Android 调试命令

Java命令行工具

am工具（启动和调试组件）

am工具的含义为Activity Manager。

start an Activity: am start [-D] [-W] 
-D: enable debugging 
-W: wait for launch to complete 
start a Service: am startservice 
send a broadcast Intent: am broadcast

主要参数Intent： 

显式启动Activity：

am start -n {包名}/{包名}.{活动名}

隐式启动Activity：

am start -a {指定的action} -d {URI}

隐式启动服务：

am startService -a {指定的action}

隐式发送广播：

am broadcast -a {指定的action}

启动Calculator应用：

am start -n com.android.calculator2/com.android.calculator2.Calculator 
Starting: Intent { cmp=com.android.calculator2/.Calculator }

am start -n com.android.calculator2/.Calculator 
Starting: Intent { cmp=com.android.calculator2/.Calculator }

启动应用并带有URL参数：

am start -a android.intent.action.VIEW -d 

Starting: Intent { act=android.intent.action.VIEW dat= }

am start -a android.intent.action.CALL -d tel:12345 
Starting: Intent { act=android.intent.action.CALL dat=tel:xxx-xxx-xxxx }

几种VIEW类型（查看）的启动：

am start -a android.intent.action.VIEW -d file:///sdcard/image.jpg -t image/* 
am start -a android.intent.action.VIEW -d file:///sdcard/audio.mp3 -t audio/* 
am start -a android.intent.action.VIEW -d file:///sdcard/video.3gp -t video/*

几种GET_CONTENT类型（获取）的启动：

am start -a android.intent.action.GET_CONTENT -t image/* 
am start -a android.intent.action.GET_CONTENT -t video/* 
am start -a android.intent.action.GET_CONTENT -t audio/*

注意： 
[–activity-brought-to-front]等的参数和 android.content.Intent类的FLAG_XXX内容相对应。 
-f参数可以直接加代表10进制或者16进制的FLAG数字。

pm工具（应用程序包）

PM工具的含义为Package Manager。

pm

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 list features 
pm path PACKAGE 
pm install [-l] [-r] [-t] [-i INSTALLER_PACKAGE_NAME] [-s] [-f] PATH 
pm uninstall [-k] PACKAGE 
pm enable PACKAGE_OR_COMPONENT 
pm disable PACKAGE_OR_COMPONENT 
pm setInstallLocation [0/auto] [1/internal] [2/external]

列出安装包的信息。

pm list packages -f

另一个文件： /data/system/packages.xml

禁止包（或者组件），清除包的数据，可以排除个别包的影响。

pm disable {包名.组件名} 
pm enable {包名.组件名} 
pm clear {包名}

直接安装包

pm install /sdcard/SkeletonApp.apk

pkg: /sdcard/SkeletonApp.apk Success D/installd( 36): DexInv: 
— BEGIN ‘/data/app/com.example.android.skeletonapp-1.apk’ — D/dalvikvm( 763): DexOpt: load 37ms, verify+opt 52ms D/installd( 
36): DexInv: — END ‘/data/app/com.example.android.skeletonapp-1.apk’ 
(success) —

指定路径，进行安装 
pm set-install-location 
pm get-install-location

input工具（模拟按键工具）

input工具用于模拟用户的按键输入和文本输入。

input

usage: input [text|keyevent] 
input text 
input keyevent 
input tap 
input swipe

模拟按键的输入，按键码参考 android.View.KeyEvent。

input keyevent 82 # 菜单事件（MENU） 
input keyevent 4 # 回退事件 （BACK） 
input text “i_love_beijing” # 输入文字

模拟按键输入可以用于简单的程序调试，在Activity中实现onKeyUp()方法即可。 
Android 4.0+才可以使用tap和swipe子命令。

ime工具（输入法管理）

ime工具用于输入法管理。

ime

usage: ime list [-a] [-s] 
ime enable ID 
ime disable ID 
ime set ID

列出输入法：

ime list 

选择输入法 
ime set 

连续命令行脚本

脚本实际上是利用了Android的shell系统运行的，同样可以传入命令行的参数。 通过使用am调用Activity，通过input进行输入事件，可以模拟一个可执行程序的执行过程。 脚本中还可以传递shell中传入的参数。 
编写一个自动化脚本：

<code class="hljs sql has-numbering" style="display: block; padding: 0px; color: inherit; box-sizing: border-box; font-family: 'Source Code Pro', monospace;font-size:undefined; white-space: pre; border-radius: 0px; word-wrap: normal; background: transparent;">echo $*

