title: Ripple Effect on Android pre-L
body: <p>I'm searching for a lib that is able to simulate the new shiny ripple effect when tapping on a button introduced 28th Android L / API 21.
  There are already a few apps that use it, like TV Series and Pushtime, for example.. But the libraries I found both do something different (I'm talking about Ripple by traex and Ripple Background).</p>
  
  <p>Thanks a lot guys! See you..</p>
