title: Android components showcase / visual guide
body: <p>As a new developer with Android I miss a component showcase or a visual guide like <a href="http://download.oracle.com/javase/tutorial/ui/features/compWin.html" rel="noreferrer">that for swing</a> in the documentation.
  There is one in someplace?
  Normally what I do is use google images with the component name but a visual guide will be nicer.</p>
