代码混淆 proguard怎么写

Question

如题所述

Answer 1

具体混淆的步骤简单。
首先，我们需要在工程描述文件project.properties中，添加一句话，启用ProGuard。
如下所示：
[java] view plain copy
# This file is automatically generated by Android Tools.
# Do not modify this file -- YOUR CHANGES WILL BE ERASED!
#
# This file must be checked in Version Control Systems.
#
# To customize properties used by the Ant build system edit
# "ant.properties", and override values to adapt the script to your
# project structure.
#
# To enable ProGuard to shrink and obfuscate your code, uncomment this (available properties: sdk.dir, user.home):
proguard.config=${sdk.dir}/tools/proguard/proguard-android.txt:proguard-project.txt

# Project target.
target=android-19

这样，Proguard就可以使用了。当我们正常通过Android Tools导出Application Package时（或者使用ant执行release打包），Proguard就会自动启用，优化混淆你的代码。
导出成功后，你可以反编译看看混淆的效果。一些类名、方法名和变量名等，都变成了一些无意义的字母或者数字，证明混淆成功
