java - Avoid recreating activity when Dark theme was changed outside of app (just ignore )

Question

My problem: when the user changes the theme from the notification menu (means outside the application), it is getting recreated and data is loaded again, which is not my app's requirement. Any change in theme from outside, should not affect my inner application theme. I am not sure it's possible or not.

P.S. I would appreciate any help. It is one of my first questions, don't judge me so strong. :)

Answer 1

Don't stop the theme change instead store your data in viewModels.

The ViewModel class is designed to store and manage UI-related data in a lifecycle conscious way. The ViewModel class allows data to survive configuration changes such as screen rotations or theme change.
