I have noticed that a few members here are working on music related applications. I found a Google group for Android Music Developers.The groups main focus is on C# and Java related coding but many of the issues relating to Android SDK objects, classes and hardware problems are helpful.
Android Music Developers | Google Groups
Looking forward to seeing your music creations down the road.
