API Demos

The samples folder of the Android SDK holds the source code for the API Demos app, which demonstrates how to use various Android APIs via small, digestible, working examples. You can find tons of simple, straight-to-the-point examples in the API Demos source code. Incorporating animation into your project or playing an audio file inside your app is easy because API Demos provides examples of both. If you have a lot of ideas but not a lot of time, you should definitely install this demo app on your device and play with its numerous examples to see exactly what they can do.
