adb shell dumpsys 调出当前系统信息

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。
