refresh the fragment when getting back from an activity or pressing back

I was trying to refresh the fragment when pressing back from an activity, I tried using onResume() and onStop() and it worked but... another issue comes. using onResume() and onStop() inside the fragment is making the fragment refresh too many times that the app is crashing and I really don't know what I am doing wrong, if you can please help me with this issue

my onResume() function

   override fun onResume() {
        super.onResume()
        //shoudRefreshOnResume is a global var
        if (shouldRefreshOnResume) {
            val ft: FragmentTransaction = parentFragmentManager.beginTransaction()
            ft.detach(this).attach(this).commit()
        }
    }

my onStop() function

override fun onStop() {
    super.onStop()
    shouldRefreshOnResume = true
}

my onCreateView() function

override fun onCreateView(
    inflater: LayoutInflater,
    container: ViewGroup?,
    savedInstanceState: Bundle?
): View? {
    val root = inflater.inflate(R.layout.fragment_home, container, false)
    val foodButton = root.findViewById<Button>(R.id.mainFoodButton)
    val recentlyViewed = root.findViewById<LinearLayout>(R.id.recently_viewedView)

    foodButton.setOnClickListener {
        val intent = Intent(activity, CategoriesActivity::class.java)
        startActivity(intent)
    }
    //createRecentlyViewedButton() is a function
    createRecentlyViewedButton(recentlyViewed)

    return root
}

I fixed the issue by replacing onStop() function to onPause() since the activity is not getting destroyed and it no longer loop the createRecentlyViewedButton() function hope this help somebody

here are the changes I made though

override fun onPause() {
    super.onPause()
    shouldRefreshOnResume = true
}

and

   override fun onResume() {
        super.onResume()
        //shoudRefreshOnResume is a global var
        if (shouldRefreshOnResume) {
        val recentlyViewed = activity?.findViewById<LinearLayout>(R.id.recently_viewedView)
        createRecentlyViewedButton(recentlyViewed!!)
        }
    }
