One of the first things you’ll notice is the extra parameter to the function — theContinuation. It forms the entire foundation of coroutines, and it is the most important thing by which suspendable functions are different from regular ones. Continuations allow functions to work in the suspende...
in particular,on mobile devices where resources are limited. Kotlin has simplified the way you can write code improving your productivity with a new programming paradigm,enhancing object-oriented and functional programming with with simple,powerful and new constructs. Coroutines are one of these!
Reactive programming uses a similar kind of approach to handle streams of data as the Kotlin coroutine channel. Like channels, reactive programming hasobservableswith data sources that emit items and should be observed. Then you also have theobserver, which is basically a consumer of items emitted...
本文属于合辑:https://github.com/mengdd/KotlinTutorials 协程的取消 取消的意义: 避免资源浪费, 以及多余操作带来的问题. 基本特性: cancel scope的时候会cancel其中的所有child coroutines. 一旦取消一个scope, 你将不能再在其中launch新的coroutine.
Coroutines概念 Coroutines(协程), 计算机程序组件, 通过允许任务挂起和恢复执行, 来支持非抢占式的多任务. (见Wiki). 协程主要是为了异步, 非阻塞的代码. 这个概念并不是Kotlin特有的, Go, Python等多个语言中都有支持. Kotlin Coroutines Kotlin中用协程来做异步和非阻塞任务, 主要优点是代码可读性好, 不用...
Activity/Fragment & Coroutines 在Android中, 可以把一个屏幕(Activity/Fragment)和一个CoroutineScope关联, 这样在Activity或Fragment生命周期结束的时候, 可以取消这个scope下的所有协程, 好避免协程泄漏. 利用CoroutineScope来做这件事有两种方法: 创建一个CoroutineScope对象和activity的生命周期绑定, 或者让activity实...

如果一个coroutine抛出了异常, 它将会把这个exception向上抛给它的parent, 它的parent会做以下三件事情: 取消其他所有的children. 取消自己. 把exception继续向上传递. 这是默认的异常处理关系, 取消是双向的, child会取消parent, parent会取消所有child.
