GraphUser object returns null "getUserName" while fetching friends from facebook in Android

Question

In my android application i want to fetch my facebook friends and for that i am using facebook-android-sdk-3.7. I referred FriendPickerSample which is provided by facebook-android-sdk itself. Here, it returns friendlist as a list of GraphUser. Now, i want to fetch username of all friends but the problem is that it doesn't provide username of friendlist. It provides all other personal information of friends except userName.So what should i do to get username of friends? Please suggest any solution for that. Thank you.

Answer 1

I'm not sure what's the code inside that sample which is fetching the user details, so I can not suggest you some changes to fetch the username.

Anyways, that sample must be providing you the user_id. So, you can make this call to get the username of that friend-

/{user-id}?fields=username
