前言
项目中有用[adb shell dumpsys]，虽然记住几个常用的，但不常用的就很难记住，最近看到相关文章介绍，因此摘抄于此。
好记性不如烂笔头
正文
查看可以dump的service
使用命令
adb shell service list
就出现如下：

也就是说，上面的服务都可以dumpsys的。
dumpsys举例
cpuinfo
adb shell dumpsys cpuinfo
Window
adb shell dumpsys window
我经常用的是获取当前窗口的window
adb shell dumpsys window | grep mFocusedWindow
media.audio_flinger
adb shell dumpsys media.audio_flinger
等等，具体自己试验吧。
