If we refer to the actual error as shown in your log output, the problem is caused by the application ID declared in your Manifest which is actually one of the top setup mistakes committed by developers as shown in this video [this video] . To troubleshoot this kind of error, please check the following: For Android: please verify that the value of the @string/app_id resource matches your application's numeric ID. The value of this resource should only contain digits. For example: <string name="app_id">123456789012</string> Warning : Do not use the full client ID ( 1233456789012.apps.googleusercontent.com ) as your app ID. This will result in errors. For iOS: The application_ID is the number that

We found the answer ourselves. We messed up the configuration in the Google Play Developer console and in the Google API console . Observations: We noticed that our app had different OAuth2 Client IDs, e.g.: Google Play Developer Console, Linked apps detail view 121212121212-4k97si3bnwertwertwet78oj571nl81ce3.apps.googleusercontent.com Google API Console, Credentials, OAuth 2.0 client IDs 121212121212-h25jh8qrps8awertwetertwetweagp3n3t.apps.googleusercontent.com We also saw that we had a lot of errors coming from the Google Play Games Services when we looked in the Dashboard of the Google API console .

Now I can answer my question officially: I fixed it. Apparently if you go to the API console and change the Oauth from there the game services doesn't detect it. I originally put in the wrong SHA1 and fixed it through the API and not the google services developer console. [this video] (it's problem #6 which is really n)

Where did you create the OAuth 2.0 client for your app? From your screenshot it seems that this is the entry in the Google API console . Did you also create an entry in the Game services section in the Google Play Developer console (see step 2 in the Google documentation [LINK] )? I had big problems with my current game, because I created the OAuth 2.0 client manually in the Google API console and not in the Google Play Developer console and the OAuth 2.0 IDs in both consoles didn't match. According to a video [this video] from Google Developers OAuth 2.0 clients should only be created in the Google Play Developer console . I wrote more about what I did wrong in this post [LINK] .

You mentioned that you published your app. Note that game settings should also be published. If you haven't done yet, follow these recommendations when setting up your game [LINK] to use the Google Play games services.

To create this association, you should first link your app with the game as described in Create a linked application [LINK] . Use the correct application ID in Android The application ID is a required string resource that you
