安卓防止反编译，混淆eclipse 的项目代码步骤

1. Eclipse 打开需要打包的项目根目录project.properties文件：如图



2.然后将这句话加入进去

proguard.config=${sdk.dir}/tools/proguard/proguard-android.txt:proguard-project.txt



3.更改项目所引用的SDK中的一个文件

（D:\Tools\android-sdk-windows\tools\proguard）这个是我的sdk的路径打开如图文件



打开是这样的：



然后在后面加上如下图中的几行文字



改好之后，混淆代码，防止编译的步骤也到此结束，在做这些东西前，注意备份！！*_*

下面是proguard-android文件中的全部内容：

# This is a configuration file for ProGuard. # http://proguard.sourceforge.net/index.html#manual/usage.html -dontusemixedcaseclassnames -dontskipnonpubliclibraryclasses -verbose # Optimization is turned off by default.

做完这些工作就可以签名打包了，然后可以使用ApkDec进行反编译，用jd-gui检验自己做的防止反编译的工作是否成功，是否可以不被查看到源代码！
