AdjustVolume is an Android app that I created to demonstrate the different ways by which you can interact with the AudioManger features of Android. The app currently supports the following features.
- Increase Volume
- Decrease Volume
- Play next Song
- Play previous Song
- Get the trackname of the currently playing song
Explanation/documentation of the source code can be found in the following blog posts.

Please note that the app currently tested only on HTC mobiles and with the default music player in other mobiles.
