android 程序 发布加密

阅读更多

大家都知道,现在java程序很容易就让别人反编译,andorid 开发也是如此. 所以android 提供了一个 Android Java混淆(ProGuard).使用起来也是很简单.

=================================
在你的android工程下边有一个文件叫:project.properties. 低版本的sdk可能叫default.properties..
只要将 proguard.config=proguard.cfg 这句加到里面 就ok了,但是一定要是发布签名的app,debug模式下是不混淆的.

最后就是这样:

 # 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.
# Indicates whether an apk should be generated for each density.
# split.density=false
# Project target.
target=android-10
proguard.config=proguard.cfg

用clipse export ,导出发布程序就好了.
