title: Android get Facebook friends who have app downloaded
body: <p>I am using the Facebook Android SDK. Is there an easy way to get a user's friends who have downloaded the app? For example, the app Draw Something implements this. I can't seem to find any information on this subject</p>
  
  <p>I would guess that if it was possible, some extra information would be needed in the httppost to access this information. </p>
