Facebook - 获取有关共享帖子的信息

Question

我从我的小组收到所有帖子，我想在我的网站上发布。 当我从粉丝页面分享一些帖子时 - 我可以获得有关此帖子的所有信息：

import android.support.v7.app.ActionBarActivity;

public class MainActivity extends ActivityBarActivity {

      ActionBar mActionBar = getSupportActionBar();
      mActionBar.setDisplayOptions(ActionBar.DISPLAY_HOME_AS_UP | ActionBar.DISPLAY_SHOW_CUSTOM | ActionBar.DISPLAY_SHOW_HOME);
  }

这是这篇文章的屏幕：

问题是当我分享用户的帖子时。我无法获得有关这些帖子的任何信息：

为什么我无法获得有关作者，共享post_id等的信息？这是我的代码：

array(2) {
  ["data"]=>
  array(12) {
    [0]=>
    array(6) {
      ["from"]=>
      array(2) {

        string(20) "Franciszek Bonaparte"
