Android Question Firebase authentication problem

[Matrix]

Hello,

I have a Firebase authentication problem - but I do not know what is the problem
I followed the instructions

1. Register with Firebase and create a new project
2. Add Android app under project setting
3. the package name matches my app's package name -> b4a.firebase
4. Create a private Key with B4A / Tools/Private-Key and copy the SHA1 Key
5. I use thecreate SHA1 Key for Fingerprint to register the APP at Firebase
6. Download the google-services.json in the b4a project root

after programstart
-> auth.CurrentUser.IsInitialized get false return !?

Where is the problem now?
I hope someone has an idea
Thank you

It is expected not to be initialized. Have you clicked on the sign in button? What happens?

Hello Erel,

I can start the program without any errors
I click the sign in button and than I get the message from msgbox "connection error"

in the debug mode step by step :

If auth.CurrentUser.IsInitialized Then
Auth_SignedIn(auth.CurrentUser)
Else
Msgbox("connection error " ,"Firebase")
End If

I think I have a configuration problem between b4a and google??
but woh?

packed name is the same : b4a.firebase
SHA1 Key is copied to Firebase project
google-services.json is copied from firebase to b4a root

I have to adjust something else under firebase?
is there any way to find out more about the mistake, what is wrong. via a special debug function

Thank you
Timo

I click the sign in button and than I get the message from msgbox "connection error"

The code that should be executed is:

Sub btnSignIn_Click
auth.SignInWithGoogle
End Sub

Sorry, I have to correct myself!
I just started the project again

the problem occurs at the start before clicking sign in button

if start the project and I debug the code step by step

here is my problem => auth.CurrentUser.IsInitialized


Sub Activity_Create(FirstTime As Boolean)

If FirstTime Then
auth.Initialize("auth")
End If

Activity.LoadLayout("layout1")

If auth.CurrentUser.IsInitialized Then
Auth_SignedIn(auth.CurrentUser)
Else
Msgbox("conecting error " ,"Firebase")
End If

End Sub



again sorry for my mistake!!

Please use [code]code here...[/code] tags when posting code.

See my answer in post #2.

OK
if the problem occurs at Sub Activity_Create
so I think it is an initialization error ??

or it may also be an installation problem of the development environment?

Sub Activity_Create(FirstTime As Boolean)

If FirstTime Then
auth.Initialize("auth")
End If

Activity.LoadLayout("layout1")

If auth.CurrentUser.IsInitialized Then
Auth_SignedIn(auth.CurrentUser)
Else
Msgbox("conecting error " ,"Firebase")
End If

End Sub

Which problem?

Quoting my self:
It is expected not to be initialized. Have you clicked on the sign in button? What happens?

sometimes I'm blind - since I had problems with the configuration all the time, I did not test any further back ... I saw only the mistake in the beginning, which is actually no one ... super

If I cklick so open a google Login or user selection window. I can choose a user and then I get the User infos. - so far ok! thank you

question:
you can specify a user so that the selection window does not appear?


my next question
for access to the Firebase database , I need the TokenID
this TokenID can I read with auth.GetuserTokenid(User,False)
- is this correct ?


What is the best way/function to access the database?
can I use download2 from library OkHttpUtils2
for example

Dim j As HttpJob
    j.Initialize("", Me)
    'full list of features available: person.addresses,person.age_ranges,person.biographies,person.birthdays,person.bragging_rights,person.cover_photos,person.email_addresses,person.events,person.genders,person.im_clients,person.interests,person.locales,person.memberships,person.metadata,person.names,person.nicknames,person.occupations,person.organizations,person.phone_numbers,person.photos,person.relations,person.relationship_interests,person.relationship_statuses,person.residences,person.skills,person.taglines,person.urls
    j.Download2("https://people.googleapis.com/v1/people/me", _
         Array As String("access_token", TokenID, "requestMask.includeField", "person.email_addresses,person.birthdays,person.names"))
    Wait For (j) JobDone(j As HttpJob)
    If j.Success Then
        ParsePersonData(j.GetString)
    Else
        oauth2.ResetToken
        ToastMessageShow("Online data not available.", True)
    End If
    j.Release

or is there still a way?


Thank you
Timo
