When the screen orientation changes the system will, by default, destroy the current activity and create a new one while preserving its state
<p>I can not able to understand this sentence in android documention. Since it is saying </p>

<blockquote>
  <p>When the screen orientation changes the system will, by default, <strong>destroy the current activity.</strong></p>
</blockquote>

<p>and it also saying </p>

<blockquote>
  <p>create a new one while <strong>preserving its state.</strong></p>
</blockquote>

<p>but actully it is contrary. How could it be? Can anybody explan to me.</p>
