title: android getting all user's friend profile pictures quickly
body: <p>I'm looking for a quick way of getting all my friends's profile pictures.
  I'm using the Facebook SDK for Android.</p>
  
  <p>right now I'm getting my friend's list JSON object and running with a for loop inside this object.
  in the loop i'm putting each image in a Drawable object from the: <a href="http://graph.facebook.com/uid/picture" rel="nofollow noreferrer">http://graph.facebook.com/uid/picture</a>.</p>
  
  <p>I've seen that each picture weight only 4K and it goes fast for few friends.
  but what if I have 1000 friends and i'm connecting to facebook for each one of them?
  it will take lots of time.</p>
  
  <p>I've seen in other application that some of them show all your friend real quick.</p>
  
  <p>what is the best way of doing it? using the runner?</p>
