Facebook authorization issue

Hi,

I am trying to use facebook authorization, so I have followed all the required steps, registered app on facebook, set backendless url there, put all the keys into backendless app settings.
Now I am trying to use loginWithFacebook method.
First of all, what confuses me, is that you provide method loginWithFacebook with only two arguments, context and the responder, however in your documentation, this option is not mentioned.
So ok, I do next

        Backendless.UserService.loginWithFacebook(MainActivity.this, new AsyncCallback<BackendlessUser>() {
            @Override
            public void handleResponse(BackendlessUser backendlessUser) {
                System.out.println("successful facebook login");
            }


            @Override
            public void handleFault(BackendlessFault fault) {
                System.out.println("error during facebook login:" + fault);
            }
        });

and as a result I am getting
INFO/System.out(1785): error during facebook login:BackendlessFault{ code: ‘Server.Processing’, message; ‘unable to find method in class. method name getFacebookServiceAuthorizationUrlLink’ }

So I need your help to make it work.

I have the same error
