Youtube Player for playing videos

Now you have YouTube player ,so no need to use Web view or any other player.
add below code in your main.xml file where you want YouTube player.

   <com.google.android.youtube.player.YouTubePlayerView
                android:id="@+id/youtube_view"
                android:layout_width="fill_parent"
                android:layout_height="fill_parent" />

Now ,Create one class name DeveloperKey

public class DeveloperKey {

// This is developer key you can get it from creating project in Google API Console.
public static final String DEVELOPER_KEY = "This is your developer key";
}

Create second class name YouTubeFailureRecoveryActivity

public abstract class YouTubeFailureRecoveryActivity extends YouTubeBaseActivity implements
    YouTubePlayer.OnInitializedListener {

private static final int RECOVERY_DIALOG_REQUEST = 1;

@Override
public void onInitializationFailure(YouTubePlayer.Provider provider,
      YouTubeInitializationResult errorReason) {
    if (errorReason.isUserRecoverableError()) {
      errorReason.getErrorDialog(this, RECOVERY_DIALOG_REQUEST).show();
    } else {
      String errorMessage = String.format(getString(R.string.error_player), errorReason.toString());
      Toast.makeText(this, errorMessage, Toast.LENGTH_LONG).show();
    }
}

@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(DeveloperKey.DEVELOPER_KEY, this);
    }
}

protected abstract YouTubePlayer.Provider getYouTubePlayerProvider();

}

This is your main activity

public class MainActivity extends YouTubeFailureRecoveryActivity {

       YouTubePlayerView youTubeView;
       private YouTubePlayer youTubePlayer;

    @SuppressLint("NewApi")
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        // TODO Auto-generated method stub
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);

        youTubeView = (YouTubePlayerView)findViewById(R.id.youtube_view);
        youTubeView.initialize(DeveloperKey.DEVELOPER_KEY, this);
    }
    @Override
    public void onInitializationSuccess(YouTubePlayer.Provider provider, YouTubePlayer player,
          boolean wasRestored) {
            if (!wasRestored) {
            // wKJ9KzGQq0w is your video id
                  player.cueVideo("wKJ9KzGQq0w");
                }
    }
    @Override
    protected YouTubePlayer.Provider getYouTubePlayerProvider() {
        return (YouTubePlayerView) findViewById(R.id.youtube_view);
    }
}

Don't forget to give Internet permission in your manifest file.
also you need to get YouTubeAndroidPlayerApi.jar

==> In your Manifest.xml file define some permissions and code for Map V2 as below.

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
    package="com.example.mapv2demo"
    android:versionCode="1"
    android:versionName="1.0" >

    <uses-sdk
        android:minSdkVersion="8"
        android:targetSdkVersion="17" />

    <uses-feature
        android:glEsVersion="0x00020000"
        android:required="true" />
    <uses-permission android:name="com.example.mapv2demo.permission.MAPS_RECEIVE" />
     <uses-permission android:name="android.permission.INTERNET" />
    <uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" />
    <uses-permission android:name="android.permission.CAMERA" />

        android:icon="@drawable/ic_launcher"
        android:label="@string/app_name"
        android:theme="@style/AppTheme" >
        <activity
            android:name="com.example.mapv2demo.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>
         <meta-data
            android:name="com.google.android.maps.v2.API_KEY"
            android:value="Your API Key" />
    </application>

</manifest>

==> And Now run this application , it Display Google Map V2.
