title: Animation is too slow
body: <p>I am working on a game for the Android platform. The layout consist elements which should move without stopping from top to bottom. I decided to use an <code>Handler</code> and I set <code>handler.postDelayed(this, 10)</code>.<br>
  the animation "step" is <code>5px</code> (It's actually not <code>px</code> but doesn't matter for the discussion).  </p>
  
  <p>The thing is, the animation frequently twitching and isn't smooth. With every call of the handler, I make some simple checks and use <code>setX(), setY()</code> to change the elements position.  </p>
  
  <p>What should I do to make the animation smooth? Should I tweak the numbers mention above? Also, I've understood the method <code>setWillNotDraw(boolean b)</code> might be useful - How to use it wisely?</p>
  
  <p>I'd be glad if you could guide me what should I do (Kind of "Do and Don't").</p>
  
  <p>Thank you!</p>
