title: How to catch all errors for ExoPlayer?
body: <p>I implemented ExoPlayer as player for my application. But I can´t find out how to catch all ExoPlayer errors to avoid app crash. I added following listener, but it doesn´t catch all errors.</p>
  <p>I have to use DRM and it sometimes crash on some problem with it, but I can´t set listener before, because player is NULL.</p>
  <pre class="lang-java prettyprint-override"><code>player = ExoPlayerFactory.newSimpleInstance(context, trackSelector, loadControl, drmSessionManager);
  
  player.addListener(new ExoPlayer.EventListener() {
      @Override
      public void onTimelineChanged(Timeline timeline, Object manifest) {
  
      }
  
      @Override
      public void onTracksChanged(TrackGroupArray trackGroups, TrackSelectionArray trackSelections) {
  
      }
  
      @Override
      public void onLoadingChanged(boolean isLoading) {
  
      }
  
      @Override
      public void onPlayerStateChanged(boolean playWhenReady, int playbackState) {
  
      }
  
      @Override
      public void onPlayerError(ExoPlaybackException error) {
      //Catch here, but app still crash on some errors!
      }
  
      @Override
      public void onPositionDiscontinuity() {
  
      }
  });
