android fragment popBackStack without POP_BACK_STACK_INCLUSIVE

Question

I have a deep, nested, fragment application. When I use the below code all works.

fragmentManager.popBackStack("root", FragmentManager.POP_BACK_STACK_INCLUSIVE);

However I want to keep the root fragment so I call

fragmentManager.popBackStack("root", 0);

But it doens't work, the Stack is the same. I'm sure that "root" is present because when I use the first code all is done in the right way.

If you always want to keep the root, you can just omit the addToBackStack() call when you originally add the root fragment. Otherwise I think you probably need to find the back-stack name of the fragment on top of the root. You can look through the entries (which are NOT fragment instances!) using backStackEntryCount() and getBackStackEntryAt(). — mrrrk, May 10 '19 at 10:50

there's a trick to pop everything, just:

fm.popBackStack(null, FragmentManager.POP_BACK_STACK_INCLUSIVE);

I want to pop everything before "root" fragment. – Blodhgard Jan 24 '15 at 00:09
