android ant 最简单的打包签名，混淆方法

使用ant打包，如果脚本都是我们自己一步一步来写的话，是一个比较麻烦的东西。

关于ant，我们详细看下：

ant支持 ant debug，ant release等命令，我们需要签名混淆，那么就需要ant release这个命令。

首先：ant环境搭建，这我就不多说了，很多博客都有介绍，包括一些环境配置

然后：ant环境可以之后，我们需要一个 build.xml文件，这个是ant编译去找的一个东西

 

<?xml version="1.0" encoding="UTF-8"?>
<project
    name="EPAPP"
    default="helpme" >
    <property file="local.properties" />
    <property file="ant.properties" />
    <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' or to inject it through an env var"
        unless="sdk.dir" />
    <import
        file="custom_rules.xml"
        optional="true" />
    <!-- import file="build_of_sdk.xml" / -->
    <import file="${sdk.dir}/tools/ant/build.xml" />
	
    <target
        name="cleand"
        depends="clean" >
		<delete file="./assets/config.properties"/> 
	</target>

    <target
        name="d"
        depends="cleand" >

        <property
            name="out.final.file"
            value="./dist/develop/ep.apk" />
			
		<mkdir dir="./dist/develop"/>
			
        <antcall target="release" />
    </target>

    <target name="helpme">
        <echo>Android Ant Build For EPAPP. Available targets:</echo>
        <echo>   helpme:    Displays this help.</echo>
        <echo>   d:         Builds for final.</echo>
        <echo>              Final release for production.</echo>
        <echo>Please feel free to ask help from wangle@easipass.com</echo>
        <echo>Sorry for this messed English show. :) </echo>
    </target>
</project>

这个脚本对应  ant 的build.xml就简单了不是一点点了，不过注意配置环境变量哦。

 

其中 <import file="${sdk.dir}/tools/ant/build.xml" /> 则是导入ant自带的那个 build.xml，正因为导入了这个脚本 

<antcall target="release" />这句话才能正常执行

再然后：我们添加一个ant使用的配置脚本：这个脚本是由 ant的build.xml去调用执行的，我们就不管了

文件名为  ant.properties

 

proguard.config=proguard.cfg
key.store=./xxxxx.keystore
key.alias=xxxx
key.store.password=123456
key.alias.password=123456

 

这个不用说也知道是干嘛用的了哦，打开混淆，导入签名啦。第一行是打开混淆，第二行往下则是导入签名，以及签名密码

至于签名，就不说啦，有了签名  

key.store=./xxxxx.keystore 这个是给出签名的路径，我是直接将签名拷贝到了工程目录下了，你可以自己配置哦.

到这里架子已经搭建出来了哦，接下来就是根据自己的特殊需要，添加一些处理了

这里稍微花点控件介绍一下混淆

proguard.cfg这个是混淆脚本，由于一些三方包和android自带的四大组件等等，我们不能让他们混淆（三方包一般已经混淆过一次，再混淆则会出问题，而四大组建是因为它们会被android系统调用，混淆了，系统就找不到了），否则会出问题

关于json的混淆尤其要注意，可参考上一篇博客  http://blog.csdn.net/brightshadow11111/article/details/9469159

我把我的proguard.cfg脚本贴上来哦
