title: Accessing UI thread handler from a service
body: <p>I am trying some thing new on Android for which I need to access the handler of the UI thread.</p>
  
  <p>I know the following:</p>
  
  <ol>
  <li>The UI thread has its own handler
  and looper </li>
  <li>Any message will be put
  into the message queue of the UI
  thread </li>
  <li>The looper picks up the event
  and passed it to the handler </li>
  <li>The handler handles the message and
  sends the specfic event to the UI</li>
  </ol>
  
  <p>I want to have my service which has to get the UI thread handler and put a message into this handler.
  So that this message will be processed and will be issued to the UI.
  Here the service will be a normal service which will be started by some application.</p>
  
  <p>I would like to know if this is possible.
  If so please suggest some code snippets, so that I can try it.</p>
  
  <p>Regards
  Girish</p>
