title: Android update activity UI from service
body: <p>I have a service which is checking for new task all the time. If there is new task, I want to refresh the activity UI to show that info. 
  I did find <a href="https://github.com/commonsguy/cw-andtutorials/tree/master/18-LocalService/">https://github.com/commonsguy/cw-andtutorials/tree/master/18-LocalService/</a> this example. Is that a good approch ? Any other examples?</p>
  
  <p>Thanks.</p>
