My Activity extends another activity and consists of navigation drawer where each item opens a new fragment.I want to integrate Youtube to one of the fragment..Previously i used YouTubePlayerView to integrate Youtube to activity but here it is required in fragment.I searched on net and found YouTubePlayerFragment to integrate youtube to fragment. But when i searched in tutorials I found that even by using YouTubePlayerFragment we are extending YouTubeBaseActivity .These are the examples.. http://android-coding.blogspot.in/2013/04/example-to-use-youtubeplayerfragment-of.html http://android-er.blogspot.in/2013/06/example-to-use-youtubeplayerfragment-of.html

I failed to understand how to use YouTubePlayerFragment such that my class extends Fragment rather than YouTubeBaseActivity which is required in my project..As u can see below my class extends another activity and consists of navigation drawer in which fifth option opens YouTube Fragment.I want to play Youtube video inside this fragment..I am giving brief layout how my classes are-

public class LandingActivity extends BaseGActivity {
.
.

        Bundle args = new Bundle();

        switch (position) {

layout

 <?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent">
    <fragment
        android:name="com.google.android.youtube.player.YouTubePlayerSupportFragment"
        android:id="@+id/youtube_fragment"
        android:layout_width="match_parent"

</LinearLayout>

Error-

Error:(64, 101) error: <anonymous com.pc.gi.ui.fragment.YoutubeFragment$1> is not abstract and does not override abstract method onInitializationFailure(Provider,YouTubeInitializationResult) in OnInitializedListener

First extend your Activity as normal

 class YourActivity extends Activity...

in Layout file put the below lines

<fragment
  android:name="com.google.android.youtube.player.YouTubePlayerSupportFragment"
  android:id="@+id/youtube_fragment"
  android:layout_width="match_parent"
  android:layout_height="wrap_content"/>

Then in your Activity you can create its instance using below line in your onCreareView method of your Fragment.

YouTubePlayerSupportFragment youTubePlayerFragment = (YouTubePlayerSupportFragment) getActivity().getSupportFragmentManager()
                    .findFragmentById(R.id.youtube_fragment);

or you can declare a FrameLayout in your xml and then initiate the YouTubeSupportFragment using below lines

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent" >

    <FrameLayout
        android:id="@+id/youtube_fragment"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:layout_centerHorizontal="true"
        android:visibility="visible" />

</RelativeLayout>

Code in your onCreateView

 YouTubePlayerSupportFragment youTubePlayerFragment = YouTubePlayerSupportFragment.newInstance();

    youTubePlayerFragment.initialize("DEVELOPER_KEY", new OnInitializedListener() {

        @Override
        public void onInitializationSuccess(YouTubePlayer.Provider provider, YouTubePlayer player, boolean wasRestored) {

            if (!wasRestored) {
                YPlayer = player;
                YPlayer.setFullscreen(true);
                YPlayer.loadVideo("2zNSgSzhBfM");
                YPlayer.play();
            }

        }

        @Override
        public void onInitializationFailure(Provider arg0, YouTubeInitializationResult arg1) {
            // TODO Auto-generated method stub

        }
    });
    FragmentTransaction transaction = getChildFragmentManager().beginTransaction();
    transaction.add(R.id.youtube_fragment, youTubePlayerFragment).commit();

The key thing here is to use YouTubePlayerSupportFragment instead of YouTubePlayerFragment.

Hope this helps.

Here is your Fragment

import android.app.Activity;
import android.os.Bundle;
import android.support.v4.app.Fragment;
import android.support.v4.app.FragmentActivity;
import android.support.v4.app.FragmentTransaction;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;

import com.google.android.youtube.player.YouTubeInitializationResult;
import com.google.android.youtube.player.YouTubePlayer;
import com.google.android.youtube.player.YouTubePlayer.OnInitializedListener;
import com.google.android.youtube.player.YouTubePlayer.Provider;
import com.google.android.youtube.player.YouTubePlayerSupportFragment;
import com.ismart.omanapp.R;

public class YoutubeFragment extends Fragment {
    private FragmentActivity myContext;

    private YouTubePlayer YPlayer;
    private static final String YoutubeDeveloperKey = "xyz";
    private static final int RECOVERY_DIALOG_REQUEST = 1;

    @Override
    public void onAttach(Activity activity) {

        if (activity instanceof FragmentActivity) {
            myContext = (FragmentActivity) activity;
        }

        super.onAttach(activity);
    }

    @Override
    public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {

        View rootView = inflater.inflate(R.layout.activity_you_tube_api, container, false);

        YouTubePlayerSupportFragment youTubePlayerFragment = YouTubePlayerSupportFragment.newInstance();
        FragmentTransaction transaction = getChildFragmentManager().beginTransaction();
        transaction.add(R.id.youtube_fragment, youTubePlayerFragment).commit();

        youTubePlayerFragment.initialize("DEVELOPER_KEY", new OnInitializedListener() {

            @Override
            public void onInitializationSuccess(Provider arg0, YouTubePlayer youTubePlayer, boolean b) {
                if (!b) {
                    YPlayer = youTubePlayer;
                    YPlayer.setFullscreen(true);
                    YPlayer.loadVideo("2zNSgSzhBfM");
                    YPlayer.play();
                }
            }

            @Override
            public void onInitializationFailure(Provider arg0, YouTubeInitializationResult arg1) {
                // TODO Auto-generated method stub

            }
        });

    }
}

To implement youtube player using fragment follow these 3 steps below:-

  1. In the activity XML file add these:

     <fragment
             android:name="com.google.android.youtube.player.YouTubePlayerFragment"
             android:id="@+id/youtube_fragment"
             android:layout_width="match_parent"
             android:layout_height="wrap_content"/>
    
  2. In activity java file create a new OnInitialize listener

    YouTubePlayer.OnInitializedListener onInitializedListener = new 
    YouTubePlayer.OnInitializedListener() {
         @Override
         public void onInitializationSuccess(YouTubePlayer.Provider provider, YouTubePlayer youTubePlayer, boolean b) {
    
             youTubePlayer.loadVideo("Your_video_id");
    
    
    
         }
    
         @Override
         public void onInitializationFailure(YouTubePlayer.Provider provider, YouTubeInitializationResult youTubeInitializationResult) {
    
         }
     };
    
  3. After initializing the listener get the fragment reference and initialize the player.

    YouTubePlayerFragment youTubePlayerFragment = (YouTubePlayerFragment) getFragmentManager().findFragmentById(R.id.youtube_fragment);
    youTubePlayerFragment.initialize("You_Developer_Api_Key", onInitializedListener);
