Try adding apply plugin: 'com.google.gms.google-services'line at the bottom of your app/build.gradle file.

As discussed in The Google Services Gradle Plugin, as part of enabling Google APIs or Firebase services in your Android application you may have to add the google-services plugin to your build.gradle file:

dependencies {
    classpath 'com.google.gms:google-services:3.0.0'
    // ...
}

Moreover, the google-services plugin has two main functions:

1. Process the google-services.json file and produce Android resources that can be used in your application's code.
2. Add dependencies for basic libraries required for the services you have enabled. This step requires that the apply plugin: 'com.google.gms.google-services' line be at the bottom of your app/build.gradle file so that no dependency collisions are introduced. You can see the result of this step by running ./gradlew :app:dependencies.
