Android: fcm in the library module

Question

I ran into the strange problem of integrating Firebase Cloud Messaging in a library module. I am working on a library project in which I need to process notifications coming from the FCM server from the library itself. I do not know if this is possible or not.

Sequence of steps:

• I created Project on the Firebase Console.
• Inside the project, I created an application with a package similar to my library package.
• I downloaded and placed google-services.jsonin the library module.
• I applied the dependency in the gradle library module.
• Now I have initialized my library module in the application module. I also get a log of the generated device token from FirebaseInstanceIdService.

Problem: When I try to send push from the Firebase Console, I do not receive any notifications.

Has anyone encountered such a problem and could help me?

Answer 1

So, after repeated trial and error, I managed to get notifications.

It should be noted:

• You cannot simply integrate Firebase Cloud Notifications into the library module.
• The client application module that will use this library module will have a google-services.jsonfile in its directory, and not in the library module directory.
• The gradle client application module will be below the line in it, and not in the gradle library module:

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

FCM "google_services.json". :

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

• Firebase :

  implementation 'com.google.firebase:firebase-messaging:XX.X.X'
  

• . : res/values /strings.xml

  <string name="google_app_id" translatable="false">X:XXXXXXXXXX:android:XXXXXXXXXXXXX</string>
  

• init FCM :

  public static void start(Context context){
      FirebaseOptions options = new FirebaseOptions.Builder()
              .setApplicationId("X:XXXXXXXXXX:android:XXXXXXXXXXXXX") // Required for Analytics.
              .setApiKey("XXXXXXXXXXXXXXXXXXXXXXXXXXXXXX") // Required for Auth.
              .build();
      FirebaseApp.initializeApp(context, options);        
  }
  

• ! , Application. onCreate() .

  LibName.start(getApplicationContext());
