видео не воспроизводится, когда мы поворачиваем Relativelayout, содержащий Exoplayer

У меня есть активность, содержащая Exoplayer. он отлично работает, если у нас есть видео в относительном макете, но когда мы поворачиваем относительный макет, он не воспроизводит видео, как это можно сделать

вот код действия

public class ExoplayerAct extends Activity implements VideoRendererEventListener {


    private static final String TAG = "MainActivity";
    private SimpleExoPlayerView simpleExoPlayerView;
    private SimpleExoPlayer player;
    private TextView resolutionTextView;
    String j;
    RelativeLayout mainlayoutexo;
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.exoplayer);
        resolutionTextView = new TextView(this);
        //resolutionTextView = (TextView) findViewById(R.id.resolution_textView);

        Intent iin = getIntent();
        Bundle b = iin.getExtras();
        if (b != null) {
            j = (String) b.get("fileVideoPath");
        }

        mainlayoutexo   = (RelativeLayout) findViewById(R.id.mainlayoutexo);
        mainlayoutexo.setRotation(90);

// 1. Create a default TrackSelector
        BandwidthMeter bandwidthMeter = new DefaultBandwidthMeter();
        TrackSelection.Factory videoTrackSelectionFactory = new AdaptiveTrackSelection.Factory(bandwidthMeter);
        TrackSelector trackSelector = new DefaultTrackSelector(videoTrackSelectionFactory);

// 2. Create a default LoadControl
        LoadControl loadControl = new DefaultLoadControl();

// 3. Create the player.newSimpleInstance(RenderersFactory, TrackSelector, LoadControl).
        player = ExoPlayerFactory.newSimpleInstance(this, trackSelector, loadControl);
        simpleExoPlayerView = new SimpleExoPlayerView(this);
        simpleExoPlayerView = (SimpleExoPlayerView) findViewById(R.id.player_view);

//Set media controller
        simpleExoPlayerView.setUseController(true);

        simpleExoPlayerView.requestFocus();


// Bind the player to the view.
        simpleExoPlayerView.setPlayer(player);
        Uri mp4VideoUri = Uri.parse(j);





//Measures bandwidth during playback. Can be null if not required.
        DefaultBandwidthMeter bandwidthMeterA = new DefaultBandwidthMeter();
//Produces DataSource instances through which media data is loaded.
        DefaultDataSourceFactory dataSourceFactory = new DefaultDataSourceFactory(this
                , Util.getUserAgent(this, "exoplayer2example"), bandwidthMeterA);
//Produces Extractor instances for parsing the media data.
        ExtractorsFactory extractorsFactory = new DefaultExtractorsFactory();


// II. ADJUST HERE:

//This is the MediaSource representing the media to be played:
//FOR SD CARD SOURCE:
        MediaSource videoSource = new ExtractorMediaSource(mp4VideoUri, dataSourceFactory, extractorsFactory, null, null);

//FOR LIVESTREAM LINK:
//        MediaSource videoSource = new HlsMediaSource(mp4VideoUri, dataSourceFactory, 1, null, null);
        final LoopingMediaSource loopingSource = new LoopingMediaSource(videoSource);

// Prepare the player with the source.
        player.prepare(loopingSource);

Я просто хочу повернуть относительный макет, содержащий экзоплеер, как это можно сделать и воспроизвести видео с ним
