Hello everybody,

I have a display problem with my facebookConnection. I have a connection class with inscription class. with my app, it's possible to use the facebook connection.

But when i click the facebook button in order to load the home page when the connection has success, i see nothin after the facebook login ( fb.doLogin () ) . 

b_fcb.addActionListener((e) -> {

            String clientId = "xxxxxxxxxxxxxxxxxx";

            String redirectURI = "https://www.facebook.com/";

            String clientSecret = "xxxxxxxxxxxxxxxxxxxxxxxxxxxxx";

            Login fb = FacebookConnect.getInstance();

            fb.setClientId(clientId);

            fb.setRedirectURI(redirectURI);

            fb.setClientSecret(clientSecret);

            Log.p("1");

//            System.out.println("token = "+fb.getAccessToken());

            fb.setCallback(new LoginCallback() {

                @Override

                 public void loginSuccessful() {

                     /*InfiniteProgress ip = new InfiniteProgress();

                    ip.setUIID("InfiniteProgress");

                    final Dialog d = ip.showInifiniteBlocking();*/

                    Preferences.set("token", fb.getAccessToken().getToken());

                    final FacebookData data = new FacebookData();

                    data.fetchData(Preferences.get("token", (String) null), () -> {

                        Display.getInstance().callSerially(new Runnable() {

                            public void run() {

                                Dialog.show("Bravo ", "Bienvenu " + data.getName(), "OK", null);

                                manager.cheminPhoto = data.getImage();

                                manager.fcbLog = data.getName();

                                manager.isFcb = true;

                                manager.setLogin(data.getName());

                                manager.lanceFcbInsc();

                            }

                        });

                 @Override

                 public void loginFailed(String errorMessage) {

                     Form ff = new Form("Echec de connection", new BoxLayout(BoxLayout.Y_AXIS));

                     Label l = new Label("Erreur de connection facebook");

                     ff.addComponent(l);

                     ff.show();

                 }

             });

             

             //trigger the login if not already logged in

             if (!fb.isUserLoggedIn()) {

                 fb.doLogin();

             } else {

                 //get the token and now you can query the facebook API

                String token = fb.getAccessToken().getToken();

            }

        });

please help me.

Hi,
that's not how facebook login works. Native/App login is different from website login. Those are VERY different things.

To use Facebook you need to use the graph API with the received token see https://www.codenameone.com/blog/building-a-chat-app-with-codename-one-part-3.html

I have my hashkey and my facebook login count: https://developers.facebook.com/apps/

[Shai Almog]

If you have your login you can now use the Facebook Graph API webservice to query facebook.

[usabg...@gmail.com]

yes i know that, my facebook queries worked before, but know, i thing that i have all, and my code it's complete. But when  push facebook button in order to launch my home page, i see nothing. that makes me crazy.

[Gareth Murfin]

If you ever get it to work Id love to know how, I had to give up on FB altogether, I tell clients its not an option because i  couldnt get it to work on any level

[usabg...@gmail.com]

I'm trying to find a solution, everydays.

[Gareth Murfin]

good luck, I seem to remember the FK SDK is a nightmare even natively, I had once wrapped it all up entirely into a very simple object that could do everything nicely (for native android) if I can get back to that on Android I will make a lib, but it wont work on iOS.

[Shai Almog]

We have shipping apps with native facebook integration (quite a few) so I'm not exactly sure I understand what you guys are complaining about.
It's painful for sure but it's doable and there is a step by step guide in the developer guide.

[Gareth Murfin]

is the code for any of these apps available? We prob did something stupid, theres some old code around on google i think which confuses matters.

The chat app uses facebook and it's code is in github.
