Why is Facebook session state always close?

Question

I want to add the Facebook login feature to my application. Note:

• I do not want to use the Facebook login button widget.
• I copied my code that worked correctly last year (from my other project) into my new project.
• I checked Session and I think I have no problem.

The only difference: Request.executeMeRequestAsync()hss has been changed to Request.newMeRequest(). I made this change, but it seems that my session is always closed, although I could see that the method Session.setActiveSession(session);starts by debugging the project. So, I do not know why sessionit is always close in the method call().

Any idea would be appreciated. Thank.

My code is:

public class FacebookLogin extends FragmentActivity
{
    private static final String TAG = "FacebookLogin";

    private static final List<String> READ_PERMISSIONS =
            Arrays.asList("email", "user_about_me", "user_photos");
    //    private static final List<String> WRITE_PERMISSIONS = Arrays.asList("");


    private final Session.StatusCallback statusCallback = new Session.StatusCallback()
    {
        @Override
        public void call(final Session session, SessionState state, Exception exception)
        {
            if (session.isOpened())
            {
                // make request to the /me API
                Request request = Request.newMeRequest(session, new Request.GraphUserCallback()
                {
                    // callback after Graph API response with user object
                    @Override
                    public void onCompleted(GraphUser user, Response response)
                    {
                        if (user != null)
                        {
                            MyLog.d(TAG, "User name: " + user.getName() + "!, Login successfully :)");
                            MyLog.d(TAG, "User id: " + user.getId());
                            MyLog.d(TAG, "Access token is: " + session.getAccessToken());
                            MyLog.d(TAG, "Application id: " + session.getApplicationId());
                            MyLog.d(TAG, "JSON Object: " + user.getInnerJSONObject());

                            SpStorage.setKeyFacebook(FacebookLogin.this, session.getAccessToken());
                            SpStorage.setFacebookUserId(FacebookLogin.this, user.getId());

                            // erson person = parseJSON(user.getInnerJSONObject().toString());
                            // registerUser();

                            // Close activity
                            FacebookLogin.this.finish();
                        }
                    }
                });
                request.executeAsync();
            }
            else if (state.isClosed()) {
                MyLog.d(TAG, "Facebook session closed");
            }
        }
    };

    @Override
    protected void onCreate(Bundle savedInstanceState)
    {
        super.onCreate(savedInstanceState);

        // Find device hash key (should not be used in production)
//        printHashKey();

        // start Facebook Login
        openActiveSession(this, true, statusCallback, READ_PERMISSIONS);
    }

    private static Session openActiveSession(Activity activity, boolean allowLoginUI,
            Session.StatusCallback callback, List<String> permissions)
    {
        Session.OpenRequest openRequest = new Session
                .OpenRequest(activity)
                .setPermissions(permissions)
                .setCallback(callback);
        Session session = new Session.Builder(activity).build();
        if (SessionState.CREATED_TOKEN_LOADED.equals(session.getState()) || allowLoginUI)
        {
            Session.setActiveSession(session);
            session.openForRead(openRequest);
            return session;
        }

        return null;
    }
}
