removing fragment with popBackStack();

Question

I have a few fragments in one activity. In Main Activity I implemented popBackStack(); in onBackPressed();

So that, you can always go back to previous fragment clicking back button. But popBackStack(); doesn't remove the fragment I just left.

How to achieve removing current fragment each time, we click back button?

How do you load the fragments? Do you call addToBackStack()? If so you don't need to implement onBackPressed() as Android does this for you. — Code-Apprentice, Sep 24 '16 at 14:02
As told by code-apprentice, if you properly add fragment during fragment transaction. Then you need not pop out the fragment specifically. popbackStack is generally used for buttons and clicks other than back button — Mohammed Atif, Sep 24 '16 at 14:10

 public void removeFragmentbyTag(String myFrag){

 FragmentManager manager = getActivity().getSupportFragmentManager();
 FragmentTransaction trans = manager.beginTransaction();
 trans.remove(myFrag);
 trans.commit();
 manager.popBackStack();
}

hope this bit of code help you.

how do I get a fragment tag in MainActivity with onBackPressed function? – Tomek Sep 24 '16 at 14:48
when you add fragments to main activity add fragment tag to each fragment – Vij Sep 24 '16 at 14:55
getFragmentManager().beginTransaction().add(R.id.fragment_container, fragmentToBeAdded, tag).commit(); where tag is String – Vij Sep 24 '16 at 14:55

Thanks. You have saved my day. – Adizbek Ergashev Feb 24 '18 at 12:41
You can also use `getFragmentManager().beginTransaction().remove(getFragmentManager().findFragmentById(R.id.fragmentcontainer)).commit();` – uzaysan Apr 05 '19 at 08:59
