This one is not exactly related to Compose however I m havin kotlinlang #compose

This one is not exactly related to Compose, however, I'm having issues with the latest AS canary + collections. Canary 13 + Kotlin 1.4.0 = I can use the standard Kotlin

emptyList()

Canary 13 + Kotlin 1.4.10 = forces me to import

java.util.Collections.emptyList

, does not allow me to reference the standard one. (sorry, I do not know if this was happening in previous canary versions. I have just updated to Kotlin 1.4.10 to test alpha04) P.S.: I tested Kotlin 1.4.10 in stable AS and in IDEA, no issues there.

does not allow me to reference the standard one.

What do you mean? is it not building and show as unresolved?

Yes, it is not building. 1. Autocomplete suggests me to import Java collection (

java.util.Collections.emptyList

). 2. If I try to do

import kotlin.collections

manually, I get this error:

you cannot import package

it’s valid error

import kotlin.collections.* - this is valid syntax

and anyway emptyList() doesn’t require import, it imported by defaulk

Oh I totally missed the .*, you're right! I don't get the import error, but still does not recognize it...

However yes - that's exactly the problem. My existing code had no import because it should not be needed. However, now it's not recognizing it 😕 forces me to import

(brand new project created in latest Canary, using kotlin 1.4.10)

as usual in such cases “Invalidate caches and restart” 🤷

I have the same, also after invalidating caches and restart, but only in Android Studio and not in Idea
