title: Android: App shortcut has to be recreated after update
body: <p>A weird thing is happening:
  I've published an update to google play. When users download the update the existing home screen shortcut disappears and the have to recreate it or on other devices, the shortcut stays on the homescreen, but when they press it, it says the refering app isn't there and then they have to delete that shortcut and recreate it.</p>
  
  <p>Does anyone know why this is happening?</p>
