Android getting text from a URL always NULL

Question

I'd like to send an http request and get a string back from that request.

I am currently using this code, but no matter what my URL is, I always get null. What's the issue?

try { // Create a URL for the desired page URL url = new URL("http://hostname:80/index.html");

// Read all the text returned by the server
BufferedReader in = new BufferedReader(new InputStreamReader(url.openStream()));
String str;
while ((str = in.readLine()) != null) {
    // str is one line of text; readLine() strips the newline character(s)
}
in.close(); } catch (MalformedURLException e) { } catch (IOException e) { }

                String URL = "http://hostname:80/index.html"
                String XML = stringWriter.toString();
                // System.out.println(XML);

                se = new StringEntity(XML, "UTF-8");
                se.setContentType("text/xml;charset=UTF-8");
                HttpPost httppost = new HttpPost(URL);
                httppost.setEntity(se);

                HttpClient httpclient = new DefaultHttpClient();
                response = httpclient.execute(httppost);

                HttpEntity entity = response.getEntity();

try use from this code
