在Android应用程序中从fql查询中提取信息

我正尝试在Android中的不同字符串中存储由我上传的视频的视频ID和其他信息。现在我已经创建了一个fql查询来获取视频细节。我使用JSON解析提取喜欢这个 -在Android应用程序中从fql查询中提取信息

String fqlQuery = "SELECT vid, owner, title, description,updated_time, created_time FROM video WHERE owner=me()"; 
        Bundle params = new Bundle(); 
        params.putString("q", fqlQuery); 
        Session session = Session.getActiveSession(); 
        Request request = new Request(session,"/fql",params,HttpMethod.GET,new Request.Callback() 
        { 
         public void onCompleted(Response response) 
         { 
          try 
          { 
           JSONObject json = Util.parseJson(response.toString()); 
           JSONArray data = json.getJSONArray("data"); 
           for (int i = 0, size = data.length(); i < size; i++) 
           { 
            JSONObject getVideo = data.getJSONObject(i); 
            userNameView.setText(getVideo.getString("vid")); 

           } 

          } 
          catch(Exception e){userNameView.setText(e.toString());} 
         }     
        }); 
        Request.executeBatchAsync(request);     
       } 
      });

的值，但它扔我exception-

org.json.JSONException：未终止的对象在 {响应特性25：responseCode：200 ，graphObject：GraphObject {graphObjectClass = GraphObject，状态= { “数据”：[{ “所有者”：...}]}}}

它的我第一次与Android，Facebook的SDK也使用JSON解析，所以我会真的伟大的任何帮助提供。谢谢。

最后，我能够在这里得到问题，response.toString（）没有给出纯JSONObject字符串，所以我不得不从response.toString（）的输出中取出子字符串，使它看起来像一个JSONObject串。

 int indexex=nthOccurrence(response.getGraphObject().toString(),'{',1); 
     int index=response.getGraphObject().toString().length()-1; 
     String edit=response.getGraphObject().toString().substring(indexex, index); 
     JSONObject json = Util.parseJson(edit); 
     JSONArray data = json.getJSONArray("data"); 
     for (int i = 0, size = data.length(); i < size; i++) 
     { 
      JSONObject getVideo = data.getJSONObject(i); 
      userNameView.setText(getVideo.getString("vid"));    
     }

我想这可能不是正确的做法，但这是我能想出的唯一方法。如果有任何人知道更好的方式做到这一点，请回复。谢谢
