.0 rc3 or official
release .
I am waiting too.

Thanks and best regards!

Hi,
I just want to let you know ...
I played around for some time now to see if I get an app running on
Android 5, but had no success.
After removing all CustomDrawn components and units from my example
project, it worked.

So there must be a problem with CustomDrawn and Android 5.

the problem.

Maybe somebody has proper solution for that ?

Nice to see the project is still alive.

I must find time to test this and enter in the Android world.  Cordova
looks too much big and JavaScript isn't a nice language.  Sart Mobile
Studio seems nice since it allows both mobile and web apps, but I
didn't like how it works when I tested it (didn't test version 2.0
though).
