Listeners (ExoPlayerListener ,VideoControlsSeekListener,OnBufferUpdateListener, OnSeekCompletionListener) are not getting called

Include the following:

ExoMedia version: 4.2.1
Device OS version: 8.0
Devide Manufacturer: Hongkong based company
Device Name: Infinix hot s3

I have implemented interfaces like ExoPlayerListener ,VideoControlsSeekListener,OnBufferUpdateListener, OnSeekCompletionListener in my android app. But it's not getting called in any scenarios in the implemented methods below.

These are methods above interfaces implements

  @Override
    public void onSeekComplete() {
        Log.d(TAG, "On Seek Complete");
    }

    @Override
    public void onBufferingUpdate(int percent) {
        Log.d(TAG, "Buffering % "+ percent);

    }

    @Override
    public boolean onSeekStarted() {
        Log.d(TAG, "on seek started");
        return false;
    }

    @Override
    public boolean onSeekEnded(long seekTime) {
        Log.d(TAG, "on seek end");
        return false;
    }

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

        Log.d(TAG, "On state change");
    }

    @Override
    public void onError(ExoMediaPlayer exoMediaPlayer, Exception e) {
        Log.d(TAG, "On error");
    }

    @Override
    public void onVideoSizeChanged(int width, int height, int unAppliedRotationDegrees, float pixelWidthHeightRatio) {
        Log.d(TAG, "on video size changed");
    }

But non of the above log gets printed.

Reproduction Steps

1. This line of code videoView.seekTo(stopPosition+resumeTime-pausedTime); does not call any of the above impmented methods of listeners interfaces but video seeks work(Current video playing time gets increases )
2. When video is frozen due to low internet and restart after few seconds
3. When coming from background to foregound , video freeze for few second then video restart

Expected Result

In all above three cases ,neither of the implmented methods of above interfaces /listeners gets called.

Actual Result

Listeners are not working as expected

How are you registering the listeners? Some of them (e.g. ExoPlayerListener) are used internally so would be more difficult to register and would break some other functionality by overwriting an expected listener. We should be using the listeners under com.devbrackets.android.exomedia.listener.*. As far as the rebuffering goes, see #102
