title: Facebook Audience Network Proguard settings
body: <p>I'm currently using Proguard in my app, and the Audience Network is not working. I need some different configuration, rather than the usual:</p>
  
  <pre><code>-keep class com.facebook.** { *; }
  </code></pre>
  
  <p>The problem is the integration guide doesn't refer any kind of Proguard configuration. Does someone already faced this problem and figured out what is missing?</p>
