Android混淆打包

在Android应用程序也可以使用 ProGuard来进行混洗打包，大大的优化Apk包的大小。但是 注意 ProGuard 对文件路径的名名很有讲究，不 支持括号 ，也不 支持空格 。 在混淆过后，可以在工程目录的 proguard中的 mapping.txt 看到混淆后的类名，方法名，变量名和 混淆前的类名，方法名，变量名。
在使用Eclipse或 Ant 打包应用程序时，都是使用Android工程目录的project.properties 文件来指定配置。关于Android中如何使用ant打包请参考《Android中使用Ant编译打包 》
在使用Eclipse新建一个工程，都会在工程目录下生产配置 project.properties和proguard-project.tx 。
# To enable ProGuard toshrink and obfuscate your code, uncomment this (availableproperties: sdk.dir, user.home):
#proguard.config=${sdk.dir}/tools/proguard/proguard-android.txt:proguard-project.txt
# Project target.
target=android-10
project.properties 用于配置Android工程的一些属性，#号的话表示当前行是注释，这里的 proguard.config 就用于指定 ProGuard的 混淆配置文件，并对使用 release方式打包应用程序时开启 代码混淆 功能。对于是否是 使用release方式打包，和AndroidManifest.xml 中application的android:debuggable属性有很多关系。如果该值为 android:debuggable=" true " ，那么最终就是 debug方式打包。最明智的方式就是在 AndroidManifest.xml并不显示的指定它，而是是打包工具在打包时来决定它最终的值。 对于ant就是 ant release 或 ant debug。 而对于直接在Eclipse中使用run 或 debgu 来打包的话就是debug,使用export的话就是 release.
proguard . config = $ { sdk . dir }/ tools / proguard / proguard - android . txt : proguard- project . txt
这里的话指定了混淆的基本配置文件 proguard-android.txt ，和 混淆的个性化配置文件 proguard-project.txt。这里 proguard-project.txt文件用于对前面的 基本的混淆配置文件 proguard-android.txt 的配置进行override和添加。
混淆的基本配置文件 proguard-android.txt 如下：
