Fragment still exists after remove?

1 Add two fragments to FragmentManager

FragmentManager fm = getSupportFragmentManager();
FragmentTransaction ft1 = fm.beginTransaction();
ft1.add(containerId, fragment1, "fragment1");
ft1.addToBackStack(null);
ft1.commitAllowingStateLoss();

FragmentTransaction ft2 = fm.beginTransaction();
ft2.add(containerId, fragment2, "fragment2");
ft2.addToBackStack(null);
ft2.commitAllowingStateLoss();

2 Change mobile setting Developer Options-> Don't Keep Activities-> ON

3 Remove all fragments after activity was recreated

FragmentTransaction ft3 = fm.beginTransaction();
for(Fragment f : fm.getFragments())  ft3.remove(f); 
ft3.commitAllowingStateLoss();

My question is why fm.findFragmentByTag("fragment1") is NOT null after remove?

try this code for remove the fragment

FragmentManager manager = getActivity().getSupportFragmentManager();
FragmentTransaction trans = manager.beginTransaction();
trans.remove(myFrag);
trans.commit();
manager.popBackStack();

i think you have not add this method

manager.popBackStack();

or

getSupportFragmentManager().popBackStack()

Fragments, (), the replace transaction is saved to the back stack so the user can reverse the transaction and bring back the previous fragment by pressing the Back button. use popBackStackImmediate() instead of popBackStack() which insure fragment is removed from backstack immediately. transection's remove method does not remove fragment from backstack it just for transection.

Thus, only while the activity is in the resumed state can the lifecycle of a fragment change independently. However, when the activity leaves the resumed state, the fragment again is pushed through its lifecycle by the activity. Example


instead of the

ft1.add(containerId, fragment1, "fragment1");

try

ft1.replace(containerId, fragment1, "fragment1");

and use the

fragmentmanager.popBackStack();

However, if you just restore the database on top of an existing replicated database as shown below, you get orphan replication configurations. You can cleanup many processes to drop the Log Reader and Distribution agent jobs, but even after that if you query the "Distribution.dbo.MSpublications" table you often still see that records exist.


you should commit individual fragment remove transactions.

this code will commit after loop complete

for(Fragment f : fm.getFragments())  ft3.remove(f); 
ft3.commitAllowingStateLoss();

instead of use brackets

for(Fragment f : fm.getFragments()){
 ft3.remove(f); 
 ft3.commitAllowingStateLoss();
}
