Starting with API level 21, 69[Android includes support for material design][1] apps. 70 71This sample demonstrates the use of `Material Design` animation interpolators 72and 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 74can also define the duration of the animation. 75 76[1]: https://developer.android.com/training/material/index.html 77[2]: https://developer.android.com/guide/topics/graphics/prop-animation.html#object-animator 78 79]]> 80 </intro> 81 </metadata> 82 83 84 85</sample> 86
