Android Programming with Kotlin for Beginners Pdf Book Description:

Are you trying to start a career in Android programming, but haven’t found the right way in? Do you have a great idea for an app, but don’t know how to make it a reality? Or maybe you’re just frustrated that to learn Android, you must already know Kotlin. If so, then this book is for you. Android Programming with Kotlin for Beginners will be your guide to creating Android applications from scratch. We will introduce you to all the fundamental concepts of programming in an Android context, from the basics of Kotlin to working with the Android API. All examples are created within Android Studio, the official Android development environment, which helps supercharge your application development process. After this crash course, we’ll dive deeper into Android programming, and you’ll learn how to create applications with a professional-standard UI through fragments and store your user’s data with SQLite. In addition, you’ll see how to make your apps multilingual, draw on the screen with a finger, and work with graphics, sound, and animations too. By the end of this book, you’ll be ready to start building your own custom applications in Android and Kotlin.This book is for you if you are completely new to Kotlin, Android, or programming and want to make Android applications. This book also acts as a refresher for those who already have some basic experience of using Kotlin on Android to advance their knowledge and make fast progress through the early projects. Chapter 1, Getting Started with Android and Kotlin, welcomes you to the exciting world of Android and Kotlin. In this first chapter, we won’t waste any time before getting started developing Android apps.

We will look at what is so great about Android, what Android and Kotlin are, how they work and complement each other, and what that means to us as future developers. Moving on, we will set up the required software so that we can build and deploy a simple first app. Chapter 2, Kotlin, XML, and the UI Designer, discusses how, at this stage, we have a working Android development environment and we have built and deployed our first app. It is obvious, however, that code autogenerated by Android Studio is not going to make the next top-selling app on Google Play. We need to explore this autogenerated code so that we can begin to understand Android and then learn how to build on this useful template. Chapter 3, Exploring Android Studio and the Project Structure, takes us through creating and running two more Android projects. The purpose of these exercises is to explore Android Studio and the structure of Android projects more deeply. When we build our apps ready for deployment, the code and the resource files need to be packed away in the APK file – just as they are. Therefore, all the layout files and other resources, which we will be looking at soon, need to be in the correct structures. Fortunately, Android Studio handles this for us when we create a project from a template. However, we still need to know how to find and amend these files, how to add our own and sometimes remove the files created by Android Studio, and how the resource files are interlinked sometimes with each other and sometimes with the Kotlin code (that is, the autogenerated Kotlin code as well as our own). Along with understanding the composition of our projects, it will also be beneficial to make sure that we get the most from the emulator.
