I thought of giving this method a try and while trying I found that using this is super easy. I encountered the registerOnSharedPreferenceChangeListener() method. When I was traversing through the shared preference functions using the the mighty Ctrl+Space, provided by the Android Studio IDE. Of course, there are many ways to overcome this situation like overriding the default onBackPressed() method, overriding the onResume() method of the previous activity and then setting the value again and perhaps many more.īut what I needed was something much simpler, like just check one or two keys of a shared preference and fetch the current value of the keys into some views and display them. While working on one of the applications, I ran into a situation where I had changed the values of some keys in the Shared preference but if the user back pressed, the changes would not be reflected in the previous activity. We know App development is a big task but, there is much fun associated with it.
In this blog, we will learn about using shared Preference Change Listener.
