Adb的工作原理

android的adb采用的是server+client的方式，所以adb是支持多个设备同时连接的。通过adb devices命令可以看到所有连接的android设备，而多个设备都连上adb server，如果你想针对某一个设备执行adb命令，可以在adb命令后面加上-s ,例如adb –s 12345678 push c:/a.txt /data/。adb的设计可以参考 http://blog.csdn.net/wbw1985/archive/2010/04/02/5443910.aspx。

常用命令

adb shell

有两个比较好用的命令是adb shell am和adb shell pm,这两个命令在frameworks/base/cmds下面。am命令主要用于管理Activity，例如启动，停止Activity（eclipse在运行Activity就使用了这个命令），发送intent；pm命令则主要用于管理应用package的管理，有点像控制面板的添加和删除程序。

am命令的具体用法如下：

usage: am [start|broadcast|instrument|profile]

am start -D INTENT

am broadcast INTENT

am instrument [-r] [-e ] [-p ]

[-w]

am profile [start |stop]

INTENT is described with:

[-a ] [-d ] [-t ]

[-c [-c ] ...]

[-e|--es ...]

[--ez ...]

[-e|--ei ...]

[-n ] [-f ] []

The start command starts activity. Use -D option to make 'DebugOption' true.

The broadcast command sends broadcast.

The instrument command starts instrumentation.

Use -r option to make 'rawMode' true.

Use -e option to add the pair of ARG_NAME and ARG_VALUE into Bundle.

Use -p option to specify profileFile.

Use -w option to make 'wait' true in order to new an instance of InstrumentationWatcher.

Use COMPONENT to specify the name of the instrumentation component.

The profile command turn on/off profiling in a particular process specified by PROCESS.

Use start option to turn on and stop to turn off.Use PROF_FILE to specify the file path of profile.

Use -a to set action specified by ACTION to be performed.

Use -d to create a Uri(data) which parses the given encoded URI string DATA_URI.

Use -t to specify the type specified by MIME_TYPE. Use -c to add a new category specified by

CATEGORY to the intent.

Use -e or --es to add extended data to the intent.EXTRA_KEY specifies the name of the extra data and

EXTRA_STRING_VALUE specifies the string data value.

Use --ez to add extended data to the intent. EXTRA_KEY specifies the name of the extra data and

EXTRA_BOOLEAN_VALUE specifies the serializable data value.

Use -e or --ei to add extended data to the intent. EXTRA_KEY specifies the name of the extra data and

EXTRA_INT_VALUE specifies the serializable data value.

Use -n to explicitly set the component specified by COMPONENT to handle the intent.

Use -f to set special flags controlling how this intent is handled.FLAGS specifies the desired flags.

Use URI to create an intent from a URI.

pm命令的具体用法如下：

usage: pm [list|path|install|uninstall]

    pm list packages [-f]

    pm list permission-groups

    pm list permissions [-g] [-f] [-d] [-u] [GROUP]

    pm list instrumentation [-f] [TARGET-PACKAGE]

    pm path PACKAGE

    pm install [-l] [-r] PATH

    pm uninstall [-k] PACKAGE

    pm enable PACKAGE_OR_COMPONENT

    pm disable PACKAGE_OR_COMPONENT

The list packages command prints all packages.  Use

the -f option to see their associated file.

The list permission-groups command prints all known

permission groups.

The list permissions command prints all known

permissions, optionally only those in GROUP.  Use

the -g option to organize by group.  Use

the -f option to print all information.  Use

the -s option for a short summary.  Use

the -d option to only list dangerous permissions.  Use

the -u option to list only the permissions users will see.

The list instrumentation command prints all instrumentations,

or only those that target a specified package.  Use the -f option

to see their associated file.

The path command prints the path to the .apk of a package.

The install command installs a package to the system.  Use

the -l option to install the package with FORWARD_LOCK. Use

the -r option to reinstall an exisiting app, keeping its data.

The uninstall command removes a package from the system. Use

the -k option to keep the data and cache directories around

after the package removal.

