Wrong fragment displayed when going to recents and back

Question

I have an Activity A which launches a fragment F, which then gets replaced with another fragment F2.

A -> F -> F2

If I'm at F2, press the recents button, and go back into the app, I expect it to still show F2, but it instead shows F.

I'm replacing fragments using this code:

FragmentManager fragmentManager = activity.getSupportFragmentManager();
                fragmentManager.beginTransaction()
                        .replace(container.getId(), StoryFragment.newInstance(story)).addToBackStack(null).commit();

I've tested this with different fragments, and it turns out that the problem is going from fragment to fragment. It doesn't matter which fragments they are, if there's a fragment that replaces itself with another fragment, then I will have this problem. For example, A -> F2 -> F3 will show F2 when it should show F3.

I've tried adding things to onSaveInstance and onPause, but haven't been successful in doing so. Any help is appreciated.

Please share your code regarding fragment transaction. – mnp343 Apr 27 '19 at 03:55 — mnp343, Apr 27 '19 at 03:55

I added the code for the fragment transaction. – Austin Hsieh Apr 27 '19 at 05:53 — Austin Hsieh, Apr 27 '19 at 05:53

Turns out the problem was that I accidentally added android:noHistory="true" in the android manifest, for the activity I was using to launch the fragments. Removing it fixed my problem.
