Having the same issue. This shouldn't be needed, however once it's connected via Android Studio, it no longer needs specific URLs.

A problem occurred evaluating project ':app'.

Could not get unknown property 'UniqueFirebaseRootUrl' for object of type com.android.build.graddle.AppExtension
BUILD FAILED
