How to restart video on Exoplayer after ExoPlayer.STATE_ENDED

This code works for me

 @OnClick(R.id.image_button_play)
public void play(){
    Log.d(TAG, "play: clicked");
    //If video has finished then set Exoplayer to 0
    if (simpleExoPlayer.getPlaybackState() == Player.STATE_ENDED){
        simpleExoPlayer.seekTo(0);
    }
    simpleExoPlayer.setPlayWhenReady(true);
    playButton.setVisibility(View.INVISIBLE);
}

I've updated the library to ExoPlayer r1.4.2 and it does the job...

    mPlayer.seekTo(0);
    mPlayer.setPlayWhenReady(true); // replay from start

// Pause video after restart

    mPlayer.seekTo(0);
    mPlayer.setPlayWhenReady(false);

A video can be seamlessly looped using a LoopingMediaSource. The following example loops a audio/video indefinitely. It’s also possible to specify a finite loop count when creating a LoopingMediaSource.

MediaSource source = new ExtractorMediaSource(audioUri, ...);
// Loops the audio indefinitely.
LoopingMediaSource loopingSource = new LoopingMediaSource(source);

or add a listener

playerExo.addListener(new ExoPlayer.Listener() {

            @Override
            public void onPlayerStateChanged(boolean playWhenReady, int playbackState) {

                switch(playbackState) {
                    case ExoPlayer.STATE_BUFFERING:
                        break;
                    case ExoPlayer.STATE_ENDED:
                        playerExo.seekTo(0);
                        break;
                    case ExoPlayer.STATE_IDLE:
                        break;
                    case ExoPlayer.STATE_PREPARING:
                        break;
                    case ExoPlayer.STATE_READY:
                        break;
                    default:
                        break;
                }
            }

            @Override
            public void onPlayWhenReadyCommitted() {

            }

            @Override
            public void onPlayerError(ExoPlaybackException error) {

            }
        });
        playerExo.seekTo(0);
        playerExo.setPlayWhenReady(true);//replay from start



/*  If you want to Pause audio/video and restart
 mPlayer.seekTo(0);
 mPlayer.setPlayWhenReady(false);*/
