ADB Usage¶
Introduction¶
Adb( the full name is the Android Debug Bridge) is the command-line debugging tool for Android, and it can complete a variety of functions, such as tracking the system logs, uploading and downloading the files, installing the applications, etc.
Preparing to connect¶
In Android system, go to “Settings” -> “Development options”, check the “USB Debugging” option.Use a micro USB OTG cable to connnect development board and host.
ADB installation for Windows¶
First, please reference Install RK USB driver to get the driver ready.Then go to http://adbshell.com/download/download-adb-for-windows.html to download adb.zip , uncompress it to C:\adb to ease later use.Open a cmd window, input:
cd C:\adb
adb shell
If everything works out, you can enter the adb shell and run the command on the device.
Adb Installation for Ubuntu¶
Install the adb tool:
sudo apt-get install android-tools-adb
Add the device id:
mkdir -p ~/.android
vi ~/.android/adb_usb.ini
# append following line
0x2207
Add the udev rule:
sudo vi /etc/udev/rules.d/51-android.rules
# append following line:
SUBSYSTEM=="usb", ATTR{idVendor}=="2207", MODE="0666"
Replug the USB cable or run the following command so that the udev rule can take effect:
sudo udevadm control --reload-rules
sudo udevadm trigger
Restart the adb server:
sudo adb kill-server
adb start-server
Common Adb Commands¶
Connection Management¶
List all connected devices and their serial numbers:
adb devices
If there are more than one connection device, the serial numbers will be required to distinguish them:
export ANDROID_SERIAL=<device serial no>
adb shell ls
The adb can be connected through the network:
# Restart adbd in device, which will be listened at TCP port 5555.
adb tcpip 5555
# Now, the USB cable can be disconnected.
# Connect to the device, whose IP is 192.168.1.100 here.
adb connect 192.168.1.100:5555
# Disconnect the device
adb disconnect 192.168.1.100:5555
Debug¶
Get the system logs adb logcat¶
Usage
adb logcat [Options] [Label]
Example:
# Show all the log.
adb logcat
# Show only part of the log matching tags specified.
adb logcat -s WifiStateMachine StateMachine
Run the command adb shell¶
Get the detailed running information adb bugreport¶
adb bugreport is used for bug report, which contains lots of useful information about system.
Example:
adb bugreport
# Save to host, then open it with text editor to view adb
adb bugreport >bugreport.txt
root privilege¶
If the userdebug mode is used for TARGET_BUILD_VARIANT, you need to run the following command so as to get the root privilege first:
adb root
Allow the device end of adb to switch to root privilege mode so that commands such as adb remount that require root privileges will succeed.
Application Management¶
Install the application adb install¶
Usage：
adb install [Options] Application.apk
The options include:
-l forward-lock
-r Reinstall application, keeping previous data
-s Install to SD card, instead of internal storage
Example:
# Install facebook.apk
adb install facebook.apk
# Upgrade twitter.apk
adb install -r twitter.apk
If the installation is successful, the tool will return a success prompt “Success”, and if the installation is unsuccessful, in general, it is generally caused by the following conditions:
INSTALL_FAILED_ALREADY_EXISTS: “-r” parameter is needed to reinstall.
INSTALL_FAILED_SIGNATURE_ERROR: The signatures do not match. It sometimes happens that the released application and the debug one have different signatures. If the signature of APK is confirmed to be valid, use adb uninstall to uninstall old application first, then try again to install.
INSTALL_FAILED_INSUFFICIENT_STORAGE: The storage space is not enough, need to check. Install the SD card or uninstall some unused applications to free some space.
Uninstall the application adb uninstall¶
Usage:
adb uninstall ApplicationPackageName
Example:
adb uninstall com.android.chrome
The application package name can be listed with the following command:
The running result is:
package:/system/app/Bluetooth.apk=com.android.bluetooth
It is the apk file in the front, followed by the corresponding package name.
Command line help information adb help¶
Android Debug Bridge version 1.0.31
-a - directs adb to listen on all interfaces for a connection
-d - directs command to the only connected USB device
returns an error if more than one USB device is present.
-e - directs command to the only running emulator.
returns an error if more than one emulator is running.
-s <specific device> - directs command to the device or emulator with the given
serial number or qualifier. Overrides ANDROID_SERIAL
environment variable.
