is kapt3 compatible with gradle 3.3?

I seem to be getting unresolved reference errors while using databinding

Wait, never mind. Apparently needed to update to

'com.android.databinding:compiler:2.3.0'

Does Kotlin suports android... 1. Jack and Jill toolchain? 2. Incremental compilation? 3. Instant run?

@igor.wojda 1. Supported since 1.1.0 2. Supported, but limited with Jack enabled 3. Supported, but afaik with Jack this feature doesn’t work even with Java

Is this issue being tracked somewhere? https://discuss.kotlinlang.org/t/turn-off-code-generation-for-kotlin-android-extensions/1670/9

@okaymak found this one https://youtrack.jetbrains.com/issue/KT-12741

Kotlin Android Extensions question: If you have a view where you're importing IDs from multiple other views (so you have multiple synthetic property star-imports, basically), and two of those layouts define the same ID for two different views, you get an overload resolution ambiguity when you try to use it. Is there any way around this? I think you have to use the extensions with a star-import, so we can't even use a named import to get around the ambiguity

We are gradually migrating our codebase to Kotlin, so we use our Java robots in our Kotlin tests (eventually we will move all those robots to Kotlin, but for now they stay). All fine until you want to use a Kotlin robot in your Java test code. Has anyone used a Kotlin robot (basically any Kotlin test class) in their Java tests? How do you manage the cyclic dependency issue? I mean assemble Java Android test -> assemble Kotlin Android test -> assemble Java Android test

for the non-test code this is handled by Kotlin Gradle plugin, I wonder how they handle it. I read something about multi-phase compilation and that they stub everything, but I didn’t quite get it. How could one achieve the same thing for compiling tests?

@kevinmost actually you can use named import, something like

import kotlinx.android.synthetic.main.activity_kotlin.textView as myTextView

@javad Using Kotlin classes in Java tests should work normally, Kotlin compiler parses Java source files by itself so no cyclic dependencies here, Kotlin sources should be built first

@vyacheslav.gerasimov Don't forget to mention that they have to be properly annotated with

@Jvm*

annotations

How would you do that in the next project? (same answers)

Is it possible in osx android studio terminal to enable alt+left and alt+right shortcuts to jump words, like in normal terminal? Now it only prints [D

@zokipirlo sure. Just add

bind '"\e\e[D": backward-word'
bind '"\e\e[C": forward-word’

in your bash.profile

it’s gonna work regardless on the terminal (iTerm, Android Studio, or default Mac OS terminal app)

@jovmit thanks! it works

it always returns Array<out Any> in the zipper function

@User uploaded a file: Kotlin 1.1 has made me an instantly happier person

If I want to have a ViewHolder as separated class, how could I import the android extensions? Have to declare the library on the build file?

Or does the android extension work only when I have a Activity/ Fragment or some with context?

It works on my viewholder classes, I do itemView.myView (itemView is a property of the ViewHoder class)

the import is something like import kotlinx.android.synthetic.main.layout_name.view.*

But your viewholder are standalone classes?

yes

Just be aware the only Activities and Fragments cache the view lookups so if you do

itemView.myView

it is calling

itemView.findViewById()

every time (as posted a few days ago https://youtrack.jetbrains.com/issue/KT-10542)

Which sort of defeats part of the purpose of having a ViewHolder in the first place 😉
