Use this 

DefaultHttpClient httpClient = new DefaultHttpClient();
HttpGet httpGet = new HttpGet("http://www.someplace.com");
ResponseHandler<String> resHandler = new BasicResponseHandler();
String page = httpClient.execute(httpGet, resHandler);

This can be used to grab the whole webpage as a string of html, i.e., "<html>...</html>"

Note You need to declare the following 'uses-permission' in the android manifest xml file... answer by @Squonk here

You can do the HTML parsing but it is not at all recommended instead ask the website owners to provide web services then you can parse that information.

You can use jsoup to parse any kind of web page. Here you can find the jsoup library and full source code.

Here is an example: http://desicoding.blogspot.com/2011/03/how-to-parse-html-in-java-jsoup.html

To install in Eclipse:

  1. Right Click on project
  2. BuildPath
  3. Add External Archives
  4. select the .jar file

You can parse according to tag/parent/child very comfortably
