Kotlin Programming By Example

By: Iyanu Adelekan

Overview of this book

Kotlin greatly reduces the verbosity of source code. With Google having announced their support for Kotlin as a first-class language for writing Android apps, now's the time learn how to create apps from scratch with Kotlin Kotlin Programming By Example takes you through the building blocks of Kotlin, such as functions and classes. You’ll explore various features of Kotlin by building three applications of varying complexity. For a quick start to Android development, we look at building a classic game, Tetris, and elaborate on object-oriented programming in Kotlin. Our next application will be a messenger app, a level up in terms of complexity. Before moving onto the third app, we take a look at data persistent methods, helping us learn about the storage and retrieval of useful applications. Our final app is a place reviewer: a web application that will make use of the Google Maps API and Place Picker. By the end of this book, you will have gained experience of of creating and deploying Android applications using Kotlin.

Designing the messenger API

To design a fully functional RESTful application programming interface for our messenger android application, we must fully understand the concept of application programming interfaces, Representational State Transfer (REST) and RESTful services.

Application programming interfaces

An application programming interface is a collection of functions, routines, procedures, protocols, and resources that can be used for building software. In other words, an application programming interface—API for short—is a collection of well-defined and appropriately structured methods or channels of communication between software components.

Application programming interfaces can be developed for use...
