致命異常：Android的JSON響應中的AsyncTask＃3

-3

我得到了下一個excepcition，但我不知道爲什麼。我tryiing得到一個JSON階躍響應從Django的服務器對象（Django的服務器工作percetly），但我得到了一個錯誤：致命異常：Android的JSON響應中的AsyncTask＃3

    05-13 19:57:29.069: E/AndroidRuntime(8845):  at com.example.webservicestemperatura.MainActivity$sampleService.doInBackground(MainActivity

我的代碼是下一個：

class sampleService extends AsyncTask<Boolean, Boolean, Boolean> { 

     @Override 
     protected Boolean doInBackground(Boolean... params) { 
      HttpClient httpClient = new DefaultHttpClient(); 
      HttpGet del = new HttpGet("192.168.1.68:8000/c_f/4.0"); 
      del.setHeader("content-type", "application/json"); 
      try { 
       HttpResponse resp = httpClient.execute(del); 
       String respStr = EntityUtils.toString(resp.getEntity()); 
       JSONObject respJSON = new JSONObject(respStr); 
       String far = respJSON.getString ("far"); //Check your type data to return in your web service. 


       System.out.println("HOLAAAAAAAAAAAAAAAAAAAAAA" + far); 
       Log.d("Service", far); 
      } catch(Exception ex) { 
       Log.e("Service","Error!", ex); 
      } 
      return null; 
     }

如果我得到http：//它說「連接被拒絕」：當我在Web瀏覽器中使用它時，它完美地工作而且我得到了JSON響應。但後來我得到了下一個錯誤：

您的URI無效，因爲它缺少協議。如果您在前面附加http://，它應該可以正常工作

爲了響應您的更新，您應該學會正確地閱讀LogCat。

說Caused by:的行是尋找的行，因爲他們通常會告訴你問題的根源。在這種情況下，the exception you posted的快速谷歌帶來了許多堆棧溢出的答案，可以解決你的問題。

如果我使用以http：//它說：連接被拒絕：在瀏覽器中它完美的作品和我得到的JSON回答， –

異常的其餘部分是什麼？連接可能被拒絕的原因有很多。更新OP – panini

我已經更新並且您可以看到錯誤。請幫幫我 –

您的網址是壞的形成，需要defin「HTTTP：//」
