title: Facebook Audience Network missing file 'fb_an_config.plist'
body: <p>I am implementing Facebook Audience Network for IOS through Admob Mediation.</p>
  
  <p>I have installed the following POD files:</p>
  
  <ul>
  <li>pod 'Google-Mobile-Ads-SDK', '~> 7.0' </li>
  <li>pod 'FBSDKCoreKit' </li>
  <li>pod 'FBSDKLoginKit'</li>
  <li>pod 'FBSDKShareKit'</li>
  <li>pod 'FBAudienceNetwork'</li>
  </ul>
  
  <p>I have added the libAdapterFacebook.a (Facebook Adapter for Admob Mediation)</p>
  
  <p>When I run the app I got the following log:</p>
  
  <blockquote>
    <p>[FBAudienceNetworkLog/FBAdConfigManager:78 ] Failed to load local configuration: Error Domain=NSCocoaErrorDomain Code=260 "The file “fb_an_config.plist” couldn’t be opened because there is no such file."

  </blockquote>
  
  <p>I did not find in any documentation the need to create this file: <b>fb_an_config.plist</b></p>
  
  <p>Somebody can help me on that?</p>
