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.*

让我们来看⼀个例⼦,⼀个简化的 async() 函数(源自kotlinx.coroutines库): 下面贴上async的代码: public fun <T> async(context: kotlin.coroutines.experimental.CoroutineContext, start: kotlinx.coroutines.experimental.CoroutineStart, parent: kotlinx.coroutines.experimental.Job?, block: suspend kotlin...

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: ...

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...
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...
