title: Several new Proguard issues Google Play services v10.2.6 to v11.0.0 in a Multidex project
body: <p>I updated our app to use the most recent Android Firebase SDK v11.0.0 (<a href="https://firebase.google.com/support/release-notes/android#20170607" rel="noreferrer">https://firebase.google.com/support/release-notes/android#20170607</a>) and out of the suddenly we bunch of new proguard errors appear, FYI everything was working well before with proguard.</p>
  
  <p><strong>Before:</strong></p>
  
  <pre><code>compile 'com.google.firebase:firebase-messaging:10.2.6'
  compile 'com.google.android.gms:play-services-vision:10.2.6'
  </code></pre>
  
  <p><strong>After:</strong></p>
  
  <pre><code>compile 'com.google.firebase:firebase-messaging:11.0.0'
  compile 'com.google.android.gms:play-services-vision:11.0.0'
  </code></pre>
  
  <p>The issue is that it doesn't seem to be a simple new missing proguard entry, but it seems that it broke the whole thing, suddenly several other libraries appeared to be affected by this change.</p>
  
  <p><strong>These are the Proguard issues related to the GMS:</strong></p>
