ADB tool usage

Introduction to ADB

In order to debug and operate the Android device through the shell , you need the ADB tool (Android Debug Bridge) as a bridge to connect the Android device and the PC.

Environment configuration

Install the ADB software on the PC. After the installation is complete, set the path of the adb main program to the environment variable to facilitate the direct use of the adb command in cmd ; set the Android device to be connected to be in developer mode.

Common commands

1. Log in to the device

adb shell
adb -s device name shell

2. Get root privileges

Sometimes you need rootpermission to operate the Android system, such as when using the chmod command. Use the adb shellcommand to connect to the Android device and execute the following commands in order to obtain rootpermission.

adb root
adb disable-verity
adb reboot
adb root
adb remount

• It should be noted that the userversion of the Android system cannot obtain rootpermission!

3. View connected devices

adb devices

4. Send files from PC to device

adb push local file path remote file path

5. Pull files from the device to the PC

adb pull remote file path local file path

6. View third-party applications

adb shell pm list packages -3

7. Get the application version number

adb shell pm dump com.android.dialer | findstr “versionName”

• Need to know the package name of the application

8. List system applications

adb shell pm list packages -s

9. View cpu architecture information and GPU information

adb shell cat /proc/cpuinfo
adb shell dumpsys | findstr GLES // Get GPU information

10. Check the operating system of the device

adb shell uname
-r View the version of the
operating system -m View the number of bits of the operating system

11. View memory information

dumpsys meminfo

12. getprop command

ro.product.model------equipment model
ro.product.brand------equipment brand
ro.product.name------equipment name

13. View log

adb shell logcat

14. Check the kernel version

adb shell cat proc/version

15. Settings command in adb shell

View screen standby time:
settings get system screen_off_timeout
View wifi switch status:
settings get global wifi_on
current backlight brightness:
settings get system screen_brightness

16. Grab the kernel log

adb shell dmesg> /data/local/tmp/dmesg.txt
or:
cat proc/kmsg

17. Enter fastboot mode

adb reboot bootloader //You
can use the following methods to burn afterwards:
fastboot flash partition name burn file name

18 Install and uninstall apps

adb install the path of the apk in the computer//install the apk in the computer to the phone

Sometimes there will be a Read-only error, we can use the mandatory installation command to install the apk
adb install -r the path of the apk in the computer
// For some apk only used for testing, you need to use the -t option

View installed applications
adb shell pm list packages

Uninstall application
adb uninstall apk full package name

Whether it is installed or uninstalled, it will eventually display the Success
-t parameter for the test package

First: adb shell pm list packages -s find the package name
to be deleted. Get the address of the package name: adb shell pm path com.xx.xx.
Mount the system read and write permissions: adb remount
delete the package: adb shell rm /system/app/ OldDriver/OldDriver.apk and
finally adb reboot will be OK

19. dumpsys command

adb shell dumpsys package com.examle.xx
// versionName in the output information is the application version number
adb shell dumpsys power
// view the number of WakeLock locks, etc.

20. View Android system version and api

Get the system version: adb shell getprop ro.build.version.release
Get the system api version: adb shell getprop ro.build.version.sdk
You can also view the configuration file: cat system/build.prop

21. View the application name and package name of the currently launched APP

dumpsys window -w | grep "name="
For example, the following result:
mSurface=Surface(name=com.xxx.elauncher/com.xxx.elauncher.activity.MainActivity)/@0xcc80e9b

22. Screenshot

adb shell screencap -p /sdcard/01.png
// Capture the current screen

23. Kill the process

Know the process number: adb shell kill pid
adb shell am force-stop package name

24. adb simulated key event

This command is equivalent to pressing the device's Backkey key
adb shell input keyevent 4
to unlock the screen
adb shell input keyevent 82

25. Start the process

For example, start the calculator
adb shell am start -n com.android.calculator2/com.android.calculator2.Calculator

26. View application version

adb shell dumpsys com.seewo.elauncher | findstr version

27. Send Broadcast

adb shell am broadcast -a com.XXXX

Adb network connection equipment method

• method one
  • To download the "Wireless ADB" tool on the Android device, root permissions are required
• Method Two
  • No root permission required

1. Turn on the developer mode on the phone, and then turn on USB debugging
2. Use USB data cable to connect mobile phone and computer
3. Open the cmd command window on the PC and enter adb devices, you can see the connected devices
4. Enter adb tcpip 8888 (set the port number to 8888)
5. Disconnect the phone and computer
6. Enter adb connect device IP address: 8888, the connection is successful

Use busybox

In order to use Linux commands on the adb shell side, you can install the busyboxtool to the Android system; go to the official website to download the compiled busybox tool, push to the Android side, enter the corresponding directory of the shell and execute the following command

chmod 775 busybox-armv8l
./busybox-armv8l --install

execute binary file in adb

Need to copy the bin file to the ##/data/local/tmp## directory, modify the file permissions: chmod 777
