Drawing a Bitmap using OpenGL is fairly trivial. (Granted they're power of 2.) (http://stackoverflow.com/questions/3553244/android-opengl-es-and-2d/3648054#3648054)
There already exists several android game engines for this task such as: http://www.andengine.org/ Google already provides GLSurfaceView to handle lifecycle changes. Even using the native android widgets along your game is trivial using GLSurfaceView. Shouldn't take you more than a day or so to make your own engine and build your game around it without any bloat and learning something in the process.
