Play YouTube video in WebView without launching new Intent

EDIT : Now you can use YouTube Android Player API to play YouTube video in app.

The API offers these benefits :

• High-quality video playback supported on Android 2.2 (Froyo) or newer
• Easy integration with your Android application (no WebView required)
• Fullscreen and orientation change support
• Integration with the Android YouTube app using a standard set of YouTube Intents
• And more ..

ORIGINAL POST

Here's the code to play YouTube videos in WebView using video url.
Video plays in appliction itself, not launching new Intent.

XML code file:

activity_video.xml

<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:orientation="vertical"
    tools:context=".VideoActivity" >

    <Button
        android:id="@+id/btnPlay"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_gravity="center_horizontal|top"
        android:layout_margin="5dp" />

    <WebView
        android:id="@+id/videoView"
        android:layout_width="fill_parent"
        android:layout_height="match_parent" />

</LinearLayout>

Java Code File:

VideoActivity.java

public class VideoActivity extends Activity {
public static final int USER_MOBILE = 0;
public static final int USER_DESKTOP = 1;

@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_video);
final WebView video = (WebView) findViewById(R.id.videoView);
Button btnPlay = (Button) findViewById(R.id.btnPlay);
btnPlay.setText("Play Video");

btnPlay.setOnClickListener(new OnClickListener() {
@Override
public void onClick(View v) {
video.getSettings().setJavaScriptEnabled(true);
video.getSettings().setPluginState(WebSettings.PluginState.ON);
video.getSettings().setUserAgent(USER_MOBILE);
video.setWebChromeClient(new WebChromeClient() {
});

//youtube video url
////http://www.youtube.com/watch?v=WM5HccvYYQg

 final String mimeType = "text/html";
final String encoding = "UTF-8";
String html = getHTML("WM5HccvYYQg");
video.loadDataWithBaseURL("", html, mimeType, encoding, "");
}
});
}


public String getHTML(String videoId) {

String html =
"<iframe class=\"youtube-player\" "
+ "style=\"border: 0; width: 100%; height: 95%;"
+ "padding:0px; margin:0px\" "
+ "id=\"ytplayer\" type=\"text/html\" "
+ "src=\"http://www.youtube.com/embed/" + videoId
+ "?fs=0\" frameborder=\"0\" " + "allowfullscreen autobuffer "
+ "controls onclick=\"this.play()\">\n" + "</iframe>\n";

/**
 * <iframe id="ytplayer" type="text/html" width="640" height="360"
 * src="https://www.youtube.com/embed/WM5HccvYYQg" frameborder="0"
 * allowfullscreen>
 **/

return html;
}

}
