If you have at least basic programming experience (with any language), Peter Sommerhoff’s well-crafted overview and examples will help you get quickly up-to-speed with the Kotlin language, its constructs, and its advanced functional and object-oriented capabilities.

Once you’ve mastered these foundations, Sommerhoff walks you through two complete app development projects, introducing best practices and emerging patterns for writing code that’s robust, concise, readable, and highly performant.

• Understand Kotlin’s goals, principles, advantages, design, and constructs
• Take full advantage of functional programming in the Kotlin environment
• 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
