Android：嘗試HttpURLConnection.getOutputStream時拋出SocketException（）

這是我第一個android程序，它是一個修改後的hello世界。我在MAC上的模擬器上運行它。我嘗試與.NET Web服務進行通信，但它在處發生了異常。我可以從模擬器訪問網站。任何幫助表示讚賞:)Android：嘗試HttpURLConnection.getOutputStream時拋出SocketException（）


    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");

嘗試添加了「互聯網」權限上的AndroidManifest.xml：

<uses-permission android:name="android.permission.INTERNET" />
