Actually, the same lines as in your examples work:
classpath ‘com.android.tools.build:gradle:3.0.1’
classpath ‘com.google.gms:google-services:3.1.2’
While classpath ‘com.google.gms:google-services:3.0.1’ generated “not found” errors when syncing the gradle.
So far so good. The app generates the FCM token and doesn’t crash. However when I use this token in the FB console, the push notification is not delivered. It fails.
So there is something else I am missing. The build with the simulator works fine. Something about google-services.json? It should be in the app directory now, right?
To sum it up, In Native Android I implement FCM in Java and plugin.notifications.v2.jar helps just to call FCM from .lua files, right? build.settings is ignored in this case, I guess.
it’s your responsibility to integrate them into your Android Studio project. Each Android plugin may have additional settings and configuration that you need to complete before you can use it.
