About the course

The Android Developer Fundamentals course was created by the Google Developers Training team. To take the course, you must have experience with the Java programming language.

The course materials include:

Each lesson contains a slide deck, a concepts chapter, and in most cases, one or more codelabs. As you work through the codelabs, you create apps as a way to practice and perfect the skills you're learning. Some lessons are purely conceptual and don't have codelabs.

The materials are freely available online for use by instructors, or for self-study by anyone who knows the Java programming language.

What does the course cover?

The course includes four teaching units, each of which includes several lessons:

Unit 1: Get started

This unit covers installing Android Studio, understanding project structure, building your first app, creating activities, testing your apps, and using the Android Support Library.

First, you deploy a simple Hello World app. You go on to create an app with a simple activity, and then you create a multi-screen app that passes data between activities. You also learn how to use the Android Support Library to provide backward-compatibility with earlier versions of the Android system for your app.

Unit 2: User experience

This unit covers how to get input from the user, implement navigation strategies, use themes and styles, test your user interface, and follow Material Design principles.

You create apps that use menus and tabs for navigation, and input controls such as spinners and picker dialogs to get information from the user. You learn how to extract resources to create a style from an instance of a user interface element. You write an app that displays a word list in a recycler view (and you learn why it's better to use a recycler view than a plain scrolling list).

You also build a score-keeping app to explore Material Design guidelines.

Unit 3: Working in the background

This unit covers how to do background work, how to schedule tasks, and how to trigger events. It covers the performance implications of executing work in the background, as well as best practices for reducing battery drain. You learn how Android determines which apps to keep running and which to stop when resources run low.

You write an app that connects to the Internet in a background thread to find the author of any book. You also build apps that send notifications and schedule tasks, and you learn how to implement scheduling functionality for apps that run on earlier versions of Android.

Unit 4: Saving user data

This unit discusses how to store user data. You learn how to use shared preferences to save simple key value pairs, then you learn how to use the Room database to save, retrieve, and update user data. This unit also introduces you to the Android Architecture Components, which represent best practices for structuring your app.
