Did you know you could run your Kotlin code by simply supplying a top-level main function... even in Android Studio?

[StudyAndChillSounds]

Just learning Kotlin and I had trouble with just the code trying to run through my virtual device and this simple tip helped me run just my function so I can see my output. Thank you!

Thank you so muck. I was just looking for that topic on my pc for quite some days. Love from India.

Great tip!
The only disappointing thing this, for Android Studio it might be slow, because it rebuilds the whole project :)

Great! This what I was looking for, except for a question: can I run that simple main program on the Android device? Through adb I guess? Or is it already running on a connected device without anything else special to do?

Cool tip! By the way, there is a live template to generate a main function for you

you can just type "main" + enter
or "main0" + enter if you want the args parameter (args is not required on kotlin >= 1.3)

I tried following Kotlin tutorials in IntelliJ but it has no colors.xml or recycler view.
