title: ExoPlayer Seek Start and Seek End events
body: <p>I implemented the AnalyticsListener interface and I'm listening "onSeekStarted" and "onSeekProcessed" events.</p>
  
  <p>In ExoPlayer when I start seeking I don't get any event. When I release the slider I get the "onSeekStarted", then the video recalculates the position and when the video starts playing again from the new position, I get the "onSeekProcessed". This is not what I need.</p>
  
  <p>What I need is an event when the user starts seeking the slider (Seek Start) and one more event when the user releases the slider (Seek End). Is there any way to achieve it with ExoPlayer ?</p>
  
  <p>I'm using ExoPlayer 2.9</p>
