title: Stopping a background service from notification
body: <p>I have a background service in which I want to show a notification which allows the user to stop it.</p>
  
  <p>In the android SDK docs it says an activity is used to normally launch an Activity. So I am wondering if I need to create an activity to stop the service or can I directly stop the service when user selects the notification,</p>
  
  <p>So how would the intend call back the service to stop it..</p>
  
  <p>Thanks, </p>
