Example to use YouTubePlayerFragment of YouTube Android Player API

Before start coding using YouTube Android Player API, read the post to prepare your development tools.

Example to use YouTubePlayerFragment

To use YouTubePlayerFragment in your app, android:minSdkVersion have to be set "11" or higher.

Modify activity_main.xml to include <fragment> of "com.google.android.youtube.player.YouTubePlayerFragment" in your layout.

<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="@string/hello_world" />
    <fragment
      android:name="com.google.android.youtube.player.YouTubePlayerFragment"
      android:id="@+id/youtubeplayerfragment"
      android:layout_width="match_parent"
      android:layout_height="wrap_content"/>

</LinearLayout>

Modify MainActivity.java, to extend YouTubeBaseActivity and implements YouTubePlayer.OnInitializedListener. Replace your the String DEVELOPER_KEY with your own API Key obtain in the post "Preparation for development with YouTube Android Player API".

package com.example.androidyoutubeplayerfragment;

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

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

public class MainActivity extends YouTubeBaseActivity 
 implements YouTubePlayer.OnInitializedListener{
 
 public static final String DEVELOPER_KEY = "replace your own API Key here";
 private static final int RECOVERY_DIALOG_REQUEST = 1;
 private static final String VIDEO_ID = "fhWaJi1Hsfo";
 
 YouTubePlayerFragment myYouTubePlayerFragment;

 @Override
 protected void onCreate(Bundle savedInstanceState) {
  super.onCreate(savedInstanceState);
  setContentView(R.layout.activity_main);
  myYouTubePlayerFragment = (YouTubePlayerFragment)getFragmentManager()
    .findFragmentById(R.id.youtubeplayerfragment);
  myYouTubePlayerFragment.initialize(DEVELOPER_KEY, this);
 }
 
 @Override
 public void onInitializationFailure(YouTubePlayer.Provider provider,
   YouTubeInitializationResult errorReason) {
  if (errorReason.isUserRecoverableError()) {
   errorReason.getErrorDialog(this, RECOVERY_DIALOG_REQUEST).show(); 
  } else {
   String errorMessage = String.format(
     "There was an error initializing the YouTubePlayer (%1$s)", 
     errorReason.toString());
   Toast.makeText(this, errorMessage, Toast.LENGTH_LONG).show(); 
  } 
 }

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

 protected YouTubePlayer.Provider getYouTubePlayerProvider() {
  return (YouTubePlayerView)findViewById(R.id.youtubeplayerfragment); 
 }

}
