Modern Android App Development with Kotlin

Kotlin for Programmers

This module is for anyone who is looking to build their own Android applications. Ever since Google announced that Kotlin is the language of choice for Android development, Kotlin has become increasingly popular.

In this module, we’ll take a hands-on and project-based approach to develop Android applications. We’ll work with the most common tools that Android developers use every day, including Kotlin, Groovy, and XML. As we continue to learn, we’ll build a fully-functional Travel Blog Application that will be a great addition to our portfolio.

By the end of this module, we’ll have tangible experience in building an Android application and we’ll be ready to build even more complex projects.
