@DonManfred please create a new library named FirebaseAuthEx with your changes.

Erel said:

If you can implement it without modifying FirebaseAuth then it will be better (only depending on FirebaseAuth).

I´ve updated my post above and posted the new library.

I´m not sure if this is the right solution but it works.
It is basically a copy of the original but without GoogleSignIn and with my changes. And a different FirebaseUser-Object (FirebaseAuthUser) as it provides more properties and also new methods... Maybe the name is a bit irritating now as i read it here...

Seems a bit awkward to me having two libraries for FirebaseAuth!

Click to expand...

#additionaljar: com.google.firebase:firebase-auth
#additionaljar: com.google.android.gms:play-services-auth

DonManfred said:

You need to decide for one.

If you only want to use my lib (and NOT FirebaseAuth too) then you need to ad the two dependencies from the firebaseAuth xml to the xml from my lib.
Or you add

B4X:

#additionaljar: com.google.firebase:firebase-auth
#additionaljar: com.google.android.gms:play-services-auth

to your project

Nothing works for me ever comes the code flow there!

Sub Auth_SignedIn (Usuario Como FirebaseUser)
    Log ( "SignedIn:" & User.DisplayName)
    lblName.Text = "Hola" y User.DisplayName
End Sub

Sub Auth_SignedIn (user As FirebaseUser)
    Log ( "SignedIn:" & User.DisplayName)
    lblName.Text = "Hola" y User.DisplayName
End Sub

DonManfred said:

the sub signature is definetively wrong

B4X:

Sub Auth_SignedIn (Usuario Como FirebaseUser)
    Log ( "SignedIn:" & User.DisplayName)
    lblName.Text = "Hola" y User.DisplayName
End Sub

I´m sure you´ll get an error in the ide when compiling.

It must be

B4X:

Sub Auth_SignedIn (user As FirebaseUser)
    Log ( "SignedIn:" & User.DisplayName)
    lblName.Text = "Hola" y User.DisplayName
End Sub

This library requires B4A v6+.

It allows the users to sign in to your app with their Google account (more identity providers will be added in the future).

Like all Firebase services it is quite simple to integrate this service in your app.

1. Follow this tutorial and make sure to add the Firebase Auth manifest snippet: https://www.b4x.com/android/forum/threads/integrating-firebase-services.67692/

2. This service requires that the signing key SHA1 signature is set in the Firebase project settings:

You can find this value under Tools - Private Sign Key, in the signature field:

Initialize the FirebaseAuth object and call SignInWithGoogle to sign in. Note that the user will be signed in automatically when the program restarts.

B4X:

Sub Process_Globals
   Private auth As FirebaseAuth
End Sub

Sub Globals
   Private lblName As Label
End Sub

Sub Activity_Create(FirstTime As Boolean)
   If FirstTime Then
     auth.Initialize("auth")
   End If
   Activity.LoadLayout("1")
   If auth.CurrentUser.IsInitialized Then Auth_SignedIn(auth.CurrentUser)
End Sub

Sub btnSignIn_Click
   auth.SignInWithGoogle
End Sub

Sub btnSignOut_Click
   auth.SignOutFromGoogle
   lblName.Text = "Goodbye!"
End Sub

Sub Auth_SignedIn (User As FirebaseUser)
   Log("SignedIn: " & User.DisplayName)
   lblName.Text = "Hello: " & User.DisplayName
End Sub

- Combine Google and Facebook: https://www.b4x.com/android/forum/t...seauth-to-support-facebook.67954/#post-430482
- Server verification of signed in users: https://www.b4x.com/android/forum/t...end-authentication-for-signed-in-users.68672/

I put a user and nothing happens.
What can it be?
I have Google Sign-In enabled in Firebase
