adb简介

adb译为Android设备的桥梁，可以用于快速更新设备中代码，应用或者Android系统升级，在设备上运行shell命令，管理设备或手机模拟器上的端口。

adb原理

Android设备adb授权的原理

在我们的PC机（以windows为例）上启动了adb.exe进程时，adb会在本地生成一对密钥adbkey(私钥)与adbkey.pub(公钥);

根据弹框提示“The computer’s RSA key fingerprint is:xxxx”，可以看出是一对RSA算 法的密钥，其中公钥是用来发送给手机的；

当执行“adb shell”时，adb.exe会将当前PC的公钥(或者公钥的hash值)(fingerprint)发送给android设备；这时，如果android上已经保存了这台PC的公钥，则匹配出对应的公钥进行认证，建立adb连接；如果android上没有保存这台PC的公钥，则会弹出提示框，让你确认是否允许这台机器进行adb连接，当你点击了允许授权之后，android就会保存了这台PC的adbkey.pub(公钥)；



adb分为三个部分：PC上的adb client，adb server和手机（也可能是PC上的模拟器）上的adb daemon。

这是一个多连接的设计。即一台PC可以连接多个手机，一台手机也可以连接多个PC。

ADB Client：

ADB Client：注意这里的Client和Daemon不是一一对应的，Client比如Eclipse DDMS，Windows终端命令行，豌豆荚等。Client本质上就是Shell，用来发送命令给Server。发送命令时，首先检测PC上有没有启动Server，如果没有Server，则自动启动一个Server，然后将命令发送到Server，并不关心命令发送过去以后会怎样。

ADB Server：

ADB Server：运行在PC上的后台程序，目的是检测USB接口何时连接或者移除设备。ADB

Server维护着一个“已连接的设备的链表”，并且为每一个设备标记了一个状态：offline，bootloader，recovery或者online；Server一直在做一些循环和等待，以协调client和Server还有daemon之间的通信。offline说明Server发现了一个设备，但是不能成功连接到Daemon—-这样最好重启一下手机。

ADB Daemon：

ADB Daemon：运行在手机上的一个进程，作用是连接到adb server（通过usb或tcp-ip），并且为client提供一些服务



Adb的运行机制和架构



运行的流程可见之下：

1：PC端adb server发送cmd到小机端

2：adbd(adb daemon)的output thread从/dev/android_usb读取到cmd并解析

（adbd和内核usb driver通过/dev/android_usb进行数据交互）

3：output_thread将解析的cmd写到socketpair的A端

4：fdevent_loop通过select socketpair的B端，得知A端有数据写入，B端可读，然后读取cmd，进行处理（handle_packet）

5：处理完后将结果写到socketpair的B端

6：Input_thread阻塞式读取socketpair的A端

7：Input_thread读取到数据后，写入/dev/android_usb

8：由usb driver将response发给pc端

output_thread负责读取/dev/android_usb，Input_thread负责写入

adb客户端、服务端、守护进程之间的沟通：

1、client调用某个adb命令。

2、adb进程fork出一个子进程作为server。

3、server查找当前连接的emulator/device。

4、server接收到来自client请求。

5、server处理请求，将本地处理不了的请求发给emulator/device。

6、位于emulator/device的adbd拿到请求后交给对应的java虚拟机进程。

7、adbd将结果发回给server。

8、server讲结果发回给client。

C:\Users\admin>adb help
Android Debug Bridge version 1.0.32

-a                            - directs adb to listen on all interfaces for a connection
-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.
-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)

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 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.)

<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.
