title: How can I add persistent media controls like Apollo or Google music
body: <p>I would like to add music controls such as play/pause, next, and back as well as show a thumbnail and song title to the bottom of an application like in the Google music app.<br>

  When the thumbnail or title is tapped on, I want to bring up a detailed view of song, including a seek bar.<br>

  I am wondering what the best approach for this would be.  Should I just add a relative layout the the bottom of my apps xml, and add on click listeners, or can this be accomplished simply with something like the MediaController class?</p>
