If you're interested in developing a game for the Android platform, there is a lot you need to know.  I'm the developer of Light Racer, Light Racer 3D, Antigen, Deadly Chambers and Wixel, which are currently available on the Android Market.  I've developed games before but the original Light Racer was my first Android application and I learned quite a bit about writing Android games that I'd like to share with everyone.  I even wrote an online book detailing the development of Light Racer 3D, which is full of how-tos and useful code snippets. If you have previous experience with game development, moving over to the mobile platform won't be all that difficult.  You will mostly just need to learn the architecture and API.  If you're new to game development, I have assembled a list of must-knows for getting started.  They apply to many different types of games, including action, strategy, simulation and puzzle.

The Android API is very well designed with regards to application integration and general mobile use.  I think google did an awesome job with the architecture.  The Activity/Intent/Application model is very well though out and allows for some nice "piggybacking" of one app onto another for extended functionality.  I like the layouts and views a lot.  They gave us a SurfaceView to do double-buffering of drawable area on screen and they even gave us an OpenGL 1.3 implementation.  What about sound?  The Android sound API seems to have taken a back burner for the latest 1.0 release.
