Completely wrong.

Integrating Firebase Services

Google has acquired a company named Firebase and is now offering many backend services under the Firebase umbrella. Most of them are free. Integrating the services is relatively simple. 1. Use B4A Sdk Manager tool to install all recommended items. 2. Register with Firebase and create a new...

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
