Prerequisites

1. The Latest Version of Android Studio

The easiest way to connect to firebase is to use the firebase assistant.

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 like this:

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 and get taken to the 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.

If You Encounter Gradle Sync Try To Change The Firebase-core Version or Firebase-database version
