Tests/Demos: Activities onPause / onResume has to call mGLSurfaceView.onPause()/.onResume;

[GoogleCodeExporter]

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.
