Ant 自动打包配置过程

本文主要是介绍Ant 自动打包配置过程，希望对大家解决编程问题提供一定的参考价值，需要的开发者们随着小编来一起学习吧！

ant 安装网上很多这里就不多说，自己百度，这里只是提示下下，环境变量问题

path里最好直接用绝对路径配置，ANT_HOME 有时会不识别，具体原因未知。

Ant 打包apk步骤如下：

生成build.xml文件

在dos下，进入到我们项目的根目录，执行 android update project -n test1 -p . 命令(注意-n表示项目的名称,-p参数后面有个点表示当前目录)。
执行命令后，会在我们的项目下，生成build.xml和local.properties文件。
build.xml 内容如下

<?xml version="1.0" encoding="UTF-8"?>
<project name="test1" 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 intoVersion Control Systems. --><property file="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.dirThe name of the source directory. Default is 'src'.out.dirThe name of the output directory. Default is 'bin'.For other overridable properties, look at the beginning of the rulesfiles in the SDK, at tools/ant/build.xmlProperties related to the SDK location or the project target shouldbe updated using the 'android' tool with the 'update' action.This file is an integral part of the build system for yourapplication and should be checked into Version Control Systems.--><!-- 我们在项目的根目录自己创建 --><property file="ant.properties" /><!-- 替换start --><target name="buildTime"><replaceregexp byline="false" file="./TestProxy.java" replace="public static int mProxy = 34"/></target><!-- 替换end --><!-- if sdk.dir was not set from one of the property file, thenget it from the ANDROID_HOME env var.This must be done before we load project.properties sincethe proguard config can use sdk.dir --><property environment="env" /><condition property="sdk.dir" value="${env.ANDROID_HOME}"><isset property="env.ANDROID_HOME" /></condition><!-- 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 librarydependencies.

custom_rules.xml文件内容如下：
