Android中adb shell dumpsys相关命令

很多时候,我们也会时不时的使用adb shell dumpsys相关命令,比如:
查看Activity的相关信息(输入包名则查看具体包名的Activity信息):

adb shell dumpsys activity [包名]

查看battery相关信息(输入包名则查看具体包名的battery信息):

adb shell dumpsys batterystats [包名]

查看Location相关信息:

adb shell dumpsys location

然而其中的意义,或许很多人都不知道,我就是其中之一.

其实, 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.

通过以上两个方法查询到运行的system service后，就可以在dumpsys后面加上service的名字，查看指定的service信息。

// 查看Activity相关信息
adb shell dumpsys activity
// 查看CPU相关信息
adb shell dumpsys cpuinfo
// 查看电池使用信息
adb shell dumpsys battery
//查看Window的相关信息,最后部分可以看到分辨率的信息
adb shell dumpsys window

有些service能够接收额外的参数，我们可以使用-h查看帮助信息。

// 查看package这个service的帮助信息
adb shell dumpsys package -h
// 查看activity这个service的帮助信息
adb shell dumpsys activity -h
