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.

Syntax is a significant part of the programming language, defining a set of rules that must be applied to combinations of symbols. Otherwise, a program can't be compiled, and will be considered incorrect.

  • Defining variables
  • Defining functions
  • Defining classes

package com.packt.learn_spring_for_android_application_development

All citizens of the file belong to this package and must be located in the appropriate folder.
