If you would like to integrate the Firebase libraries into one of your own projects, you need to perform a few basic tasks to prepare your Android Studio project. You may have already done this as part of adding Firebase to your app.

First, add rules to your root-level build.gradle file, to include the google-services plugin and the Google's Maven repository:

buildscript {
// ...
dependencies {
    // ...
    classpath 'com.google.gms:google-services:4.2.0' // google-services plugin
}
}

allprojects {
// ...
repositories {
    // ...
    google() // Google's Maven repository
}

}

Then, in your module Gradle file (usually the app/build.gradle), add the apply plugin line at the bottom of the file to enable the Gradle plugin:

apply plugin: 'com.android.application'

android {
// ...
}

dependencies {
 // ...
implementation 'com.google.firebase:firebase-core:16.0.6'

// Getting a "Could not find" error? Make sure you have
// added the Google maven respository to your root build.gradle
}

// ADD THIS AT THE BOTTOM
apply plugin: 'com.google.gms.google-services'
