How to use Hour, minutes & sec in delay kotlin

Question

I want to use delay in my launch function. I always use xxxL value for delay. Is there any function to convert seconds, minutes & hours . For example

For 30 second

delay(30)

For 1 minute

delay(1)

For 2 Hour

delay(2)

It's so much confusing to multiple by value. Thanks

I tried from Delay with Duration, but I am getting error in here

delay(Duration(1.minutes))

imports

import kotlinx.coroutines.delay
import kotlinx.coroutines.launch
import kotlin.time.Duration
import kotlin.time.Duration.Companion.minutes

Error

I don't know what I am doing wrong in here.

UPDATE

which one should I use to import?

Answer 1

You can also use delay(1.minutes).

Required import: kotlin.time.Duration.Companion.minutes

Answer 2

The delay() function can take a Long value when you wants to delay by a certain amount of milliseconds or any Duration.

Kotlin provides helpers to create duration given any number. You can create them with special extension properties from the Duration object.

To create duration :

val second: Duration = 1.seconds
val duration: Duration = 2.4.minutes

You can use the delay function with it

scope.launch {
    delay(seconds)
    delay(duration)
}

A duration can be converted back to milliseconds in Long with:

val oneSecondInMillis: Long = seconds.inWholeMilliseconds
