I have spent a few hours (if not days) reading and trying to get this thing working. I want to be able to authenticate users (and let them register) on my app. I've used, among other things, the Firebase console provided in Android Studio to set up the application (so it's registered and linked, and my google-services.json is indeed in the app folder).
The resources I've been following (they somehow ALL provide different code snippets, which is super confusing):
- Google's YouTube Firebase PlayList
- FirebaseUI-Android repo on GitHub
- FirebaseUI-Android's explanation for integration
- Firebase's quickstart-android repo on GitHub
- Some Firebase Documentation I'm not sure how to use or if it's even relevant
- I've also implemented a "Login Activity" as proposed as a Template by Android Studio itself.
Screenshot of app's "Sign-in method" settings in the Firebase Console (so yes, I want to integrate those 3 options): 
My
Logcat when I test the "Google Sign In Button", after selecting my profile, in my one-and-only half-working Activity (the one that was mostly based off he "quickstart" ressource):

My build.gradle:
dependencies {
//...
api 'com.google.firebase:firebase-auth:16.0.2'
implementation 'com.firebaseui:firebase-ui-auth:4.1.0'
implementation 'com.google.firebase:firebase-core:16.0.1'
implementation 'com.google.android.gms:play-services-auth:15.0.1'
//...
}
apply plugin: 'com.google.gms.google-services'
Part of the other build.gradle:
buildscript {
repositories {
google()
jcenter()
}
dependencies {
classpath 'com.android.tools.build:gradle:3.1.3'
classpath 'com.google.gms:google-services:4.0.1'
}
}
allprojects {
repositories {
google()
jcenter()
}
}
NOTE: upgrading to classpath 'com.google.gms:google-services:4.0.2' gives me the following Logcat after pressing the "Google Sign In Button" and selecting my account:

This is kind of frustrating. I hope you guys can help. I can provide more code if needed... :/
I'm surprised there is no easy way to just copy-paste a bunch of code and get it running. Even setting up the Activity's UI is quite the process. I can't seem to find the specific pieces that I want from the, for example, "FirebaseUI-Android" repo.
