Made apk.


How did you do apk.
Which version you use Lazarus?

(the version here should be of the installed Windows compiler, not the version of the cross-compiler, so might be 2.6.0 or 2.7.1 or something else)

[roeug]

lazarus-1.0.2-fpc-2.6.0-win32
fpc4android_2_5_1_2_apr_2012.zip (\units\arm-linux; bin\i386-win32\ppcrossarm.exe and arm-linux-*.exe 2.5.1)

[Fortuna1]

Try with http://mirrors.iwi.me/lazarus/snapshots/

This is beter solutions.
mirrors.iwi.me/lazarus/snapshots/Lazarus-1.1-39124-fpc-2.7.1-20121018-win32.exe

[Fortuna1]

1) step
   Lazurs make   liblclapp.so
2) generate_debug_key
3) build_debug_apk  // make apk

3) IF compile  androidlcltest project  the name is androidlcltest.apk

copy androidlcltest.apk in your android


or 



start corect AVD emulator

I use android 2.2. API Level 8

[Fortuna1]

In execution I have "unfortunately <aap_name> has stopped
This is not done,

I think that you did not properly build apk.


You must get  name androidlcltest.apk and not unfortunately <aap_name>

Publish your console   of  build_debug_apk.bat.

I thing that you forget edit build_debug_apk.bat
Change correct  XXXXXXX

jarsigner -verbose -keystore bin\LCLDebugKey.keystore -keypass XXXXXX -storepass XXXXXX -signedjar bin\%APP_NAME%-unaligned.apk bin\%APP_NAME%-unsigned.apk LCLDebugKey



 use  correct user and password  generation with  generate_debug_key.

[roeug]

I tried Lazarus-1.1-39124-fpc-2.7.1-20121018-win32.exe but result is the same: emulator says "unfortunately <ap_name> has stopped [OK]"
I used
ppcrossarm.exe
 and
lazarus\fpc\2.5.1\units\arm-linux
from fpc4android_2_5_1_2_apr_2012.zip

ADDED:
Interesting that compiled apk  lazarus\examples\androidlcl\android\bin\androidlcltest.apk
gives the same "unfortunately <ap_name> has stopped [OK]"

From the log:

10-26 07:34:27.014: I/lclapp(20897): Trying to load liblclapp.so
10-26 07:34:27.054: E/lclapp(20897): WARNING: Could not load liblclapp.so
10-26 07:34:27.054: W/System.err(20897): java.lang.UnsatisfiedLinkError: Couldn't load lclapp: findLibrary returned null

Do you change the output filename (-o)? The .so name is hardcoded in the java wrapper.

[roeug]

"Do you change the output filename (-o)? The .so name is hardcoded in the java wrapper."
Sorry. What exactly have I to do (manually rename which file or what)?

[Leledumbo]

What exactly have I to do (manually rename which file or what)?

IF you change the output filename, then you can manually rename in android/libs/go/to/the/deepest/dir/libyourapp.so to liblclapp.so. Otherwise, change all instance of "lclapp" (don't really have to, but can avoid confusion) in LCLActivity.java (just search the file, I forget the location).

[roeug]

>The .so name is hardcoded in the java wrapper. ¬
  Got it.
> Do you change the output filename (-o)?
No, I am in trying to apk androidlcltest "as is" from ./examples (sure, with my paths and debug_key). Just no success in emulator

[Leledumbo]

Try this in your emulator, compiled on my machine.

[roeug]

It works
The sizes are LCLExample-debug.apk = 1386247, (my) androidlcltest.apk=1429764

[roeug]

Result LCL test installed and runs (at the moment with black screen)

Lazarus 1.02 FPC 2.6.0
1) fpc4android_2_5_1_2_apr_2012.zip
      *.exe -> …lazarusfpc260\fpc\2.6.0\bin\i386-win32 
units - > …lazarusfpc260\fpc\2.5.1\units\arm-linux
2) Project/Target file name (-o) WAS
android\libs\armeabi\liblclapp.so
MUST be
android\libs\armeabi\liblclapp (NO EXTENTION so)
3) Edit generate_debug_key.bat, build_debug_apk.bat - SET PATH…SET ANDROID_HOME…SET APK_SDK_PLATFORM….SET APK_PROJECT_PATH…
