是否BroadcastReceiver.onReceive总是在UI线程中运行？ [英] Does BroadcastReceiver.onReceive always run in the UI thread?

问题描述

在我的应用程序，创建自定义的BroadcastReceiver 并通过 Context.registerReceiver 注册到我的手动语境。我也有一个的AsyncTask 是通过 Context.sendBroadcast 调度通知-意图。的意图是从非UI工作者线程发送，但似乎 BroadcastReceiver.onReceive （接收所述的Intent）总是在UI线程中运行（这是为我好）。这是保证，我不应该依赖呢？

解决方案

  

是否BroadcastReceiver.onReceive总是在UI线程中运行？

是的。

in my App, I create a custom BroadcastReceiver and register it to my Context manually via Context.registerReceiver. I also have an AsyncTask that dispatches notifier-Intents via Context.sendBroadcast. The intents are sent from a non-UI worker thread, but it seems that BroadcastReceiver.onReceive (which receives said Intents) always runs in the UI thread (which is good for me). Is this guaranteed or should I not rely on that?
