无法使用Facebook SDK 4.10.0 Android获得用户Facebook feed

Question

我在Android应用程序中使用Facebook登录。 我已经成功登录Facebook，但没有得到特定用户的供稿。 即该用户在Facebook上发布的帖子。

我尝试过的如下

        Profile profile = service.getProfile(social_feed);

        /*Log.e("Watson Response: ", "" + profile);*/

        if (social.equals("fb")) {
            Intent intent = new Intent(getApplicationContext(), SecondActivity.class);
            intent.putExtra("watson_res", profile.toString());
            intent.putExtra("Fb Feed", social_feed);
            startActivity(intent);
        } else {
            Intent intent = new Intent(getApplicationContext(), SecondActivity.class);
            intent.putExtra("watson_res", profile.toString());
            intent.putExtra("Twitter Feed", social_feed);
            startActivity(intent);
        }
    }
}

我收到一个特定Facebook帐户的无效JSON响应。 在该帐户中，我已将安全性设置为公开。 但是对于我的个人Facebook帐户，我得到{"data":[]} 。 即响应为null。
