Creating a New Project

Google Developer Console

Go to https://console.developers.google.com/ and create a new project for your current application.

Enable Youtube Data API and Create API Key

After that, in the library section and click the youtube data API to enable it, then go to Credentials create an API key.

You will get an API Key. eg

Restrict API Key (Optional)

This is security purpose to let your API key access to specific application. So the hacker will not able to use your API key easily.

• Create KeyStore, (Toolbar > Build > Generate Signted APK > Create New Button)
  
  
• By enter “keytool -list -v -keystore (keystore location)” to Get SHA-1 signing-certificate fingerprint to restrict usage to your Android apps.

• Submit your project package name and SHA-1 fingerprint in the Google Developer Console.

Create two Activities

    android:layout_width="match_parent"
    android:layout_height="match_parent" />

Edit YoutubeActivity.java class

Go to this class and extends YoutubeBaseActivity and implement YoutubePlayer.OnInitializedListener.

public class YoutubeActivity extends YouTubeBaseActivity implements YouTubePlayer.OnInitializedListener {


    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);

        setContentView(R.layout.activity_youtube);

        YouTubePlayerView youTubePlayerView = (YouTubePlayerView) findViewById(R.id.youtube_player_view);
        youTubePlayerView.initialize(MainActivity.API_KEY, this);

    }

    @Override
    public void onInitializationFailure(YouTubePlayer.Provider provider, YouTubeInitializationResult result) {
        Toast.makeText(this, "Failed.", Toast.LENGTH_LONG).show();
    }

    @Override
    public void onInitializationSuccess(YouTubePlayer.Provider provider, YouTubePlayer player, boolean wasRestored) {
        if(null== player) return;
        if (!wasRestored) {
            player.loadVideo(MainActivity.VIDEO_ID);
        }

        player.setPlayerStateChangeListener(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() { }
        });


        player.setPlaybackEventListener(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() { }
        });
    }
}

Edit YoutubeFragment.java class

Modify this java class and add fragment in this class. Follow the source code below.

public class YoutubeFragment  extends YouTubeBaseActivity {


    @Override
    protected void onCreate(@Nullable Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_youtube_fragment);

        FragmentManager fm = getFragmentManager();
        String tag = YouTubePlayerFragment.class.getSimpleName();
        YouTubePlayerFragment playerFragment = (YouTubePlayerFragment) fm.findFragmentByTag(tag);
        if (playerFragment == null) {
            FragmentTransaction ft = fm.beginTransaction();
            playerFragment = YouTubePlayerFragment.newInstance();
            ft.add(android.R.id.content, playerFragment, tag);
            ft.commit();
        }

        playerFragment.initialize(MainActivity.API_KEY, new YouTubePlayer.OnInitializedListener() {
            @Override
            public void onInitializationSuccess(YouTubePlayer.Provider provider, YouTubePlayer youTubePlayer, boolean b) {
                youTubePlayer.loadVideo(MainActivity.VIDEO_ID);
            }

            @Override
            public void onInitializationFailure(YouTubePlayer.Provider provider, YouTubeInitializationResult youTubeInitializationResult) {
                Toast.makeText(YoutubeFragment.this, "Failed.", Toast.LENGTH_LONG).show();
            }
        });
    }
}

Edit activity_main.xml layout

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:id="@+id/activity_main"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:paddingBottom="@dimen/activity_vertical_margin"
    android:paddingLeft="@dimen/activity_horizontal_margin"
    android:paddingRight="@dimen/activity_horizontal_margin"
    android:paddingTop="@dimen/activity_vertical_margin"
    tools:context="com.questdot.youtubeplayerexample.MainActivity">

    <Button
        android:text="Fragment"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_alignParentBottom="true"
        android:id="@+id/btnFragment"

Edit MainActivity.java class

Modify this class, add your API key from the Google Console. And also add the video id from the youtube like https://www.youtube.com/watch?v=(xxxxxx). The xxx is video id in the youtube website.

public class MainActivity extends Activity {

    Button btnActivity;
    Button btnFragment;
    public static final String API_KEY = "AIzaSyDi97kbUT9Zek8MD495XXvz9oHrUwwPovE";
    public static final String VIDEO_ID = "Ey_hgKCCYU4";

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        btnActivity = (Button)findViewById(R.id.btnActivity);
        btnFragment = (Button)findViewById(R.id.btnFragment);

        btnActivity.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View view) {
                Intent intent = new Intent(getApplicationContext(),YoutubeActivity.class);
                startActivity(intent);
            }
        });

        btnFragment.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View view) {
                Intent intent = new Intent(getApplicationContext(),YoutubeFragment.class);
                startActivity(intent);
            }
        });


    }
}
