In this course, you will learn about the importance of data persistence when building an Android app. We'll introduce you to the fundamentals of SQL, the programming language needed to interact with an SQLite relational database. SQLite is a commonly used method to store large sets of data locally on an Android device.

You'll also learn how to work with Content Providers, which help your data storage to be bug free and to be shared, if you choose, with other apps.

If you’re curious about the road even farther ahead, these are the free courses that make up the Android Basics Nanodegree, in order:

  • Android Basics: User Interface
  • Android Basics: User Input
  • Android Basics: Multiscreen Apps
  • Android Basics: Networking
  • Android Basics: Data Storage (This Course)

Why Take This Course?

Data storage is an important facet of your favorite Android apps, and it can help you make compelling apps! Data storage allows your users to leave their mark on your app and have that mark persist over time.

Additionally, building data storage into your Android app is a skill that many employers look for when selecting Android developers.


Lesson 1

In the first lesson, you will learn about SQL on its own, using a command line tool. This will give you a foundation of knowledge about databases.

Lesson 2

In the next lesson, you'll bring your SQL knowledge into the Android context by building out the first piece of an app to help with a pet shelter.

Lesson 3 ( coming soon, September 2016 )

In lesson 3 you'll learn about Content Providers, which are instrumental in allowing your app to keep its data clean and to share that data, if you choose, with other apps.

Lesson 4 ( coming soon, September 2016 )

In this lesson, you'll learn more about Content Providers and you'll finish the Pets app!
