Android Question Firebase Messaging

[Philip Prins]

When i start the Firebase Messaging service from the tutorial i get this error

firebasemessaging_service_create (java line: 212)
java.lang.IncompatibleClassChangeError: The method 'java.io.File android.support.v4.content.ContextCompat.getNoBackupFilesDir(android.content.Context)' was expected to be of type virtual but instead was found to be of type direct (declaration of 'com.google.firebase.iid.zzg' appears in /data/app/sondo.app.android-1/base.apk)

What can be the cause?

[Erel]

Try to update the Google Repository and Android Support Repository in Android SDK Manager and then clean the project (Ctrl + P).

 

[Philip Prins]

Hello Erel, I removed the support Repository and the google repository installed it again with no succes.
I installed B4A again but the problem stays,

[Erel]

I've just tested it with the latest versions of Google Repository (38) and Android Support Repository (39) and it works properly.

Make sure that the IDE points to the correct Android SDK (there might be multiple copies installed).

 

[Philip Prins]

Hello Erel, there where severall copies installed, ik works now

Tnx\
