My imports section:

#AdditionalJar: androidx.legacy:legacy-support-core-utils
#AdditionalJar: androidx.annotation:annotation
#AdditionalJar: androidx.core:core
#AdditionalJar: androidx.appcompat:appcompat
#AdditionalJar: androidx.legacy:legacy-support-v4
'lines above are for other parts of the app

#Extends: android.support.v7.app.AppCompatActivity
#AdditionalJar: com.android.support.constraint:constraint-layout
#AdditionalJar: com.android.support.constraint:constraint-layout-solver
#AdditionalJar: com.android.support:customtabs
#AdditionalJar: android.arch.lifecycle:extensions
#AdditionalJar: com.google.android.gms:play-services-auth
#AdditionalJar: com.google.firebase:firebase-auth
#AdditionalJar: firebase-ui-auth.aar
#AdditionalJar: firebase-ui-common.aar
#AdditionalJar: firebase-ui-database.aar
#AdditionalJar: firebase-ui-firestore.aar
#AdditionalJar: firebase-ui-storage.aar
#AdditionalRes: ..\res.FirebaseUI
I also tried with the new AndroidX dependencies as they told in the Github https://github.com/firebase/FirebaseUI-Android
B4X:
#AdditionalJar: android.arch.lifecycle:extensions
#AdditionalJar: androidx.browser:browser
#AdditionalJar: androidx.cardview:cardview
#AdditionalJar: androidx.constraintlayout:constraintlayout
#AdditionalJar: com.google.android.material:material
It seems like the ConstraintsLayout dependency are not compiling correctly...

Thank you in advance.

Best regards,
Alberto

Hi. I am trying to implement the FirebaseUI lib by DonManfred
the problem is that the library is 2 years old. I can´t help on this issue as i do not have a working FBUI Library as of now. I never got the newest github project working. It is now based on kotlin too.

You are using which b4A Version?
Did you try to jetifier the library?

I suggest to not use the library.

Instead use FirebaseAuth or firebaseAuthEx2 if you need to login by email and password.

Thank you for your fast reply!

I have the latest B4A version (9.5) and yes, I tried to jetify the library.

Instead use FirebaseAuth or firebaseAuthEx2 if you need to login by email and password.
Okay. I have used the FirebaseAuth but I wish to have phone authentication and email so the FirebaseUI is an awesome project for this.
I will explore other options

Best regards,
Alberto

yes, the ui lib is nice. Really nice.

In 2017 (before migrating to androidX AND kotlin) it was working fine :-(

The newest release of the FirebaseUI Github project is using internally additional libraries. One of this additional libs is causing a problem now, I don´t know exactly it´s name but i had problems providing a correct (working) resourcefolder for the UI-Library as it now needs some more styles for this additional lib. There are styles missing somhow
