Get Launch Intent

I'm trying to figure out how to do the following in titanium.

Intent intent = getPackageManager().getLaunchIntentForPackage("com.other.app");
if (intent == null) {
    openURL( "http://play.google.com/store/apps/details?id=com.other.app" );
} else {
    startActivity(intent);
}

I was hoping to avoid manually configuring the intent with an action and category in case the other app is updated and something changes. I just thought it would be best to automatically get the launch intent.
