At least the needed changes in the Manifest!

Follow the instructions carefully.

Integrating Firebase Services

Thank you all
and Sorry to bother you

I worked on Firebase projects on Android Studio and had no problems
I taught firebase projects on Delphi and had no problems
I worked on visualstudio.Net projects and had no problems
But Basic for Android I stopped here
The problem is that I liked B4A speed and I am an old programmer in Visual Basic 6 code

Well it works now
After adding the following lines

CreateResourceFromFile (Macro, FirebaseAnalytics.GooglePlayBase)
CreateResourceFromFile (Macro, FirebaseAnalytics.Firebase)
CreateResourceFromFile (Macro, FirebaseAuth.FirebaseAuth)

The question is: Why didn't you include these lines in the attached project ?
Anyway thank you all
