title: Error: AGPBI: Program type already present: com.google.android.gms.auth.api.signin.internal.zzg
body: <p>In my Adrdoi app, where I use Google Login and Firebase Cloud Messaging, I get this error message:</p>
  
  <pre><code>AGPBI: {"kind":"error","text":"Program type already present: com.google.android.gms.auth.api.signin.internal.zzg","sources":[{}]}
  </code></pre>
  
  <p><strong>Does that mean that the google auth lib was already used somewhere else? Whats that from?</strong></p>
