Accessing UI thread handler from a service

Question

I am trying some thing new on Android for which I need to access the handler of the UI thread.

I know the following:

1. The UI thread has its own handler

Answer 1

In kotlin thats how you can do it

Let say if you want to show Toast message from service

val handler = Handler(Looper.getMainLooper())
handler.post {
   Toast.makeText(context, "This is my message",Toast.LENGTH_LONG).show()
}
