android ant最簡單的打包簽名及混淆方法

使用ant打包，如果腳本都是我們自己一步一步來寫的話，是一個比較麻煩的東西。

關於ant，我們詳細看下：

ant支持 ant debug，ant release等命令，我們需要簽名混淆，那麼就需要ant release這個命令。

首先：ant環境搭建，這我就不多說了，很多博客都有介紹，包括一些環境配置

然後：ant環境可以之後，我們需要一個 build.xml文件，這個是ant編譯去找的一個東西

<?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>

這個腳本對應  ant 的build.xml就簡單了不是一點點了，不過注意配置環境變量哦。

其中 <import file="${sdk.dir}/tools/ant/build.xml" /> 則是導入ant自帶的那個 build.xml，正因為導入了這個腳本 

<antcall target="release" />這句話才能正常執行

再然後：我們添加一個ant使用的配置腳本：這個腳本是由 ant的build.xml去調用執行的，我們就不管了

文件名為  ant.properties

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

這個不用說也知道是干嘛用的了哦，打開混淆，導入簽名啦。第一行是打開混淆，第二行往下則是導入簽名，以及簽名密碼

至於簽名，就不說啦，有了簽名

key.store=./xxxxx.keystore 這個是給出簽名的路徑，我是直接將簽名拷貝到了工程目錄下了，你可以自己配置哦.

到這裡架子已經搭建出來了哦，接下來就是根據自己的特殊需要，添加一些處理了

這裡稍微花點控件介紹一下混淆

proguard.cfg這個是混淆腳本，由於一些三方包和android自帶的四大組件等等，我們不能讓他們混淆（三方包一般已經混淆過一次，再混淆則會出問題，而四大組建是因為它們會被android系統調用，混淆了，系統就找不到了），否則會出問題

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

我把我的proguard.cfg腳本貼上來哦
