In this book, you’ll learn to use Android debugging tools to make your app optimized and bug-free through step-by-step tutorials.

Kotlin Coroutines by Tutorials

The importance of concurrency is discovered quite early on by people who start with Android development. Android is inherently asynchronous and event-driven, with strict requirements as to on which thread certain things can happen.

Add to this the often-cumbersome Java callback interfaces, and you will be trapped in spaghetti code pretty quickly (aptly termed as “Callback Hell”). No matter how many coding patterns you use to avoid that, you will have to encounter the state change across multiple threads in one way or the other.

The only way to create a responsive app is by leaving the UI thread as free as possible, letting all the hard work be done asynchronously by background threads.

Kotlin Coroutines by Tutorials will teach you the techniques you need to solve common programming problems using asynchronous programming.

Functional Programming in Kotlin by Tutorials

Functional programming is a powerful paradigm for building your applications. This book will teach you the fundamentals of functional programming in a practical, hands-on way, while showing you how you can safely handle errors and state changes in your programs.

Android Animations by Tutorials

This is a book about creating meaningful motion through animation in Android for developers who are familiar with the platform but want to create more visually stunning apps. Starting with simple view animations, this book will move through transition animations including shared element animations, list animations, gestures and scrolling. It ends with a taste of using animations in Jetpack Compose.

Saving Data on Android

Save Data on Android!

Persisting data has always been a fundamental part of any app. Saving data locally or remotely with modern techniques for synchronization allows your app to always be up-to-date, reactively presenting fresh data.

This book is for intermediate Kotlin or Android developers who want to know how to persist data using the standard Android APIs, the Jetpack DataStore mechanism, the Room Android Architecture Component or Google Firebase’s offerings.

Topics Covered in This Book Persistence with Android SDK: Learn how to manage files, SharedPreferences and SQLite databases using the APIs the Android platform offers by default. Jetpack DataStore: Learn how to persist simple data by using key-value pairs. This is Google’s new and improved solution for saving data. In this book, you’ll learn basics about Preferences DataStore and how to migrate from SharedPreferences. Using Room: Room is one of the most important Google Architecture Components. It allows you to manage entities and relationships using classic Object-Oriented principles. In this book, you’ll learn everything you need to store data and run queries on top of it. Managing relationships with Room: A database has entities and relationships. In this book, you’ll learn how to design your database and manage relationships both eagerly and lazily. Managing and testing migrations: Every app evolves over time. Here, you’ll learn how to manage migrations with Room and how to test them properly. Firebase Realtime Database: Google provides tools to manage data both locally and remotely through the Firebase platform. With the Firebase Realtime Database, you can manage and keep data in sync, simply and efficiently. Cloud Storage: Another option Google provides is Cloud Storage, which lets you leverage all the power of Google’s infrastructure to manage your data and run expensive queries.
