You can use Kotlin coroutines like this. Declare the countdown job

private lateinit var textChangeCountDownJob: Job

And then onQueryTextChange:

    override fun onQueryTextChange(newText: String): Boolean {

        if(::textChangeCountDownJob.isInitialized)
            textChangeCountDownJob.cancel()

        textChangeCountDownJob = launch(UI) {
            delay(800)
        }

        return false
    }
