LAMW problems
lazarus / 43-Android

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

I'm having problems with building android projects. Sorry for my
ignorance when it comes to this. I'm an FPC newbie.

 I'm using the following,

Lazarus 1.4.4 r49931 FPC 3.0.0 i386-win32-win32/win64
LAMW downloaded from here,
https://github.com/jmpessoa/lazandroidmodulewizard/archive/master.zip
Android-ndk-r10e
Android sdk
Apache-ant-1.9.6

First, when attempting to create an onClick event (by double clicking
a button in the design view) I receive an error.

"TDefaultComponentEditor has created the error:
Unable to find method...

androidwidget.pas(15,51) Error: unit not found: CustApp

If I restart the IDE this error disappears. No big deal really it's
just odd.

The biggest problem I have is dealing with paths and include files. I
dropped a listview, dbf and a button on a form. I set the dbf to a
table and set the button onclick event to display data in the
listview. When I try and build the application I get multiple "Cannot
find unit XYZ" errors. The IDE finds the units but the compiler does
not so I assume it's a problem with the FPC.cfg file.

Adding a path in the project options does nothing. Btw, when adding
C:\Android\laz4android\fpc\3.0.0\source\packages\gtk2\src\gtk+\gtk in
the project options it complains about unusual characters. I suppose
it's the + sign.

error example...
gtk2cellrenderer.pas(30,3) Fatal: Cannot find unit gtk2 used by
Gtk2CellRenderer of package LCL.

If I add a path to the fpc.cfg file they are found. Here is a list of
the units not found,

gtk2, glib2, atk, pango, gdk2pixbuf, gdk2, Cairo, xlib, gdk2x, gtk2ext

Here is what I added to the fpc.cfg file.

-FuC:\Android\laz4android\fpc\3.0.0\source\packages\gtk2\src\gtk+\gtk
-FuC:\Android\laz4android\fpc\3.0.0\source\packages\gtk2\src\glib\
-FuC:\Android\laz4android\fpc\3.0.0\source\packages\gtk2\src\atk\
-FuC:\Android\laz4android\fpc\3.0.0\source\packages\gtk2\src\pango\
-FuC:\Android\laz4android\fpc\3.0.0\source\packages\gtk2\src\gtk+\gdk-
pixbuf\
-FuC:\Android\laz4android\fpc\3.0.0\source\packages\gtk2\src\gtk+\gdk\
-FuC:\Android\laz4android\fpc\3.0.0\source\packages\cairo\src\
-FuC:\Android\laz4android\fpc\3.0.0\source\packages\x11\src\
-FuC:\Android\laz4android\fpc\3.0.0\source\packages\gtk2\src\gtk2x11\
-FuC:\Android\laz4android\fpc\3.0.0\source\packages\gtk2\src\gtkext\

Is there a way to recursively look in subdirectories rather than
entering so many paths?

Now the app will build and install on an emulator. Unfortunately, it
stops before it starts.

I attempted to upgrade the code templates for the project to see if
this would help. The .java files update fine. The controls.lpr cause
an access violation. If I choose to cancel Lazarus finally crashes and
needs to be terminated.

Sorry for such a long winded post. I just wanted to give as much
information as possible in the event they all are related.

Thanks in advance!

Hello zorfox!

1.

Quote I'm using... Lazarus 1.4.4 r49931 FPC 3.0.0
i386-win32-win32/win64

[yes, you can prepare your own Lazarus to  "cross-compile" ...]

But, please, get "Laz4Android" from here:

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

[EDITED: Ok, you have "Laz4Android!"]

2.

Quote..I dropped a listview, dbf and a button on a form....

Go to IDE menu "Project" -->> "New Project" -->> "JNI Android Module
[Lamw GUI]"
to create a cross android project... and, please, use "Android
Bridges" and "Android Bridges Extra" components... not listview, dbf
and a button, etc..

You can see "readme_get_start.txt" ....

Thanks for the quick reply!

I think I did download the IDE from that link.

http://iweb.dl.sourceforge.net/project/laz4android/laz4android1.4.4-
FPC3.0.0.exe

Is this not correct?

As far as the components I was using items from the android bridge.
The listview was jListView1 and the button jButton1. Should I not use
TDbf? Instead use jSqliteDataAccess from the bridges component
palette? I will have to figure out how to use the sqlLite components.
Otherwise, I would have tested it already.

Overall, I need to use only components from the android brides?

Yes, but pure "FCL" [not LCL dependent] component  can be used, too...
[well, "LCLBase" dependency is ok,  need to get component resource
icon...]
