Firebase Cloud Messaging fails authentication for SDK 31+ on Android 12+

Question

I set up FCM for my app. And it works perfectly for devices run under Android 11 and less. But for devices under Android 12 and greater I can't receive token by using

FirebaseMessaging.getInstance().token.addOnCompleteListener {
            ...
        } 

I receive an error: java.io.IOException: java.util.concurrent.ExecutionException: java.io.IOException: AUTHENTICATION_FAILED instead of token

    override fun onMessageReceived(message: RemoteMessage) {
        super.onMessageReceived(message)

        println("->> new message: ${message.notification?.title} - ${message.notification?.body}")

Does anybody have some suggestions?

Data: App targeted: SDK33 Run under : SDK31 FCM version : 23.0.6

Answer 1

The issue was with an emulator, FCM doesn't provide a token for devices under SDK31+ without Google play services. To solve the issue and get a token you have to use an emulator or device with installed Google play services, Google APIs are not enough.
