===

Hello I neeed to retrieve User Name and notifications from a facebook profile, this is my facebook conector code:

    import com.FeedPass.SessionEvents.AuthListener;
    import com.FeedPass.SessionEvents.LogoutListener;

    public class FacebookConnector {
	private Facebook facebook = null;
	private Context context;
	private String[] permissions;
	private Handler mHandler;
	private Activity activity;
	private SessionListener mSessionListener = new SessionListener();
	private String _accessToken;
	
	public FacebookConnector(String appId,Activity activity,Context context,String[] permissions){
		this.facebook = new Facebook(appId);
		
		SessionStore.restore(facebook, context);
		
		SessionEvents.addAuthListener(mSessionListener);
		SessionEvents.addLogoutListener(mSessionListener);
		this.context=context;
		this.permissions=permissions;
		this.mHandler = new Handler();
		this.activity=activity;
	}
	
	public void login() {
        if (!facebook.isSessionValid()) {
            facebook.authorize(this.activity, this.permissions,new LoginDialogListener());
        }
    }

	public void logout() {
        SessionEvents.onLogoutBegin();
        AsyncFacebookRunner asyncRunner = new AsyncFacebookRunner(this.facebook);
        asyncRunner.logout(this.context, new LogoutRequestListener());
	}

	public void postMessageOnWall(String msg) {
		if (facebook.isSessionValid()) {
		    Bundle parameters = new Bundle();
		    parameters.putString("message", msg);
		    try {
				String response = facebook.request("me/feed", parameters,"POST");
				System.out.println(response);
			} catch (IOException e) {
				e.printStackTrace();
			}
		} else {
			login();
		}
	}	
	
	public String getNotifications(){
		String result = null;
		if(facebook.isSessionValid()){
			Bundle bundle = new Bundle();
			bundle.putString(Facebook.TOKEN, _accessToken);
			try{
				result = facebook.request("me/notifications", bundle, "GET");
			}
			catch(IOException e){
				e.printStackTrace();
			}
		}
		else{
			login();
		}
		return result;
	}

    private final class LoginDialogListener implements DialogListener {
        public void onComplete(Bundle values) {
            SessionEvents.onLoginSuccess();
        }

        public void onFacebookError(FacebookError error) {
            SessionEvents.onLoginError(error.getMessage());
        }
        
        public void onError(DialogError error) {
            SessionEvents.onLoginError(error.getMessage());
        }

        public void onCancel() {
            SessionEvents.onLoginError("Action Canceled");
        }
    }
    
    public class LogoutRequestListener extends BaseRequestListener {
        public void onComplete(String response, final Object state) {
            // callback should be run in the original thread, 
            // not the background thread
            mHandler.post(new Runnable() {
                public void run() {
                    SessionEvents.onLogoutFinish();
                }
            });
        }
    }
	
	private class SessionListener implements AuthListener, LogoutListener {
        
        public void onAuthSucceed() {
            SessionStore.save(facebook, context);
        }

        public void onAuthFail(String error) {
        }
        
        public void onLogoutBegin() {           
        }
        
        public void onLogoutFinish() {
            SessionStore.clear(context);
        }
    }

	public Facebook getFacebook() {
		return this.facebook;
	}
    }

as you can see I have a method to retrieve user notifications but I'm not sure it is working, anyone know how to do this is in a simple manner?
