Create a new project in android studio. Now, in your app-level build.gradle file, add

implementation 'com.google.android.gms:play-services-auth:16.0.1'

Now sign in to your google account from browser and open configure your project

Go to Gradle that is present at right side in your android studio window, click on it. So it will show a tree structure. Select ApplicationName → ApplicationName (root) → Tasks → android → signinreport Now, run that signinreport by double clicking on it. Now you can see that SHA - 1 key is generated in Run windnow. Copy that key and paste in google API Console.

Click on next and then download configuration file. Now paste that credentials.json file into your app directory.
