Android check there is no fragment showing

Question

hello I am having an activity which have like 10 fragments I want to check when there is no fragment visible i.e after pressing back button I return to the main activity I want catch this back not back between fragments where no fragment visible I found a way here How to know if a Fragment is Visible? to check by tag name like here but I can't check for all 10 fragments by tag name any help?

if you found this - getSupportFragmentManager().getBackStackEntryCount() == 0 means not fragment is currently visible. — Sanwal Singh, Jan 03 '17 at 12:22
thanks a lot it works with getFragmentManager().getBackStackEntryCount() ==0 as I extends activity — Radwa, Jan 03 '17 at 12:30
For Kotlin, you can use supportFragmentManager.backStackEntryCount — portfoliobuilder, Jan 24 '20 at 23:45

If I understood your question right, by using

if (getSupportFragmentManager().findFragmentById(R.id.some_layout_id) != null)

you can find out if the layout with that id contains a fragment or not. This way you don't need to check for each fragment and you can check the fragment container directly. I hope it helps!
