Prerequisites

1. The Latest Version of Android Studio

The easiest way to connect to Firebase is through the Firebase Assistant in Android Studio.

1. Connecting using Firebase Assistant

1. Create an account in the Firebase Console. Click add project to add your Android Studio project to it.

2. Install Google Repository You can do this by adding the dependency into your project-level build.gradle file, as shown below:

allprojects{
  repositories {
        maven {
            url "https://maven.google.com" // Google's Maven repository
        }
    }
}

Alternatively, you could do that using the GUI.

3. Go to Tools > Firebase and select Connect to Firebase

If you wish to connect to Firebase manually, detailed instructions are available here.
Having connected your Android Studio project to Firebase, you can either

1. click on a product in the Firebase Assistant to get to the appropriate Google docs where you will be told how to proceed.
2. go to desired product in Project Overview in the Console and click on Get Started.
3. go to the Firebase docs to see how to setup individual products in your project.

Reading a combination of all three will enable you to setup the product, which includes adding suitable dependencies to your build.gradle file.
