的Facebook SDK圖形響應爲空

我想用我的應用程序來獲取好友列表，我從Facebook SDK寫了下面的代碼：的Facebook SDK圖形響應爲空

FacebookSdk.sdkInitialize(getApplicationContext()); 
     new GraphRequest(
    AccessToken.getCurrentAccessToken(), 
    "me/friends?fields=name,email", 
    null, 
    HttpMethod.GET, 
    new GraphRequest.Callback() { 
     public void onCompleted(GraphResponse response) { 
      /* handle the result */ 
      Log.d("[email protected]", "graph response " + response.getJSONObject()); 
     } 
    } 
).executeAsync();

這裏是我的logcat：
