I have just finished the Treehouse's Kotlin for Java developer course. Now reading the reference docs. I plan to switch full time to Kotlin for my future Android app. 🙂

sudhirkhanger: I’m doing the same thing 😁 . I converted some of old apps to Kotlin as well. It made learning Kotlin easier.

It was a good introduction. I am a still a bit confused. I will go over reference once. May be I will try hhariri's beginner and advanced courses.

I am taking a slightly different approach. I convert one class from Java to Kotlin using the plugin, and then, I convert rest of the classes on my own. So, if I can’t figure out something, I refer to the converted class or I ask here on the Slack group.

That's an excellent approach. I am working on app from scratch. I suppose I will make a lot of mistakes but oh well.

Most of the things I need, I find on stackoverflow or kotlin docs. One thing I do is, I create a class called Test.java. Anytime I know to do something in java and not kotlin, I just type that out in Java and convert it. And then I see how it converts it and do the same from next time.
