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 [email protected]</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
