Android architecture has converged. After years of competing patterns — MVP, MVC, MVVM, MVI — the community has settled on a clear, well-supported approach. This article presents the full picture: what to use at each layer, and why. The official Android architecture guide defines three layers with clear responsibilities: Unidirectional Data Flow: state flows down to the UI, events flow up to the... Continue reading →

The Android large screen ecosystem has grown substantially. Foldables, tablets, and Chromebooks running Android apps collectively represent hundreds of millions of active devices. Google has made large screen quality a Play Store ranking signal — making this a business priority, not just a nice-to-have. Never branch on screen size using device type or pixel density. Use Window Size Classes from... Continue reading →

On-device AI has crossed the threshold from research project to production feature. In 2026, Gemini Nano is available on hundreds of millions of Android devices through AICore, and ML Kit provides specialized models for vision, text, and audio tasks — all running locally, privately, and without internet connectivity. Gemini Nano is Google's smallest Gemini model, optimized for on-device inference... Continue reading →

Accessibility is often treated as an afterthought, but it is both a legal requirement in many markets and a quality signal that correlates strongly with overall app polish. Apps built accessibly tend to be better structured, easier to test, and more pleasant to use for everyone — not just users with disabilities. An estimated 15% of the world's population lives with some form of disability.... Continue reading →

A reliable test suite is the best tool for moving fast without breaking things. In 2025 the Android testing ecosystem has matured significantly — this guide covers the stack that works and the patterns that make tests actually useful rather than a maintenance burden. For Android apps, a healthy distribution is roughly: MockK is the Kotlin-first mocking library. It handles coroutines, object... Continue reading →

The Jetpack Navigation Component standardizes navigation in Android apps. Whether you are using Fragments, Compose, or a mix, Navigation gives you a single source of truth for your app's navigation graph, type-safe argument passing, and deep link support out of the box. For pure-Compose apps, use the navigation-compose artifact. Define your graph in a composable function using the NavHost DSL. Nav... Continue reading →

Performance optimization without measurement is guesswork. This article covers the tools and techniques that actually move the needle — from diagnosing startup time to eliminating jank in scrolling lists. Before changing any code, establish a baseline with reproducible benchmarks. The Macrobenchmark library lets you measure startup time, scrolling performance, and custom scenarios in a controlled...
