/**
 * A sample showing how to use the ActionBar as an overlay when the video is playing in fullscreen.
 *
 * The ActionBar is the only view allowed to overlay the player, so it is a useful place to put
 * custom application controls when the video is in fullscreen. The ActionBar can not change back
 * and forth between normal mode and overlay mode, so to make sure our application's content
 * is not covered by the ActionBar we want to pad our root view when we are not in fullscreen.
