I am new to developing android apps with facebook functions. Currently my app has the functions for log-in and friend list fetching.
What I want to do is for my app to have its own friendlist (sort of social network) so when the user first logs in, he has no friends, but then he can add them from the list of friends from facebook. However, what I don't want is for the user to send more than one friend request to a single person.
Actually I store the invitations he sends and the friends he already has but when I fetch the Facebook friend list via Graph API it gives me ALL the friends that are using the app and I have to filter it to remove all the current friends and the friends he already send invitations to.
I was wondering if there is some way to create a private facebook list with the friends the user has send invitations to, and then when I fetch the normal friendlist (/me/friends) to automatically remove the ones that are registered in the private friendlist. Or if there is another way to do this and avoid in-app list filering
