Hi! I just launched Kotlin Kōans, an app to help developers learn Kotlin through a series of 40+ short coding challenges (credits for the content go to Jetbrains). If you're in the process of learning Kotlin, take a look!

Play store: https://play.google.com/store/apps/details?id=me.vickychijwani.kotlinkoans
Demo: http://i.imgur.com/UTmcU39.gifv
Code: https://github.com/vickychijwani/kotlin-koans-android

Feedback is welcome 🙂

Looks awesome. Could you summarize how it works? How do you do the code highlighting, the code running, etc?

[vickyc]

Hey @kirillrakhman

[vickyc]

The code highlighting is done in a WebView via CodeFlask: https://github.com/kazzkiq/CodeFlask.js/

[vickyc]

To run the code I'm calling out to the same API used by Kotlin Koans on the web: https://try.kotlinlang.org

[vickyc]

That is also where I'm downloading the challenge description, code, etc. from

[vickyc]

Let me know if you have any other questions. Btw I've included a Github link above - feel free to dig into the code of course! 🙂

[kirillrakhman]

Thanks. I'm on mobile, that's why I'm asking.

[kirillrakhman]

Btw the UI looks really slick

[vickyc]

Thanks 😄. Yes, I am a bit of a UI nut 😛

[vivekneel]

Nice! But too much stuffs in the navigation drawer . 🙂

[vickyc]

@vivekneel well, that's just the list of challenges 😄. Do you have any suggestions in mind? 🙂

[vivekneel]

@vickyc how about making each category item intro, collections etc as expandable with some cool animation when it's expanded 😎

[vickyc]

@vivekneel Let me see if that's feasible to do with NavigationView from the design support library. I'll also have to see the UX implications of this - thanks!
