ExoPlayerのエラーをすべて捕まえるには？

Question

私はExoPlayerを自分のアプリケーションのプレーヤとして実装しました。しかし、アプリクラッシュを避けるためにExoPlayerのすべてのエラーを捕まえる方法を見つけることはできません。次のリスナーを追加しましたが、すべてのエラーをキャッチしません。

私はDRMを使用する必要がありますが、それはいくつかの問題でクラッシュすることがありますが、プレーヤーがNULLなので前にリスナーを設定できません。

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() { 

     } 
    });

おかげで、これはすべての問題をカバーする必要があります。

@Override 
    public void onPlayerError(ExoPlaybackException error) { 
     switch (error.type) { 
      case ExoPlaybackException.TYPE_SOURCE: 
       Log.e(TAG, "TYPE_SOURCE: " + error.getSourceException().getMessage()); 
       break; 

      case ExoPlaybackException.TYPE_RENDERER: 
       Log.e(TAG, "TYPE_RENDERER: " + error.getRendererException().getMessage()); 
       break; 

      case ExoPlaybackException.TYPE_UNEXPECTED: 
       Log.e(TAG, "TYPE_UNEXPECTED: " + error.getUnexpectedException().getMessage()); 
       break; 
     } 
    }
