That's an extremely old version of FirebaseUI. Have you considered upgrading to the latest? — Doug Stevenson, Sep 26 '18 at 22:35

raise the minimum API level from 15 to 16 in the module's build.gradle.

android {
    defaultConfig {
        minSdkVersion 16
    }
}

tools:overrideLibrary is not really an option, because it will crash on devices with API level 15.

This is because FirebaseUI requires API 16 or above to run, while your app's minSdkVersion is set at 15. If Android Studio let you build like this, your app would just crash for users on API 15.

The comments suggest using the tools:overrideLibrary Manifest field, but I don't recommend doing this, because of the reasons described above. You'd have to implement your own authorization UI for API 15 users.

According to Google, 0.3% of active Android users are currently using API 15. This is only devices with the Play Store installed, but it's a pretty good representation of the total portion of Android users running API 15. If you're implementing FirebaseUI, it simply isn't worth it to make your own Auth UI for 0.3% of the total number of Android users.

The easiest and most sensible solution would probably be to just change your minSdkVersion to 16. You're already missing out on the other 0.3% of users on API 10-14. Another 0.3% is nothing.
