概述

​ ADB命令之dumpsys的命令是用来查看系统服务相关信息。

​ adb shell dumpsys命令是用于打印出当前系统信息(更切确的说是dumpsys命令,因为adb shell只是为了进入手机或模拟器的shell内核,使其能够执行dumpsys命令),可以在命令后面加指定的service name(比如activity,location),如果不加则默认打印出设备中所有service的信息.

​ 在adb shell dumpsys后面可添加的service name可通过adb shell dumpsys或adb shell service list方法获取.

​

adb shell dumpsys

​ 输出信息的开始部分就是所有运行的service，如下：
