Kotlin Coroutines: In Depth

Learn how to implement coroutines in a real-world example of an Android application, with structured layers and decoupled dependencies. You'll see how to test coroutines, handle errors, and structure concurrency in a clean and stable way.

MVP on Android

In this course, you will learn how to build an Android app using the Model-View-Presenter presentation architecture pattern.

Kotlin Flow: Getting Started

Kotlin Flow is a new asynchronous stream library from JetBrains, the company behind the Kotlin language. Sharing many similarities with Rx streams, Kotlin Flow is built on top of Kotlin Coroutines. Get started by learning the concepts and usage patterns for the Flow API within IntelliJ IDEA projects. Then, see Flow in action in an Android app. Note: Flow is experimental in Kotlin 1.3 but will likely be stable in Kotlin 1.4.

MVI on Android

In this course, you will use RxJava to build an app using the Model-View-Intent architecture, learning about components like intents, results, and state.

Dependency Injection with Hilt: Fundamentals

In this dependency injection course, learn how to apply an awesome new library called Hilt, to build dependency graphs, and inject dependencies into Android components in an automatic and lifecycle-aware way, without having to write a ton of boilerplate code, you had to write with Dagger.

Testing With MockK

Learn how and when to use the many powerful features that the MockK Kotlin testing framework provides.

Bottom Navigation

See how to set up Android bottom navigation with Jetpack Navigation, and also see an alternative means of implementing bottom navigation that allows separate back stacks for each tab, the Bottom Navigator library from Pandora.

Retrofit and Coroutines

The old way of making network calls with Retrofit utilizes callbacks. In this course, learn how to greatly simplify Android networking code with an app that retrieves and displays a list of GitHub repositories.

Building with Bazel

Bazel is an open source build system created by Google for compiling large complex codebases. This courses teaches the basics of using building from writing a very simple Java application to compiling an Android app with a lots of dependencies.

Animation with MotionLayout

MotionLayout is a ConstraintLayout subtype that lets you easily add animation to your user interface. See how to set up a MotionLayout with a MotionScene and ConstraintSets that transition your layout between start and end states. You'll also get a preview of the Android Studio 4.0 Motion Editor.

Kotlin/Native and Multiplatform

In this course, you will be introduced to Kotlin/Native and build a Kotlin Multiplatform app that runs on both iOS and Android using shared Kotlin code.

OkHttp Interceptors in Android

Learn how to use OkHttp Interceptors to intercept network requests, log them and also modify them on the fly.

Jetpack Navigation: Getting Started

In this course, learn how to use the Navigation Architecture Component provided by Android Jetpack Library to simplify navigation in your app. It also helps you visualize your app’s navigation flow. You will also learn how to add Animations and Deep links to your navigation flow.

Beginning RxKotlin

In this course, you will be introduced to reactive programming in Kotlin and Android with RxKotlin. You'll learn about observables, subscribing, and more, and how to use RxKotlin in your Android app projects.

Supporting Dark Theme

Android 10 introduced a system Dark theme setting, and modern apps should both support the system setting as well as let users override to their preferred theme. See how to add DayNight themes into your app on Android 10 and earlier versions of Android, and then let your users decide whether to follow the system setting. You'll also learn how to go to a dark theme in battery saver mode.

Server-Side Kotlin with Ktor

Learn how to use the Ktor framework to build a Kotlin web app and API, and see how to deploy the app to the cloud and also run the app in a Docker container.

Dependency Injection with Koin

Learn how to get started with the Dependency Injection framework Koin and how it can make developing CLEAN code and testing easier.

SQLDelight in Android: Getting Started

In this course, we will introduce you to SQLDelight, a generator for typesafe Kotlin code based on SQL database statements, with built-in support for migrations, schema validation and IDE integrations. From initial installation all the way to customization, you’ll learn everything there is to know about this latest invention from Square.

WindowInsets Handling & Keyboard Animations

Until now keyboards and Androids seemed to go in opposite directions. There was no API you could query to learn if the keyboard was open or to know its size. When the keyboard popped up, the screen and views would automatically rearrange themselves without a smooth transition.

In this course learn how to interact with the keyboard via WindowInsets. Read its properties, know if it’s open, and create smooth, synchronous, animations.

Android DataStore

DataStore is Google’s new and improved solution for persisting simple pieces of data by using either key-value pairs or protocol buffers for storing typed objects. It does so using Kotlin Coroutines and Flow to make all the transactions asynchronous, making all the data storing and fetching operations more performant and safe! It’s part of the Jetpack set of tools, so it’s also known as the Jetpack DataStore. In this course, learn how to store simple and complex typed data in Jetpack DataStore as well as migrating existing data from Shared Preferences.

Implementing Picture In Picture Mode In Android

Implement Picture In Picture mode to allow users to watch videos even while they use other apps. See how a real-world app uses PiP, then learn how to add awesome media playback controls to PiP mode for ease of use!

Jetpack Compose Animations

Jetpack Compose is revolutionizing the way Android developers build Android applications, so it’s no surprise that it’s also revolutionizing the ways Android developers create animations! In this course, you’ll learn how to use Jetpack Compose to make practical and visually pleasing animations. You’ll learn how to use simple animations to control things like visibility while also using more complex animations to dazzle your users.

Jetpack Security

Learn how to use the AndroidX Jetpack Security library for managing security keys and encrypting file and preferences data.
