we need entire code fragment to help you identify what causes bug just this info isn't enough — Bacho Kurtanidze, Mar 27 '20 at 18:20

I use another way to create fragment.

On activity :

String name = "checkout";
Bundle bundle = new Bundle();
bundle.putString("name", name);

MyFragment.newInstance(bundle)

On Fragment :

fun newInstance(bundle: Bundle?): MyFragment? {
        if (bundle == null)
            return null

        val fragment = MyFragment()
        fragment.mUserId = bundle.getString("name")
        return fragment
    }

Tell me if it's good
