Question

I\'m experiencing a build issue when adding a firebase dependency to a android library.

My setup is as follows

/settings.gradle

Answer 1

Upgrading the google-services plugin to version 4.0.1 fixed the issue.

From the Firebase sdk changelog page: https://firebase.google.com/support/release-notes/android

In other words, change this:

classpath 'com.google.gms:google-services:4.0.0'

to this:

classpath 'com.google.gms:google-services:4.0.1'
