Android : SocketException HttpURLConnection.getOutputStream()을 시도 할 때 throw됩니다.

Question

이것은 내 첫 안드로이드 프로그램으로, 수정 된 안녕 세상입니다. MAC의 에뮬레이터에서 실행하고 있습니다. .NET 웹 서비스와 통신을 시도하지만 에 예외가 있습니다. 에뮬레이터에서 사이트에 액세스 할 수 있습니다. 어떤 도움에 감사드립니다 :)

    URL url = new URL("http://192.168.3.47/service.asmx"); 
    HttpURLConnection connection = (HttpURLConnection)url.openConnection(); 
    connection.setRequestMethod("POST"); 
    connection.setRequestProperty("Content-Type", 
    "application/soap+xml; charset=utf-8"); 

    connection.setUseCaches(false); 
    connection.setDoInput(true); 
    connection.setDoOutput(true); 

    String soapRequest = String.format(getText(R.string.ws_listemain_ds_new).toString(), city, keyword); 
    connection.setRequestProperty("Content-Length", Integer.toString(soapRequest.getBytes("UTF-8").length)); 
    //Send request 
    OutputStreamWriter owr = new OutputStreamWriter(connection.getOutputStream(), "UTF-8");
