Load specified YouTube playlist

To load specified YouTube playlist in YouTube Android Player, simple call cuePlaylist(PlayList_ID) method of YouTubePlayer object, instead of cueVideo(VIDEO_ID) method.

Modify onInitializationSuccess(Provider provider, YouTubePlayer player, boolean wasRestored) method in MainActivity.java from last exercise "Example to use YouTubePlayerFragment of YouTube Android Player API".

 public static final String PlayList_ID = "PLP7qPet500dfglA7FFTxBmB_snxCaMHDJ";

 @Override
 public void onInitializationSuccess(Provider provider, YouTubePlayer player,
   boolean wasRestored) {
  
  youTubePlayer = player;
  
  Toast.makeText(getApplicationContext(), 
    "YouTubePlayer.onInitializationSuccess()", 
    Toast.LENGTH_LONG).show();
  
  youTubePlayer.setPlayerStateChangeListener(myPlayerStateChangeListener);
  youTubePlayer.setPlaybackEventListener(myPlaybackEventListener);
  
  if (!wasRestored) {
   //player.cueVideo(VIDEO_ID);
   player.cuePlaylist(PlayList_ID);
  }

The tutorial: YouTube Android Player API step-by-step

Force YouTube Android Player to run in full screen mode

TO force YouTube Android Player to run in full screen mode, simple call setFullscreen(true) method of the YouTubePlayer object.

Modify from last exercise "Handle player state changes and playback events, by implementing PlayerStateChangeListener and PlaybackEventListener.", to add a Button in layout, to force running in Full Screen mode.

The Tutorial: YouTube Android Player API step-by-step

Handle initialization error YouTube API Service

Refer to the exercises of "Simple example using YouTube Android Player API" and "YouTubeThumbnailView example", onInitializationFailure() methods will be called with YouTubeInitializationResult passed if fail in initialization.

If the error is is user-recoverable (isUserRecoverableError() == true), we can proceed by calling getErrorDialog(Activity, int), and then show this dialog to enable users to recover from this error.

Modify MainActivity.java from last exercise "YouTubeThumbnailView example of YouTube Android Player API" to handle onInitializationFailure() for YouTubePlayer and YouTubeThumbnailView.

The Tutorial: YouTube Android Player API step-by-step

Simple example using YouTube Android Player API

Before create app using YouTube Android Player API, you have to "Download and import YouTube Android Player API" and "Register your app using YouTube Android Player API and obtain API Key".

Modify layout xml to add view of <com.google.android.youtube.player.YouTubePlayerView>.

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    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=".MainActivity" >

    <TextView
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="http://android-er.blogspot.com/"
        android:textStyle="bold"
        android:layout_gravity="center_horizontal"
        android:autoLink="web" />
    
    <com.google.android.youtube.player.YouTubePlayerView
        android:id="@+id/youtubeplayerview"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"/>

</LinearLayout>

Modify MainActivity.java, extends YouTubeBaseActivity implements YouTubePlayer.OnInitializedListener.

package com.example.androidyoutubeapiplayer;

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

import android.os.Bundle;
import android.widget.Toast;

public class MainActivity extends YouTubeBaseActivity implements
YouTubePlayer.OnInitializedListener{
 
 public static final String API_KEY = "AIzaSyCe6tORd9Ch4lx-9Ku5SQ476uS9OtZYsWA";
 public static final String VIDEO_ID = "o7VVHhK9zf0";

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        
        YouTubePlayerView youTubePlayerView = (YouTubePlayerView)findViewById(R.id.youtubeplayerview);
        youTubePlayerView.initialize(API_KEY, this);
    }

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

 @Override
 public void onInitializationSuccess(Provider provider, YouTubePlayer player,
   boolean wasRestored) {
  if (!wasRestored) {
        player.cueVideo(VIDEO_ID);
      }
 }

}

Where API_KEY is the key obtained in the step of "Register your app using YouTube Android Player API and obtain API Key", VIDEO_ID is the ID of the video to play.

Permission of "android.permission.INTERNET" is needed in AndroidManifest.xml.

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
    package="com.example.androidyoutubeapiplayer"
    android:versionCode="1"
    android:versionName="1.0" >

    <uses-sdk
        android:minSdkVersion="8"
        android:targetSdkVersion="17" />
    <uses-permission android:name="android.permission.INTERNET"/>

    <application
        android:allowBackup="true"
        android:icon="@drawable/ic_launcher"
        android:label="@string/app_name"
        android:theme="@style/AppTheme" >
        <activity
            android:name="com.example.androidyoutubeapiplayer.MainActivity"
            android:label="@string/app_name" >
            <intent-filter>
                <action android:name="android.intent.action.MAIN" />
                <category android:name="android.intent.category.LAUNCHER" />
            </intent-filter>
        </activity>
    </application>

</manifest>

YouTube Android Player API step-by-step

The YouTube Android Player API enables you to incorporate video playback functionality into your Android applications. The API defines methods for loading and playing YouTube videos (and playlists) and for customizing and controlling the video playback experience.

Using the API, you can load or cue videos into a player view embedded in your application's UI. You can then control playback programmatically. For example, you can play, pause, or seek to a specific point in the currently loaded video.

You can also register event listeners to get callbacks for certain events, such as the player loading a video or the player state changing. Finally, the API has helper functionality to support orientation changes as well as transitions to fullscreen playback.
