Android應用程序中的UnknownHostException警告

我正在開發一個使用Web服務和調用API發送請求並獲取響應的Android應用程序。Android應用程序中的UnknownHostException警告

我的申請被罰款前工作，但現在當我開始我的應用程序了，並嘗試登錄（應用程序的第一頁。）這說明下面的警告和例外

我的應用程序代碼行：

SoapObject request = new SoapObject(NAMESPACE, METHOD_NAME); 
     request.addProperty("requestXml", envelope1); 
     SoapSerializationEnvelope envelope = new SoapSerializationEnvelope(
       SoapEnvelope.VER11); 
     envelope.setOutputSoapObject(request); 
     HttpTransportSE androidHttpTransport = new HttpTransportSE(URL); 
     Object response = null; 
     try { 
      androidHttpTransport.call(SOAP_ACTION, envelope); 
      response = envelope.getResponse(); 
      authenticationLoginResponse = response.toString(); 
     } catch (Exception e) { 
      e.printStackTrace(); 
     }

我收到以下行的警告：

androidHttpTransport.call（SOAP_ACTION，envelope）;

完善的報警日誌：

任何機構可以說明爲什麼這個錯誤是蓄勢而這個項目很好，前幾天運行？

你在使用模擬器嗎？如果然後卸載應用程序並重新啓動您的模擬器.. – hacker
