原本放在一起Android项目与发布的文件相混淆。我突然想到，为什么不写博客，分享。有这篇文章的情况下，。

Android代码混淆及项目公布步骤记录

一、清理代码中的调试信息，如Log、System.out

二、在清单文件里改动版本号为当前版本号，假设须要更新数据库，则须要在配置类或配置文件里改动程序数据库版本号。

三、在清单文件里将项目的debugable设置为false

四、创建签名证书keystore文件

五、在项目中的project.properites文件里加入语句proguard.config=proguard-project.txt来指定混淆规则文件

六、配置proguard-project.txt文件

七、假设项目引用了Library Project。则Eclipse应该会在project.properties文件里自己主动生产android.library.reference.1..n=../LibraryProjectName

八、假设项目中包括svntmp(通常位于项目的bin目录下)。在打包时应及时删除,否则会导致打包失败。

九、项目打包，安装測试(最好是使用现有生成包进行升级測试)

附：演示样例proguard-project.txt文件及对应说明：

# This is a configuration file for ProGuard.

# http://proguard.sourceforge.net/index.html#manual/usage.html

# Optimizations: If you don't want to optimize, use the

# proguard-android.txt configuration file instead of this one, which

# turns off the optimization flags. Adding optimization introduces

# certain risks, since for example not all optimizations performed by

# ProGuard works on all versions of Dalvik. The following flags turn

# off various optimizations known to have issues, but the list may not

# be complete or up to date. (The "arithmetic" optimization can be

# used if you are only targeting Android 2.0 or later.) Make sure you

# test thoroughly if you go this route.

-allowaccessmodification

-dontpreverify

#-dontoptimize

# The remainder of this file is identical to the non-optimized version

# of the Proguard configuration file (except that the other file has

# flags to turn off optimization).

文件说明：

0.以上文件拷贝自笔者如今开发的项目。出于项目保护的目的，已将project包名替换com.wly.xxx，读者能够依据自己的项目加以改动！

1.蓝色内容具有通用性质，能够复制黏贴；

2.橙色内容用于指定程序中用到的jar文件(能够看到引用的Library Project不需包括，由于他们已经在project.properties文件里指定了)。

3.红色内容用于表示保留(不混淆)引用的jar包中的内容。

4.草绿色内容用于表示保留本地的bean文件下的实体类不被混淆。

5.紫色内容用于表示保留本地涉及反射的类不被混淆。

6.绿色内容用于特别处理Web JS当地土著调用进程不应被组件之间的混淆。
