You are the most straightforward explaining this. Thank you.

[MrJasonSnell]

you can also one-liner it instead of declaring "val intent" by simply using the line: startActivity(Intent(this, Main2Activity::class.java))

Hi,
I am getting this error:
None of the following functions can be called with the arguments supplied.
<init>(Context!, Class<*>!) defined in android.content.Intent
<init>(String!, Uri!) defined in android.content.Intent
