I'd been wanting to learn Kotlin for years, following Antonio, so I didn't hesitate for a second to join this course. Antonio dominates Kotlin in an extraordinary way, and best of all: he knows how to transmit knowledge!

I recommend 100% doing any type of workshop that Antonio publishes :)

- Alejandro Ramírez, Sportfriends CEO & Android Developer

I could simply say "100% recommendable" but I would not express everything that this workshop means... I have learned in a very short time how to build Apps in Kotlin, very well explained with practice included, and several resources to further investigate.

Great idea to do this online course that gives the opportunity to learn directly from a specialist.

Your Instructor


Antonio Leiva
Antonio Leiva

Since I discovered Kotlin in 2015, I've spent a lot of time learning how to take the most out of it to develop Android Apps.

My goal is to show you this knowledge, how to use Kotlin in an Android environment with my training so you can improve your productivity, overcome the limits of Java and stand out as a developer by creating modern, simple and functional code.


Content details

Want to know more? Here's a detail of the content of the course.

1. Introduction

In this first module, I'll introduce the course, how it'll work, and a first introduction about Kotlin. You'll also create your first Android project using Kotlin from scratch.

2. Basic concepts - Variables, Functions and String templates

Every language has a basis that you need to master before going deeper.

You'll do here a small review about all these concepts, and the difference they have when compared to Java. This will be the start of great journey into Kotlin!

3. Classes, Properties and interfaces

The ABC of object oriented programming. You'll see everything related to these concepts, and how they'll help us save a lot of code and be more productive.

4. Discovering the magic of Kotlin

There are many features in Kotlin that seem almost magic when we come from Java. In this module you'll discover some of them.

We'll talk about extension functions, flow control (and the awesome when), Kotlin Android Extensions and Enums.

5. Lambdas: welcome to the functional world

You may know about them if you use Java 8, but lambdas in Kotlin are really important. From simple features as simple as a callback, to other more complex ones such as DSLs creation, lambdas will be in your every day from now on.

And this is great, because they'll Y esto es algo genial, ya que nos acercan a la programación funcional y abren un mundo infinito de posibilidades.

6. Bringing your App to life

We keep making our sample App awesome, and now we'll give some content to the RecyclerView we added some modules ago.

In order to do this, we'll learn concepts like property delegation, Kotlin collections, ranges and objects.

7. Anko

This library that the Kotlin team created thinking of Android Developers hides amazing secrets. Not only because of how much it'll help you in your work, but also because you can learn a lot by reading the source code.

Here we'll see and use some of these features.

8. Building the detail Activity

We already have our main Activity working, but it'll be great to implement a more complete App, right?

Well in this module we'll get into it, and by the way you'll learn about nullity and sealed classes.

9. What's new in Kotlin 1.1

Although we'll have already seen some details about the new version of Kotlin throughout the course, here I'll talk about two new features that are just great: type aliases and co-routines.

Do not miss the latest in Kotlin!

10. Extras

With Kotlin you can keep working with the same tools that were using until Know in Java, but taking the most out of the language.

In this latest module, I'll show you a simple example about how to test your Apps by using the same tools you were using until now (JUnit and Mockito), and how you can keep using Dagger for dependency injection.

We won't dive deep into these concepts (they both could have their own course), but if you know about them, it'll be easy for you to do the transition to use them in Kotlin.

Essential course for those who want to land on this new language supported by Google to develop Android Apps. And more if the trainer is the write of one of the books advised by Google to learn about this language.

Congratulations to Antonio Leiva, for his natural vocation to teach with such dedication and enthusiasm.

Kotlin makes everything cooler. But the fact that the course is so good is not only due to the language, but also to the excellent teacher and content that is covered here.

Super recommended!

A very practical course where in a short time you can learn all the benefits of Kotlin and get the bases to start putting it into practice.

Highly recommend.

- Alberto Montes de Oca, Apps developer

The course fully met my expectations. The app that is developed in the course allows to focus solely and exclusively on Kotlin features. You will not waste time doing layouts or incorporating libraries that wouldn't add any value.

Despite my knowledge of Kotlin, I had no problem in following the pace marked by the course.

I totally recommend this course if you are tired of the limitations of java.

- Joaquim Puyo, Android Developer, Atos Wordline

A great introductory course to Kotlin. You can tell that Antonio knows a lot about Kotlin. The way the content is organized is very enjoyable, to the point that time flies when you are on it.

Highly recommended, especially for all those who come from the Java world, as you realize the amount of unnecessary code you have been writing and now you can save.
