如何查看Android系统当前发送了什么广播

前言：在开发的时候，我们有时想知道我们定义的广播是否成功发送，或者想知道做了某个操作，系统是否会发送广播，并且发送了什么广播。如果说能够直接查看到，那是非常好的，这样就不需要google,百度，也不需要深入底层看源码。此篇文章就是告诉你这个调试的小技巧，非常实用哦。

查看android系统广播发送记录

这条命令是

dumpsys |grep BroadcastRecord

敲入这条命令，我的机顶盒打印是

BroadcastRecord2cfa0820 u-1 android.intent.action.TIME_TICK to user -1

从上到下，是按照从新到旧的顺序排列的，也就是说第一行是系统最新发出的一个广播。

dumpsys

这个命令能够打印出系统近期的运行状况，可以找到很多有用的信息。

总结

当你需要系统信息时，可以用dumpsys命令查看系统状态，并在里面找出需要的信息，当只需要查看系统发送过哪些广播时，则用dumpsys |grep BroadcastRecord
