As a tester, you cannot fail to understand ADB commands and operations

Just from web go to app test , A lot of knowledge needs to be added , Make a note of

1. Concept

In fact, what we said adb It's a general term , There are two tools ——Fastboot and ADB

fastboot Quick start ,usb A way to connect data lines

ADB Debug Android or follow app Tools for , It's Android sdk A tool in , With this tool, you can debug Android simulator or real machine

ps： Cold knowledge

commonly Android Device to connect WinXP There is no need to install the driver

2.adb The function of

Operating equipment shell( Command line )

Manage simulator or device Port mapping

Upload between computer and device / Download the file

Will local apk The software is installed into the simulator or android equipment

ADB It's a client - Server side Program , The client is the computer you use to operate , The server side is android equipment . and ADB The driver is the computer and android Client driver for device communication .

All mobile phone operations can be used adb Realization . That is to say, if you play 6, You are the touch screen is completely broken , The display screen is completely broken , Just give you a motherboard , You can still do what you have to do . Of course, this is not recommended in general scenarios , Efficiency first .

ps: download adb When it comes to tools , Many packages pack these two tools together

3. Usage method

a. Download and install on the computer adb Tools

Android Developer website SDK Platform Tools release notes  |  Android Developers  Download the corresponding adb An Zhuo Bao

After decompressing , Configure environment variables , That is to say adb.exe The directory file path of the layer is configured in the environment variable path in

cmd Input adb, If there is adb Version information , Prove that the computer has been installed adb Tool success

ps:

If not configured adb environment variable , It needs to be done first cd To adb.exe Under that directory , Enter again adb Command can succeed

Or in adb.exe The blank space under the folder , Hold down shift+ Right click , The following options appear “ Open here powershell window ”, Get into powershell After window , First enter cmd The command switches to command prompt mode , Input again adb Command to enter adb Pattern

b. Make sure the phone is turned on usb Debug mode

Mobile phone data cable links to computer ,cmd Input in adb devices View the devices that have been successfully linked

c. Through the driver software , Drive elves / Drive life, etc , Put your android The mobile phone driver is installed   ( It's said on the Internet , But I don't know why , My mobile phone doesn't need this step , It's a little strange. )

a.b After operation , We are skilled in mobile phone adb The command operates

4. Principle of use

adb It's a c/s Architecture program , It's made up of three parts

1. Running on the pc Of adb client( client ), Used to run shell perhaps adb command ,adb” The program tries to locate ADB The server , If you can't find it ADB The server ,“adb” The program automatically starts a ADB The server . Next , When the equipment adbd and pc Terminal adb server Once the connection is established ,adb client You can go to ADB servcer Send service request ;

2. Running on the pc Terminal adb server：

ADB Server Is a background process running on the host . Its function is to detect USB Connection and removal of port aware devices , And the start or stop of the simulator instance ,ADB Server Also need to adb client The request was passed usb perhaps tcp Send to the corresponding adbd On ;

3. Resident processes running on the device side adb demon (adbd)：

Program “adbd” As a background process in Android Running in a device or simulator system . What it does is it connects ADB The server , And provide some services for clients running on the host ;

In summary ：

adb There are three major components ：

client （client）

Run on your own computer , Can pass shell To start a client

The server （server）

Running in the background of the computer , Responsible for managing the client and damon communicate

Daemon （damon）

5. Start using adb command , Common operation commands are as follows ：

Basic command format ：

adb [-d|-e|-s ]

-d	Specifies the current unique pass USB Connected Android The device is the command target

-e	Specify the currently unique running simulator as the command target

-s <serialNumber>

Specify the corresponding serialNumber Equipment No / The simulator is the command target

On multiple devices / When the simulator is connected, it is more commonly used to -s Parameters ,serialNumber Can pass adb devices Command acquisition

Such as :

adb -s cf264b8f shell wm size  Get phone screen size

As a test, you need to master adb command ：

1.adb shell Get into adb  shell Pattern

2.adb pull < Mobile path > < Computer path > Pull the files in the mobile phone to the computer   Mobile phone path can be used ls/cd Find it later 3

1.adb install + Package name        adb install apk ( Overlay installation is using -r Options )

2.adb uninstall + Package name       adb uninstall apk

3.adb connect + equipment IP      network connections Android equipment

4.adb reboot        restart Android equipment

5.adb devices      Get the connected device list and device status

6.adb get-state    Get the status of the device ( The state of the device is 3 The clock ,device: The device is connected properly  , offline: Connection exception , Device not responding  , unknown: No device connected )

7. Look at running in Android On the device adb Background processes ：

perform  adb shell ps | grep adbd , You can find the background process ,windows Please use  findstr  replace grep
 

adb shell command ：

adb shell command  
adb The order is adb Some of the commands that come with this program , and adb shell Is called Android Commands in the system , these Android Special orders are placed in Android The equipment system/bin Under the table of contents

8.1. adb shell  bugreport , Print dumpsys、dumpstate、logcat Output , It is also used to analyze errors

More output , It is recommended to redirect to a file

The other one does not need a data line to link the mobile phone adb The way ：

adopt WiFi Remote debugging , At this point, we don't need to pass USB The cable connects the mobile phone to the computer , But there are the following precautions ：

1、 Make sure your phone and computer are on the same network （ Connected to the same router ）

2、 To pass ahead of time adb tcpip 5555 To determine the communication port number

3、 Re pass adb connect Add your own mobile phone ip Address to connect

If you want to cancel the connection , Use it directly adb disconnect Command is enough

start-up adb server command ：

adb command

Some mobile phones need to be unlocked system Partition （ Like millet ）

Burn partition ：fastboot flash < boot/system /recovery/radio/bootloader/ splash1/> 

Problems encountered ：

1.adb root No entry into force

This really does not need to be supported by the kernel , Kernel independent , That is, native . Mobile phones can Authorization tools .

2, After Baidu , Say you need to download first root Tools , obtain root After permission , It's useful to execute the command again ,

It is recommended to download the brush wizard and click on the computer root
