android – How to pop fragment off backstack-ThrowExceptions

Exception or error:

I have an activity A, which calls fragment Bf, which calls fragment Cf. I want Bf to be placed in the backstack when Cf is called so that users can navigate back to it. However, if a specific button is pressed in Cf, I would like Bf to be removed from the backstack. Is this possible?

I see that there is a popBackStack() function. However, I am a little confused on how this would work. Is it safe to use this function? Is there any possibility that an activity from a different application would be inserted after Bf on the backstack?

Also, is there any way to alter the savedInstanceState of the fragment on the backstack?

I just can’t figure out how to do a robust test on the backstack using the emulator.

How to solve:

You can pop the fragment by name. While adding fragments to the back stack, just give them a name.


Then in Fragment_C, pop the back stack using the name ie.. fragB and include POP_BACK_STACK_INCLUSIVE

someButtonInC.setOnClickListener(new View.OnClickListener() {

    public void onClick(View v) {

        FragmentManager fm = getActivity()
        fm.popBackStack ("fragB", FragmentManager.POP_BACK_STACK_INCLUSIVE);


Three ways to pop Fragment off BackStack

Simply add any of these lines:




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


getActivity().getSupportFragmentManager().popBackStackImmediate(null, FragmentManager.POP_BACK_STACK_INCLUSIVE);

They’re all easy ways to pop fragment off Backstack


first replacing fragment container_view that time we add name as like “Later Transaction”

    profileFragment, "Profile").addToBackStack("Later Transaction").commit();

then on back press button pop the back stack using the Later Transaction name

     int count = getSupportFragmentManager().getBackStackEntryCount();
    if(count > 1) {
     getSupportFragmentManager().popBackStack("Later Transaction", 
    } else {, 
        getString(R.string.exit_app_message), getString(R.string.alert), 
       "Yes","No", new DialogUtils.ActionListner() {
            public void onPositiveAction() {
            public void onNegativeAction() {
