title: ANR caused by com.google.android.gms.DynamiteModules
body: <p>I am using Firebase inside my app with Facebook authentication. After the 3th restart of my app, it freezes and then shows an ANR (please see my <a href="https://stackoverflow.com/questions/37396811/loginactivty-with-firebase-facebook-authentication-not-responding-after-3th-re">last question</a>). After some doing some research i found out that something is blocking the main thread. I have no clue why this is happening. The error below show up a couple of times when my app is running (my app does not freeze when this error appears). Does anyone have an idea?</p>
  
  <p>I have included some info below, maybe it helps</p>
  
  <p>Note: Google play services on test device (Samsung SM-G920F) is running version: 9.0.83 (440-121911109)</p>
