Description
Use Kotlin to write more concise, expressive code — and more robust, scalable Android apps Master Google’s industrial-strength object-oriented language for building Android apps faster and more successfully
- Leverage advanced Kotlin features including lambdas, collections, null safety, type inference, and try-with-resources
- Explore powerful coroutines with this guide’s unique, exclusive coverage
- Quickly migrate existing Java app projects to Kotlin
- Jumpstart your Kotlin projects with working code examples and two full sample apps, all available at a companion Github repository
- Leverage advanced Kotlin features including lambdas, collections, null safety, type inference, and try-with-resources
- Explore powerful coroutines with this guide’s unique, exclusive coverage
- Quickly migrate existing Java app projects to Kotlin
- Jumpstart your Kotlin projects with working code examples and two full sample apps, all available at a companion Github repository
The Kotlin language brings state-of-the-art programming techniques and constructs to Android development. Kotlin for Android App Development will help students rapidly understand Kotlin’s principles and techniques, apply Kotlin in production app development, integrate Kotlin with existing Java code, and plan a migration to Kotlin.
For students with at least basic programming experience (with any language), Peter Sommerhoff’s well-crafted overview and examples will help them get quickly up-to-speed with the Kotlin language, its constructs, and its advanced functional and object-oriented capabilities.
Once students have mastered these foundations, Sommerhoff walks them through two complete app development projects, introducing best practices and emerging patterns for writing code that’s robust, concise, readable, and highly performant.

- Write more concise and reusable code using Kotlin’s object-oriented features
- Interoperate with existing Java code, and plan a migration to Kotlin
- Use coroutines to efficiently handle concurrency
- Capture data via third-party APIs, map it to internal data representations, and present it to users
- Master best practices for architecting Kotlin Android apps
- Improve productivity and readability by creating simple domain-specific languages in Kotlin
Write More Robust and Maintainable Android Apps with Kotlin
“Peter Sommerhoff takes a practical approach to teaching Kotlin by providing a larger set of code listings that demonstrate language features and by guiding readers through the development of two Android apps step by step. . . . Peter finds a good balance between what is essential and what can be left to readers, so this book is an efficient yet comprehensible source for starting programming with Kotlin.”
