[SDL] Surface vs Texture - optimal usage

Hello,

I'm trying to create a very simple Android app by following the steps of the README-android.txt. Everything builds fine, and then I install the bin/SDLActivity-debug-apk (device and simulator). Once the app starts, it crashes shortly after.

With 'adb logcat' I found the following failure ...


Code:
W/dalvikvm(  734): No implementation found for native Lorg/libsdl/app/SDLActivity;.onNativeSurfaceChanged:()V
D/AndroidRuntime(  734): Shutting down VM
W/dalvikvm(  734): threadid=1: thread exiting with uncaught exception (group=0x41465700)
E/AndroidRuntime(  734): FATAL EXCEPTION: main
E/AndroidRuntime(  734): java.lang.UnsatisfiedLinkError: Native method not found: org.libsdl.app.SDLActivity.onNativeSurfaceChanged:()V


... which seems to miss the method onNativeSurfaceChanged().

I checked the my libraries in libs/armeabis (libSDL2.so + libmain.so) for onNativeSurfaceChanged but it's not there. Here a shortened log:

Code:
$ nm -D

00038cdd T Java_org_libsdl_app_SDLInputConnection_nativeCommitText
00038d09 T Java_org_libsdl_app_SDLInputConnection_nativeSetComposingText
...


That's where I'm lost. Any help is welcome.

thanks
