title: How can I tell which classes Proguard warns me about?
body: <p>I am trying to release my app and ProGuard is causing all sorts of errors with my server code so I went into the gradle console and see this:</p>
  
  <pre><code>Note: there were 2 references to unknown classes.
    You should check your configuration for typos.
    (http://proguard.sourceforge.net/manual/troubleshooting.html#unknownclass)
  Note: there were 26 unkept descriptor classes in kept class members.
    You should consider explicitly keeping the mentioned classes
    (using '-keep').
    (http://proguard.sourceforge.net/manual/troubleshooting.html#descriptorclass)
  Note: there were 22 unresolved dynamic references to classes or interfaces.
    You should check if you need to specify additional program jars.
    (http://proguard.sourceforge.net/manual/troubleshooting.html#dynamicalclass)
  Note: there were 15 accesses to class members by means of introspection.
    You should consider explicitly keeping the mentioned class members
    (using '-keep' or '-keepclassmembers').
    (http://proguard.sourceforge.net/manual/troubleshooting.html#dynamicalclassmember)
  </code></pre>
  
  <p>That's all fine and dandy, but how the heck do I know which specific references ProGuard is talking about? Surely they don't expect me to find/remember these references independently?</p>
