You should use SurfaceView if there will be a limited number of sprites (~20 sprites). Otherwise, OpenGL is better for high-intensity graphics.
The SDK includes some game samples and I recommend that you start with those. The Lunar Lander example is especially good and is a complete, real-time game. It has a game loop, 2 threads (UI thread + drawing thread), and some basic game states. If this is your first time creating a game, I would also recommend that you learn some of the fundamentals of building a game, such as game loops. I'm sure you can find some good resources with a Google search. On Nov 1, 2:18 pm, klirr <[email protected]> wrote: > It is way to slow and in the first example it doesnt even move.
