Answer 1

You can add a tag to each fragment while adding them to the backstack and then popfragment from backstack till the fragment with the tag you want is not reached.

FragmentManager fm = getFragmentManager();

for (int i = fm.getBackStackEntryCount() - 1; i > 0; i--) {
    if (!fm.getBackStackEntryAt(i).getName().equalsIgnoreCase(tagname)) {
        fm.popBackStack();
    }
    else
    {
     break;
    }
}

Answer 2

If you are using AndroidX navigation, you can use the following:

findNavController().popBackStack(R.id.FragmentB, false)

Answer 3

You can call the function below while you are in Fragment E:

getFragmentManager().popBackStack("tag", 0);

Here the tag is string passed as tag while adding fragment B to backstack.

Answer 4

tldr: try using fragmentManager instead of supportFragmentManager if the code doesn't work

solution: fragmentManager.popBackStackImmediate(tagName, 0)

I know it's an old question but after spending a few hours on this, I wasn't able to get close to the desired result.

I was using supportFragmentManager and the code was:

supportFragmentManager.popBackStackImmediate(tagName, 0)

but it wasn't working as intended neither according to what was written in the documentation. Just as a fluke I thought about using the fragmentManager instead of the supportFragmentManager and voila, it worked!

So for anyone stuck on this, maybe give this a try.

Use following code for pop back stack entry:

 FragmentManager fm = getSupportFragmentManager();

    if (fm.getBackStackEntryCount() > 0) {

        fm.popBackStack();

    }else {
        super.onBackPressed();
    }
