Andengine Android Framework

If you are considering developing rich media applications on Android  games, make sure to look at Andengine 2D Open GL framework. It wraps the low level stuff and provides an excellent api for creating animations, sprites, effects and almost anything you can shake a stick at, it even has compatibility with TMX tile maps (TMX is a widely used format for designing tiled maps).

I used this framework for Warlock's Bounty on a low spec Orange San Francisco phone,  and it's been working admirably.
