public class MainActivity extends Activity {

    @Override
    protected void onCreate(Bundle savedInstanceState)
    {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        try {
            executeHttpGet();
        } catch (Exception e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        }

    }
        //Method for http request

        public void executeHttpGet() throws Exception {

            BufferedReader in = null;

            try {

                System.out.println("ndkjsdak");
                HttpClient client = new DefaultHttpClient();
                HttpGet request = new HttpGet();

                HttpProtocolParams.setUseExpectContinue(client.getParams(), false);


                request.setURI(new URI("http://www.irock109.com/streams/irock109-128mp3.asx"));

                //HttpResponse response = client.execute(request);

                HttpResponse response = null;

                boolean RetryConnection = true;
                int retrycount = 0;

                    {
                        System.out.println("caught");
                        retrycount += 1;
                    }
                }

                in = new BufferedReader
                (new InputStreamReader(response.getEntity().getContent()));

                }
                in.close();
                String page=sb.toString();

                XmlPullParserFactory factory = XmlPullParserFactory.newInstance();
                 factory.setNamespaceAware(true);
                 XmlPullParser xpp = factory.newPullParser();

                 xpp.setInput( new StringReader (page) );
                 int eventType = xpp.getEventType();
                 while (eventType != XmlPullParser.END_DOCUMENT)

                  {
                      System.out.println("Text "+xpp.getText());
                  }

                 System.out.println("End document");
            }
            finally 
            {
                if (in != null) 
                {
                    try
                    {
                        in.close();
                    } 
                    catch (IOException e)
                        {
                        e.printStackTrace();
                    }
                }
            }
    }
}

How can I get the href from ref?

Try this

try {
            XmlPullParserFactory factory = XmlPullParserFactory.newInstance();
            factory.setNamespaceAware(true);
            XmlPullParser xpp = factory.newPullParser();

            xpp.setInput(new StringReader(xmlData));
            int eventType = xpp.getEventType();
            while (eventType != XmlPullParser.END_DOCUMENT) {
                if (eventType == XmlPullParser.START_DOCUMENT) {
                    System.out.println("Start document");
                } else if (eventType == XmlPullParser.START_TAG) {
                    if(xpp.getName().equalsIgnoreCase("REF"))
                    {
                        System.out.println("REF Text = " + xpp.getAttributeValue(0));
                    }
                    System.out.println("Start tag " + xpp.getName());
                } else if (eventType == XmlPullParser.END_TAG) {
                    System.out.println("End tag " + xpp.getName());
                } else if (eventType == XmlPullParser.TEXT) {
                    System.out.println("Text  = " + xpp.getText());

                }
                eventType = xpp.next();
            }
            System.out.println("End document");
        } catch (Exception e) {
        }
