Clean Architecture for Android: Creating scalable, maintainable, and testable native Android apps - 2nd Edition
About this ebook
Clean architecture has been gaining traction in recent years as a way of developing scalable, testable, and maintainable Android applications. It works as well for single developers as it does for larger teams of many developers.
This book will take you through the ideas behind Clean Architecture. This new edition significantly expands the original content with detailed layer-by-layer implementation chapters, modern Jetpack Compose examples throughout, and triple the testing coverage, including the robot pattern and dedicated server mocking techniques. Lastly, it will provide you with real-life examples of applying the different principles of Clean Architecture and highlighting the benefits of adopting them.
By the end of this book, you should be comfortable developing Clean Architecture-based Android apps. Given a feature requirement, you would be able to break the implementation down into the different components required. Your code will benefit from high test coverage. It will be easy to modify and extend your app without needing to periodically rewrite it completely. Changes to the UI, API contracts or persistence solution will become easy and safe to implement.
WHAT YOU WILL LEARN
● How to develop a Clean Architecture Android app from the ground up.
● The steps for migrating an existing app to Clean Architecture.
● How to approach introducing a new feature.
● How to unit test the different classes of Clean Architecture apps.
● The rules for writing end-to-end tests to verify your app behavior.
