google oauth – GoogleAuthException: Unknown (android)-ThrowExceptions

Exception or error:

I have android, google authorization issue (similar to .GoogleAuthException: Unknown while doing Google SSO. – no answers):

09-29 00:04:38.328: W/System.err(15623): Unknown
09-29 00:04:38.328: W/System.err(15623):    at Source)

It is reproducable when i execute the following code:

String scopesString = Scopes.PLUS_LOGIN + " " + Scopes.PLUS_PROFILE;
String scopes = "oauth2:server:client_id:" + Consts.GOOGLE_PLUS_SERVER_CLIENT_ID + ":api_scope:" + scopesString;
String scopes = "audience:server:client_id:" + Consts.GOOGLE_PLUS_SERVER_CLIENT_ID;
Bundle appActivities = new Bundle();
appActivities.putString(GoogleAuthUtil.KEY_REQUEST_VISIBLE_ACTIVITIES, "");
GoogleAuthUtil.getToken(activity,  accountName, scopes, appActivities);

Here are some notes:

  1. I can get access token with GoogleAuthUtil.getToken(activity, accountName, “oauth2:” + scopesString)
  2. activity != null, client_id =, accountName is valid email (selected with account picker)
  3. accountName in has a record about my project: <Project Name> ——- app and purchase activity——–Your circles
  4. I have android.permission.GET_ACCOUNTS
  5. The same exception with appActivities.putString(GoogleAuthUtil.KEY_REQUEST_VISIBLE_ACTIVITIES, “”)
  6. The same exception with GoogleAuthUtil.getToken(activity, accountName, scopes)


  1. You should have 2 Client Ids: Installed App (Android) and Service one. You should use Service one here.
  2. Then you will get UserRecoverableAuthException: NeedPermission. You should handle exception

i.e. like this:

} catch (UserRecoverableAuthException e) {
activity.startActivityForResult(e.getIntent(), REQUEST_AUTHORIZATION);
How to solve:

In the Google Developer Console, in the APIs & Auth section click Credentials.

You probably already have a “Client ID for Android application” and are using that Client ID. What you have to do is create a new Client ID and select “Service Account” for your backend.

You must use this Client ID, and not the Android one.


I was getting the Unknown error because I registered my SHA1 hash using my release keystore. Registering a new app using a debug keystore fixed my issue.


Change the scope added in GoogleApiCliente to Plus.SCOPE_PLUS_LOGIN. This work for me.

googleApiClient = new GoogleApiClient.Builder(this)


For me it happened when I changed the “applicationId” in the gradle file. Make sure you have the same applicationId or packagename in the developer console when you enabled the API.
