Course Lessons

Lesson 1

Build your First App

Build your first app: "Dice Roller" that covers basic Android components like displaying texts and images as well as a tour of the Android tools you'll be using throughout this course.

Lesson 2


Designing your app's UI is the first step to a great user experience. This lesson covers all the basics of UI layout design. You'll use all the popular view types with a focus on the ContraintLayout.

Lesson 3

App Navigation

Building multiple screens on Android has never been easier with the Navigation library. You'll get to build a fun trivia app using multiple fragments and conditional navigation.

Lesson 4

Activity & Fragment Lifecycle

Understanding the concept of Lifecycles for both activities and fragments is what makes a great Android developer! Have a treat with this delicious "Dessert Pusher" app.

Lesson 5

App Architecture (UI Layer)

With Architecture Components you'll have the power to design even the most complicated app ideas. Combine ViewModels with LiveData to build this super fun "Guess it" game.

Lesson 6

App Architecture (Persistence)

This lesson is all about data persistence, there are many ways to storing data permanently, but with Room things have become even easier than ever before!

Lesson 7


Everything is better in a list! Recycler View has been - and continues to be - an essential component of any app design. This lesson is all about making your app better with Recycler Views.

Lesson 8

Connect to the Internet

Need some live data in your app? In this lesson you'll use Retrofit to communicate with any API service out there. You'll also use Glide to display images from the web.

Lesson 9

Behind the Scenes

Not everything is displayed on the screen. In Android, there's so much happening in the background and you'll get to build your own background services and tasks in this lesson.

Lesson 10

Designing for Everyone

Coming up with a good design for an app is always hard, but creating a great design is more than just colors and layouts. Let's build an app that is designed for everyone, everywhere!
