Book DescriptionWith resources on Android and Kotlin abound, it's difficult to find content that focuses on resolving common challenges faced by app developers. This book by Gema Socorro Rodríguez - a Google Developer Expert for Android with over 15 years of experience and a proven track record as an effective instructor - is designed to bridge the gap between theory and real-world application. It equips you with the skills to tackle everyday problems in Android development through hands-on projects.
Under Gema's expert guidance, you'll build three sophisticated Android projects. You'll start your development journey by building a WhatsApp-like application, learning how to process asynchronous messages reactively, render them using Jetpack Compose, and advance to creating and uploading a backup of these messages. Next, you'll channel your creativity into Packtagram, an Instagram-inspired app that offers advanced photo-editing capabilities using the latest CameraX libraries. Your final project will be a Netflix-style app, integrating video playback functionality with ExoPlayer for both foreground and background operations, and implementing device casting features.
By the end of this book, you'll have crafted three fully functional, multi-platform projects and gained the confidence to solve the most common challenges in Android development.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 forIf 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.
