Hello,

I'm having a problem with B4A V8 and SDK 26 with the new implementation of Firebase... I have an app that is running fine in Android 5.X+ but I'm getting the follow error with 4.X:

java.lang.IllegalStateException: Default FirebaseApp is not initialized in this process com.comten.nexphone. Make sure to call FirebaseApp.initializeApp(Context) first.

The same app was running fine in 4.X AND 5.X with B4A 7.3 and SDK 21...

Any suggestion?

Are you using the latest version: Firebase Notifications & Firebase Auth Issues
?

It sounds like a configuration issue. The same error was discussed and solved here: https://www.b4x.com/android/forum/threads/firebasenotifications-manifest-error.93947/#post-594443

Hello @Erel , thanks for fast answering. Reviewing the Manifest, I found some legacy code from old firebase notifications configuration (related to B4A 7.3). This code didn't impact in Android 5+ versions, but was crashing 4.X... once deleted the legacy lines (maintaining only the B4A V8 macro created), the app worked fine again even in version 4.X ...

Thanks again ! :)

@Marcos Alves What was the legacy code that you found?

I have the same issues with old users under kitkat and lollypop versions of Android. Could you please share your manifiest file?
