 // default youtube app
 Intent i = new Intent(Intent.ACTION_VIEW, Uri.parse("vnd.youtube:" + videoID));
 List list = getPackageManager().queryIntentActivities(i, PackageManager.MATCH_DEFAULT_ONLY);
 if (list.size() == 0) {
  // default youtube app not present or doesn't conform to the standard we know
  // use our own activity
  i = new Intent(getApplicationContext(), YouTube.class);
  i.putExtra("VIDEO_ID", videoID);
 }
 startActivity(i);
