How to display xenforo notification via mobile app as push notification


I want to create a small app for android, it will be just to show forum alerts as push notification & whenever anyone click on notification it should redirect to default browser for showing actual page of forum .

I don't want to use any 3rd party app, I want it to look like official app of our forum.

I know phonegap & ionic very well. Please someone show me a way to acheive this.
