title: onSaveInstanceState () and onRestoreInstanceState ()
body: <p>I'm trying to save and restore the state of an <code>Activity</code> using the methods <code>onSaveInstanceState()</code> and <code>onRestoreInstanceState()</code>.</p>
  
  <p>The problem is that it never enters the <code>onRestoreInstanceState()</code> method. Can anyone explain to me why this is?</p>
