adb的全称为Android Debug Bridge，中文名“调试桥”顾名思义adb命令是调试手机中应用的一种方法，而且作为Android SDK中的工具，其功能非常强大，用这个命令行工具可以直接操作管理调试中的Android模拟器或者真机调试中的设备，
它的主要功能列举如下：
运行设备的shell（多种命令行），进行各种操作；
管理模拟器或移动设备的端口映射；
计算机和设备之间的文件传入/传出；
将本地apk软件安装在模拟器或移动设备中

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> " " 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 reverse --list - list all reverse socket connections from device adb reverse <remote> <local> - reverse socket connections reverse specs are one of: tcp:<port> localabstract:<unix domain socket name> localreserved:<unix domain socket name> localfilesystem:<unix domain socket name> adb reverse --norebind <remote> <local> - same as 'adb reverse <remote> <local>' but fails if <remote> is already reversed. adb reverse --remove <remote> - remove a specific reversed socket connection adb reverse --remove-all - remove all reversed socket connections from device adb jdwp - list PIDs of processes hosting a JDWP transport adb install [-lrtsd] <file> adb install-multiple [-lrtsdp] <file...> - push this package file to the device and install it (-l: forward lock application) (-r: replace existing application) (-t: allow test packages) (-s: install application on sdcard) (-d: allow version code downgrade) (-p: partial application install) 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 adb kill-server - kill the server if it is running adb get-state - prints: offline | bootloader | device adb get-serialno - prints: <serial-number> adb get-devpath - prints: <device-path> adb status-window - continuously print device status for a specified device adb remount - remounts the /system and /vendor (if present) partitions 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. 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, /system, /vendor (if present), and /data partitions will be updated. - If it is "system", "vendor" 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. D:adb>
