android: fcm in library module

Question

I am facing a weird issue integrating Firebase Cloud Messaging in a library module. I am working on a library project in which I need to handle notifications right coming from the FCM Server from the library itself. I am not aware if it is possible or not.

Steps I followed:

• I created Project on Firebase Console.
• Inside the project, I created app with package same as my library package.
• I downloaded and put google-services.json in library module.
• I have applied the dependency in gradle of library module.
• Now, I have initialized my library module in app module. I am also getting log of generated device token from FirebaseInstanceIdService.

Problem: When I try to send push from Firebase Console, I am not receiving any Notification.

Have anyone faced such issue and could help me with this ?

Answer 1

So, after running a lot through trial and error method, I succeeded in getting Notifications.

Things to be noted:

• You cannot just integrate Firebase Cloud Notifications in library module.
• Client app module who will be using this library module will have google-services.json file in his directory and not in library module directory.
• Client app module gradle will be having below line in it and not in library module gradle:

apply plugin: 'com.google.gms.google-services'

So, once I made those two changes, I was able to get Notifications.
