Integrating youtube to fragment

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);
