title: Update text of card in Google Glass using GDK?
body: <p>I'm interested in changing the text of a card based on some event. Is it possible to change the text of card without calling <code>setContentView()</code> on the Activity?</p>
  
  <p>Once the card has been converted into view and set using <code>setContentView()</code>, I haven't found a way to change its contents without calling 'setContentView()' again.</p>
