Question

My Android app is retreiving the user’s friends list and displaying it to them alongside their profile pics. At the moment I’m refreshing all the pictures from the server every time which is a waste of bandwidth. Is there a way to query when the picture was last updated?

Answer 1

You don’t need to retrieve their pictures at all. Just specify the image’s src like http://graph.facebook.com/zerkms/picture, where zerkms is user’s name or id

UPD: if so – then no. The only thing could help you is updated_time field of user’s profile, which is changed when user has changed anything in his profile (and probably at wall, not sure)

There is a Realtime API that can notify about particular user profile changes but it will not help you in your case
