I'm fighting Hamcrest matchers where

assertThat(list, IsIterableContainingInOrder.contains(anotherList))

doesn't make the compiler type resolver happy.

yeah, but if I have a view, which has an ID, but is not used in the activity, for example I need a Relative layout construct

@miha-x64 there's a KEEP in progress to add an option for it: https://github.com/Kotlin/KEEP/pull/33

Compiles fine, but either the files have tons of errors like this, or I can spam the keyboard and get 0 errors - each file behaves different.

I have a silly question. Various questions on SO and tutorials on the web suggest saving a listener interface in your

AsyncTask

to still keep a reference and publish progress to your fragment/activity/service/anything. Question stands, shouldn't it be

WeakReference

? I'd assume that ART does not garbage collect running threads and if your application is suddenly ended, keeping a hard reference to your context will prevent ART from garbage collecting it.

Is Gradle Kotlin Script compatible with Android Studio 2.4? I’m trying to use it, but even

buildscript

method is unavailable

I think I have it:

ext.kotlin_version = '1.1.2-4'

    repositories {
        maven { url '<https://maven.google.com>' }
        jcenter()
    }

from reddit: if you have gradle issue on AS 3.0 just bump kotlin plugin version to 1.1.2-4 in build.gradle

lot of official code samples for android available in kotlin on https://developer.android.com/samples but if you check some https://github.com/googlesamples/android-AutofillFramework/blob/master/kotlinApp/Application/src/main/java/com/example/android/autofillframework/app/LoginActivity.kt you will see lot of .!! is it ok?

but a guard statement which assigns to safe vals eliminates the issue

anyone having an issue with

kapt

and the android gradle plugin v3.0 ?

Has anyone had issues with 1.1.2 causing your test/androidTest compile steps failing due to unresolved refs of classes in main/variant source sets?

That's because you have imported your setting of a previous version of AS with Kotlin plugin Delete ~/Library/Application Support/AndroidStudioPreview3.0/Kotlin folder and the IDE will use the built in 1.1.2-4 version when creating a new project

I bought it when it was in early access, but if I'm not mistaken if you buy the physical book, you can get the ebook version for free

you mean something like

x?.let{} ?: run {}

?

I feel like if you need an else case for

let

then you don't need

let

at all, what you want is really the classic if-else

@lpirro Second best is Build Speed Improvements in android studio 3.0

Do you still need to specify the kotlin dependency in gradle with AS3.0?

anyone facing:

Unable to find method 'com.android.build.gradle.internal.variant.BaseVariantData.getOutputs()Ljava/util/List;'

in android studio 3 with the new gradle version?

Is it safe to use kotlin-stdlib-jre8 on Android?

can anybody help me how can i start ?

But on the other hand,

Crtl+Shift+Alt k

is gonna be missed

use both, no?

Hey, is it possible for an app to play sound "into" an active phone call?

question, i'm trying to learn kotlin for android (I'm a BRAND Spanking new mobile developer) How would I handle authentication against my rest end point?

Hi guys, i'm new with kotlin. do you have any kotlin libraries that should be noted or you usually use in your projects? i've seen Ravindra Kumar's repo, and wondering if there are any other interesing libraries i should aware of while developing Android with kotlin? cheers 🙂 https://github.com/ravidsrk/android-mvp-kotlin-starter

Hello everyone...um new at kotlin...wanna to learn it to develop android...how can I start it...!! Kindly help me with some tutorials link or helpful resources🙂

Hey everyone, I’m integrating Kotlin into a project using Java 8, AS 3.0. I intend on removing

@Data

lombok annotations and using Kotlin data classes instead. However, I’m getting

java.lang.ClassNotFoundException: kotlin.jvm.internal.Intrinsics

, which seems to suggest my Kotlin code isn’t being brought into my project. I have in the global `build.gradle`:

classpath "org.jetbrains.kotlin:kotlin-gradle-plugin:1.1.2-4"

and in my app module `build.gradle`:

apply plugin: 'kotlin-android'

Whoever developed mockito-kotlin is a god. Its so nice to initialize and setup a mock in one line:

val content: Draft = mock { on { baseline } doReturn 35 }

Coroutines vs Promises: differences, benefits of one over the other, etc? I haven't touched Kotlin much yet, so I'm curious if there are some more experienced voices who could weigh in...
