從json檢索給出了錯誤android

我收到以下錯誤。

服務器上的日誌

E/log_tag(1948): connection success [sendernumber=9040307070] 
E/log_tag(1948): result ?9545357470[{"TaskId":"1"},{"TaskId":"2"}] 
E/log_tag(1948): Error parsing data org.json.JSONException: Value 9040307070 of type java.lang.Long cannot be converted to JSONArray

JSON代碼

 String result = null;

      httppost.setEntity(new UrlEncodedFormEntity(nameValuePairs)); 
      HttpResponse response = httpclient.execute(httppost); 

      HttpEntity entity = response.getEntity();

看來你沒有得到響應json數組正確！請檢查併發布你正在收到什麼回覆 –

我只得到很多錯誤日誌 – user3256145

你得到的迴應9545357470 [{「TaskId」：「1」}，{「TaskId」：「2」}]爲什麼數據9545357470附有你的迴應？你是否爲此進行過調查？ –

如果你想將它WO rk，用JSONArray jArray = new JSONArray(result.substring(result.indexOf("[")));代替JSONArray jArray = new JSONArray(result);

然而，你的web服務似乎有些問題。它返回9545357470[{"TaskId":"1"},{"TaskId":"2"}]，那真的應該是[{"TaskId":"1"},{"TaskId":"2"}]。所以我不確定當你試圖創建你的json數組來發送它作爲響應時發生了什麼，但最好的解決方案是解決這個問題，而不是你在這裏的代碼。
