Key benefits

• Leverage specific features of Kotlin to ease Android application development

• Write code based on both object oriented and functional programming to build robust applications

• Filled with various practical examples so you can easily apply your knowledge to real world scenarios

• Identify the improved way of dealing with common Java patterns

Description

Nowadays, improved application development does not just mean building better performing applications. It has become crucial to find improved ways of writing code. Kotlin is a language that helps developers build amazing Android applications easily and effectively. This book discusses Kotlin features in context of Android development. It demonstrates how common examples that are typical for Android development, can be simplified using Kotlin. It also shows all the benefits, improvements and new possibilities provided by this language. The book is divided in three modules that show the power of Kotlin and teach you how to use it properly. Each module present features in different levels of advancement. The first module covers Kotlin basics. This module will lay a firm foundation for the rest of the chapters so you are able to read and understand most of the Kotlin code. The next module dives deeper into the building blocks of Kotlin, such as functions, classes, and function types. You will learn how Kotlin brings many improvements to the table by improving common Java concepts and decreasing code verbosity. The last module presents features that are not present in Java. You will learn how certain tasks can be achieved in simpler ways thanks to Kotlin. Through the book, you will learn how to use Kotlin for Android development. You will get to know and understand most important Kotlin features, and how they can be used. You will be ready to start your own adventure with Android development with Kotlin.

What you will learn

? Run a Kotlin application and understand the integration with Android Studio

? Incorporate Kotlin into new/existing Android Java based project

? Learn about Kotlin type system to deal with null safety and immutability

Excellent book. This is for Android developers who would like to learn how to apply Kotlin paradigms to typical Android development patterns. Makes for a very practical approach to teaching Kotlin.

Good explanation of Kotlin and advantages over Java. I expected more Android references given the book title so that aspect is a little underwhelming since I am primarily concerned with learning Kotlin for Android development. Though, the last chapter is dedicated to building a gallery app (which I've yet to reach).English is not great, and the grammatical errors don't help, but it is still readable overall. Definitely seems like a number of the issues should have been caught prior to publishing.Overall, so far, I am pleased with the content. My rating may change from a 3 star once I finish reading the entire book.

I have made it halfway through this book and only because I worked through a much better book before I read this one.Android Studio Development Essentials by Neil Smyth is an example of a GOOD Android Studio Tutorial.Android Development with Kotlin by Marcin Moskala is an example of a BAD Android Studio Tutorial.When I see a code example " println(Text) " I know the author is not using Android Studio.When I see Github listing just code snippets instead of working examples I know the author is not using Android Studio.When I see Github code organized in Chapters and no Chapter numbers in the downloaded book I know the editor did not read all of the content.I can work around the broken english in this book and I really want to learn Kotlin on Android Studio, I guess the only way I will is when Neil Smyth writes a Kotlin version of his Android Studio Development Essentials.

The breadth of coverage and touching on Android are valuable and the authors clearly have a great deal of knowledge about Kotlin but the book is severely let down by typos, poor grammar, code sample errors (one defines a class called Snail but instantiates one called Sneil!), duplicated text, images that are unreadable on a Kindle and poor English which is distracting (it's instead of its, sentences missing definite/indefinite articles, missing words, capital letters in the middle of sentences, etc). It's not an exaggeration to say most pages have errors on them, making it incredibly difficult to read and very poor value for money. Even one of the book's chapter *titles* has a glaring typo in it ("View binging" instead of "View binding"!). It's clear this book was not even looked at by a technical book editor. Packt told me they are now editing the book, but why didn't they do this before publishing it? Come on! Although the book does contain some Android examples there are very few. Kotlin in Action is a significantly higher quality book, in which I saw not a single copy error. It also contains Android examples and so I heartily recommend that as an alternative.

This is probably the worst book for anyone starting out with Android development and Kotlin. The book is essentially a long list of loosely related details that might come up when working in Kotlin. Maybe there could have been a place for it as reference, but then of course it is already outdated. The one and only project - if one wants to call it that - starts on page 338 and assumes that one has read through the encyclopedic style of some hundred mini-topics. At that pint one then gets to type in reams of xml as the books doesn’t get into layout or other Android Studio related issues and any explanations from this point on are extremely brief or non-existing. Just thoughtless and horrible.
