 一、adb实现原理

adb的目的是想仅在PC端执行adb操作来获取手机里面的文件或向手机内部发送文件。这是通过Ubuntu中adb操作作为客户端与Ubuntu中运行的adb service交互,Ubuntu中运行的adb service与手机中运行的adbd守护进程交互实现的。

设备端(eg:手机)在启动后会启动一个名为adbd的守护进程,来监听PC通过adb发来的请求。Ubuntu中默认是不会启动启动adb服务的,但是执行adb devices的时候若是adb server还没有启动,就会通过"adb -P 5037 fork-server server"来启动adb服务服务。此后,Ubuntu中运行adb就作为client向Ubuntu中的adb service发起请求,然后Ubuntu中的adb server与手机里面的adbd守护进程通信。

二、adb操作

1.Ubuntu要获取手机中的一个文件:

# adb devices 
* daemon not running. starting it now on port 5037 * 执行的时候adb server还没有运行,然后就启动adb server。 
* daemon started successfully * 
List of devices attached  
FA4412DBA4120433    device    表示一个device已经attach到Ubuntu中了。 
 
# adb pull /data/Hello.class ./

2.Ubuntu要向手机发送一个文件

# sdb push test.txt /data    上面adb server已经启动了,这里就不需要再启动adb server了。

3.adb shell

若Ubuntu中执行了adb shell就相当于这个窗口做了一个串口控制台一样,成为了手机的串口终端了。可以在Ubuntu中另外打开一个窗口来和这个“串口终端”交互。此时Ubuntu和手机的交互就像Ubuntu中的两个窗口之间的交互一样。

三、adb排错

1.首先要确保手机端的adbd守护进程和Ubuntu中的adb server都正常运行起来了。

2.Ubuntu中可以重启adb服务试试:adb kill-server 然后 adb start-server

                                 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. 
 -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)

 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

                                 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.)

                                    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 disable-verity           - disable dm-verity checking on USERDEBUG builds 
  adb keygen <file>            - generate adb public/private key. The private key is stored in <file>, 
                                 and the public key is stored in <file>.pub. Any existing files 
                                 are overwritten. 
  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 
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.

四、adb相关命令

1. adb install

adb install [-lrtsdg] <file> 
    - push this package file to the device and install it

adb install 一共有lrtsdg六个选项
(1) -l 锁定该应用程序
(2) -r 替换已存在的应用程序,也就是说强制安装
(3) -t 允许测试包
(4) -s 把应用程序安装到sd卡上
(5) -d 允许安装的比手机上带的版本低
(6) -g 为应用程序授予所有运行时的权限

五、多个设备adb链接

1. 多个设备使用:adb -s <设备id> <操作命令>

>adb devices 
List of devices attached 
WCYP8LNRAMQOBUUG        device 
UKEIOZQOKJP7IV45        device 
 
adb -s WCYP8LNRAMQOBUUG shell //链接第一个设备 
adb -s UKEIOZQOKJP7IV45 shell //链接第二个设备

如何区分哪是哪个设备呢,可以通过修改背光看出:

# echo XX > /sys/class/leds/lcd-backlight/brightness

六、命令行关机

reboot 重启 
reboot -p 关机
