the error log says "gradle sync failed: Cause: error in opening zip file"

I can not run single test in AS 3.0, I can not edit configuration for it

It is so annoying to run all tests just to check out put of one

but it is not about kotlin

Our tooling in terms of compatibility becomes joke

I would love to move to IntelliJ but then I have other problems with just opening android project

Hi guys, is there a method like

new Handler().postDelayed(new Runnable().......)

in

Kotlin

, what is best approach to do this in Kotlin

Do you want to create runnable?

.postDelayed( Runnable { ... } )

should work.

@karelpeeters I did this , but getting

Unresolved Refrence Error

also tried with

Handler.postDelayed(Runnable {})

@sherwani uploaded a file:

once you get the unresolved reference, just do alt + enter and the IDE will auto import it for you

Help needed please 🙏 https://kotlinlang.slack.com/archives/C0B8M7BUY/p1508932216000183

Hey guys! Sorry for asking maybe a stupid question, but I'm migrating a personal project to Kotlin and I'm trying to figure out if I can, in a generic way, include the dagger component's

inject

as an extension function from the class that is to be Injected. I'm thinking of something like this

abstract class Injectable <T : SomeBaseComponent> {
    
    abstract fun T.inject(activity: Injectable)
    
}

but the more I think about it, 1. the less sense it makes to be possible to do (especially when you're adding a method to an existing interface) 2. making the

T

method abstract makes the class abstract (??) 3. I would actually want sublasses of

Injectable

to be passed, not the bass class itself. Anything that can be done close to that maybe? 🤔

have a look at the dagger-android stuff it does a pretty decent job of using base types to handle injection

I have a coroutine question.

How can I call it to get

1

? Then, I want to call it again to get

2

, etc. How to do that?

oh

are you looking for

.next()

?

infinite.next()

gives an error: unresolved reference

it's a

Sequence

, it doesn't have

next()

, you can use anything for a sequence: https://kotlinlang.org/api/latest/jvm/stdlib/kotlin.sequences/-sequence/index.html

or you can use it in a for loop, or you can get an iterator from it and use

.next()

on that:

infinite.iterator()

For the second call I'd like to get

[6, 7, 8, 9, 10]

. How to do that?

But then I need to keep track how many to drop. Is there a simpler way? I want to simply get the next elements. Actually, I want to process the elems yielded back one by one.

You want a for loop.

doesn't that defeat the purpose of lazy sequences

you can just compute it each iteration of the for loop
