Hey guys is this an appropriate place to ask about potential issues with Kotlin on Android? 🤔 - I have a really bizzar issue that might be being caused by me but anyways… I’ve created a simple event dispatcher that’s lazy initialised like so

companion object {
        val instance by lazy { EventDispatcher() }
    }

and whenever I add anything to it and try to dispatch an event, I receive the following error
java.lang.NoClassDefFoundError: jonnothebonno.me.app.notifications.events.EventDispatcher$dispatchEvent$1

The weird thing is, this only appears to happen on older mobiles. Works perfect on my pixel but crashes on my nexus 5.

I’m using Kotlin 1.1.1 and gradle 2.3.0

Does this happens on debug builds only?

[jonnothebonno]

Hey Louis. No it happens on both debug and release builds. 😰

[louiscad]

@jonnothebonno Can you show me the code of EventDispatcher? Consider private message if it can't be public

[jonnothebonno]

Yeah sure, one moment.

[louiscad]

@jonnothebonno Haha, simple. Just add parenthesis around the lambda parameters

[louiscad]

You're calling some java 8 code. Adding parenthesis means destructuration, and this is from kotlin's stdlib, not java 8

[jonnothebonno]

omg really? thank you 🤣 stupid me

[louiscad]

@jonnothebonno Let me know if it worked fine

[jonnothebonno]

Will try it now!

[jonnothebonno]

it worked! thank you so much 😄
