Get user Friends GraphLocation with Android - Facebook SDK and GraphUser

Question

I am having some troubles to get the location data from the end-user Facebook friends list on my Android application.

So far I can successfully open a Facebook Session, store & restore the access token and fetch the user friends list.

As defined in the Android Facebook SDK >3.0, a Facebook user data is strongly-typed in an Object called GraphUser.

To fetch the Friends List, I user Request.newMyFriendsRequest which, upon success, provides me with a list of GraphUsers.

Unfortunately, though I provided the necessary permissions for my endeavor, I fail to retrieve more than the end-user friends names and ID... that's all : each end-user Facebook friend is a GraphUser that contains only their name and their ID.

Here is the list of permissions I use :

"user_status", "read_friendlists", "email", "user_location", "friends_location"

Using the Facebook LoginButton, the SDK tells the end-user that the app does require the aforementioned list of permissions.

Bu when I want to use Graphuser.getLocation, I do get null value. No city, not state, no ZIP code, no nothing.

This is the code snippet to retrieve the end-user data :

public final void setCurrentUser(final Context context) {
    if (this.session != null && this.session.isOpened()) {
        final Request requestCurrentUserProfile = Request.newMeRequest(
                this.session, new Request.GraphUserCallback() {
            public final  void onCompleted(final GraphUser user, final Response response) {
                currentUser = user; // currentUser is defined as a class member
                if (response.getError() != null ) {
                    // TODO
                }
            }
        });
        requestCurrentUserProfile.executeAsync();
    } else
        this.currentUser = null;
}

Placing a break-point here, with the debugger, the GraphUser representation is complete : I have all the data that I need, including the location !

Regarding the end-user Friends list ...

public final void fetchFriendsList() {
    if (this.session != null && this.session.isOpened()) {
        final Request requestUserFriendsList = Request.newMyFriendsRequest(
                this.session, new Request.GraphUserListCallback() {
                    public final void onCompleted(final List<GraphUser> users, final Response response) {
                        if (users != null && users.size() > 0)
                            userFriendsList = new ArrayList<GraphUser>(users);
                    }
                }
        );
        requestUserFriendsList.executeAsync();
    }
}

This is where the users are almost empty : just a name and an ID. That's it, that's all.

Perhas this Request doesn't provide more data ?

If so, which method should I use to fetch the data I need ?

Thanks !

[EDIT]

Looking at my app review status I'm not even suppose to rerieve the Friends List nor the location data of the current end-user ?? !

List of Permission for my App

What is happening here ? I don't get it ... please help !

[EDIT2]

To show you the difference between the end-user GraphUser and the end-user friends list GraphUsers, here is a screenshot of the debugger. Fields have been intentionnaly removed for privacy reasons.

You might have to explicitly request those fields in the request parameter when asking friend's data.

Like this,

private void makeMyFriendsRequest(final Session session) {
    Request request = Request.newMyFriendsRequest(session, new Request.GraphUserListCallback() {
        @Override
        public void onCompleted(List<GraphUser> users, Response response) {
            // If the response is successful
            if (session == Session.getActiveSession()) {
                for (GraphUser user : users) {
                    System.out.println(user.getFirstName() + " " + user.getLastName());
                    System.out.println(users.get(i).getId());
                    GraphLocation loc = users.get(i).getLocation();
                    System.out.println(loc != null ? loc.getCity() : "loc not available");
                }
            }
        }
    });

// here add fields explicitly
Bundle bundle = request.getParameters();
bundle.putString("fields", "id,first_name,last_name,birthday,location");
request.executeAsync();

I hope this will help.

PS: I assume that you're requesting your permissions with login button like this,

loginButton.setReadPermissions(Arrays.asList("user_location", "friends_location"));
