Configure a Connected App For FCM (Android) | Mobile SDK Development Guide

If you have an existing Firebase project associated with your app, open the existing project. If not, create a project for your app in the Google Firebase Console.

If you previously set up notifications for your Android app, make sure that you proceed with the next steps using the existing Firebase project associated with your app. To avoid any disruption in your app’s notifications, confirm that the sender ID in the Firebase project matches your app’s existing sender ID.
