Same issue as #1274, but not sure that was ever resolved ... something is pulling in the wrong version of the support library where AppCompatActivity is not a LifecycleOwner.

Hi Sam, Its true same issue as #1274, I have followed your recommendation, but it did't work. I have three apps all of them using firebase-ui they are all fine, with version 3.1.0.

Ah wait, now I see this:

 configurations.all {
        resolutionStrategy.eachDependency { DependencyResolveDetails details ->
            def requested = details.requested
            if (requested.group == 'com.android.support') {
                if (!requested.name.startsWith("multidex")) {
                    details.useVersion '26.0.2'
                }
            }
        }
    }

That's forcing all your support dependencies to be overridden at version 26.0.2! Please update that to something like 27.0.1.

As you can see in the release notes, 3.1.0 was one of the last versions that depended on 26.x so that's why it used to work: https://github.com/firebase/FirebaseUI-Android/releases?after=3.1.2
