java.lang.RuntimeException in kotlin

Question

I cannot print simple hello world script in kotlin. I connected my mobile phone. Although I enabled usb debugging, I got this error :

java.lang.RuntimeException

here is my code:

fun main() { println("hellooo") }

Answer 1

You can Use Log like this. (It's quit good in android)

Log.d("TAG", "hellooo")
Log.i("TAG", "hellooo")
Log.w("TAG", "hellooo")
Log.e("TAG", "hellooo")

But you also can use print and println in kotlin

print("hellooo")
println("hellooo")

Check for is there any other error.
