Fantastic course that takes you from beginner to advanced in Kotlin for Android development with clear explanations and hands-on projects.
By Andrei Miroshnichenko on 5/26/2025
Quite a good introductory course. However, this course does not cover all the necessary concepts of the language even for Junior (for example, Exceptions)
By Richard Tomlinson on 1/14/2025
This course is misnamed - it is not about Android App Development. It uses Android Studio but never builds an actual app. It introduces Kotlin for someone who doesn't know programming so if you have ever used Java or other languages you will get bored and skip lots of content. It claims to cover all concepts of OOP but never discusses polymorphism and doesn't explain why you might use an interface, for example.

absolut gut geeignet
By Mark Tilton on 3/26/2022
Great intro course for a beginner (me). Launch the lessons, pause and follow the steps while you code along with the lesson. For me, that meant a 12 minute tutorial took about 30 minutes. But it gets you coding. I am still struggling on putting it together, the "why" isn't clicking and I don't understand how it ties together to produce a product.

This course is well segmented and reasonably paced. The concepts are explained thoroughly, which is exactly what a beginner needs. The audio quality is excellent and on top of that, the narrator is a joy to listen to.

Amazing course, not only by the content but the way the instructor teaches. I must say that up to this date i havent found better instructor in Udemy (and i took a LOT of courses). Really looking forward for the release of the new course, covering Android development with Kotlin
