title: TimerTask vs AlaramManager, Which one should I use?
body: <p>I am working on an application which triggers an action (say toast message) every 10 minutes after the screen is ON and stops the action after the screen is OFF.
  I have used TimerTask for this purpose.
  Shall I start using AlaramManager instead of TimerTask or shall I keep using TimerTask ?
  I know the difference between the two but can't figure out which to use.</p>
