Play youtube video in full screen in default device youtube player by passing youtube video id

Hello friends, If you want to play youtube video in full screen  in default  youtube player from your device by passing youtube video id , use following code. I hope it will work for you.

Button watch=(Button)findViewById(R.id.btn_watchnow);

watch.setOnClickListener(new OnClickListener()
 {
@Override
public void onClick(View v)
{
String id="IqZf2pj4oj8";   //Youtube video id
    Intent i = new Intent(Intent.ACTION_VIEW, Uri.parse("vnd.youtube:" +id));
    startActivity(i);

}
});

Try it. It works fine for me. Again in order to give option to open in browser, just use

Uri.parse("ytv://"+id)
