Many times, we will also use adb shell dumpsys related commands from time to time, such as:
view the relevant information of the Activity (enter the package name to view the Activity information of the specific package name):
adb shell dumpsys activity [包名]View battery related information (enter the package name to view the battery information of the specific package name):
adb shell dumpsys batterystats [包名]View Location related information:
adb shell dumpsys locationHowever, the meaning of it may not be known to many people, and I am one of them.
In fact, the adb shell dumpsys command is used to print out the current system information (more precisely, the dumpsys command, because adb shell is only to enter the shell kernel of the mobile phone or emulator, so that it can execute the dumpsys command), you can follow the command Add the specified service name (such as activity, location), if not, the information of all services in the device will be printed out by default.
The service name that can be added after adb shell dumpsys can be obtained by adb shell dumpsysor adb shell service listmethod. 1. The output information of
