by allowing execution to be suspended and resumed. Coroutines are well-suited for implementing familiar program components such as cooperative tasks, exceptions, event loops, iterators, infinite lists and pipes.
首先保证创建了kotlin项目,然后,两个步骤: 1. 加入dependency,在 build.gradle(:app)中,加入 implementation 'org.jetbrains.kotlinx:kotlinx-coroutines-android:1.3.9' 2. 在kotlin文件中: import kotlinx.coroutines.*
这个库是没有包含在标准库中,要想使用它必须导入相应的依赖。 Maven <repository> <id>central</id> <url>http://jcenter.bintray.com</url> </repository> 1. 2. 3. 4. <dependency> <groupId>org.jetbrains.kotlinx</groupId> <artifactId>kotlinx-coroutines-core</artifactId> <version>0.18</vers...
<artifactId>kotlinx-coroutines-core</artifactId> <version>0.25.0</version> </dependency> 1. 2. 3. 4. 5. 然后直接上代码,先把官网上最简单的Hello world抄过来看看: fun main(args: Array<String>) { launch { // 开启协程 delay(1000L) // 阻塞协程,只能在协程里调用 println("World!") } ...
A lightweight image loading library for Android backed by Kotlin Coroutines. Optimal: Pixel performs optimizations with memory & disk caching, downsampling the image in memory by image view size (pixel by pixel), re-using Bitmaps, automatically pause/cancel requests (Signature requests), and more...

Add the dependency in the application build.gradle using Groovy dependencies { def utilsVersion = "2.2.10" // or check the latest from jitpack //biometrics implementation "com.github.FunkyMuse.KAHelpers:biometrics:$utilsVersion" //coroutines implementation "com.github.FunkyMuse.KAHelpers:coroutine...
dependencyResolutionManagement { repositories { google mavenCentral } } rootProject.name ="My_Application" include(":androidApp") include(":shared") 会发现主项目只include了androidApp和shared这两个子项目,因为这两个项目是Gradle项目,那么iOS的项目如何引用呢?我们摘抄一段官网的原文: ...
Module with the Main dispatcher is missing.Add dependency providing the Main dispatcher, e.g. 'kotlinx-coroutines-android所以上面withContext里面的代码就没有执行到了。 那么这里的MainDispatcher是什么呢?原来是在调用withContext来切换线程的时候,会用到类MainCoroutineDispatcher。这个类是个抽象类,会经过Main...
最终调试发现,果然这里runSafely里面catch住了一个exception,异常信息如下:Module with the Main dispatcher is missing.Add dependency providing the Main dispatcher, e.g. 'kotlinx-coroutines-android所以上面withContext里面的代码就没有执行到了。 那么这里的MainDispatcher是什么呢?原来是在调用withContext来切换线程...
