title: Android Google sign in not working on another computer
body: <p>I have generated google-services.json with my SHA-1, created web and android OAuth tokens (use web in .requestIdToken() method). And everything working like a charm.
  But when colleagues pull it from git, error 12501 is here ...</p>
  
  <p>Should they create their own google-services.json by their SHA, or where is the problem?</p>
