Firebase notification on child added/modified

Question

Is it possible to generate a push notification (if the app is not in the foreground) on firebase db changes? I started coding an android app.

Answer 1

To do it in a simple way, you can use a Service, in this Service you can set a Listener on a ref in your firebase DB when the event is triggered you can create a notify and show it to the user.
