Hi. I am going through the Kotlin for Android Developers book and I got stuck in chapter 21. When I try to run the app, I can just see an empty activity and the code which should get the forecast data from database or from the web service never executes. It never even gets to the constructor of the RequestForecastCommand nor its execute() function. The debugger never gets there, the logs also never get printed. It's pretty weird, any clue what the problem is? This happens both with my and with the original version of the sample app from the author's GitHub so I assume it SHOULD work, despite the fact I am a Kotlin beginner I dare to say it actually looks like some Kotlin bug, but I'd be happy if I was mistaken. Thanks for any help 🙂
