java - 如何在android中获取Facebook信息

Question

我正在尝试从 Android 中的 facebook 获取信息，我的代码:

loginButton.setReadPermissions(Arrays.asList("email", "user_photos", "public_profile"));
    loginButton.registerCallback(callbackManager, new FacebookCallback<LoginResult>() {
        @Override
        public void onSuccess(LoginResult loginResult) {
          Toast.makeText(getApplicationContext(),""+loginResult.getAccessToken(),Toast.LENGTH_SHORT).show();
            String accessToken = loginResult.getAccessToken().getToken();
            GraphRequest request = GraphRequest.newMeRequest(loginResult.getAccessToken(), new GraphRequest.GraphJSONObjectCallback() {
                @Override
                public void onCompleted(JSONObject object, GraphResponse response) {
                    Log.i("LoginActivity", response.toString());
                    // Get facebook data from login
                    try {
                        object.get("gender");
                        object.get("email");
                    } catch (JSONException e) {
                        e.printStackTrace();
                    }
                 //   Bundle bFacebookData = getFacebookData(object);
                }
            });
            Bundle parameters = new Bundle();
            parameters.putString("fields", "id, first_name, last_name, email,gender, birthday, location"); // Parámetros que pedimos a facebook
            request.setParameters(parameters);
            request.executeAsync();

        }

但是程序没有进入 `public void onCompleted(JSONObject object, GraphResponse response) {该函数的结果是:

{Request:  accessToken: {AccessToken token:ACCESS_TOKEN_REMOVED permissions:[email, user_photos, public_profile]}, graphPath: me, graphObject: null, httpMethod: GET, parameters: Bundle[{}]}

有什么解决办法吗？或者这个案例与 Facebook 隐私设置有关？

尝试手动构建登录流程。这样您就不会陷入 sdk 的困境。
