// kotlin kapt "com.android.databinding:compiler:2.2.0"

Hello everyone. Is it safe to use Kotlin 1.1.1 in Android project, or I should use 1.1.0?

yes

@aballano This issue should be fixed in 1.1.2 eap https://youtrack.jetbrains.com/issue/KT-12769

@vyacheslav.gerasimov Are you planning to support all the cases?

@mg6maciej @miha-x64 very interesting. So if i understand correctly each app has the same system classes but they get copied when one modifies them.

speaking of layouts i am curious whether someone else uses the kotlinx extension for accessing the xml layout views or is everone using butterknife/databinding or findViewById ?

@miha-x64 Could you share the most complex layout you have created with Anko? Did you hit any wall and had to go back to xml for any reason?

Can I use Android Studio to create a regular old java library or is it better to install classic IntelliJ separately for this?

How can I get Kotlin 1.1.2 EAP? I tried to update the Kotlin plugin but I keep getting an error.

correct it just works

@dg3feiko see here: https://github.com/Kotlin/kotlinx.coroutines/blob/master/ui/coroutines-guide-ui.md

Personally set up an Android 4.0 emulator with the smallest screen possible and 512MB of RAM only to make sure my app works on it, and to not slow down my computer

so basically

if (url?.contains("#") == false)

sure, Google hasn't embraced it, but they also haven't embraced the mile-high stack of libraries from Square and the like that we all use to make Android dev tolerable, anyway

data class

without a constructor param in Kotlin, possible?

is anyone using Buck (https://buckbuild.com/) instead of Gradle for their build in real production non-trivial apps?

There is also https://gitlab.com/arturbosch/detekt

Ah, wow… It’s a JetBrains annotation problem… 😐

it seems the support library resource annotation lints don’t work when used on a vararg param. user error or possible bug/feature request?

private fun View.popupMenu(@MenuRes vararg menuItems: Int): PopupMenu {
        return PopupMenu(this.context, this, Gravity.END, 0, R.style.AppTheme_Widget_PopupMenu_Overflow).apply {
            menuItems.forEach { inflate(it) }
            show()
        }
    }

just_like_that

so it's clear it's magic

There is also some docs about kapt https://kotlinlang.org/docs/reference/using-gradle.html#annotation-processing

when updating to 1.1.2 I can not compile my androidTest as any reference to the main source set is unresolved. seems related and a total reverse of what was this issue: https://youtrack.jetbrains.com/issue/KT-16897

@alexey.tsvetkov Just a thought: if

R.java

was converted to

R.kt

, would this make incremental compilation faster?

When

kotlin-android

is used, the tasks are not available during script evaluation. You can refer to

compileKotlin

in

project.afterEvaluate { compileKotlin }

. On the other hand if you want to set

suppressWarnings

for the whole project, you can just use

kotlinOptions

extension in

android

block.

android {
     kotlinOptions.suppressWarnings = true
}

@ben.bachhuber Never thought I would see another Bachhuber in here 👍

is anyone else having that problem?

I haven't run benchmarks but I'd expect that calculating MD5 and comparing them is faster than comparing all the bytes one by one
