Have you ever made a custom view using only canvas? Now have you ever tried to animate it? If you found that problematic this talk will help you grasp basic stuff about animating custom drawn views.
Our agency's motto is "Design Driven Development" which means that our apps should be sexy, smooth, beautiful and animated. With lots of custom views drawn only by canvas, problems arise when those views should also be animated. Smoothly transforming a custom drawn chart from one curve to another for example. This talk should help you to dig in a bit into that area, to show you how to animate without the animator and interpolate without the interpolator.
