Hello all.
How do I call a suspend function in Application.kt?
I have a suspend fun and when I call it, an error appears forcing to change the main function to suspend. And if I do that, I can't start the application.

if you are using coroutines in your app, it is a good practise to start coroutine fron the main function because it incorporates the coroutine and the dispatcher can be reused.
Try:

suspend fun main() = withContext(Dispatchers.Default) {
    // put your main's stack here
    // here you can call suspend funs 
    // and thread main is using when suspended 
    // other coroutine can work on it 
    // environment is reusable
}

Thanks @Animesh Sahu, but the Ktor does not accept susped fun main. But the Application.module inherits CoroutineScope, so just do
launch {asynchronous fun}

@Rodrigo Silva what do you mean?

It worked that way. The way you said, suspend fun main, ktor doesn't accept.
