TRAINING COURSE OVERVIEW

Our Kotlin training course will focus on teaching Kotlin from beginner to an intermediate/advanced level.

Typically Kotlin is used for Development of Android Apps or Backend applications with Java.

This course will help delegates understand the pure Kotlin Language and Best practices for using it in anger. Delegates can choose to keep Labs as "vanilla" Kotlin, or to apply to Android or Java development.

In this course we will focus on practical Kotlin development. We will briefly go over the Kotlin language in the ways it is equivalent to Java. We will spend a bit of time introducing concepts that Kotlin provides that are not found in Java.

Following that, we will begin to learn Kotlin development by creating an Android application using all of the modern libraries and technologies that are necessary for a successful commercial application.

We will set up a strong foundation by putting in place an MVP architecture that is both flexible and scalable. We will use reactive programming (RxAndroid) to achieve the network communication on background threads. Interactions between the View and the Presenter will be done via RxBinding methods to further decouple the Presenter. Finally, we will be implementing unit testing for our presenters, as well as UI testing.

This will allow us to build an application that is scalable, and that allows for Continuous Integration and Continuous Delivery to be set up.

In addition to that, this methodology of development allows for large team collaboration using Git and a versioning system (GitHub). It will allow us to be adaptable and flexible and permit using Agile development methodologies like Scrum or Kanban.