-p <product name or path> - simple product name like 'sooner', or
a relative/absolute path to a product
out directory like 'out/target/product/sooner'.
If -p is not specified, the ANDROID_PRODUCT_OUT
environment variable is used, which must
be an absolute path.
-H - Name of adb server host (default: localhost)
-P - Port of adb server (default: 5037)
devices [-l] - list all connected devices
('-l' will also list device qualifiers)
connect <host>[:<port>] - connect to a device via TCP/IP
Port 5555 is used by default if no port number is specified.
disconnect [<host>[:<port>]] - disconnect from a TCP/IP device.
Port 5555 is used by default if no port number is specified.
Using this command with no additional arguments
will disconnect from all connected TCP/IP devices.
device commands:
adb push [-p] <local> <remote>
- copy file/dir to device
('-p' to display the transfer progress)
adb pull [-p] [-a] <remote> [<local>]
- copy file/dir from device
('-p' to display the transfer progress)
('-a' means copy timestamp and mode)
adb sync [ <directory> ] - copy host->device only if changed
(-l means list but don't copy)
(see 'adb help all')
adb shell - run remote shell interactively
adb shell <command> - run remote shell command
adb emu <command> - run emulator console command
adb logcat [ <filter-spec> ] - View device log
adb forward --list - list all forward socket connections.
the format is a list of lines with the following format:
<serial> " " <local> " " <remote> "\n"
adb forward <local> <remote> - forward socket connections
forward specs are one of:
tcp:<port>
localabstract:<unix domain socket name>
localreserved:<unix domain socket name>
localfilesystem:<unix domain socket name>
dev:<character device name>
jdwp:<process pid> (remote only)
adb forward --no-rebind <local> <remote>
- same as 'adb forward <local> <remote>' but fails
if <local> is already forwarded
adb forward --remove <local> - remove a specific forward socket connection
adb forward --remove-all - remove all forward socket connections
adb jdwp - list PIDs of processes hosting a JDWP transport
adb install [-l] [-r] [-d] [-s] [--algo <algorithm name> --key <hex-encoded key> --iv <hex-encoded iv>] <file>
- push this package file to the device and install it
('-l' means forward-lock the app)
('-r' means reinstall the app, keeping its data)
('-d' means allow version code downgrade)
('-s' means install on SD card instead of internal storage)
('--algo', '--key', and '--iv' mean the file is encrypted already)
adb uninstall [-k] <package> - remove this app package from the device
('-k' means keep the data and cache directories)
adb bugreport - return all information from the device
that should be included in a bug report.
adb backup [-f <file>] [-apk|-noapk] [-obb|-noobb] [-shared|-noshared] [-all] [-system|-nosystem] [<packages...>]
- write an archive of the device's data to <file>.
If no -f option is supplied then the data is written
to "backup.ab" in the current directory.
(-apk|-noapk enable/disable backup of the .apks themselves
in the archive; the default is noapk.)
(-obb|-noobb enable/disable backup of any installed apk expansion
(aka .obb) files associated with each application; the default
is noobb.)
(-shared|-noshared enable/disable backup of the device's
shared storage / SD card contents; the default is noshared.)
(-all means to back up all installed applications)
(-system|-nosystem toggles whether -all automatically includes
system applications; the default is to include system apps)
(<packages...> is the list of applications to be backed up. If
the -all or -shared flags are passed, then the package
list is optional. Applications explicitly given on the
command line will be included even if -nosystem would
ordinarily cause them to be omitted.)
adb restore <file> - restore device contents from the <file> backup archive
adb help - show this help message
adb version - show version num
scripting:
adb wait-for-device - block until device is online
adb start-server - ensure that there is a server running

<tty> refers to the tty for PPP stream. Eg. dev:/dev/omap_csmi_tty1
[parameters] - Eg. defaultroute debug dump local notty usepeerdns
adb sync notes: adb sync [ <directory> ]
<localdir> can be interpreted in several ways:
- If <directory> is not specified, both /system and /data partitions will be updated.
- If it is "system" or "data", only the corresponding partition
is updated.
environmental variables:
ADB_TRACE - Print debug information. A comma separated list of the following values
1 or all, adb, sockets, packets, rwx, usb, sync, sysdeps, transport, jdwp
ANDROID_SERIAL - The serial number to connect to. -s takes priority over this if given.
ANDROID_LOG_TAGS - When used with the logcat option, only these debug tags are printed.
