As a developer it is important to learn from others as well as share your knowledge. The two most popular Android groups that I would recommend for learning and sharing are the Google Android Beginners Group and the Android Developers Group:Here are the links:
Android Beginners Group
Android Developers Group
And, if you would like to stay up to date on all things Android you will likely find that in the Discussion Group.
All of my Android Development Video Tutorials are available here on my blog with additional notes and comments that you may find helpful.
I look forward to your comments and input.
