Android Combat 16: Getprop and Dumpsys commands

After the Android device is connected to the PC, we can do most of the work with the ADB command. Here are some information about the system with Getprop, Dumpsys.

First, Getprop

The simple principle of this command is to read information from various configuration files in the system. Then these files are easy to find after you enter the device inside the ADB shell:

init.rcdefault.prop/system/build.prop

This information can also be displayed by using the Cat command directly.
More commonly used information is listed below
1. Get IP

$ adb shell getprop dhcp.wlan0.ipaddress192.168.0.107

2. Phone Name

$ adb shell getprop ro.product.deviceUlike2$ adb shell getprop ro.product.modelU705T$ adb shell getprop ro.product.nameoppo17_12035

3.serial number

$ adb shell getprop ro.serialno0000012035ABCXXX

4. Screen density

$ adb shell getprop ro.sf.lcd_density240

Well, just use the ADB shell Getprop to print out all the information. You can use the SetProp command to make the corresponding settings.

Second, Dumpsys

When the Android system starts up with a large number of services, we can use the Dumpsys command to see how each service is running. As an Android developer, we should at least understand the presence of these service:

Currently running services:dmagent nvramagent Surfaceflinger accessibility account activity alarm Appwidget Audi o audioprofile Backup battery batteryinfo bluetooth BLUETOOTH_A2DP bluetooth_profile_manager bluetooth_socket CLI Pboard connectivity Content Country_detector cpuinfo device_policy devicestoragemonitor diskstats DRM.

When we need to know the resolution of the device, we can use the following command:

windowwindow displays)Display: mDisplayId=0init=720320dpi cur=720x1280 app=720x1280 rng=720x670-1280x1230layoutNeeded=false

Or

$ adb shell dumpsys window...Display: init=540x960 base=540x960 cur=540x960 app=540x888 raw=540x960
