     67 Material design is a comprehensive guide for visual, motion, and interaction
     68 design across platforms and devices. Starting with API level 21,
     69 [Android includes support for material design][1] apps.
     70 
     71 This sample demonstrates the use of `Material Design` animation interpolators
     72 and path animations. It uses an [ObjectAnimator][2] to animate two view properties,
     73 `Scale_X` and `Scale_Y`. Users can pick from a set of interpolator options. They
     74 can also define the duration of the animation.
