Facebook friends that have installed my app

I'm trying to retrieve a list of ids for friends that've installed my apps. I'm currently using this query, but it's returning 0 friends... Why is that?

GraphRequest request = GraphRequest.newGraphPathRequest(
                        token,
                        "/"+ facebookUserId +"/friends", response -> {
                            User newUser = new User();

                            if (response.getError() != null) {
                                //TODO: Handle error gracefully
                                Log.e("TEST", response.getError().getErrorMessage());
                                return;
                            }

                            try {
                                JSONArray listOfFriendsJson = response.getJSONObject()
                                        .getJSONArray("data");
                                Log.i("TEST", "Found " + listOfFriendsJson.length() + " friends");

                                for (int i=0 ; i < listOfFriendsJson.length() ; i++) {
                                    JSONObject friendJson = listOfFriendsJson.getJSONObject(i);
                                    newUser.friends_list.put(friendJson.getString("id"), true);
                                    Log.i("TEST", friendJson.getString("id"));
                                }
                            } catch (JSONException e) {
                                Log.e(LOG_TAG, "Error parsing response of GraphRequest", e);
                                //TODO: Stop loading and show error
                            }

                        });

...Apps requesting the following permissions are now subject to heightened scrutiny during Login Review:

  • ...
  • user_friends
  • ...

I assume that the user_friends permission did not show up in the login dialog for your friend. Try adding your friend as Tester in the App settings and go through the login process again. Make sure you get asked for the user_friends permission on both phones.
