Facebook 'Friends.getAppUsers' using Graph API

Question

I have an application that uses the old REST API call Friends.getAppUsers to get the list of friends for the current user that have authorized my application.

Answer 1

Old REST API:

$facebook->api_client->friends_getAppUsers();

New Graph API:

$facebook->api(array('method' => 'friends.getAppUsers'));

Answer 2

Using restFB, I did the following (thanks Igy / Alex for the guidance). Note that Facebook returns an array of friend IDs with "installed"=true if the user is installed (as can be seen here).

First extend the User class, adding an installed field:

import com.restfb.Facebook;
import com.restfb.types.User;

public class InstalledUser extends User {

    @Facebook
    private boolean installed;

    public InstalledUser() {        
    }

    public boolean getInsatlled() {
        return installed;
    }
}

Next, using the DefaultFacebookClient:

FacebookClient facebook = new DefaultFacebookClient(pFacebookAccessToken);
Connection<InstalledUser> installedFacebookUsers = facebook.fetchConnection("/" + pFacebookId + "/friends", InstalledUser.class, Parameter.with("fields", "installed"));        
for (List<InstalledUser> friends : installedFacebookUsers) {
    for (InstalledUser friend : friends) {
        if (friend.getInsatlled()) {
            // Add friend.getId() to a list of ID, or whatever
        }
    }
}
