如果我有一个扩展的内部类的BroadcastReceiver 在我的服务类，我应该关心的同步，当在的BroadcastReceiver 类读取/从服务类写入对象？ 或者换用另一种方式：是 BroadacstReceiver 的的onReceive（）方法的一个额外的线程启动

If I have an inner class that extends BroadcastReceiver within my Service class, should I care about synchronization, when the BroadcastReceiver class reads/writes to objects from the Service class? Or to put it in another way: Are BroadacstReceiver's onReceive() Methods started in an extra thread?

推荐答案

本的onReceive（）方法总是被调用在主线程（也称为UI线程），除非你要求它被安排在使用registerReceiver（）的变体不同的线程：

The onReceive() method is always called on the main thread (which is also referred to as "UI thread"), unless you requested it to be scheduled on a different thread using the registerReceiver() variant:

Context.registerReceiver(BroadcastReceiver receiver, IntentFilter filter, String broadcastPermission, Handler scheduler)
