Kotlin Coroutines and Delay

By  on  

Whenever I suspect that there's a timing conflict causing a problem with rendering and directives, I usually opt for a JavaScript setTimeout with a delay. The setTimeout code never makes it to production, but it does help me to understand if my code is the problem or if there's a timing conflict.

In working with Kotlin on Android, I've needed to employ the same technique. Kotlin obviously doesn't have a setTimeout, but it does have coroutines to achieve approximately the same effect.

To run an async coroutine with delay, you can use the following Kotlin code:

// Create an async coroutine
GlobalScope.launch {
    delay(1000)
    
    // Execute code to test functionality
}

The coroutine becomes async and the delay can be whatever amount of milliseconds you'd like!
