How to use two apps in one Firebase project for push notifications

Question

I have created one project(TravellerProject) in Firebase developer console... i've added an Android App(UserApp) and i've taken Server key and i used that server key for push notification in to my App Admin site... now i have a new App(DriverApp) related to first App(UserApp)... both are same domain so i didn't created new Project, instead i added one more App in the same project(TravellerProject) with different SHA-1 key... and i was trying to use push notifications for new App(DriverApp). can i use same Server Key for both or i've to create new Server key...?

Answer 1

yes, Server Key is working... in my case problem with com.google.firebase:firebase-core version... previously i am using com.google.firebase:firebase-core:9.0.0 so refresh token was not generating... now i've changed to com.google.firebase:firebase-core:9.0.2... and now it's working... Thank you
