Firebase

[Polyterative]

I'm unable to initialize Firebase in this boilerplate.
Error is Make sure to call FirebaseApp.initializeApp(Context) first

Looks like I'm unable to call the FirebaseApp.initializeApp(Context) in the main process.
So far I tried in

• MainActivity
• Application class (myName extends Application)

I'm completely unable to use any Firebase-enabled service.

Please help
