-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.
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.

                                ('-s' means install on SD card instead of internal storage)
                                ('--algo', '--key', and '--iv' mean the file is encrypted already)

 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 restore <file>           - restore device contents from the <file> backup archive

 adb help                     - show this help message

networking:

 <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.
