title: Time/Date change listener
body: <p>I want to make a time or date listener which for example invoke an activity every day at 9 AM. I am not sure what is the best way to do that? I know I can use Alarm Manager, but I don't know how to make it repetitive? </p>
  
  <p>Does anyone know? Thank you very much in advance.</p>
