回答1:

There are a few common sources of this error:

1. Do you have your Play Games App ID properly defined in your AndroidManifest.xml? It should look like this:

In your application tag:

<meta-data android:name="com.google.android.gms.games.APP_ID"
          android:value="@string/app_id" />

2. In the Google Play Developers console, have you added all of the correct accounts in the Testers tab? Any Google account that wants to use your application before it is published must be registered here.

3. Have you (properly) created a Client ID for your application? For Games make sure to do this in the Google Play Developer Console through the Linked Apps tab and not the Google Developer Console.
