Build Android apps and learn the essentials of the popular Kotlin programming language and APIs. This book will teach you the key Kotlin skills and techniques important for creating your very own Android apps. Apart from introducing Kotlin programming, Learn Kotlin for Android Development stresses clean code principles and introduces object-oriented and functional programming as a starting point for developing Android apps. After reading and using this book, you'll have a foundation to take away and apply to your own Kotlin-based Android app development. You'll be able to write useful and efficient Kotlin-based apps for Android, using most of the features Kotlin as a language has to offer. What You Will LearnBuild your first Kotlin app that runs on Android Work with Kotlin classes and objects for Android Use constructs, loops, decisions, and scopes Carry out operations on data Master data containers, arrays, and collections Handle exceptions and access external libraries Who This Book Is For Very little programming experience is required: no prior knowledge of Kotlin needed.

Kotlin is a free and open-source general-purpose programming language that is mostly used to create Android apps. It was developed by JetBrains initially and later on picked up by Google as language of chioice for its Android platform. Over the past few years, Kotlin has become one of the most popular programming languages over Java Language and is used by more than 80% of Android apps developers. Kotlin is a statically typed, advanced programming language that compiles Kotlin code into Java byte-code and runs on a Java Virtual Machine (JVM). It can also be compiled to native executables and JavaScript source code. It is an object-oriented programming language that includes data types, operators, I/O comments, control statements, functions, classes, object expressions, and constructors, among other features. It is not a standalone programming language; rather, is an innovative manner of coding that runs on Java. Kotlin is a versatile language with some interesting and cool features like compatibility, low runtime, and efficient coding characteristics. The features that help Kotlin distinguish out from other languages are its reliability, tool support, and interoperability. It is a simplified version of Java that is much easier to deal with. Why Should You Learn Kotlin? The popularity of Kotlin is growing, and it will continue to do so in the coming years. Kotlin has always been, and will continue to be, a cutting-edge programming language that best meets the needs of real professionals. Many emerging fields, including mobile, online gaming, server-side, and cloud development, data science, and education, are progressively using Kotlin. All of this indicates that there is already a high demand for Kotlin developers, and that demand will continue to grow in the future. Furthermore, if you are looking to build native Android apps, Kotlin is the language that you should be using. In This Book Step by step approach to problem solving and skill development A quick run-through of the basic concepts, in the form of a "Crash Course" Advanced, hands-on core concepts, with a focus on real-world problems Industry level coding paradigm, practice-oriented explanatory approach Special emphasis on writing clean and optimized code, with additional chapters focused on coding methodology

Kotlin is expressive, concise, and powerful. It also ensures seamless interoperability with existing Android languages like JAVA and C++, which means that it's even easier for developers to use. This book adopts a project-style approach, where we focus on teaching Android development by building three different Android Application: a Tic-Tac-Toe application, a location- based alarm and a To-Do list application. The book begins by giving you a strong grasp of the Kotlin language and its APIs as a preliminary to building stunning applications for Android. You'll learn to set up an environment and as you progress through the chapters and the building of the different applications, the difficulty level will steadily grow. The book also introduces you to the Android Studio IDE, which plays an integral role in Android Development. It covers Kotlin's basic programming concepts such as functions, lambdas, properties, object-oriented code, safety aspects and type parameterization, testing, and concurrency, and helps you write Kotlin code to production. Finally, you'll be taken through the process of releasing your app on the Google Play Store. You will also be introduced to other app distribution channels such as Amazon App Store. As a bonus chapter, you will also learn how to use the Google Faces API to detect faces and add fun functionalities.
