title: Build Play Music-like interface
body: <p>I'm trying to build and interface that would mimic the recent Google Play Music interface which as a reminder looks like this on a phone</p>

  <p>I've already got the <code>DrawerLayout</code> and the Tabs right, but I have no idea how to build the amazing bottom fragment that displays the currently playing song. It mixes two features:</p>
  
  <ul>
  <li>If you swipe this fragment to the left, it will be replaced by the next song. i think it can be done fairly quickly using a <code>ViewPager</code> and a new <code>Fragment</code>for each song, but is it an efficient way to do it?</li>
  <li>If you swipe it up, it will open kind of a drawer containing the player itself (see the above second and third screenshots). How can I get something similar inside my application? I can't find any mention of this inside the docs so I guess it's not really official.</li>
  </ul>
