// IMPORTANT!
// jw: graphics.pause is never called, graphics.pause works on most devices but not on all..
// for example on Samsung Galaxy Tab (GT-P6800) on android 4.0.4 invoking graphics.pause causes
// "Fatal Signal 11"
// near mEglHelper.swap() in GLSurfaceView while processing next onPause event.
// See related issue:
// http://code.google.com/p/libgdx/issues/detail?id=541
// the problem with graphics.pause occurs while using OpenGL 2.0 and original GLSurfaceView
// while rotating device in lwp preview
// in my opinion it is a bug of android not libgdx, even example Cubic live wallpaper from
// Android SDK crashes on affected devices.......... and on some configurations of android
// emulator too.
//
// My wallpaper was rejected on Samsung Apps because of this issue, so I decided to disable
// graphics.pause..
// also I moved audio lifecycle methods from AndroidGraphicsLiveWallpaper into this class
// graphics.pause();
// if (AndroidLiveWallpaperService.DEBUG) Log.d(AndroidLiveWallpaperService.TAG, " >
// AndroidLiveWallpaper - onPause() application paused!");
