android自动打包方法(ant+proguard+签名)

2022-10-29 16:13:27

前段时间做了一个android的网游项目，现在优化减少体积和防止别人反编译，需要把编译后.class进行混淆，开始在网上看了一些关于 ProGuard的介绍，基本上都是使用ADT自带的打包方式，那个打包方式太慢了，还要手工输密码，一个字烦。

于是开始寻找ant+proguard+签名的打包方式，遗憾的是资料不是缺手就是断脚。

好吧，看来得食自己了，！@#￥@#！@#！@##￥@#￥！@#@ 转眼一周，我++，终于把东西搞出来

ps：我们项目还有一个特殊需求，要把版本号，推广ID打到包里去，方便做推广什么的。这里可以用replace的方法对string.xml进行修改

好吧，废话不说了，直接上build文件

To replace Proguard with a different obfuscation engine:

Override the following targets in your build.xml, before the call to <setup>

-release-obfuscation-check

Check whether obfuscation should happen, and put the result in a property.

-debug-obfuscation-check

Obfuscation should not happen. Set the same property to false.

-obfuscate

** Make sure unless="do.not.compile" is used in the target definition **

check if the property set in -debug/release-obfuscation-check is set to true.

If true:

Perform obfuscation

Set property out.dex.input.absolute.dir to be the output of the obfuscation

-->

<then>

<!-- Set the android classpath Path object into a single property. It'll be

all the jar files separated by a platform path-separator.
