问题:

I have the following site http://www.freewebservicesx.com/GoldSpotPrice.aspx which provides a webservice api. As i am extremely new to soap and rest i have absolutely no clue about how to call this service and use it in android. Could someone please tell me how to do it.

You can make HTTP requests using either HttpURLConnection or HttpClient. Example of using HttpClient for a RESTful web service:

HttpClient httpClient = new DefaultHttpClient();
HttpGet httpGet = new HttpGet("http://www.mywebsite.com/webservice");
HttpResponse response = httpClient.execute(httpGet);
StatusLine statusLine = response.getStatusLine();
if (statusLine.getStatusCode() == HttpStatus.SC_OK) {
    HttpEntity entity = response.getEntity();
    ByteArrayOutputStream out = new ByteArrayOutputStream();
    entity.writeTo(out);
    out.close();
    String responseStr = out.toString();
    // process response
} else {
    // handle bad response
}

Otherwise, if you're working with a SOAP web service, I would recommend using ksoap2
