Learn Spring for Android Application Development

By: S. M. Mohi Us Sunnat, Igor Kucherenko

Overview of this book

As the new official language for Android, Kotlin is attracting new as well as existing Android developers. As most developers are still working with Java and want to switch to Kotlin, they find a combination of these two appealing. This book addresses this interest by bringing together Spring, a widely used Java SE framework for building enterprise-grade applications, and Kotlin. Learn Spring for Android Application Development will guide you in leveraging some of the powerful modules of the Spring Framework to build lightweight and robust Android apps using Kotlin. You will work with various modules, such as Spring AOP, Dependency Injection, and Inversion of Control, to develop applications with better dependency management. You’ll also explore other modules of the Spring Framework, such as Spring MVC, Spring Boot, and Spring Security. Each chapter has practice exercises at the end for you to assess your learning. By the end of the book, you will be fully equipped to develop Android applications with Spring technologies.

Coroutines

A coroutine is a powerful feature of the Kotlin programming language. Its main objective is to allow for suspending a function while it waits for the result of another function that invokes a long-term operation. This feature allows us to write asynchronous code without callbacks in a sequential way.

This section will cover the following topics:

  • Coroutine basics
  • Call stacks
  • Coroutine testing
  • Coroutine scope

If you are familiar with the concept of threads, you will know that each thread has its own call stack. We will cover the thread's call stack topic in the next section. The creation of a new thread is a complex operation that takes about two megabytes of memory. Coroutines use a thread...
