Well, it never crashed. Instead, coroutines framework simply died. Well, I’m not sure that the verb “died” is the correct one in this case, but I haven’t seen anything like that in the past. At some point, after a chunk of application’s memory was leaked, coroutines simply sto...
launch是将CoroutineContext作为第一个参数,这个参数值默认为代表一个CommonPool线程池类的DefaultDispatcher,这个线程池类根据当前CPU处理器总数创建一个带有Executors的CoroutineContext。完整代码在这里。 launch是一种协程构建器,可以接受一个协程分配器CoroutineDispatcher,分配器实际上负责在单独的线程中运行代码。 我们可以...
so starting a coroutine with [Dispatchers.Unconfined] by [DEFAULT] is the same as using [UNDISPATCHED].** If coroutine [Job] is cancelled before it even had a chance to start executing, then it will not start its* execution at all, but will complete...
Executors.newScheduledThreadPool(10) .asCoroutineDispatcher().use { dispatcher -> GlobalScope.launch(dispatcher) { log(1) // 这里会默认继承父协程的调度器 val job = launch { log(2) delay(1000) log(3) "Hello" } log(4) val result = job.join() ...

换个角度看,KMP 产出的app.framework是一个基础共享层,iOS 原生代码依赖于这个库。从依赖关系上,我们无法直接调用 iOS App 源码中的CamerePreview。解决方法也不难,一般分两种: 把相关代码打包成一个独立模块,产出cameraview.freamework,让app依赖它。 iOS App 在初始化 app.framework 时,传入一个 lambda 到app用...
The coroutine that is created, but is not started yet, is represented by its initial continuation of type Continuation<Unit> that consists of its whole execution.As mentioned above, one of the driving requirements for coroutines is flexibility: we want to be able to support many existin...
