title: Prefetching Images for Facebook's Native Ads for Android
body: <p>I've been playing a while with the latest release of Facebook's SDK for Android. In particular, I've been trying out the Native Ad API. My problem is I want to be able to preload several ads (lets say 3 or 5 or 10, doesn't matter), so they appear the instant they appear on screen. I've managed to do this but I've got stuck with the images. Apparently, the images (icon and coverImage) can only be obtain via the <code>NativeAd.downloadAndDisplayImage</code> which requires the imageView where the images will be displayed. </p>
  
  <p>Is there anyone having this same kind of issue? Anyone who has played/worked with the Native Ad API in Android and can give me some insight?</p>
  
  <p>It's kinda difficult since I can't look into the source code of the AudienceNetwork library yet, plus there's no javadoc. I've tried googling around but with no success.</p>
