             MediaSession, prior to API 21, uses a broadcast receiver to communicate with a
             media session. It does not have to be this broadcast receiver, but it must
             handle the action "android.intent.action.MEDIA_BUTTON".

             Additionally, this is used to resume the service from an inactive state upon
             receiving a media button event (such as "play").
