title: Is AlarmManager suitable for writing clock widget?
body: <p>I want to write my own clock widget on Android. I am using my own icons to show the time (i.e., updating the ImageView(s) every second). I found a method using AlarmManager to handle the update and implemented it, but I have noticed that the app is using up my battery quickly, which I guess is because of the frequent update.</p>
  
  <p>Is there a more efficient method to do the update? </p>
  
  <p>Appreciate your help.</p>
  
  <p>Thanks &amp; Regards,
  Patrick</p>
