How to keep ObjectAnimator on screen rotation?

Question

Android

Hello.
Faced difficulty, you need to save the value of the animator when the screen is rotated, but I don’t understand and can’t figure out how to do it (except for crutches)

ObjectAnimator anim = ObjectAnimator.ofInt(progressBar, "progress", 800, 0);
        anim.setDuration(8000);
        anim.start();

When turning, everything starts all over again . There is also a timer in
AsyncTask, I save it with no problems, I can’t figure out how to save the value of the progress bar. The idea for each iteration is to do the following:

timer....
run(){
iter++;// проверить сколько раз сработал таймер
ObjectAnimator anim = ObjectAnimator.ofInt(progressBar, "progress", iter*100

But this is some kind of crutch, tell me how to be
