I have found this code here [how to view youtube list of a specific playlist?

I have added the YoutubeAndroidPlayerAPI.jar, but it doesn't play it says 'An Error occurred while initializing the YouTube Player'
I don't know what is wrong here..
Please help me

My Java Code

public class MainActivity extends YouTubeBaseActivity implements YouTubePlayer.OnInitializedListener {





public static final String API_KEY = "API KEy";

//http://youtu.be/<VIDEO_ID>

public static final String VIDEO_ID = "PlayList ID";



public void onFullscreen(boolean isFullscreen) {

    if (isFullscreen)

        playbackEventListener.onPlaying();

}

@Override

protected void onCreate(Bundle savedInstanceState) {

    super.onCreate(savedInstanceState);

    setContentView(R.layout.activity_main);

    /** Initializing YouTube player view **/

    YouTubePlayerView youTubePlayerView = (YouTubePlayerView) findViewById(R.id.youtube_player);

    youTubePlayerView.initialize(API_KEY, this);





}



@Override

public void onInitializationSuccess(YouTubePlayer.Provider provider, final YouTubePlayer youTubePlayer, boolean b) {

    /** add listeners to YouTubePlayer instance **/

    youTubePlayer.setPlayerStateChangeListener(playerStateChangeListener);

    youTubePlayer.setPlaybackEventListener(playbackEventListener);

    youTubePlayer.setOnFullscreenListener(new YouTubePlayer.OnFullscreenListener() {

        @Override

        public void onFullscreen(boolean c) {

            if(c)

                youTubePlayer.play();

            else

                youTubePlayer.play();

        }

    });





    /** Start buffering **/

    if (!b) {



        youTubePlayer.loadPlaylist(VIDEO_ID);





    }

}



@Override

public void onInitializationFailure(YouTubePlayer.Provider provider, YouTubeInitializationResult youTubeInitializationResult) {

    Toast.makeText(this, "Failured to Initialize!", Toast.LENGTH_LONG).show();

}

private YouTubePlayer.PlaybackEventListener playbackEventListener = new YouTubePlayer.PlaybackEventListener() {







    @Override

    public void onBuffering(boolean arg0) {

    }



    @Override

    public void onPaused() {

    }



    @Override

    public void onPlaying() {

    }



    @Override

    public void onSeekTo(int arg0) {

    }



    @Override

    public void onStopped() {

    }



};





private YouTubePlayer.PlayerStateChangeListener playerStateChangeListener = new YouTubePlayer.PlayerStateChangeListener() {



    @Override

    public void onAdStarted() {

    }



    @Override

    public void onError(YouTubePlayer.ErrorReason arg0) {

    }



    @Override

    public void onLoaded(String arg0) {

    }



    @Override

    public void onLoading() {

    }





    @Override

    public void onVideoEnded() {

    }



    @Override

    public void onVideoStarted() {

    }

};

}
