import android.os.Bundle;

import android.view.Window;

import android.view.WindowManager;

import android.widget.Toast;

import com.google.android.youtube.player.YouTubeBaseActivity;

import com.google.android.youtube.player.YouTubeInitializationResult;

import com.google.android.youtube.player.YouTubePlayer;

import com.google.android.youtube.player.YouTubePlayerView;

public class TeachingVideos   extends YouTubeBaseActivity implements  YouTubePlayer.OnInitializedListener {

    private static final int RECOVERY_DIALOG_REQUEST = 10;

    public static final String API_KEY = "API KEY HERE";

    private String VIDEO_ID1 = "AeaFlRkWHrs";

                   String val;

    @Override

    protected void onCreate(Bundle savedInstanceState) {

        requestWindowFeature(Window.FEATURE_NO_TITLE);

        super.onCreate(savedInstanceState);

        setContentView(R.layout.activity_teaching_videos);

        getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN,

                WindowManager.LayoutParams.FLAG_FULLSCREEN);

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

        youTubeView.initialize(API_KEY, this);

    }

     private void showMessage(String message) {

        Toast.makeText(this, message, Toast.LENGTH_LONG).show();

    }

    @Override

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

        if (!b) {

                 youTubePlayer.cueVideo(VIDEO_ID1);

    

         }

    }

    @Override

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

        if (youTubeInitializationResult.isUserRecoverableError()) {

            youTubeInitializationResult.getErrorDialog(this, RECOVERY_DIALOG_REQUEST).show();

        } else {

            String errorMessage = String.format("YouTube Error (%1$s)",

                    youTubeInitializationResult.toString());

            Toast.makeText(this, errorMessage, Toast.LENGTH_LONG).show();

        }

    @Override

    protected void onActivityResult(int requestCode, int resultCode, Intent data) {

        if (requestCode == RECOVERY_DIALOG_REQUEST) {

            // Retry initialization if user performed a recovery action

            getYouTubePlayerProvider().initialize(API_KEY, this);

        }

    }

    protected YouTubePlayer.Provider getYouTubePlayerProvider() {

        return (YouTubePlayerView) findViewById(R.id.youtube_view);
