...一般都是用java 吧。。

如果你安装了android SDK，在platform-tools中就能看到adb.exe文件。使用cmd执行adb就能看到adb显示其能用的所有指令了。就像imfunny所说的，devices命令就手机的系列号。

Android Debug Bridge version 1.0.29

 -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                                  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.  devices                       - list all connected devices  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 <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                                  (-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 <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] [-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)                                  ('-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] [-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.)                                  (-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 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   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 reboot-bootloader        - reboots the device into the bootloader   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.

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.

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.
