Android: Basic ADB options

Basic ADB options

 

adb

-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 <serial number> – directs command to the USB device or emulator with
the given serial number. Overrides ANDROID_SERIAL
envivornment 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.
devices – list all connected devices
connect <host>:<port> – connect to a device via TCP/IP
disconnect <host>:<port> – disconnect from a TCP/IP device

device commands:
adb push <local> <remote> – copy file/dir to device
adb pull <remote> <local> – copy file/dir from device
adb sync [ <directory> ] – copy host->device only if changed
(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 <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 jdwp – list PIDs of processes hosting a JDWP transport
adb install [-l] [-r] <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)
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 help – show this help message
adb version – show version num

DATAOPTS:
(no option) – don’t touch the data partition
-w – wipe the data partition
-d – flash the data partition

scripting:
adb wait-for-device – block until device is online
adb start-server – ensure that there is a server running
adb kill-server – kill the server if it is running
adb get-state – prints: offline | bootloader | device
adb get-serialno – prints: <serial-number>
adb status-window – continuously print device status for a specified device
adb remount – remounts the /system partition on the device read-write
adb reboot [bootloader|recovery] – reboots the device, optionally into the bootloader or recovery program
adb root – restarts the adbd daemon with root permissions
adb usb – restarts the adbd daemon listening on USB
adb tcpip <port> – restarts the adbd daemon listening on TCP on the specified port

networking:
adb ppp <tty> [parameters] – Run PPP over USB.
Note: you should not automatically start a PPP connection.
<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.

Android: ADB – Mount a filesystem read-write

Mount a filesystem read-write

Very often when you want to write files to a particular partition on ADP1, you will get a “Permission Denied” if the partition is mounted read-only.
To get around this, you need to mount the partition read-write. Typically this is done with /system partition

$adb shell
$ su
$mount -o rw,remount -t yaffs2 /dev/block /mtdblock3 /system

(Replace /dev/block/mtdblock3 & /system with appropriate device path and mount point, as obtained from cat /proc/mounts)
