Question

I am working on ExoPlayer, I want to customize the ExoPlayer and listen for the Event next, previous, rewind, forward so that when the user clicks the next button next video

Answer 1

I use this link to customize the ExoPlayer for previous, next etc. You can implement your own logic to track all of these Events. It works for me.

Answer 2

 if you have not customized exoplayer



    if (currentPlayingVodPosition-1 == player.currentWindowIndex){
 Toast.makeText(this,"prev clicked",Toast.LENGTH_SHORT).show()

                    }
if (currentPlayingVodPosition+1 == player.currentWindowIndex){
   Toast.makeText(this,"next clicked",Toast.LENGTH_SHORT).show()

                    }

Answer 3

My approach

Assumed, we are already create collection of media source, DASH or HLS.

And using player view with SimpleExoPlayerView component. It will automatically have default control, prev, next, for example.

I handle collection of media source with current window index with this exoPlayer.getCurrentWindowIndex() to back and forth media source.

And you can check current index via this onTracksChanged method

@Override
public void onTracksChanged(TrackGroupArray trackGroups, TrackSelectionArray trackSelections) {

currentIndex = exoPlayer.getCurrentWindowIndex();

}

You can look this file for implementation these control.

Hope this help.

You might be able to add a ExoPlayer.Listener() and use constants from the PlaybackstateCompat class.

Override the onPlayerStateChanged listener and check the playbackState with rewind/fastforward/etc

 player.addListener(new ExoPlayer.Listener() {
            @Override
            public void onPlayerStateChanged(boolean playWhenReady, int playbackState) {
                if (playbackState == PlaybackStateCompat.STATE_FAST_FORWARDING) {
                    //do something                 
                }
                if (playbackState == PlaybackStateCompat.STATE_REWINDING) {
                    //do something else               
                }
            }

            @Override
            public void onPlayWhenReadyCommitted() {

            }

            @Override
            public void onPlayerError(ExoPlaybackException error) {
                mExoPlayer.stop();

            }
        });

Also:

1. STATE_SKIPPING_TO_NEXT
2. STATE_SKIPPING_TO_PREVIOUS
