When should you use SharedPreferences in Android development?

SharedPreferences is a key-value storage system in Android that is used to store small amounts of data such as user preferences, settings, and simple application state management. It is ideal for scenarios where you need to save simple data types like strings, booleans, integers, etc.

You should consider using SharedPreferences in Android development when:

• You need to save user settings or preferences.
• You want to store login states or session information.
• You need to maintain simple app states that do not require complex structures.
• You want to save data that should remain persistent even after the app is closed.

For example, if you want to save a user's preferred theme choice, you can use SharedPreferences as follows:

SharedPreferences sharedPreferences = getSharedPreferences("AppPreferences", MODE_PRIVATE);
        SharedPreferences.Editor editor = sharedPreferences.edit();
        editor.putString("theme", "dark");
        editor.apply(); // or editor.commit();
