Handler() is deprecated

Issue

I am trying to update a seekbar every second in background using Kotlin & Coroutines but It says Handler() is deprecated use it with looper and i am confused how to use handler, looper and kotlin coroutines

The code i tried to make it work

val myHandler: Handler = Handler()
myHandler.postAtTime(asyncSeekBar(), 1000)

Here showing Handler() is deprecated

asyncSeekBar()

private fun asyncsSeekBar() {
        CoroutineScope(Default).launch {
            updateSeekBar()
        }
    }

but asyncSeekBar should be Runnable therefore showing and error

Type mismatch. Required: Runnable Found: Unit

If there is any other way of doing it with more simpler way, please suggest

Solution

You can use LifecycleScope for this to run every second:

lifecycleScope.launch {
    while (true) {
        delay(1000)
        updateSeekBar()
    }
}
