title: Android Material Design View State changes vs Elevation
body: <p>I'm trying to implement Material Design in my apps but I can't understand what is the difference to implement a shadow with <code>StateListAnimator</code> or assign an elevation to the views.</p>
  
  <p>Below is the links about what im talking about:</p>
  
  <p><a href="http://developer.android.com/training/material/animations.html#ViewState" rel="nofollow noreferrer">StateListAnimator</a><br>
  <a href="http://developer.android.com/training/material/shadows-clipping.html#Elevation" rel="nofollow noreferrer">Elevation</a></p>
  
  <p>What I'm seeing is that both can do the same thing, so why did they implement both in v5.0?</p>
