ADB shell dumpsysactivitybroadcasts打印broadcasts的更具体信息。 包括三个项目
ReceiverList//注册的广播接收列表historical broadcasts [ foreground ] ://前台广播历史记录historical broadcasts [ background ] 3360
intentfilterintentfilter=newintentfilter (； intent filter.addaction (wangji cong.broadcast.test )； 注册器接收程序(newbroadcastreceiver () Overridepublicvoidonreceive )上下文上下文，Intent intent ) {toast.maketetent} } Intent intent=new Intent (； intent.set action (wangji cong.broadcast.test )； intent.setflags (intent.flag _ from _ background； 发送广播(英特尔)； 运行此接口后，打印dumpsys activity broadcasts信息。 如下所示。

通过dump broadcasts信息可以总结系统发送广播和处理的过程。
