This book begins by giving you a strong grasp of Kotlin’s features in the context of Android development and its APIs. Moving on, you’ll take steps toward building stunning applications for Android. The book will show you how to set up the environment, and the difficulty level will grow steadily with the applications covered in the upcoming chapters.
Later on, the book will introduce you to the Android Studio IDE, which plays an integral role in Android development. We’ll use Kotlin’s basic programming concepts such as functions, lambdas, properties, object-oriented code, safety aspects, type parameterization, testing, and concurrency, which will guide you through writing Kotlin code into production. We’ll also show you how to integrate Kotlin into any existing Android project.
