title: setShowsAsAction not working below API 11
body: <p>This is the code I used to remove a <code>MenuItem</code>:</p>
  
  <pre><code>af.setShowAsAction(MenuItem.SHOW_AS_ACTION_NEVER);
  </code></pre>
  
  <p>However, <code>setShowsAsAction</code> requires minimum API 11 so it crashes on GingerBread. I can use <code>af.setVisible(false);</code> to get the code to work on GingerBread. What are the differences between the two? Is it the same thing?</p>