运行脚本：

<code class="hljs avrasm has-numbering" style="display: block; padding: 0px; color: inherit; box-sizing: border-box; font-family: 'Source Code Pro', monospace;font-size:undefined; white-space: pre; border-radius: 0px; word-wrap: normal; background: transparent;"> chmod <span class="hljs-number" style="color: rgb(0, 102, 102); box-sizing: border-box;">777</span> test<span class="hljs-preprocessor" style="color: rgb(68, 68, 68); box-sizing: border-box;">.sh</span>
./test<span class="hljs-preprocessor" style="color: rgb(68, 68, 68); box-sizing: border-box;">.sh</span></code><ul class="pre-numbering" style="box-sizing: border-box; position: absolute; width: 50px; top: 0px; left: 0px; margin: 0px; padding: 6px 0px 40px; border-right-width: 1px; border-right-style: solid; border-right-color: rgb(221, 221, 221); list-style: none; text-align: right; background-color: rgb(238, 238, 238);"><li style="box-sizing: border-box; padding: 0px 5px;">1</li><li style="box-sizing: border-box; padding: 0px 5px;">2</li></ul>

（我就不告诉你，很多同学通过这种方式去抓别人app的数据）

命令行和插入式组件结合的调试

Android应用程序APK调试的几个要点：

  • 核心方法是利用命令行的Intent。
  • 单次调用可使用BroadcastReceiver组件
  • 后台调用可使用Service组件
  • BroadcastReceiver组件也可放入其他组件内部
  • 调用的参数使用Intent传入；

启动：am startservice和am broadcast 
首要参数使用-a，数据参数为-d 
AndroidManifest.xml当中要定义IntentFilter 
带数据的Intet和不带数据的Intent命令行不同 
:// : //…/ # ? 
Host是字符串，Port是整数，Path是多个字符串， Segments是字符串，QueryParameter是无顺序的多个参数。 
android.Uri类可以完成参数的

方法：

am startservice -a android.intent.action.testtools.stub1 command://?key=10 
am startservice -a android.intent.action.testtools.stub1 -d command://?key=5 
am startservice -a android.intent.action.testtools.stub2 -d “command://?key1=hello&key2=120” 
am broadcast -a android.intent.action.testtools.stub 
am broadcast -a android.intent.action.testtools.stub command://abc:1234#hello 
am broadcast -a android.intent.action.testtools.stub command:#/sdcard/test.txt 
am broadcast -a android.intent.action.testtools.stub command://abc/hi1/hi2/hi3#hello

注意：不同的Android版本组件是否可以直接使用的问题。

Android的特殊命令

网络配置netcfg

netcfg -h

usage: netcfg [ {dhcp|up|down}]

netcfg

ndc和vdc

vdc volume list 

ndc interface list 

service

service -h

Usage: service [-h|-?] 
service list 
service check SERVICE 
service call SERVICE CODE [i32 INT | s16 STR] … Options: i32: Write the integer INT into the send parcel. s16: Write the 
UTF-16 string STR into the send parcel.

service list 

iphonesubinfo等就是ServiceManager管理的服务名称。 
直接利用Binder方式调用。

属性服务

Android具有prop属性系统，使用getprop和setprop可以获得属性和设置属性。

getprop查看属性值 

getprop ro.secure 

setprop 设置属性值

usage: setprop

watchprops检测属性值变化 
watchprops用于监测属性的变化，直接运行这个命令，将形成循环，将把系统每一个属性的变化列出。

watchprops

<时间> 属性 = ‘属性值’ …… 
<时间> 属性 = ‘属性值’

start和stop命令，用于开始和停止init进程中的service。

start {service_name} 
stop {service_name}

解决Android系统的daemon被kill之后重新启动的问题

系统信息查看小工具

Android中还提供了dumpstate、dumpsys、bugreport等几个工具，用于查看系统各个方面的信息。

  1. dumpstate 
    工具用于将系统设备的状态导出，通过访问sys文件系统和调用其他工具来完成。

  2. dumpsys 
    用于查看应用的状态。 
    由于dumpstate和dumpsys两个工具导出的内容都较多，最好在主机端配合adb来使用。

  3. procrank抓取内存信息 
    procrank工具用于抓取Android进程的内存使用信息。

procrank 

VSS = Virtual Set Size 
RSS = Resident Set Size 
PSS = Proportional Set Size 
USS = Unique Set Size

Android中的Linux命令

由于Android系统基于Linux实现，在系统中可以使用Linux中标准的方法进行调试。在Android中常用的通用Linux的调试方法主要包括以下几个：

  • 系统信息工具（ps、kill、proc文件系统）
  • /dev/设备文件和/sys/文件系统
  • 系统性能工具（vmstat和top）
  • gdb调试

ps和proc查看进程

vmstat在运行过程中，会定期打出一行的内容，表示系统当前的运行

  • r：在运行队列中等待的进程数；
  • b：在等待io的进程数；
  • w：可以进入运行队列但被替换的进程；
  • free：空闲的内存（单位k）；
  • mapped：影射的内存（单位k）；
  • in：每秒的中断数，包括时钟中断；
  • cs：每秒的环境（上下文）切换次数；
  • us：CPU使用时间；
  • sy：CPU系统使用时间；
  • id：闲置时间。
  • VSS（Virtual Set Size）：进程使用的虚拟内存
  • RSS（Resident Set Size）：进程使用的物理内存mstat
