Is there a way to like a profile picture from Facebook SDK OR API (PHP or Android).
I want an user who logs in to see list of other people on Facebook, and be able to like their photo from within the app.
EDIT:
I have looked at the Facebook Graph API, but I had no prior experience. I am not asking you to give me code, I am asking you a simple question - can it be done? Because I have not seen any way of liking profile pictures from php or Android.
