If you are drawing your app using standard Views and Canvas, this is not required. If you are using SurfaceView.lockCanvas(), make sure to check the returned Rect. It tells you what part of the the Canvas you *have* to redraw (this will take into account previous frames.) If you always draw what intersects this Rect you won't have any problem.
