Android

Build 15 real-world Android sensor apps while mastering Kotlin, Jetpack Compose, CameraX, GPS, Biometrics, Health APIs, and Sensor Fusion.

Master Kotlin Coroutines and Flow from the ground up through real Android projects, production patterns, and best practices used by senior Android engineers.

Jetpack Compose is redefining Android UI development with a modern declarative approach. Mastering Jetpack Compose teaches you the fundamentals, advanced techniques, and production-ready patterns you need to build high-quality Android applications with confidence.

Stop writing tightly coupled Android code. Learn how to structure your apps with powerful Dependency Injection using Hilt and Koin—from beginner concepts to production-ready architectures.

Build Android applications that scale with confidence. Android App Architecture Mastery (2026 Edition) delivers a production-focused blueprint for designing modular, testable, and maintainable apps using Clean Architecture, MVVM, MVI, Kotlin Coroutines, Flow, Hilt, Jetpack Compose, and modern Android engineering best practices.

Go beyond Kotlin and unlock the full power of Android native development with practical NDK projects in security, audio, video, computer vision, and on-device AI.

Stop memorizing hooks. Start understanding how React Native rendering, state, effects, and re-renders really work.

Migrate existing, high-traffic production Android and iOS applications to Kotlin Multiplatform (KMP) and Compose Multiplatform (CMP) systematically—without pausing feature development or compromising release stability.

This book introduces screenshot testing (also called visual or snapshot testing): an automated approach that records a reference image of the expected design, then compares each test run against it to detect visual changes. It’s a natural complement to functional UI tests, which verify behavior but not appearance. The book focuses on the fundamental principles that apply to all frameworks. It works through the questions teams actually face: when to use screenshot tests and when not to, what to verify, which frameworks and tools fit your workflow, how to generate tests from preview functions in Jetpack Compose, how to integrate tests into a CI/CD pipeline, and how to optimize the whole process. By the end, you’ll be able to choose the framework that best suits your project and build a safety net that catches visual bugs before release. Every concept is demonstrated with a demo mood tracker application, with all code available online.

In this book, you won't just learn to create static screens; you will learn to build dynamic interfaces (Server-Driven UI). We will start with layout in Flutter, move through the robust construction of APIs and models using Laravel and Django, and finish by implementing a "Widget Mix" so the backend dictates how the app looks. By the end, you will have built a system where you can update your users' UI in real-time, without having to wait for app store approvals. This is the solid foundation you need to develop scalable and modern applications.

En este libro, no solo aprenderás a crear pantallas estáticas; aprenderás a construir interfaces dinámicas (Server-Driven UI). Comenzaremos con la maquetación en Flutter, pasaremos por la construcción robusta de APIs y modelos usando Laravel y Django, y terminaremos implementando un "Mix de Widgets" para que el backend dicte cómo se ve la app. Al finalizar, habrás construido un sistema donde podrás actualizar la UI de tus usuarios en tiempo real, sin tener que esperar las aprobaciones de las tiendas de aplicaciones. Esta es la base sólida que necesitas para desarrollar aplicaciones escalables y modernas.

Understand React Native internals with zero guesswork.

Takes you from building React Native apps to engineering production systems that scale, recover from failure, and run reliably at real-world traffic.

Learn React Native from first principles to production-ready architecture, building fast, scalable apps with real-world mobile engineering practices.

Stop treating Android like a black box and start thinking like the engineers who build it.
