Android应用Facebook登录返回空值或什么也没有

Question

我现在有一点这个问题而且我似乎无法找到解决方案。我已经尝试了图形API以及Profile跟踪器。两者似乎都在提出问题。 Graph API允许应用程序使用用户ID的空对象引用进行崩溃，并且在使用配置文件跟踪器时，应用程序不会继续超出该部分。

这是我的代码，其中跟踪器已注释掉，并且正在使用图形API。

loginButton.registerCallback(callbackManager, new FacebookCallback<LoginResult>() {
            @Override
            public void onSuccess(LoginResult loginResult) {
                /*if(Profile.getCurrentProfile() == null) {
                    profileTracker = new ProfileTracker() {
                        @Override
                        protected void onCurrentProfileChanged(Profile profile, Profile profile2) {
                            // profile2 is the new profile
                            Mint.leaveBreadcrumb("Login Activity ~ Waiting for facebook to return profile");
                            Log.v("facebook - profile", profile2.getFirstName());
                            profileTracker.stopTracking();
                        }
                    };
                    // no need to call startTracking() on mProfileTracker
                    // because it is called by its constructor, internally.
                }
                else {
                    Profile profile = Profile.getCurrentProfile();
                    Mint.leaveBreadcrumb("Login Activity ~ Current Profile" + profile);
                    Mint.leaveBreadcrumb("Login Activity ~ Current FBID" + profile.getId());

                    SetUserData();
                    LogIn();
                    ///
                    continueToAdverts();
                }*/

                GraphRequest request = GraphRequest.newMeRequest(loginResult.getAccessToken(),
                        new GraphRequest.GraphJSONObjectCallback() {
                            @Override
                            public void onCompleted(JSONObject object, GraphResponse response) {

                                try {

                                    //String name = object.getString("name");
                                    //String email = object.getString("email");
                                    //String id = object.getString("id");
                                    //Toast.makeText(MainActivity.this, name + " " + " " + email + " " + id, Toast.LENGTH_SHORT).show();

                                    AppGlobal.LoggedUser = new UserInfo();
                                    AppGlobal.LoggedUser.setFacebookId(object.getString("id"));
                                    SetUserData();
                                    LogIn();
                                    ///
                                    continueToAdverts();

                                } catch (JSONException ex) {
                                    ex.printStackTrace();
                                }
                            }
                        });
                Bundle parameters = new Bundle();
                parameters.putString("fields", "id,name,email");
                request.setParameters(parameters);
                request.executeAsync();
            }

            @Override
            public void onCancel() {
                // App code
            }

            @Override
            public void onError(FacebookException exception) {
                // App code

            }
        });

我错过了什么吗？
