Hello All,

I’ve found two types of animation strategy. First, it is calling invalidate method within onDraw method of View subclass, like in Lunar Lander.
The second one is using a separate thread that generates messages to update view, like in A Bouncing Ball - Bacic Graphics Animation Demo example.
What is the best approach to implement animation? My application must react on the key pressing and currently implements the first strategy.
After pressing a key in series the screen continues updating, even I had stopped pressing it. OTOH the animation must be processed when no key is pressed.

Well Lunar Lander is shipped with the SDK from Google so you think they would promote best practices.
