通过Android命令自动编译出build.xml文件
原文链接：http://www.xmumu.com/post/2011-11-22/7022215
用途: 做自动集成编译环境.
环境搭配我就不说了(SDK/环境变量等).
进入cmd界面.
进入项目目录.
输入: android.bat list target 来查询我们现有的版本list有哪些.
记住这个ID号码,下的代码面会用到.
输入: android update project -n ButtonDemo -t 1 -p E:\workspace\android\ButtonDemo
-n 对应的是项目名称
-t 就是我们之前查询的SDK版本对应的ID,大家根据自己的项目版本做出选择即可,我这个是android-8 所以用ID 1 .
-p就是生成的路径
成功后显示:
好了以下是生成的build.xml代码段:
<?xml version="1.0" encoding="UTF-8"?>
<project name="ButtonDemo" default="help">
<!-- The local.properties file is created and updated by the 'android' tool.
It contains the path to the SDK. It should *NOT* be checked into
Version Control Systems. -->
<loadproperties srcFile="local.properties" />
<!-- The ant.properties file can be created by you. It is only edited by the
'android' tool to add properties to it.
This is the place to change some Ant specific build properties.
Here are some properties you may want to change/update:
source.dir
The name of the source directory. Default is 'src'.
out.dir
The name of the output directory. Default is 'bin'.
For other overridable properties, look at the beginning of the rules
files in the SDK, at tools/ant/build.xml
Properties related to the SDK location or the project target should
be updated using the 'android' tool with the 'update' action.
This file is an integral part of the build system for your
application and should be checked into Version Control Systems.
-->
<property file="ant.properties" />
<!-- The project.properties file is created and updated by the 'android'
tool, as well as ADT.
This contains project specific properties such as project target, and library
dependencies. Lower level build properties are stored in ant.properties
(or in .classpath for Eclipse projects).
This file is an integral part of the build system for your
application and should be checked into Version Control Systems. -->
<loadproperties srcFile="project.properties" />
<!-- quick check on sdk.dir -->
<fail
message="sdk.dir is missing. Make sure to generate local.properties using 'android update project'"
unless="sdk.dir"
/>
<!-- extension targets. Uncomment the ones where you want to do custom work
in between standard targets -->
<!--
<target name="-pre-build">
</target>
<target name="-pre-compile">
</target>
/* This is typically used for code obfuscation.
Compiled code location: ${out.classes.absolute.dir}
If this is not done in place, override ${out.dex.input.absolute.dir} */
<target name="-post-compile">
</target>
-->
<!-- Import the actual build file.
To customize existing targets, there are two options:
- Customize only one target:
- copy/paste the target into this file, *before* the
<import> task.
- customize it to your needs.
- Customize the whole content of build.xml
- copy/paste the content of the rules files (minus the top node)
into this file, replacing the <import> task.
- customize to your needs.

****** IMPORTANT ******
***********************
In all cases you must update the value of version-tag below to read 'custom' instead of an integer,
in order to avoid having your file be overridden by tools such as "android update project"
-->
<!-- version-tag: 1 -->
<import file="${sdk.dir}/tools/ant/build.xml" />
</project>
