Build a range of Android applications that address the most common real world issues such as authentication, connecting to synchronous and asynchronous remote sources, rendering complex UIs with Jetpack Compose, and more Key Features Learn Android development hands-on by solving challenging real world problems and developing three practical projects Use the latest features of libraries of Jetpack Compose, Room, CameraX, Exoplayer, and more Learn and apply best practices in a practical way and understanding why they are important Book DescriptionThere are lots of resources on how to create apps using the Android framework and Kotlin, however it can be difficult to find content that will help you solve common problems that most well-known apps developers have had to address. This book will fill that void, assisting you in understanding and resolving those issues, which will be helpful in your day-to-day work. You will start working with a WhatsApp similar app, where you will learn how to reactively process asynchronous messages and render them using Jetpack Compose, as well as create and upload a backup of the messages. The next stop will be to create ‘Packt-agram’, an app like Instagram, focusing on its editing capabilities and using the latest version of CameraX libraries. Finally, we will create our own Netflix app and learn how to playback video using Exoplayer, both in the foreground and background, and how to cast to other devices. By the end of the book, you'll have built three fully functional projects for multiple platforms and gained the knowledge to solve the most common challenges confidently.What you will learn Create complex UIs with Jetpack Compose Structure and modularize apps focusing on further scaling Connect your app to synchronous and asynchronous remote sources Store and cache information and handle its lifecycle Execute periodic tasks using WorkManager Capture and edit photos and videos using CameraX Authenticate securely your users Play videos in the foreground and background of your app and cast them to other devices Who this book is forIf you are a mid-level Android engineer, this book is for you, as it will teach you how to solve issues that occur in real-world apps and can be used as a reference for your day-to-day work. This book can also help Junior engineers too, as it will start exposing you to complex problems and the best practices to solve them. It will be beneficial to have a basic understanding of Android and Kotlin concepts like Views, Activities, Lifecycle, and Kotlin coroutines.
