When the Activity is paused or resumed it also has do be forwarded to the GLSurfaceView.

Fix in all Examples/Tests:

@Override public void onPause() { super.onPause(); mGLSurfaceView.onPause(); Director.sharedDirector().pause(); }

@Override
public void onResume() {
    super.onResume();
    mGLSurfaceView.onResume();
    Director.sharedDirector().resume();
}

Suggestion: Create a Cocus2dActivity that encapsulates GLSurfaceView (and maybe a PowerManager.WakeLock)

I've done some testing with and without the mGLSurfaceView.onPause() / mGLSurfaceView.onResume() and found that including these lines can cause problems.

After locking the screen (hangup button), then waking, the texture maps seem to get scrambled (eg sprites show the wrong texture, or white boxes) sometimes followed by a silent crash of the Activity (eg, no force close, Activity just dies as if the back button were pressed). Removing the mGLSurfaceView.on* lines resolves the problem.

I see this behavior on the Android 2.2 (and 1.6) emulator, using svn r105 of cocos-android. Curiously, on a real device running Android 2.2 the texture scrambling bug always occurs upon locking/unlocking the screen, irrespective of explicitly setting the state of mGLSurfaceView. Anyone have any ideas why this is happening ?

The symptoms described here are similar to those described in Issue 23. I suspect it's the same bug.

Hi,

I have a white screen each time the application resume (multi-task). Adding mGLSurfaceView.onPause(); and mGLSurfaceView.onResume(); do not change anything.

I use an HTC desire 2.1 Is there an existing fix for this bug ?

@dringapp thats a normal openglsurface context loss. all resources(textures,vbo) have to be reloaded in this case. this should be handled by the engine. so a suggest you open a new issue.
