Creating an Android Project

Open Android Studio (Here I am using Android Studio 3.0). And you need to create a project with an Empty Activity. I created a project named GoogleLoginExample.
Once your project is loaded then click on Tools->firebase

Then you will see a new window on the right. Here you need to select Authentication.

Now you need to connect to firebase. It will again open a window, and from this window, you can create a new Firebase Project, or if you want you can also choose an existing one.

After connecting to Firebase, click on Add Authentication and accept the changes. It will add all the required dependencies.

If we want to use Google Login with Firebase, then we also need to enable it in the Firebase Console (Default disables it).
To enable it, go to Firebase Console (console.firebase.google.com). Then from the right, select Authentication, then select SIGN-IN METHOD, and here you need to allow Google Option. (See the image below it is disabled, and you need to enable it).
