Facebook friends list returns empty

Question

In my application I'm trying to retrieve the user's friends list. I ask for user_friends permission and check in the activity the the permission is granted. The problem is that the friends list returns empty at any time.

I use the following code:

        Request request = Request.newMyFriendsRequest(_session, new Request.GraphUserListCallback() {

        @Override
        public void onCompleted(List<GraphUser> listFacebookFriends, Response response) {
            Toast.makeText(MainActivity.this, ""+listFacebookFriends.size(), Toast.LENGTH_LONG).show();
            Log.d(TAG, response.toString());
        }
    });

    request.executeAsync();

And the returned response is:

{Response:  responseCode: 200, graphObject: GraphObject{graphObjectClass=GraphObject, state={"data":[]}}, error: null, isFromCache:false}

What can be the problem?

Answer 1

I assume you created your app after 4/30/2014 which means that you are using v2.0 of the API. That means that only friends that are using the app will get returned.
