Kotlin is expressive, concise, and powerful. It also ensures seamless interoperability with existing Android languages like Java and C++, which makes it easier to learn a new language for their most favored platform.
This book adopts a project-style approach, where we focus on teaching Android development by building three different Android Application, namely Building you Tic-Tac-Toe application, Developing your location based alarm and lastly 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 as the difficulty level grows steadily, in line with applications covered in later chapters.
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.
