Key Features:

Use the latest features of libraries in Jetpack Compose, Room, CameraX, ExoPlayer, and more
Leverage best practices for UI creation, app structure, data handling, and lifecycle management
Book Description:
Finding resources on creating apps with the Android framework and Kotlin is easy, but discovering content that addresses the common challenges faced by app developers is difficult. This book is designed to bridge that gap and equip you with the skills to tackle everyday problems in Android development.
You'll get hands on with Android development by building an app similar to WhatsApp. Next, you'll learn how to process asynchronous messages reactively, render them using Jetpack Compose, and advance to creating and uploading a backup of these messages. As you progress, you'll develop Packtagram, an app inspired by Instagram, focused on advanced photo-editing capabilities using the latest CameraX libraries. Finally, you'll build your own Netflix-like app, integrating video playback functionality with ExoPlayer for both foreground and background operations, and enabling casting to other devices.
By the end of this book, you'll have crafted three fully functional projects across multiple platforms and gained the expertise to solve the most common challenges in Android development confidently.
What you will learn:
Create complex UIs with Jetpack Compose
Structure and modularize apps with a focus on further scaling
Connect your app to synchronous and asynchronous remote sources
Store and cache information and manage the lifecycle of this data
Execute periodic tasks using WorkManager
Capture and edit photos and videos using CameraX
Authenticate your users securely
Play videos in the foreground and background and cast them to other devices
Who this book is for:
If you're a mid-level Android engineer, this book is for you as it will not only teach you how to solve issues that occur in real-world apps but also benefit you in your day-to-day work. This book will also help junior engineers who want to get exposed to complex problems and explore best practices to solve them. A basic understanding of Android and Kotlin concepts such as views, activities, lifecycle, and Kotlin coroutines will be useful to get the most out of this book.
