Building an Android Application – Tetris

In the previous chapter, we took a concise look at crucial topics pertaining to the core Kotlin language. These topics took us through the fundamentals of Kotlin as well as the powerful object-oriented programming approach to software development it puts at our disposal. In this chapter, we will put the knowledge we gained from the previous chapter to good use by developing an Android application.

In this chapter, you will learn about the following topics:

Android application components
Views
View groups
Layout constraints
Implementing layouts with XML
String and dimension resources
Handling input events

We will learn these topics through a hands-on approach by implementing the layouts and components of a classic game, Tetris, in the form of an Android application. As we are developing the game in the form of an Android application...

Description

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.

The idea behind this book sounded great, but the execution was lacking. The description promises to 'teach the building blocks of the Kotlin programming language' and is meant for 'those new to Kotlin.' And the first chapter does go over some of the most rudimentary syntax of the language, like how to declare a variable. But that is the last time it really tries to educate the reader about the language. The rest of the book is just a code dump and leaves understanding unexplained syntax and language features an exercise for the reader to figure out. Many times what little explanatory text there is does not agree with the code that is provided. It spends more time explaining how to use Android Studio than it does on how the code actually works.This book may be good for someone that already has a firm grasp on Kotlin and its libraries, and is looking for examples on how to move into app or web development, but it is not for someone that is looking to learn Kotlin, by example or otherwise.

Clearly written in a rush and of a poor quality. Due to the amount of mistakes, it is hard to follow. Whilst the attached image doesn't express how the book can be hard follow, it does show how sloppy the proof reading and editing is.
