title: Hidden features of Android development?
body: <p>I am surprised that there is no Android <em>Hidden Features</em> post yet in the <strong><a href="http://beerpla.net/2009/06/21/hidden-features-of-perl-php-javascript-c-c-c-java-ruby-python-and-others-collection-of-incredibly-useful-lists/" rel="nofollow noreferrer">Hidden Features series</a></strong> that I've been tracking for a while now.</p>
  
  <p>The Hidden Features series is great for people who are new to a certain language. It shows the ropes and certain valuable tricks, all in one place. I think it's a brilliant idea. Even experts sometimes find tricks they'd never heard about.</p>
  
  <p>I am starting Android development and I'd love to hear about its hidden features, tips, tricks, and pitfalls.</p>
  
  <p>So, here goes: what are some <strong>hidden features</strong> of <strong>Android</strong>?</p>
