Instead of using edit.commit();, you should use edit.apply();. Apply will update the preference object instantly and will save the new values asynchronously, so allowing you to read the latest values.

Source - Also read detailed difference between commit() and apply() in this SO Post.

The "Source" post referenced above also states pretty much the same problem and switching to apply() seems to have resolved the issue there.

Problem statement in the referenced post:

The problem is that when I am accessing this values, it is not returning updated values, it gives me a value of SharedPreferences.

But when I am confirming the data in XML file ,the data updated in that.

PS: And the reason that the same code block is not working on this one app and working on all other apps could also be that you are either using the block at different places or updating the value somewhere else too.
