Question

I have a PhoneGap app, where I need to list all the user’s friends, who have authorized the application on Facebook.

I’m currently using FB.api('/me/friends?fields=installed', callbackFnc), but this shows me all friends, pointing which of them have authorized the app. When I really wanted to list only the authorized ones.
This slows a lot the process of loading friends.

I saw other similar questions here, but none of them had the answer.

SOLUTION: Thanks to CBroe
I couldn’t have sucess passing the FQL directly to FB.api, but only using that object:

var apiQuery = 
{
   method: 'fql.query',
   query: 'SELECT uid, name FROM user WHERE uid IN (SELECT uid1 FROM friend WHERE uid2 = me() ) AND is_app_user'
}   

FB.api(apiQuery, function(response){...});

Answer 1

Use FQL instead:

SELECT uid, name FROM user WHERE uid IN
  (SELECT uid1 FROM friend WHERE uid2 = me() ) AND is_app_user

(You can set up that query against the Graph API as well, /fql?q={query}.)
