Minimal code to play Youtube Video - Android

Below given is the simple code snippet to play a video. 

public class YoutubePlayerActivity extends YouTubeBaseActivity implements YouTubePlayer.OnInitializedListener {

    

    @Override

    protected void onCreate(Bundle savedInstanceState) {

        super.onCreate(savedInstanceState);

        setContentView(R.layout.activity_youtube_player);

        playYouTubeVideo();

        

    }

    

    private void playYouTubeVideo()

    {

        YouTubePlayerView youTubeView = (YouTubePlayerView) findViewById(R.id.youtube_view);

        youTubeView.initialize("DummyKeyIzaSyBgURIAyTk3EklVgbtbiqN2Qw", this);

    }

    

    public void onInitializationFailure(YouTubePlayer.Provider provider,

                                        YouTubeInitializationResult errorReason) {

        AppUtils.errorLog("Player initialization failure!");

    }

    

    @Override

    public void onInitializationSuccess(YouTubePlayer.Provider provider, YouTubePlayer player,

                                        boolean wasRestored) {

        if (!wasRestored) {

            player.cueVideo("wKJ9KzGQq0w");

            player.play();

        }

    }

}

The player.play sometimes does not play it automatically. In that case, just call loadVideo instead of cueVideo or playVideo.
