title: What is the android relevant of CADisplayLink(iOS) or CompositionTarget(WP)
body: <p>I need to update my animations per frame, on iOS I have <a href="http://developer.apple.com/library/ios/#documentation/QuartzCore/Reference/CADisplayLink_ClassRef/Reference/Reference.html" rel="noreferrer"><code>CADisplayLink</code></a>, on WinPhone I have <a href="http://msdn.microsoft.com/en-us/library/windows/apps/windows.ui.xaml.media.compositiontarget.rendering" rel="noreferrer"><code>CompositionTarget</code></a>, but how do I do that on Android?</p>
  
  <p>Currently I'm using a <code>Timer</code> alongside a <code>Handler</code>, but I believe there is a way to sync the callback with the refresh rate.</p>
