How to Ensure the Remember Me Checkbox State is Saved in Android Studio

When developing applications, particularly login systems, providing users with the option to save their login details makes for a better user experience. A common feature many applications include is a "Remember Me" checkbox, allowing users to stay logged in even after closing the app.

In this guide, we'll tackle the issue of saving a checkbox state in Android Studio, ensuring your users don’t have to re-enter their login details every time they open your app.

The Problem

You might have encountered this issue before: you build a login feature with a "Remember Me" checkbox—but when the user closes the app and reopens it, the checkbox state resets. This means users must re-enter their email and password each time they return to the login screen. In addition, this can frustrate users who expect to be logged in automatically without needing repeated authentication.

In this guide, we will walk through how to persist that checkbox state using SharedPreferences, ensuring a smooth login experience for users.

The Solution: Using SharedPreferences

SharedPreferences is a simple way to store small amounts of data as key-value pairs in Android apps. It’s perfect for saving user preferences like whether the "Remember Me" checkbox is checked.
