無法通過Android應用程序訪問Facebook朋友

我通過我的android應用程序訪問圖API時遇到問題，該應用程序檢索用戶的朋友爲JSONObject，提取他們的名字並將其顯示在屏幕上。它應該是一個簡單而直接的任務，但顯然它不是。當我在Android Nexus I上運行我的應用程序時，我登錄到Facebook，然後詢問我單擊「允許」按鈕授予權限，然後重定向到空白頁面。我期望看到我的朋友的名字，但它不會發生。有人能幫助我嗎？無法通過Android應用程序訪問Facebook朋友

當你調試，它實際上擊中了好友請求偵聽器的onComplete回調方法？ –

嘿，如果我的回答有助於解決問題，您應該將其標記爲已接受的答案（點擊答案旁邊的複選標記） –

我想我可能已經發現了這個問題..根據關於onComplet的文檔;

 /** 
    * Called when a request completes with the given response. 
    * 
    * Executed by a background thread: do not update the UI in this method. 
    */

而且你要更新你的UI，所以addViews不着手在UI線程上體現。您應該建立在你的活性的方法，你可以從使用的onComplete調用runOnUIThread ..喜歡的東西這個;

runOnUiThread(new Runnable() { 
      public void run() { 
       inserFacebookNames(facebookContactNames); 
      } 
     });

讓我知道如果這實際上修復它。我很好奇，如果是這樣的原因..
