title: PostDelayed or Thread with thread.sleep()
body: <p>If I need to update UI components ( like textview) every second as long as the activity is visible.  Would you recommend creating a thread (with thread.sleep) which does postOnUi call OR do I use handler with postDelayed?</p>
  
  <p>I am not sure which would be more efficient provided that I have multiple textviews</p>
  
  <p>Thanks?</p>
