how to wait for coroutine in non-suspend function?

fun f () {
  val result = async { ktor-client-function... return@async 1 }
  return result
}

runBlocking , not that I recommend it

[allan.conda]

your code doesn’t make sense, you want to run async but wait it from non-suspend function.

[allan.conda]

async is useless in your example

[Ifvwm]

because I use Ktor, and its function need to call in coroutine, so I use async to contain it

[allan.conda]

ok, runBlocking has the scope. I guess you were just using async to illustrate what you want

[albertosh]

Why not “moving the asynchronicity upwards”?
i.e. make your f function suspended and do the runBlocking at the beginning of your program

the original question is I use Glide in FileAdapter for a ListView, and in that Glide.load(url), the url is a redirect url, I need use Glide.load(httpclient.get(url)), but httpclient need to call in a suspend function, and FileAdapter.getView isn't a suspend function, how I can call ktor's httpclient in it?

[allan.conda]

load it from a scope

[allan.conda]

viewModelScope, lifecycleScope, fragmentLifecycleScope, viewLifecycleScope, whatever

[allan.conda]

makes sure you don’t leak it

[Ifvwm]

load what from a scop?

[Ifvwm]

scope.launch { Glide.load... } in getView?

[allan.conda]

yep

[allan.conda]

You’ll get NetworkOnMainThreadException anyway if you run okhttp from the main thread

[allan.conda]

Glide should be handling redirect URLs properly as well if client is configured
