README

kotlinx.coroutines

official JetBrains project GitHub license Download

Library support for Kotlin coroutines with multiplatform support. This is a companion version for Kotlin 1.4.0 release.

suspend fun main() = coroutineScope {
    launch { 
       delay(1000)
       println("Kotlin Coroutines World!") 
    }
    println("Hello")
}

Modules

Documentation

Using in your projects

The libraries are published to kotlinx bintray repository, linked to JCenter and pushed to Maven Central.

Maven

Add dependencies (you can also add other modules that you need):

<dependency>
    <groupId>org.jetbrains.kotlinx</groupId>
    <artifactId>kotlinx-coroutines-core</artifactId>
    <version>1.3.9</version>
</dependency>

And make sure that you use the latest Kotlin version:

<properties>
    <kotlin.version>1.4.0</kotlin.version>
</properties>

Gradle

Add dependencies (you can also add other modules that you need):

dependencies {
    implementation 'org.jetbrains.kotlinx:kotlinx-coroutines-core:1.3.9'
}

And make sure that you use the latest Kotlin version:

buildscript {
    ext.kotlin_version = '1.4.0'
}

Make sure that you have either jcenter() or mavenCentral() in the list of repositories:

repository {
    jcenter()
}

Gradle Kotlin DSL

Add dependencies (you can also add other modules that you need):

dependencies {
    implementation("org.jetbrains.kotlinx:kotlinx-coroutines-core:1.3.9")
}

And make sure that you use the latest Kotlin version:

plugins {
    kotlin("jvm") version "1.4.0"
}

Make sure that you have either jcenter() or mavenCentral() in the list of repositories.

Multiplatform

Core modules of kotlinx.coroutines are also available for Kotlin/JS and Kotlin/Native. In common code that should get compiled for different platforms, you can add dependency to kotlinx-coroutines-core right to the commonMain source set:

commonMain {
    dependencies {
        implementation("org.jetbrains.kotlinx:kotlinx-coroutines-core:1.3.9")
    }
}

Android

Add [kotlinx-coroutines-android](ui/kotlinx-coroutines-android) module as dependency when using kotlinx.coroutines on Android:

implementation 'org.jetbrains.kotlinx:kotlinx-coroutines-android:1.3.9'

This gives you access to Android Dispatchers.Main coroutine dispatcher and also makes sure that in case of crashed coroutine with unhandled exception this exception is logged before crashing Android application, similarly to the way uncaught exceptions in threads are handled by Android runtime.

R8 and ProGuard

R8 and ProGuard rules are bundled into the [kotlinx-coroutines-android](ui/kotlinx-coroutines-android) module. For more details see ["Optimization" section for Android](ui/kotlinx-coroutines-android/README.md#optimization).

JS

Kotlin/JS version of kotlinx.coroutines is published as kotlinx-coroutines-core-js (follow the link to get the dependency declaration snippet).

You can also use kotlinx-coroutines-core package via NPM.

Native

Kotlin/Native version of kotlinx.coroutines is published as kotlinx-coroutines-core-native (follow the link to get the dependency declaration snippet).

Only single-threaded code (JS-style) on Kotlin/Native is currently supported. Kotlin/Native supports only Gradle version 4.10 and you need to enable Gradle metadata in your settings.gradle file:

enableFeaturePreview('GRADLE_METADATA')

Since Kotlin/Native does not generally provide binary compatibility between versions, you should use the same version of Kotlin/Native compiler as was used to build kotlinx.coroutines.
