I'm trying to access `Thread.currentThread()` from...

# multiplatform

[David Hart]

I'm trying to access Thread.currentThread() from a Kotlin Mobile Multiplatform project to check that I am in the main thread, but it doesn't seem accessible. Are my missing something? Is there another way?

There is no such a thing like Thread in common source set. But you can expect/actual.

[Kris Wong]

Thread is a Java API

[edenman]

expect fun isMainThread(): Boolean
actual fun isMainThread(): Boolean = Looper.getMainLooper() == Looper.myLooper()

[edenman]

(assuming you’ve got an android sourceset ofc)

Thanks for the answers!

If you're trying to do the same actual for iOS, it would be something like this

import platform.Foundation.NSThread

actual fun currentThreadName() = "iOS thread ${NSThread.currentThread()} is main: ${NSThread.isMainThread()}"
