In this course you will build an Android app with persistent storage (specifically Shared Preferences) in Android Studio. What is meant by persistent storage is that when a user exits an app and then restart it, the app will remember some information that the user gave it previously. This app has four input boxes where the user is being asked to enter a name, address, phone number, and email address. Beneath that section the user will be asked to use radio buttons to indicate the part of the day they prefer, Morning, Afternoon, Evening, or Night. The ability to save and retrieve information is a fundamental part of practically all apps and is essential knowledge for any aspiring app developer and those who like to create apps out of curiosity for fun.
