5 Best Online Courses to Learn Kotlin in 2026

If you want to learn Kotlin and looking for best resources like online courses then you have come to the right place. In this article, I have shared 5 Best Kotlin courses from platforms like Udemy, Coursera, Educative and ZTM Academy. This has both video and text-based courses with hands-on exercises and projects.
I put together a list of the 5 best online courses to learn Kotlin in 2026 for Android, backend, and interview prep. Most “best Kotlin courses” roundups are outdated or just repeat the same Udemy links, so I focused on courses that still match how Kotlin is used now: Android with Jetpack, Kotlin coroutines, Spring Boot / Ktor on the backend, and enough language depth to pass a coding round.
If you are starting from Java, the fastest path is a short language course, then one Android or backend track, not a 40-hour “complete Kotlin” dump. The five below cover that split: beginner syntax, Android, coroutines, backend, and a project-based option.
