title: Android application update - how to?
body: <p>What is the best way to let my users perform an application update?</p>
  
  <p>Is there any way to force device reboot after the update? I'm asking this because my application registers some behavior on boot.</p>
  
  <p>Please note, the application would not be published in the Market. </p>
  
  <p>Update:</p>
  
  <p>My app will be preinstalled on a set of ~100 handsets.
  Should I periodically call a webservice that will inform the device about upgrade available, and then, redirect to an .apk file within a webkit view?</p>
