Android training class for adding Animations

Android developers has published new training class for Adding Animations in Android app, which quickly gets you up to speed on implementing common animations and transitions in your app with the new-ish android.animation APIs.
It covers basics like crossfades (dissolves), screen slides with ViewPager, card flips, zooms (although nothing on API 16 ActivityOptions yet), and automatic layout change animations.
