You can create multiple files to hold the SharedPreferences data. The data is stored in the form of a key-value pair. Generally, it is used to cache user local data such as login forms. It’s an interface that allows us to store/modify/delete data locally. Here is the solution: add two dependencies to your gradle implementation 'androidx.preference:preference-ktx:1.2.1' implementation 'androidx.legacy:legacy-preference-v14:1.0.0' delete import. SharedPreferences is part of the Android API since API level 1. ![]() You have successfully integrated the Settings Activity with the app. By the application, using getApplicationContext () By the View, using YourView.getContext () The only one I would not recommend is using getBaseContext ().

Open your app's gradle file ( Your-Project/app/adle) and add the following to the dependencies: dependencies Custom Preferences We'll be using this for the rest of the tutorial.
