Android Question FirebaseMessaging

[Cadenzo]

Using FirebaseMessaging with B4A 8.3 (not with B4A 8.0) I get an error with the method .SubscribeToTopic

(java.lang.NoSuchMethodError: No virtual method subscribeToTopic(Ljava/lang/StringLcom/google/android/gms/tasks/Task; in class Lcom/google/firebase/messaging/FirebaseMessaging; or its super classes (declaration of 'com.google.firebase.messaging.FirebaseMessaging' appears in /data/app/com.heikohinz.testmsg-K8oy8m6Y1lXPbzfE2jR46A==/base.apk)

Any ideas what I am doing wrong?

Make sure to replace the files in your INTERNAL Library folder (Library inside installationdir)

B4A 8.30 includes FirebaseNotifications v1.21 instead of 1.10.
I copied jar & xml from B4A 8.00 and an error was disappeared. Of course, this is not a solution, because v.1.21 "Fixes a compatibility issue with latest version of Firebase SDK"

You need to update firebase-messaging in B4A Sdk Manager.

 

[Semen Matusovskiy]

Maven is latest com.google.firebase\:firebase-messaging=17.0.0

To be sure, I deleted b4a_remote folder and reinstall all recommended.

jar from 8.00 (unlike 8.30) works fine.

Yes, after updating firebase-messaging it works
