FileNotFoundException while reading RSS in Android

Question

I am trying to read an RSS feed. I have tried many links using the code below and succeeded, but when I try with that link above I get a FileNotFoundException. What could cause this, and how do I fix my code?

My logcat report:

02-29 15:20:44.183: W/System.err(2470): java.io.FileNotFoundException: http://screenrant.com/mobile/movie-news-feed.php

it will show in logcat 02-29 14:58:51.104: E/RSSParser(2212): java.io.FileNotFoundException: http://screenrant.com/mobile/movie-news-feed.php — Khan, Feb 29 '12 at 09:29
post the whole logcat of the error if you want people to be able to help you, not just one line. It should list all the effected lines, including the line in your code which is throwing the error — MikeIsrael, Feb 29 '12 at 09:34

try using HTtpConnection instead of URLConnection, as follows:

InputStream callWebErvice(String serviceURL){
        // http get client
            HttpClient client=new DefaultHttpClient();
            HttpGet getRequest=new HttpGet();

            try {
                // construct a URI object
                getRequest.setURI(new URI(serviceURL));
            } catch (URISyntaxException e) {
                Log.e("URISyntaxException", e.toString());
            }

            // buffer reader to read the response
            BufferedReader in=null;
            // the service response
            HttpResponse response=null;
            try {
                // execute the request
                response = client.execute(getRequest);
            } catch (ClientProtocolException e) {
                Log.e("ClientProtocolException", e.toString());
            } catch (IOException e) {
                Log.e("IO exception", e.toString());
            }
            if(response!=null)
                return response.getEntity().getContent();
            else
                return null;

    }

and change line xr.parse(new InputSource(url2.openStream()));

to

xr.parse(new InputSource(callWebErvice(url2)));