The enable and disable commands change the enabled state of

a given package or component (written as "package/class").

frameworks/base/cmds下面还有一个别的命令,如下

dumpstate

dumpsys

ime

input

installd

runtime

service

servicemanager

surfaceflinger

svc

system_server

下面是上述命令的一些输出：

ADB高级应用

一、利用无线来查看adb shell

> adb tcpip 5555

连接：

> adb connect IP:5555

见后文《调试注意事项》

二、模拟按键

 > adb shell input keyevent "value"

部分常见按键对应值：

Key  | Constant Value

Back 4

Power 26

Menu 82

Home 3

Search 84

方向键：

上 19

下 20

左 21

右 22

确认（类似单击）：23

三、adb shell下查看系统盘符

 > adb shell df

四、adb shell下挂载系统

> adb shell

> busybox mount -o remount,rw /system

五、adb shell 下移除USB设备

> adb shell

> vdc unshare /mnt/sdcard ums

六、adb shell 下查看内核信息

> cat /proc/kmsg &

七、查看build配置的值（以heap为例）

> adb shell getprop | grep heap

八、通过sendevent 模拟按键以及鼠标

直接用input实现：

> adb shell input keyevent 3

> adb shell input tap 250 250

> adb shell input swipe 250 250 300 300

九、查看屏幕显示的fps

开启系统属性：debug.sf.fps=1
然后直接logcat -s SurfaceFlinger -v time
（看SurfaceFlinger里面打印出来时多少）

十、查看当前运行程序栈

> dumpsys window windows | busybox grep "Window #"

十一、查看当前设备DDR运行频率

> cat /proc/clocks | busybox grep "ddr"

十二：ADB logcat过滤

adb logcat -s TAG_NAME
adb logcat -s TAG_NAME_1 TAG_NAME_2

adb logcat “*:PRIORITY”

adb logcat -s TAG_NAME:PRIORITY
adb logcat -s TAG_NAME_1:PRIORITY_1 TAG_NAME_2:PRIORITY

优先级（PRIORITY）分为以下几种：

V – Verbose
D – Debug
I – Info
W – Warning
E – Error
F – Fatal
S – Silent

范例：

> adb logcat *:E 查看异常信息

> adb logcat -s "TAG"  过滤TAG

十三：查看设备是否拥有su权限(4.2及之前版本)

> adb shell
> ps
# 会列出系统进程
# 选一个u开头的 表示普通程序
> su u0_a8
#切换到u0_a8下 #号变 >
> su
#如果可以执行，>号为#号，则表示有su权限，如果提示权限问题，就没有su权限

十四：查看应用引用

adb 查看Android应用所有引用

> adb shell

> ps  （查看PID号）

> cd /proc/PID号/fd

> busybox ls -l

也将文件拷贝出来

> cat xxx > /sdcard/xxx

十五：获取运行内存/CPU信息

> adb shell

> cat /proc/meminfo

> cat /proc/cpuinfo

十六：抓取Logcat信息及kmsg信息

 # cat proc/kmsg >/data/kmsg.txt & 
 # logcat -v time >/data/logcat.txt &

十七：查看Android（手机\平板\开发板等）设备信息

> adb shell dumpsys package > package.xml

     (此命令可显示手机（平板）可供应用查询到的library和feature)

十八、输出所有已经安装的应用

> adb shell pm list packages -f

十九、查看预安apk

> adb shell pm list packages -3

二十：清除logcat缓冲区

(用这个命令来清除一些重复出现的过时的日志)
> adb logcat -c

二十一、目前认为最牛的adb命令：截取屏幕图片

截图直接保存到电脑

$ adb shell screencap -p | sed 's/\r$//' > screen.png

执行adb shell 将\n转换\r\n, 因此需要用sed删除多余的\r

如果直接当命令用还可以用 alias 包裝装起來

$ alias and-screencap="adb shell screencap -p | sed 's/\r$//'"
$ and-screencap > screen.png

