title: Where is the bundle of onSaveInstanceState saved?
body: <p>I would like to know where the bundle "outState" of the method <a href="http://developer.android.com/reference/android/app/Activity.html#onSaveInstanceState%28android.os.Bundle%29">onSaveInstanceState(Bundle outState)</a> is stored. </p>
  
  <p>Is it stored in memory or in the device storage?</p>
  
  <p>I am concerned about the security of the data which is stored in the bundle.</p>
