This file tries to document all requests a client can make
|
|
to the ADB server of an adbd daemon. See the OVERVIEW.TXT document
|
|
to understand what's going on here.
|
|
|
|
HOST SERVICES:
|
|
|
|
host:version
|
|
Ask the ADB server for its internal version number.
|
|
|
|
host:kill
|
|
Ask the ADB server to quit immediately. This is used when the
|
|
ADB client detects that an obsolete server is running after an
|
|
upgrade.
|
|
|
|
host:devices
|
|
host:devices-l
|
|
Ask to return the list of available Android devices and their
|
|
state. devices-l includes the device paths in the state.
|
|
After the OKAY, this is followed by a 4-byte hex len,
|
|
and a string that will be dumped as-is by the client, then
|
|
the connection is closed
|
|
|
|
host:track-devices
|
|
This is a variant of host:devices which doesn't close the
|
|
connection. Instead, a new device list description is sent
|
|
each time a device is added/removed or the state of a given
|
|
device changes (hex4 + content). This allows tools like DDMS
|
|
to track the state of connected devices in real-time without
|
|
polling the server repeatedly.
|
|
|
|
host:emulator:<port>
|
|
This is a special query that is sent to the ADB server when a
|
|
new emulator starts up. <port> is a decimal number corresponding
|
|
to the emulator's ADB control port, i.e. the TCP port that the
|
|
emulator will forward automatically to the adbd daemon running
|
|
in the emulator system.
|
|
|
|
This mechanism allows the ADB server to know when new emulator
|
|
instances start.
|
|
|
|
host:transport:<serial-number>
|
|
Ask to switch the connection to the device/emulator identified by
|
|
<serial-number>. After the OKAY response, every client request will
|
|
be sent directly to the adbd daemon running on the device.
|
|
(Used to implement the -s option)
|
|
|
|
host:transport-usb
|
|
Ask to switch the connection to one device connected through USB
|
|
to the host machine. This will fail if there are more than one such
|
|
devices. (Used to implement the -d convenience option)
|
|
|
|
host:transport-local
|
|
Ask to switch the connection to one emulator connected through TCP.
|
|
This will fail if there is more than one such emulator instance
|
|
running. (Used to implement the -e convenience option)
|
|
|
|
host:transport-any
|
|
Another host:transport variant. Ask to switch the connection to
|
|
either the device or emulator connect to/running on the host.
|
|
Will fail if there is more than one such device/emulator available.
|
|
(Used when neither -s, -d or -e are provided)
|
|
|
|
host-serial:<serial-number>:<request>
|
|
This is a special form of query, where the 'host-serial:<serial-number>:'
|
|
prefix can be used to indicate that the client is asking the ADB server
|
|
for information related to a specific device. <request> can be in one
|
|
of the format described below.
|
|
|
|
host-usb:<request>
|
|
A variant of host-serial used to target the single USB device connected
|
|
to the host. This will fail if there is none or more than one.
|
|
|
|
host-local:<request>
|
|
A variant of host-serial used to target the single emulator instance
|
|
running on the host. This will fail if there is none or more than one.
|
|
|
|
host:<request>
|
|
When asking for information related to a device, 'host:' can also be
|
|
interpreted as 'any single device or emulator connected to/running on
|
|
the host'.
|
|
|
|
<host-prefix>:get-product
|
|
XXX
|
|
|
|
<host-prefix>:get-serialno
|
|
Returns the serial number of the corresponding device/emulator.
|
|
Note that emulator serial numbers are of the form "emulator-5554"
|
|
|
|
<host-prefix>:get-devpath
|
|
Returns the device path of the corresponding device/emulator.
|
|
|
|
<host-prefix>:get-state
|
|
Returns the state of a given device as a string.
|
|
|
|
<host-prefix>:forward:<local>;<remote>
|
|
Asks the ADB server to forward local connections from <local>
|
|
to the <remote> address on a given device.
|
|
|
|
There, <host-prefix> can be one of the
|
|
host-serial/host-usb/host-local/host prefixes as described previously
|
|
and indicates which device/emulator to target.
|
|
|
|
the format of <local> is one of:
|
|
|
|
tcp:<port> -> TCP connection on localhost:<port>
|
|
local:<path> -> Unix local domain socket on <path>
|
|
|
|
the format of <remote> is one of:
|
|
|
|
tcp:<port> -> TCP localhost:<port> on device
|
|
local:<path> -> Unix local domain socket on device
|
|
jdwp:<pid> -> JDWP thread on VM process <pid>
|
|
vsock:<CID>:<port> -> vsock on the given CID and port
|
|
|
|
or even any one of the local services described below.
|
|
|
|
<host-prefix>:forward:norebind:<local>;<remote>
|
|
Same as <host-prefix>:forward:<local>;<remote> except that it will
|
|
fail it there is already a forward connection from <local>.
|
|
|
|
Used to implement 'adb forward --no-rebind <local> <remote>'
|
|
|
|
<host-prefix>:killforward:<local>
|
|
Remove any existing forward local connection from <local>.
|
|
This is used to implement 'adb forward --remove <local>'
|
|
|
|
<host-prefix>:killforward-all
|
|
Remove all forward network connections.
