body: <p>How to create an android app that can notify user immediately if something on a website is updated.
  Suppose I have a blogger blog like <a href="http://abcd.blogspot.com" rel="nofollow">http://abcd.blogspot.com</a> So what I want is that whenever I post a new topic on my blog that topic notification should be pushed on to every android device that has my app installed. Please explain in detail if possible And I am not able to use PHP because its a blogger blog.</p>
