Where can I find some good open source Android games to accelerate the learning process?

The code for my android game robotic space rock can be found here: http://code.google.com/p/monolithandroid

It is a block game with 3d opengl/es graphics, a highscore table, sound and midi music.

Here's a tip from someone who just started with Android games. The sample games that are in the SDK are good, however I've found it FAR easier (and better for learning) to start from scratch with a new Android Project rather than trying to modify an existing one. I ran into many dead ends using the "modify" approach. When I started from scratch I learned far more and got further faster with a blank slate.

Also, since you're not doing action games - don't get caught up in the games like JetBoy that use a thread to run the game loop. Threads certainly have their place, but if you're just learning they muddy the waters greatly.
