Google+ login on Android Studio - GoogleAuthException: BadUsername

After successfully logging in, I cannot get the profile information and keep getting the error in the GoogleAuthUtil.getToken () method.

Mistake:

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

      

        
        
        
      

    

The Android Client ID is derived automatically from the combination of the Android package name and the SHA-1 fingerprint of the signing key in the developer console project. I matched the package name and even tried the entire debug.keystore file I have on my workstation. Nothing succeeded.

* The consent screen is installed (!), But not displayed.

The whole working snippet:

public class GooglePlusActivity extends Fragment implements ConnectionCallbacks, OnConnectionFailedListener {

private static final String TAG = "SignInActivity";

// magic number use to know that sign-in error
// resolution activity has completed.
private static final int REQUEST_RESOLVE_ERROR = 9000;

// core Google+ client.
private GoogleApiClient mGoogleApiClient;

// flag to stop multiple dialogues appearing for the user.
private boolean mResolvingError;

//TOKEN 
protected String mToken;

      .addApi(Plus.API, options)
      .addConnectionCallbacks(this)
      .addOnConnectionFailedListener(this)
      .build();

    // the resolution of a connectionFailed ConnectionResult.

    }
}

    mGoogleApiClient.disconnect();
}

    Log.i(TAG, "ConnectionFailed : " + result.toString());

What am I doing wrong?
