Векторная анимация в приложениях android (Animated Vector Drawable)

Как использовать векторную анимацию (Animated Vector Drawable) в андроид-приложениях. Как загрузть в приложение android свою векторную картинку и как анимировать векторные изображения.

На прошлом уроке по дизайну андроид-приложений мы говорили об использовании векторной графики и научились создавать векторные ресурсы в Андроид Студио.

На этом уроке загрузим в приложение свою векторную картинку и научимся анимировать векторные изображения. Исходный код под видео.

При анимации вылетает клас каст ексепшин, но почему?
switch_circle.xml

AppCompatImageButton switchCircle = (AppCompatImageButton) view.findViewById(R.id.switchButtonCircle); Drawable drawable = switchCircle.getDrawable(); ((Animatable) drawable).start();
switch_circle_animated_vector.xml

filling.xml
