Please help, I spent all the morning from one problem to another...

@hiddeneyes02 what version of Android Studio are you using? Could you try adding the following lines to your gradle.properties file and seeing if anything changes?

android.enableR8 = false
android.enableD8 = false

[dzboot02]

I am using Android Studio 3.1, lastest

This is what I get with that:

The option 'android.enableD8' is deprecated and should not be used anymore.
Use 'android.enableD8=true' to remove this warning.
It will be removed in AGP version 3.3.

The same original error if I remove android.enableD8 = false or set it to true

I have to revert to firebase ui auth 3.0.0 to make things work right now.

[samtstern]

@hiddeneyes02 what about FirebaseUI 3.2.2?

[dzboot02]

Could not resolve all dependencies for configuration ':app:debugRuntimeClasspath'.
Could not determine artifacts for com.android.support:support-fragment:27.0.2: No cached version available for offline mode

If I update compileSdkVersion 27 and targetSdkVersion 27, I get the original error

[samtstern]

@hiddeneyes02 are you working offline?

Can you try running from the command line:
./gradlew clean cleanBuildCache :app:assembleDebug

[dzboot02]

With the same error. I should tell you the error occurs when trying to run the app, not when synchronizing gradle.

[samtstern]

@hiddeneyes02 I am a bit stumped here, and I think it's very strange that I have not seen this same error from any other users.

[samtstern]

@hiddeneyes02 I just recreated your exact project and here's how you can fix it:

Replace this:

classpath 'com.google.gms:google-services:3.2.0'

With this:

classpath 'com.google.gms:google-services:3.2.1'

[dzboot02]

It does do it for me neither, same error is appearing.

[mars885]

Hello everyone! I have the same problem as @hiddeneyes02 has described. Did you find a solution?

[dzboot02]

@mars885 No unfortunately... I didn't use this library because I needed to finish my project. I used Facebook and Google Signin separately.

[sunilson]

I don't know if it was the same error but my problem was that I added Firebase UI Auth and Firebase Auth in Gradle, but Firebase Auth already comes with Firebase UI Auth. So after I removed the Firebase Auth SDK it worked again

[marvin68]

Tried creating a fresh project and only importing google services + Firebase UI auth and the same error happens.

[Diae-dm1303866]

Same error is happening to me as well! :(
I have tried every single thing, but noting seems to work! :(
