My guess is that you've implemented FirebaseAdMob without the required app id. This is of course just a wild guess.
i use FireBaseNotification! A few days ago, when I ran it, it ran without any problems.
I have encountered the problem that when I do not work on a project for a while, it has this kind of failure after a while.
I checked that this happens when I use Firebase.
When I delete the following lines, my application opens but gives an error for FireBase.
CreateResourceFromFile(Macro, FirebaseAnalytics.GooglePlayBase)
CreateResourceFromFile(Macro, FirebaseAnalytics.Firebase)
CreateResourceFromFile(Macro, FirebaseNotifications.FirebaseNotifications)
what should i do? i want to use Firebase notification!
and when i remove these lines. b4a will gives an error like
java.lang.IllegalStateException: Default FirebaseApp is not initialized in this process com.zimath.programingnter. Make sure to call FirebaseApp.initializeApp(Context) first.
