I had updated AndroidGraphicsLiveWallpaper class to match original AndroidGraphics as much as possible - I think in future releases all classes should be merged together:

AndroidGraphics
AndroidGraphicsLiveWallpaper
AndroidGraphicsDayream

I wanted to make it easier for you in the future. This " -> specific for live wallpapers" comments marks thinks allowing live wallpapers to work - differences between original AndroidGraphics class.
