android 中apk如何防止反编译？

android 2.3以上：

很简单的一句话"在default.properties文件最后添加proguard.config=proguard.cfg"

android2.3及以下：

复制下面default.properties文件到你的工程目录即可,注意target的版本号：

# 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 use,

# "build.properties", and override values to adapt the script to your

# project structure.



# Project target.

target=android-9

proguard.config=proguard.cfg
