This sample illustrates how to write an application that plays media in the background, handles streaming media from the network and reacts appropriately to system events like headphone disconnection and audio focus changes, and also uses the notification system to keep the user informed about what is happening. This CL is a cherrypick of the old CL 104495 (originally in honeycomb-mr1) into honeycomb-mr2. Original CL: https://android-git.corp.google.com/g/#change,104495 Change-Id: Ib8b15ee920300adc093a8b52c17bd9c251ac74ca