|
|
This is used to implement 'adb forward --remove-all'.
|
|
|
|
<host-prefix>:list-forward
|
|
List all existing forward connections from this server.
|
|
This returns something that looks like the following:
|
|
|
|
<hex4>: The length of the payload, as 4 hexadecimal chars.
|
|
<payload>: A series of lines of the following format:
|
|
|
|
<serial> " " <local> " " <remote> "\n"
|
|
|
|
Where <serial> is a device serial number.
|
|
<local> is the host-specific endpoint (e.g. tcp:9000).
|
|
<remote> is the device-specific endpoint.
|
|
|
|
Used to implement 'adb forward --list'.
|
|
|
|
LOCAL SERVICES:
|
|
|
|
All the queries below assumed that you already switched the transport
|
|
to a real device, or that you have used a query prefix as described
|
|
above.
|
|
|
|
shell:command arg1 arg2 ...
|
|
Run 'command arg1 arg2 ...' in a shell on the device, and return
|
|
its output and error streams. Note that arguments must be separated
|
|
by spaces. If an argument contains a space, it must be quoted with
|
|
double-quotes. Arguments cannot contain double quotes or things
|
|
will go very wrong.
|
|
|
|
Note that this is the non-interactive version of "adb shell"
|
|
|
|
shell:
|
|
Start an interactive shell session on the device. Redirect
|
|
stdin/stdout/stderr as appropriate. Note that the ADB server uses
|
|
this to implement "adb shell", but will also cook the input before
|
|
sending it to the device (see interactive_shell() in commandline.c)
|
|
|
|
remount:
|
|
Ask adbd to remount the device's filesystem in read-write mode,
|
|
instead of read-only. This is usually necessary before performing
|
|
an "adb sync" or "adb push" request.
|
|
|
|
This request may not succeed on certain builds which do not allow
|
|
that.
|
|
|
|
dev:<path>
|
|
Opens a device file and connects the client directly to it for
|
|
read/write purposes. Useful for debugging, but may require special
|
|
privileges and thus may not run on all devices. <path> is a full
|
|
path from the root of the filesystem.
|
|
|
|
tcp:<port>
|
|
Tries to connect to tcp port <port> on localhost.
|
|
|
|
tcp:<port>:<server-name>
|
|
Tries to connect to tcp port <port> on machine <server-name> from
|
|
the device. This can be useful to debug some networking/proxy
|
|
issues that can only be revealed on the device itself.
|
|
|
|
local:<path>
|
|
Tries to connect to a Unix domain socket <path> on the device
|
|
|
|
localreserved:<path>
|
|
localabstract:<path>
|
|
localfilesystem:<path>
|
|
Variants of local:<path> that are used to access other Android
|
|
socket namespaces.
|
|
|
|
framebuffer:
|
|
This service is used to send snapshots of the framebuffer to a client.
|
|
It requires sufficient privileges but works as follow:
|
|
|
|
After the OKAY, the service sends 16-byte binary structure
|
|
containing the following fields (little-endian format):
|
|
|
|
depth: uint32_t: framebuffer depth
|
|
size: uint32_t: framebuffer size in bytes
|
|
width: uint32_t: framebuffer width in pixels
|
|
height: uint32_t: framebuffer height in pixels
|
|
|
|
With the current implementation, depth is always 16, and
|
|
size is always width*height*2
|
|
|
|
Then, each time the client wants a snapshot, it should send
|
|
one byte through the channel, which will trigger the service
|
|
to send it 'size' bytes of framebuffer data.
|
|
|
|
If the adbd daemon doesn't have sufficient privileges to open
|
|
the framebuffer device, the connection is simply closed immediately.
|
|
|
|
jdwp:<pid>
|
|
Connects to the JDWP thread running in the VM of process <pid>.
|
|
|
|
track-jdwp
|
|
This is used to send the list of JDWP pids periodically to the client.
|
|
The format of the returned data is the following:
|
|
|
|
<hex4>: the length of all content as a 4-char hexadecimal string
|
|
<content>: a series of ASCII lines of the following format:
|
|
<pid> "\n"
|
|
|
|
This service is used by DDMS to know which debuggable processes are running
|
|
on the device/emulator.
|
|
|
|
Note that there is no single-shot service to retrieve the list only once.
|
|
|
|
sync:
|
|
This starts the file synchronization service, used to implement "adb push"
|
|
and "adb pull". Since this service is pretty complex, it will be detailed
|
|
in a companion document named SYNC.TXT
|
|
|
|
reverse:<forward-command>
|
|
This implements the 'adb reverse' feature, i.e. the ability to reverse
|
|
socket connections from a device to the host. <forward-command> is one
|
|
of the forwarding commands that are described above, as in:
|
|
|
|
list-forward
|
|
forward:<local>;<remote>
|
|
forward:norebind:<local>;<remote>
|
|
killforward-all
|
|
killforward:<local>
|
|
|
|
Note that in this case, <local> corresponds to the socket on the device
|
|
and <remote> corresponds to the socket on the host.
|
|
|
|
The output of reverse:list-forward is the same as host:list-forward
|
|
except that <serial> will be just 'host'.
