Answer 2

As Sudhanshu Gaur pointed out in this post, try first generate a signed apk using the same key you used to create your json configuration file. Then install it on your device and see whether it works. The reason is Android Studio does not sign your apk when you click "run".
I was stuck on exactly the same problem and this fix worked fine for me.

Answer 3

Are you using Plus.API or Auth.GOOGLE_SIGN_IN_API? The latter is the latest revamped one. Check it out here: https://developers.google.com/identity/sign-in/android/sign-in

---

If you are using Auth.GOOGLE_SIGN_IN_API:

In onActivityResult, use code similar to below and you can get a status code, which is defined by GoogleSignInStatusCodes: https://developers.google.com/android/reference/com/google/android/gms/auth/api/signin/GoogleSignInStatusCodes

@Override
public void onActivityResult(int requestCode, int resultCode, Intent data) {
    super.onActivityResult(requestCode, resultCode, data);

    // Result returned from launching the Intent from GoogleSignInApi.getSignInIntent(...);
    if (requestCode == RC_SIGN_IN) {
        GoogleSignInResult result = Auth.GoogleSignInApi.getSignInResultFromIntent(data);
        int statusCode = result.getStatus().getStatusCode();
    }
}

The most common issue is missing the right OAuth2 client registration. (Unfortunately, for now, the status code is INTERNAL_ERROR 8, which is not helpful. ) E.g. Take a look at this thread: Occured an INTERNAL_ERROR when requestEmail from GoogleSignInOptions Android

Answer 4

Please insure that you had applied SHA-1 debug key in the google-services.json file creation.

Answer 5

you need to provide the SHA-1 hash of your signing certificate on your app

example:

Registered SHA-1s:

CF:4A:A1:0A:BC:84:F2:31:28:C3:BA:A7:A3:A2:36:10:5F:1D:3E:CB and download the config file you created.. and replace to *yourproject/app/google-service.json

//Get google-service.json file tutorial https://developers.google.com/identity/sign-in/android/start-integrating

//how to get SHA-1 https://developers.google.com/android/guides/client-auth

Answer 6

Please check your SHA-1 added key is debug or release, based on your key its work relatively on it. I have get same issue latte i understand that i have used release SHA-1 and i am testing on debug then it will get false result. Thanks
