Kotlin from Zero to Mastery: Android Development

Kotlin from Zero to Mastery: Android Development is a Kotlin primer and practical tutorial in Tsinghua University Press's Mobile Development Series, written by Ouyang Shen, who has more than a decade of software development experience. The book has 10 chapters in three parts. Part One (Chapter 1) introduces the relationship between Kotlin and Android development, covering in detail Android Studio installation and startup, creating a Kotlin project, SDK installation and Gradle plugin upgrades, build configuration adjustments, converting Java code to Kotlin, and peripheral technologies such as the Anko library and lambda expressions. Part Two (Chapters 2–5) systematically explains Kotlin language fundamentals: basic data types, arrays, strings, and collections; control statements including conditionals, loops, null safety, and equality checks; functions including default parameters, named parameters, varargs, generic functions, inline functions, higher-order functions, and extension functions; and object-oriented features including class construction, members, companion objects, inheritance, abstract classes, interfaces, nested classes, enum classes, sealed classes, and data classes. Part Three (Chapters 6–10) turns to actual app development, covering simple controls such as buttons, checkboxes, and radio buttons plus linear, relative, and constraint layouts; ListView, RecyclerView, Material Design, ViewPager with Fragment, and Broadcast; and data storage, custom controls, and network communication. An e-commerce app—with login, channel, shopping cart, group buying, and upgrade modules—runs through the book as a case study, grounding syntax in real interfaces. It suits Android developers and Kotlin beginners studying on their own, and can serve as a coursebook for schools and training institutions.
