Hi @shreelakshmijoshi! Just run the demo DrawableAnimations on any android phone or emulator, follow the steps I provided:

start the app DrawableAnimations -> click AnimatedVectorDrawableCompat -> click START -> back press before the animation is done,

then check the logcat to find the stacktrace, you can set some breakpoints to help you understand how it works.

The animated fragment is set to null after the animation is completed. When we press the back button , the view gets destroyed but the animated fragment which is bound to the view is still running. We should also destroy the object associated with the view when back button is pressed.
That's why OnBackPressedCallback function is added which implements the operation of the stop button

 override fun onAttach(context: Context){
       super.onAttach(context)
       val callback: OnBackPressedCallback =object:OnBackPressedCallback(
       true
       ){
           override fun handleOnBackPressed(){
               binding.stop.performClick()
               activity?.supportFragmentManager?.popBackStack()
           }
       }
       requireActivity().onBackPressedDispatcher.addCallback(
           this,
           callback
       )
   }
