Why are ViewPropertyAnimatorRT missing in API 29?

Question

I want to use this class to render the animation in the word thread,

But now I can't find this class, who can tell me why this class was deleted？

Answer 1

question why it was removed should be answered by someone from Android team. probably they just refactored some internal animation utils due to new possibilities...

you can always copy-paste this class source and paste into your project (with different name just in case), you probably should find workaround for FallbackLUTInterpolator usage (or just remove related items, supplying different Interpolator in this place, eg. linear)
