广播接收组件生命周期 Broadcast receiver lifecycle
广播接收器是一个除了接收和响应广播通知以外啥也不做的组件。
A broadcast receiver is a component that does nothing but receive and react to broadcast announcements.
如果发送广播时设置了这个标志，那只会调用注册了的接收器——BroadcastReceiver组件不会被启动。
If set, when sending a broadcast only registered receivers will be called — no BroadcastReceiver components will be launched.
