Dynamic and persistent data
<p>It is stated in documentation that <code>onSaveInstanceState(Bundle)</code> is called before placing the activity in such a background state, allowing you to save away any <strong>dynamic</strong> instance state in your activity into the given Bundle. Note that it is important to save <strong>persistent</strong> data in <code>onPause()</code> instead of <code>onSaveInstanceState(Bundle)</code>.</p>

<p>What is the best way to distinguish dynamic data with persistent?</p>
