这是我的第一个android程序：helloword，我是在苹果机的模拟器上运行的，我想要连接到一个.NET

web服务器上，但是在connection.getOutputStream()发生exception，我可以从模拟器进到那个位置
有什么建议吗？   URL url = new URL("http://192.168.3.47/service.asmx");

    HttpURLConnection connection = (HttpURLConnection)url.openConnection();

    connection.setRequestMethod(&quotOST");

    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");
