Overview

ADB as a tool for interacting and communicating with PC and Android devices

Android Debug Bridge, Android Debugbridge, it is a CS Architecture command-line tool, the role of the PC through the ADB to operate the phone

The composition of the ADB

Client: All commands are PC-initiated and can be installed, uninstalled, and debugged for Android apps (multiple windows or programs can send commands)

Server: Manages the client's connection to the ADB background process on the Android device (commands from different clients are owned by the server and the Android device communicates with each other via a 5037 port connection)

Daemon: Android Background running process, responsible for receiving commands (ADB server and daemon communication is implemented through the adjacent two ports, even-numbered ports (such as 5554) is responsible for processing command line communication, odd ports (such as 5555) is used to maintain the connection, we can see, ADB server can be connected with more than one device, each connection, will be allocated two adjacent ports out, the first pair is 5554/5555, the second pair is 5556/5557, the corresponding, when we are connected to more than one device adb, need to specify the port number or device name, the server will find the corresponding device, for communication)

ADB environment configuration

Download the SDK-------Configure tools and platform-tools two directories into the system environment variable path-----so that you can verify it directly at the command line using the ADB command.

ADB command ADB basic command format

adb [-e |-d |-s< device serial number >]< sub-command >

Parameters	Description
-E	Run only in emulator adb-e shell
-D	Run only on the real machine adb-d shell
-S	Run on the specified device, the device serial number is obtained through ADB device
Help	List adb Help files
Version	List adb versions

ADB Basic command

File transfer and Installation commands

Sub-command	Parameters	Description
Devices	[-l] More information	List all connected devices in three states Device/offline/device not Fount The device is connected properly, the device is disconnected and the device is not found.
Push	<local> <remote>	Copy your computer's local files to your mobile device
Pull	<remote> <local>	Pull phone device files to local
Install	[-LRTSD] <file>	Install APK -L: Identity app as restricted app -R: Replace installation -T: Run the Install test package -S: Install to SD card -D: Allow downgrade installation
Install-mutiple	[-LRTSD] <file ...>	Batch Installation -P: Partial Application Installation
Uninstall	[-K] <package> Find package name can be via command (ADB shell pm List Packages | find "* * *")	Unloading -K: Keep files under Data and cache

Get Info command

Sub-command	Parameters	Description
Wait-for-device	No	Wait for device to connect
Start-server	No	Open ADB Service
Kill-server	No	Kill the ADB service (you can try when the ADB is not connected)
Get-state	No	Get ADB Service Status Offline | bootloader | Device
Get-serialno	No	Get SN number
Get-devpath	No	Get Device-path
Status-window	No	Continuous printing of device status for specified devices (listening status)-use more when doing development tools

Log and restart related commands

Sub-command	Parameters	Description
Bugreport	No	Print the output of the current Dumpsys,sumpstate,logcat
Logcat	More parameters, Need to study separately	Output Android System log
Shell	More parameters, Need to study separately	Go to the remote shell side
Remount	No	Re-mount the system partition, yes the system partition is re-writable (more for push to the system directory before)
Reboot	[bootloader | recovery]	Restart
Reboot-bootloader	No	Reboot to Bootloader
Root	No	Reboot adbd Get root identity
Usb	No	Restart the ADBD to listen for USB, the equivalent of reseating the USB
Tcpip	<port>	Restart ADBD to listen for the specified TCP port

ADB Backup and Restore command

Sub-command	Parameters	Description
Backup (writes a page of data file to the specified file, if the-F output directory is not specified, the Backup.ab in the current directory is saved)	[-f<file>]	Specify the backup directory
	[-apk |-noapk]	Whether to back up the APK file, default to No
	[-obb |-noobb]	Whether to back up OBB packets, default to No
	[-shared |-noshared]	Whether to back up the SD card share content, default to No
	[-all]	Back up all installed apps
	[-system |-nosystem]	Whether to back up system applications,-all including system applications
	[<packages...>]	Back up the specified list of apps
Restore	No	Restore the backup file to your phone

These two commands enable data backup and data recovery between two phones.

The procedure can be a full backup of the phone, the backup process can be encrypted, so that the recovery will require a password

ADB redirection Port command

Port mapping Model

REDIRECT the port (1314) on the development PC to the device's port (5200) so that all data destined for PC port 1314 will be forwarded to device port 5200.

This mechanism enables remote control of Android device applications.

Such as

The following form of the specific order, the application of the follow-up if used to supplement

Sub-command	Parameters	Description
Forward--list	No	List all socket connections
Forward	<local><remote>	REDIRECT Port
Forward--norebind	<local><remote>	REDIRECT port, fails if local port is already occupied
Forward--remove	<remote>	Remove a locally connected socket
Forward--remove-all	No	To remove all locally connected sockets
Reverse--list	No	List the reverse connection sockets for all connected devices
Reverse	<remote><local>	Reverse Connect sockets
Reverse--norebind	<remote><local>	Reverse connection, failed if port is occupied
Reverse--remove	<remote>	Remove a specific reversal socket connection
Reverse--remove-all	No	Remove all specific reversal socket connections

ADB wireless connection and file synchronization

ADB wireless connection can not use USB to directly debug Android device, so that is the TCP/IP connection to operate the device, in fact, and the principle of Operation simulator is consistent

Sub-command	Parameters	Description
Connect		Connect to the device via TCP/IP and use 5555 as the default port if no port number is specified
Disconnect		Disconnect the TCP/IP device, if no port number is specified, use 5555 as the default port, if you use this command without additional parameters, port all connected TCP/IP devices
Sync	[<directory>]	As long as the file changes, it will be automatically copied from the host to the device, you need to specify the environment variable android_product_out to synchronize the directory

Synchronization of the use of the file is more than a number of so files need to be synchronized, if you delete and push words will be a lot of work, this time using synchronous command

Wireless connectivity and synchronization of specific operations to complement the next improvement

ADB connectivity issues adb list of devices attached

Windows:

Install the driver first, see if the Device Manager driver is installed successfully, cannot install the driver can be solved by a phone assistant

Then turn on USB debugging in the phone developer options and allow the PC to always debug the phone usb

First restart ADB with adb kill-server and adb start-server, or use the command to see which process is taking up 5037 ports and then release

At this time if these are ready to be able to connect properly, our phone serial number should have been written to the. Android hidden directory under Windows Adb_usb.ini file, but still the same ADB list of devices attached, At this time we have to consider the automatic connection to write the ADB device number and our terminal using the ADB for the same path, in the appropriate location to write the correct device number, pro-test effective, remember to add 0x

Ubuntu: And the basic ideas under Windows are consistent, specific methods of operation refer to the following posts:

Adb Devices Offline

Port preemption, you can refer to the above method to solve
