Kotlin Programming By Example

By: Iyanu Adelekan

Overview of this book

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.

Building the Messenger Android App – Part II

In the previous chapter, we went full steam ahead with the development of the Messenger Android application. By doing so, we examined both Kotlin and Android application development in depth. We explored the Model-View-Presenter (MVP) pattern and how to use it to build powerful and fully functional Android applications. In addition to this, we covered the basics of Reactive programming and learned how to use RxJava and RxAndroid in our applications. We also learned about some of the available means by which we can communicate with a remote server. We learned about OkHttp and Retrofit, and then went one step further by implementing a fully functional Retrofit service to facilitate communication with the messenger API that we made in Chapter 4, Designing and Implementing the Messenger Backend with Spring Boot 2.0. Putting all this...
