I am following the Facebook SDK Scrumptious tutorial. I successfully completed the Login and Personalize steps. Now I am stuck on the Show Me step.
When I click select friends, the list of friends is empty.
I added my brother as a Tester for the app and he clicked accept in his Facebook Developers page. Then, on Eclipse, I ran the application on his phone. But when he clicked Select friends it was still empty. It did not show my name. And when I ran the application on my phone I did not see his name in the friends list.
Does anybody know why I can't see his name on my friends list? The app works on both our phones yet the friends list is empty.
I followed the tutorial step by step.
I believe I am using the correct hashkey since the app opens on both our phones. Is there something new I am supposed to implement and Facebook just hasn't updated their tutorials?
Is it a problem with Eclipse?
