Kurzbeschreibung des Verlags

Stop shipping the bugs that compile.Kotlin removed an entire category of crashes from Android. Then it created a new one: perfectly valid code, passes review, and quietly does the wrong thing.A data class copy() that shares its list with the original. A coroutine that ignores cancel() and keeps running. A database migration flag that deletes every user's data the moment they update. None of these throw an error. All of them reach production.Kotlin from Zero to Master teaches you Kotlin from the very first line of syntax through to a complete, offline-first Android application - and flags all 113 of those traps along the way.What you will learn- The language, properly. Variables, null safety, functions, classes, sealed types, generics and delegation, with every confusing edge explained rather than skipped.- Collections and functional Kotlin. The operator toolbox that turns forty lines of loop into one readable line.- Coroutines and Flow. Suspend functions, structured concurrency, cancellation, StateFlow and SharedFlow - explained without the jargon.- Modern Android with Jetpack Compose. State and recomposition, ViewModel, type-safe navigation, Material 3.- Real architecture. Room, Retrofit, Hilt, repositories, offline-first data flow, and tests that run in milliseconds.- One complete app. TaskTide is built end-to-end in Chapter 35 using every idea in the book.Why this book is differentMost programming books teach you what the language can do. This one also teaches you what it will let you do wrong.Every chapter carries Confusion Trap boxes marking code that compiles cleanly and behaves badly. They are collected from real production Android work, and indexed at the back as a self-audit checklist. If you cannot explain one in a sentence, you know exactly which chapter to reread.Who it is for- Complete beginners. Start at Chapter 1. No prior programming experience assumed.- Java and Android developers moving to Kotlin, coroutines and Compose.- Developers from Python, JavaScript or Swift who want the syntax fast and the gotchas faster.- Interview candidates. The chapter recaps and the trap index make an efficient revision pass.Inside40 chapters. 6 parts. 113 Confusion Traps. 1 complete Android app. Plus a quick reference, a working Gradle version catalog, and a glossary written the way a developer would explain it.Written for Kotlin 2.x, Jetpack Compose, Material 3 and current Android tooling. Every listing is code you can actually run. Type it, break it, and understand exactly why it broke.Scroll up and start reading today.
