toro ToroPlayer.EventListener not working

Hello, I'm trying to put thumbnails in my videos as in this example. I'm using ToroPlayer.EventListener but it does not seem to be working. How to fix this? Here is my ViewHolder code:

public class ViewHolderVideo extends RecyclerView.ViewHolder implements ToroPlayer,ToroPlayer.EventListener{

        ExoPlayerViewHelper helper;
        private Uri videoUri;
        private PlayerView videoPostagem;
        private ImageView thumbVideoPostagem;
        
        public ViewHolderVideo(@NonNull View itemView) {
            super(itemView);

            videoPostagem = itemView.findViewById(R.id.exoPostagem);
            thumbVideoPostagem = itemView.findViewById(R.id.thumbVideoPostagem);

        }
        @NonNull
        @Override
        public View getPlayerView() {
            return videoPostagem;
        }

        @NonNull
        @Override
        public PlaybackInfo getCurrentPlaybackInfo() {
            return helper != null ? helper.getLatestPlaybackInfo() : new PlaybackInfo();
        }

        @Override
        public void initialize(@NonNull Container container, @Nullable PlaybackInfo playbackInfo) {
            if (helper == null) {
                helper = new ExoPlayerViewHelper(this, videoUri);
            }
            helper.initialize(container, playbackInfo);
        }

        @Override
        public void release() {
            if (helper != null) {
                helper.release();
                helper = null;
            }
        }

        @Override
        public void play() {
            if (helper != null) helper.play();
        }

        @Override
        public void pause() {
            if (helper != null) helper.pause();
        }

        @Override
        public boolean isPlaying() {
            return helper != null && helper.isPlaying();
        }

        @Override
        public boolean wantsToPlay() {
            return ToroUtil.visibleAreaOffset(this, itemView.getParent()) >= 0.85;
        }

        @Override
        public int getPlayerOrder() {
            return getAdapterPosition();
        }

        @Override public void onFirstFrameRendered() {
            //posterView.setVisibility(View.GONE);
            Log.i("EventListener","onFirstFrameRendered");
        }

        @Override public void onBuffering() {
            Log.i("EventListener","onBuffering");
        }

        @Override public void onPlaying() {
            //posterView.setVisibility(View.GONE);
            Log.i("EventListener","onPlaying");
        }

        @Override public void onPaused() {
            //posterView.setVisibility(View.VISIBLE);
            Log.i("EventListener","onPaused");
        }

        @Override public void onCompleted() {
            Log.i("EventListener","onCompleted");
        }

    }