以后就可以方便的用and-screencap > 直接将截图保存到电脑上了

其他入门级但也比较常见的adb命令

1、查看所有已经连接上的设备

adb devices

如果有多个设备连接到电脑，可以通过 adb -s DEVICE_ID 来指定用哪一个

2、挂载system分区(当然需要设备支持)

adb remount

3、安装与卸载应用

adb install
adb install -r     通过install命令来安装apk文件，-r参数可以重新安装某个应用并保留应用数据

#举例
adb install -r ~/chrome.apk

卸载应用：
adb uninstall <软件名>

adb uninstall -k <软件名>        如果加 -k 参数,为卸载软件但是保留配置和缓存文件
#举例
adb uninstall com.android.chrome

4、启动一个Activity

adb shell am start 包名/.类名
adb shell am start 包名/类的全名

5、登录设备shell

adb shell --这个命令将登录设备的shell.
adb shell      后面加将是直接运行设备命令, 相当于执行远程命令

6. 从电脑上发送文件到设备

       --用push命令可以把本机电脑上的文件或者文件夹复制到设备(手机)

adb remount    ## remount '/system'分区 as read-write

adb push <本地路径> <远程路径>

7. 从设备上下载文件到电脑

       --用pull命令可以把设备(手机)上的文件或者文件夹复制到本机电脑

adb pull <远程路径> <本地路径>

8. 显示帮助信息(包括各种命令用法与含义) 

adb help

1.模拟功能按键

命令格式：adb shell sendevent [device] [type] [code] [value]

如： adb shell sendevent /dev/input/event0 1 229 1 代表按下按下menu键

adb shell sendevent /dev/input/event0 1 229 0 代表按下松开menu键

说明：上述的命令需组合使用

另外所知道的命令如下：

Key Name CODE

MENU 229

HOME 102

BACK (back button) 158

CALL (call button) 231

END (end call button) 107

2. 发送鼠标事件(Touch)：

命令格式：adb shell sendevent [device] [type] [code] [value]

情况1：在某坐标点上touch

如在屏幕的x坐标为40，y坐标为210的点上touch一下，命令如下

adb shell sendevent /dev/input/event0 3 0 40

adb shell sendevent /dev/input/event0 3 1 210

adb shell sendevent /dev/input/event0 1 330 1 //touch

adb shell sendevent /dev/input/event0 0 0 0 //it must have

adb shell sendevent /dev/input/event0 1 330 0 //untouch

adb shell sendevent /dev/input/event0 0 0 0 //it must have

注：以上六组命令必须配合使用，缺一不可

情况2:模拟滑动轨迹（可下载并采用aPaint软件进行试验）

如下例是在aPaint软件上画出一条开始于（100,200），止于（108,200）的水平直线

adb shell sendevent /dev/input/event0 3 0 100 //start from point (100,200)

adb shell sendevent /dev/input/event0 3 1 200

adb shell sendevent /dev/input/event0 1 330 1 //touch

adb shell sendevent /dev/input/event0 0 0 0

adb shell sendevent /dev/input/event0 3 0 101 //step to point (101,200)

adb shell sendevent /dev/input/event0 0 0 0

…………………… //must list each step, here just skip

adb shell sendevent /dev/input/event0 3 0 108 //end point(108,200)

adb shell sendevent /dev/input/event0 0 0 0

adb shell sendevent /dev/input/event0 1 330 0 //untouch

adb shell sendevent /dev/input/event0 0 0 0

调试注意事项

当调试那些使用了USB外设和主机特性的应用时，你很有可能把你的USB硬件连接到你的Android设备上，这将阻止你通过USB建立adb到Android设备的连接。你通过网络仍可以访问adb。通过网络连接adb：

1. 通过USB将Android设备连接到电脑。

2. 从SDK 的 platform-tools 目录，在命令行输入adb tcpip 5555

3. 输入：adb connect <设备的IP地址>:5555 ，你现在将被连接到Android设备并能像adb logcat一样发出通用的adb命令。

4. 要设置你的设备监听USB，输入adb usb 。

ADB很强大，记住一些ADB命令有助于提高工作效率。

1. 获取序列号：

   adb get-serialno

2. 查看连接计算机的设备：

   adb devices
