Android: safe way to hide navigation spinner in ActionBar?
<p>I would like to show a spinner in my ActionBar, using <code>ActionBar.NAVIGATION_MODE_LIST</code>, but I would like it to hide/show based on some application context.  I have found that I can remove it from the ActionBar with <code>getActionBar().setNavigationMode(-1)</code>, however I don't know if this is a good idea.</p>

<p>Any feedback on if this is safe or if there is a safer alternative?</p>
