I started to use google play services in my project some time ago. The error is appearing randomly. When I go to Window/Google Play Games/Setup/Android Setup... and than click Setup the error is gone, but after few compilations it appears again. I don't know what can be causing this issue.
I though it is related to Google Play Games, but it didn't happen before so I'm not sure if it is the case.

I can build the project with this error and it seems to work, but it's annoying. What I can do to track the issue?
