Problem with sample for Android

[UlyssesGomes]

Hello everybody,

I downloaded this project and set up an API_KEY for it, a json file was also generated. I placed the key in the manifest and the json file inside the app's project folder. But an error is happening and displaying the following message in the log:

GoogleAuthException: com.google.android.gms.auth.GoogleAuthException: UNREGISTERED_ON_API_CONSOLE

This message appears when I press the "SCAN" button of the application. Could someone give me a hint how to solve this problem?

I would greatly appreciate some help with this.

Go to Gradle tab and in your app module click signingReport and run the app that will generate and run a command on terminal and will show result which contains SHA1. Copy SHA1 and in your developers console paste that in your Auth2 credentials also copy the package name from your project manifest into developers console save it and the exception should be gone!
