KotlinConf 2025 unveiled Rich Errors, a new union‑type based error‑handling model that replaces try‑catch and Result with explicit success‑or‑error return types, improving type safety, readability, and testability for Kotlin developers.
This article explores Kotlin’s runCatching function, compares it with traditional try‑catch‑finally, demonstrates its usage with practical code examples, explains the Result type and its methods, and provides best‑practice guidelines for resource management and when to prefer runCatching over classic exception handling.
Apple’s newly announced Swift Android Workgroup aims to bring Swift natively to Android, sparking industry debate over a potential shift in mobile development, the strategic motivations behind Apple’s move, Kotlin’s response, and the broader impact on developers’ skill sets and career prospects.
This article examines the most frequent side‑effect errors developers make in Jetpack Compose, explains why each mistake leads to performance or correctness issues, and provides clear, code‑driven solutions to help both beginners and seasoned Android developers write efficient, reliable UI code.
This article compares Kotlin Channel and Flow, explains their design differences, outlines when to prefer each tool, provides step‑by‑step usage instructions, showcases four channel types, presents real‑world Android examples, and covers advanced patterns and exception handling for robust coroutine communication.
This article compares Kotlin Channel and Flow, explains their distinct characteristics, shows when to prefer each in Android coroutine programming, provides step‑by‑step usage, multiple channel implementations, real‑world examples, advanced fan‑in/fan‑out patterns, and robust exception handling.
This article explains how Kotlin coroutine cancellation works, why catching CancellationException can create zombie coroutines, and provides concrete patterns—using isActive, coroutineContext.ensureActive(), and proper try‑catch placement—to reliably stop repeating tasks without resource leaks.
Explore the complete guide to implementing shared element transitions in Jetpack Compose, covering essential APIs like SharedTransitionLayout, Modifier.sharedElement, and Modifier.sharedBounds, with detailed code examples, common pitfalls, container transforms, resize modes, and practical solutions for smooth, hero‑style animations across Android screens.
This article explains how Kotlin treats lambda expressions as distinct objects, causing two data class instances with identical lambda bodies to be unequal, demonstrates the problem with code examples, and shows how extracting the lambda into a shared reference restores proper equality, highlighting implications for equals, hashCode, and Compose.
This article traces the evolution of Android's Model‑View‑Intent (MVI) architecture from its MVC and Flux roots, clarifies common misconceptions versus Redux and MVVM, and provides concrete Kotlin code examples and guidelines for implementing a truly unidirectional, immutable‑state MVI pattern in mobile apps.
