title: How to update an Android widget every second ... to draw a clock with a seconds hand?
body: <p>I have been reading much from various sources on ways to update a widget that is using ImageView Canvas and Draw method to display a clock with a seconds hand.</p>
  
  <p>It must be updated every second. What is the most efficient way to do this? Use a <code>Service</code>, the Alarm Manager, Handlers?</p>
  
  <p>It can be done, e.g., the Android app <a href="http://www.androidzoom.com/android_applications/tools/arc-clock-widget_jimn.html" rel="nofollow noreferrer">"Arc Clock Widget"</a>.</p>
  
  <p>Anyone with any ideas?</p>
  
  <p>Thanks,
  Tom</p>
