I want to create a food order system at the restaurant using the android and WPF. so the waiter will use Android to transmit data to the Server(with ip) using wifi. and there is a wpf app in the server and which listening to a particular port.

for easier to test i am run both the android(in bluestack) and wpf app in same system.but unfortunately i did not get the data in wpf app.my code will attach here.

the main problem is am unable to find error whether the error is in android side or in wpf side.

android (client)

    //am already created the xml data and converted it to string(that code is not added here)
                        TransformerFactory factory = TransformerFactory.newInstance();
			Transformer transformer = factory.newTransformer();
			Properties outFormat = new Properties();
			outFormat.setProperty(OutputKeys.INDENT, "yes");
			outFormat.setProperty(OutputKeys.METHOD, "xml");
			outFormat.setProperty(OutputKeys.OMIT_XML_DECLARATION, "no");
			outFormat.setProperty(OutputKeys.VERSION, "1.0");
			outFormat.setProperty(OutputKeys.ENCODING, "UTF-8");
			transformer.setOutputProperties(outFormat);
			DOMSource domSource = new DOMSource(document.getDocumentElement());
			OutputStream output = new ByteArrayOutputStream();
			StreamResult result = new StreamResult(output);
			transformer.transform(domSource, result);
			xmlString = output.toString(); 
    //only small portion of the xml creation is added here
