Android – How to tell when MediaPlayer is buffering

Like below (API level ≥ 9):

mp.setOnInfoListener(new OnInfoListener() {

    @Override
    public boolean onInfo(MediaPlayer mp, int what, int extra) {
        switch (what) {
            case MediaPlayer.MEDIA_INFO_BUFFERING_START:
                loadingDialog.setVisibility(View.VISIBLE);
                break;
            case MediaPlayer.MEDIA_INFO_BUFFERING_END:
                loadingDialog.setVisibility(View.GONE);
                break;
        }
        return false;
    }
});

NOTE : There is a known bug in Android. When playing HLS stream it’s just never calls OnInfoListener or OnBuffering. check this link OnInfoListener bug
