Hey people, after each clean of the project I’m getting a dozen of ‘unresolved reference` errors pointing to

apply plugin: 'kotlin'

library-module in android studio. After second build everything is ok, and each following build, however building after clean produces errors. I gotta feeling that classes are not generated at compile time, however, android studio does not show any error in the editor and “unresolved” classes can be navigated without problems. There is one question on SO with similar problem, but apparently, new version fixed this: https://stackoverflow.com/questions/35798993/unresolved-reference-kotlin-needs-2-builds-after-clean-to-pick-up-code-when-usi I’m using

apply plugin: 'kotlin-kapt'

for dagger, parceler and requery processing.

ext.kotlin_version = '1.1.3-2

Pardon my ignorance, but who is Jake Wharton? It looks like he did some presentations about Kotlin, but could someone explain?

That’s sort of the basic idea, but it can start to get pretty complicated when you need to restore state, but there are some libraries out there that already help with that kind of application structure. Conductor by Blueline Labs is one example.

🤔 humm… looks interesting but I think it will not solve my problem… I need to validate stuff… like if the email EditText has a valid email and in case of error set the error in the TextInputLayout…

A upgraded AS to 3.0 Beta 1 and my Kotilin plugin to 1.2-M2-release-Studio3.0-1 and changed my Kotlin version in gradle to 1.2-M2. However, I get an event saying "Outdated Kotlin Runtime, you version of Kotlin runtime in 'kotlin-stdlib-1.2-M1"..." . Any idea what other config I need to update?

i think it has something to do with

addToBackStack

because if i change the code so its always replacing the fragment (overridden the

onBackPressed

method) then its fine, real weird

Hello guys. Does Kotlin support lazy init variable with arguments ? In other words is it possible to simplify this construct ?

object Utils {
        private var testDevices: Array<String>? = null

        private fun getTestDevices(context: Context): Array<String> {
            return testDevices ?: context.resources.getStringArray(R.array.testDevices)
        }
    }

Hey ya, I have some resources that I'd like to put in my application. They are like 500 items and every item has 3 properties (a, b, c). My question is: should I use Room (SQLITE) or Xml Resources? I want to know which one is better in performance/storage. Anyway, they will need to be a local resource.

We tend to stick to Android topics related directly or indirectly to Kotlin as otherwise the channel would devolve into basically just a general Android chat which quickly becomes overwhelming.

where do you keep your dagger components when using kotlin? member of your Application class? standalone var?
