SharedPreferences.onSharedPreferenceChangeListener not being called consistently

Question

I\'m registering a preference change listener like this (in the onCreate() of my main activity):

SharedPreferences prefs = PreferenceManager.get         


        

Answer 1

Kotlin Code for register SharedPreferenceChangeListener it detect when change will happening on the saved key :

  PreferenceManager.getDefaultSharedPreferences(this)
        .registerOnSharedPreferenceChangeListener { sharedPreferences, key ->
            if(key=="language") {
                //Do Something 
            }
        }

you can put this code in onStart() , or somewhere else.. *Consider that you must use

 if(key=="YourKey")

or your codes inside "//Do Something " block will be run wrongly for every change that will happening in any other key in sharedPreferences
