title: Android re-enable a disabled App upon installation of update
body: <p>Im currently disabling an application via
      setApplicationEnabledSetting(String, int, int)</p>
  
  <p>The application is actually disabling itself.
  I would expect upon re-installation of the app, the app would re-enable itself, however this isnt the case.</p>
  
  <p>Is there a particular setting required in the manifest to make this work.
  (Ive tried setting enabled=true)</p>
  
  <p>Thanks</p>
  
  <p>Im currently disabling all components apart from a broadcast receiver and am trying to catch the installation process to re-enable all the other components again. Which is nasty to say the least</p>
