Android: How to remove fragments from backstack?

I have situation where I want to clear all fragments from backstack except the one which is visible(i.e. on top)

For example, There are four fragments in backstack A->B->C->D (D is on top)

Now I want to remove fragments A,B,C from backstack. But the constraint is there should not be any visible effect on fragment D while removing history from backstack.

This is my code. 

FragmentManager fm = getActivity().getSupportFragmentManager();
                Bundle bundle = new Bundle();
                OrderReceiptFragment orderReceiptFragment = new OrderReceiptFragment();
                bundle.putSerializable("orderHistory", orderHistory);
                orderReceiptFragment.setArguments(bundle);
                CommonUtil.clearBackstack(fm);
                fm.beginTransaction().setCustomAnimations(R.anim.enter_from_left,
                        R.anim.exit_to_right)
                        .replace(R.id.container, orderReceiptFragment).commit();

method to clearbackstack

public static void clearBackstack(FragmentManager fragmentManager) {    
    fragmentManager.popBackStack(0, FragmentManager.POP_BACK_STACK_INCLUSIVE);
}

Here the problem is - while clearing the backstack, for some milliseconds the first fragment from the backstack gets visible. Which looks weird. Does anybody have any solution for this?

Very Simple:

FragmentManager frgManager;
frgManager = getActivity().getSupportFragmentManager();
frgManager.popBackStack("null", FragmentManager.POP_BACK_STACK_INCLUSIVE);

Try this code:

 FragmentManager _manager = getActivity().getSupportFragmentManager();
_manager.popBackStack(null, FragmentManager.POP_BACK_STACK_INCLUSIVE)

If you are trying to make it so that the only layout in the history at any given time is the one that you are currently viewing, you can do the following in the manifest:

android:noHistory="true"

Put that in for each fragment/activity that you don't want to show up in the history.

How about this-

mFragmentManager.popBackStack(null, FragmentManager.POP_BACK_STACK_INCLUSIVE)
