title: TimePicker from android examples not working
body: <p>I'm trying to make work this example from  <a href="http://developer.android.com/resources/tutorials/views/hello-timepicker.html" rel="nofollow">http://developer.android.com/resources/tutorials/views/hello-timepicker.html</a> ,
  no errors while compiling - but when I press button - nothing happens. Complete silent. Why? Btw - I tried to put Log.d() in button click event and it works, but still no popup with timepicker.</p>
  
  <p>Main.xml used "As is" from example</p>
