Create two java classes :

2. MainActivity.java

After you creating all layout and java classes, now modify these layout and java classes one by one. 

Modify your activity_main.xml, paste the following code :

	<?xml version="1.0" encoding="utf-8"?>
	<LinearLayout 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"
	android:orientation="vertical"
	tools:context="com.putuguna.youtubeplayeronapps.MainActivity">
	<TextView
	android:textStyle="bold"
	android:gravity="center"
	android:layout_width="wrap_content"
	android:layout_height="wrap_content"
	android:text="Subscribe : url/channel/UCt7a2o143ngbccCuV0ZMrpQ"
	android:layout_marginBottom="10dp"/>
	<com.google.android.youtube.player.YouTubePlayerView

	android:layout_width="match_parent"
	android:layout_height="match_parent"></com.google.android.youtube.player.YouTubePlayerView>

Modify your Constant.java, define your YOUTUBE API KEY and the YOUTUBE VIDEO ID here. You can find out the YOUTUBE VIDEO ID on the URL.

Example the URL is : https://www.youtube.com/watch?v=WhRaCA9bC9k. WhRaCA9bC9k is the video ID.

take a look at the following code :

	package com.putuguna.youtubeplayeronapps;
	/**
	* Created by putuguna on 09/12/16.
	*/
	public class Constant {
	public static final String YOUTUBE_API_KEY = "AIzaSyCdPy5ZUkJ1arINjSEHmGx0SgrjlctOTwU";
	public static final String YOUTUBE_ID = "WhRaCA9bC9k";
	}

Last, modify your MainActivity.java, MainActivity.java has to extends YoutubeBaseActivity. Paste the following code :

	package com.putuguna.youtubeplayeronapps;
	import android.content.ContentResolver;
	import android.content.ContentValues;
	import android.content.Intent;
	import android.net.Uri;
	import android.os.Bundle;
	import android.provider.MediaStore;
	import android.provider.Settings;
	import android.support.v7.app.AppCompatActivity;
	import android.view.Menu;
	import android.view.MenuInflater;
	import android.view.MenuItem;
	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 MainActivity extends YouTubeBaseActivity implements YouTubePlayer.OnInitializedListener {
	private static final int REQUEST_NUMBER = 999;
	private YouTubePlayerView youTubePlayerView;
	@Override
	protected void onCreate(Bundle savedInstanceState) {
	super.onCreate(savedInstanceState);
	setContentView(R.layout.activity_main);
	youTubePlayerView = (YouTubePlayerView) findViewById(R.id.youtube_player);
	//set the api key here
	youTubePlayerView.initialize(Constant.YOUTUBE_API_KEY,this);
	}
	@Override
	public void onInitializationSuccess(YouTubePlayer.Provider provider, YouTubePlayer youTubePlayer, boolean b) {
	if(!b){
	youTubePlayer.cueVideo(Constant.YOUTUBE_ID);
	/**
	* there are 2 method you can user here :
	* .cueVideo(), for didn't play automatically
	* .loadVideo(), for do play automatically
	*
	* if you are using play automatically, it better if you hide the video controllers
	* do like below :
	* youTubePlayer.setPlayerStyle(YouTubePlayer.PlayerStyle.CHROMELESS);//hide the players controllers
	*/
	}
	}
	@Override
	public void onInitializationFailure(YouTubePlayer.Provider provider, YouTubeInitializationResult youTubeInitializationResult) {
	if(youTubeInitializationResult.isUserRecoverableError()){
	youTubeInitializationResult.getErrorDialog(this, REQUEST_NUMBER).show();
	}else{
	String errorMessage = String.format(
	"There was an error initializing the YouTubePlayer (%1$s)", youTubeInitializationResult.toString()
	);
	Toast.makeText(this, errorMessage, Toast.LENGTH_SHORT).show();
	}
	}
	@Override
	protected void onActivityResult(int requestCode, int resultCode, Intent data) {
	//super.onActivityResult(requestCode, resultCode, data);
	if(requestCode==REQUEST_NUMBER){
	youTubePlayerView.initialize(Constant.YOUTUBE_API_KEY,this);
