This article explains how Kotlin Coroutines work under the hood, including how suspension, continuations, and dispatchers work. It provides a deeper understanding of the mechanisms behind coroutines and how they manage asynchronous tasks.

This article explains focus management in Android TV using Jetpack Compose and how focus affects navigation with a remote control. It covers practical techniques for handling, controlling, and improving focus behavior in TV applications.

This article explains how to design Android TV UIs using Jetpack Compose, focusing on content cards, hero elements, and carousels. It covers practical approaches to creating responsive and user-friendly interfaces for TV applications.

The article explains the differences between Standard and Modal Navigation Drawers and demonstrates how to implement them using Jetpack Compose and Android’s Navigation Component.

This article explains how Baseline Profiles improve Android app startup and scrolling performance by pre-compiling frequently used code paths, building on background concepts like ART, Dalvik, and profile-guided optimization. It then walks through generating and testing a Baseline Profile, including special handling for lazy columns with images.

Testing is crucial in Kotlin Multiplatform (KMP) to ensure reliability across platforms. This codelab explores Kotest, a powerful testing framework for Kotlin, covering test source sets (commonTest, jvmTest, iosTest) and Kotest’s integration with JUnit (JVM) and Mocha (JS). You'll set up Kotest in a KMP and Compose Multiplatform (CMP) project, run tests across platforms, and learn different test styles (FunSpec, DescribeSpec, etc.). Through hands-on exercises, you'll write unit tests using Kotest matchers, implement lifecycle hooks, explore property-based testing, configure test parallelism and timeouts, and test coroutines and concurrency. By the end, you'll have a solid foundation in multiplatform testing with Kotest to build robust, scalable applications.

This article explains how to set up Koin dependency injection in a Kotlin Multiplatform project, covering module definitions (single, factory, scoped) and how to initialize Koin across Android, iOS, and Android .TV. It also shows a practical example of passing platform-specific parameters (like OsType) from each platform into shared business logic via Koin.

This article breaks down four major Android architecture patterns—MVC, MVP, MVVM, and MVI—using a restaurant analogy to show how each one handles the flow between the Model and View. It highlights the key evolution: from tightly-coupled Controllers, to strict Presenters, to reactive ViewModels, and finally to MVI's unidirectional Intent-State model.
