Hi all,

I finally managed to compile and run some of the demo apps that come
with LAMW but they all crash on startup.
The error I get with logcat is

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 05-27
17:02:19.829 20017 20017 E JNI_Loading_libcontrols:
java.lang.UnsatisfiedLinkError:
dalvik.system.PathClassLoader[DexPathList[[zip file "/data/app/org.lam
w.appmenudemo2-
w3AxaKV6y57YUTD00uMpzg==/base.apk"],nativeLibraryDirectories=[/data/ap
p/org.lamw.appmenudemo2-w3AxaKV6y57YUTD00uMpzg==/lib/arm64,
/system/lib64]]] couldn't find "libcontrols.so"
I am compiling the project by manually launching the gradle-local-
run.sh script, but I'm clearly missing something since it cannot find
the libcontrols library.
Thank you!

hi, tango13!

Some hints

1) Go to lazarus menu  "Tools" --> "[LAMW]....." --->  "Paths
Settings"
and confirm that everything is correct ...

2) Create a new  LAMW project :  "Project"  --- "New Project" --->
"[LAMW] GUI ....."
 
3) Build the LAMW  "libcontrols.so"  library:  "Run"  --> "Clean up
and Build"

4) Connect some android device to your PC (or start some android
emulador/AVD)

5) "Run"  --> "[LAMW] Build Android Apk and Run"


If you were successful then Congratulations!!! Now you can try open
some LAMW demo:

1) Open a LAMW demo project
 
2) Build the LAMW  "libcontrols.so"  library:  "Run"  --> "Clean up
and Build"

3) Connect some android device to your PC (or start some android
emulador/AVD)

4) "Run"  --> "[LAMW] Build Android Apk and Run"

Hi Jose and thanks for your reply.
I did as you said, everything works up to point 2 of the demo project,
libcontrols is built but the project is not, the error is

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 Fatal:
Cannot find system used by controls. Make sure all ppu files of a
package are in its output directory. ppu in wrong
directory=D:\lamw_manager\LAMW\LAMW4Windows\fpc\3.2.0\units\arm-
android\rtl\system.ppu..
What is even worse is that now I can't compile anymore my projects,
the error is the same

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 Fatal:
Cannot find system used by fcllaz. Make sure all ppu files of a
package are in its output directory. ppu in wrong
directory=D:\lamw_manager\LAMW\LAMW4Windows\fpc\3.2.0\units\arm-
android\rtl\system.ppu..
but I didn't change anything in my project's paths.

I'm a little lost... 
Thank you.

Have you updated from lamw manager ?better use laz4android ,It run
smoothly

Yes, I reinstalled everything from scratch using lamw manager and now
it's back to work.
Unfortunately I mostly use Lazarus under Linux and as far as I
understand Laz4android is windows-only
Thank you.

Also, I'm trying to use the code in AppMenuDemo to create an option
menu but I don't seem to get anywhere, no menus show up.
Can anyone please shed some light on how to do it?
Thank you very much!

Making some progress, but if I try this 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.DataModuleCreateOptionMenu(Sender: TObject; jObjMenu:
jObject);var   i: integer;   //jSubMenu: jObject;begin   for i:=0 to
jMenu1.Options.Count-1 do   begin        //0:mitDefault; 1:misIfRoom 
     jMenu1.AddItem(jObjMenu, 10+i {itemID},
jMenu1.Options.Strings[i], mitDefault);   endend;
I get this error

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 JNI
DETECTED ERROR IN APPLICATION: bad arguments passed to void
org.lamw.magicspiral.jMenu.AddItem(android.view.SubMenu, int,
java.lang.String, int)
I am most likely doing something wrong, but what?

Thank you
