title: What happens to the Activity lifecycle after an app update?
body: <p>Suppose this scenario. You have an app where you fill a form in one activity. The activity uses <code>onRestoreInstanceState</code> and <code>onSaveInstanceState</code> to save the responses of the form. If a user is filling the form with app version 1, and then the PlayStore automatically updates and installs the app to version 2 before he finishes, what version was the form completed on?</p>
  
  <p>Same question but supposing the user forces the update?</p>
  
  <p>Thanks</p>
