这是在工程中的proguard-project.txt中发现的
# To enable ProGuard in your project, edit project.properties
# to define the proguard.config property as described in that file.## Add project specific ProGuard rules here.# By default, the flags in this file are appended to flags specified# in ${sdk.dir}/tools/proguard/proguard-android.txt# You can edit the include path and order by changing the ProGuard# include property in project.properties.## For more details, see# http://developer.android.com/guide/developing/tools/proguard.html# Add any project specific keep options here:
# If your project uses WebView with JS, uncomment the following
# and specify the fully qualified class name to the JavaScript interface# class:#-keepclassmembers class fqcn.of.javascript.interface.for.webview { # public *;#} 从脚本中可以看到，混淆中保留了继承自Activity、Service、Application、BroadcastReceiver、ContentProvider等基本组件以及com.android.vending.licensing.ILicensingService，
并保留了所有的Native变量名及类名，所有类中部分以设定了固定参数格式的构造函数，枚举等等。(详细信息请参考<proguard_path>/examples中的例子及注释。)
让proguard.cfg起作用的做法很简单，就是在eclipse自动生成的default.properties文件中加上一句“proguard.config=proguard.cfg”就可以了
完整的default.properties文件应该如下：
# This file is automatically generated by Android Tools. # Do not modify this file -- YOUR CHANGES WILL BE ERASED! # # This file must be checked in Version Control Systems. # # To customize properties used by the Ant build system use, # "build.properties", and override values to adapt the script to your # project structure. # Project target. target=android-15 proguard.config=proguard.cfg
Android代码混淆，如何过滤掉反射的R文件及第三方包？解决方案：在Proguard.cfg方件中添加以下设定： - 过滤R文件的混淆：
-keep class **.R$* { *; }
- 过滤第三方包的混淆：
-keep class packagename.** {*;}（其中packagename为第三方包的包名）
Android导入第三方jar包，proguard混淆脚本(屏蔽警告，不混淆第三方包)最近1个项目中 需要导入移动MM的第三方计费包，混淆时用到了如下脚本，可屏蔽警告，不混淆第三方包指定内容。非常有效proguard.cfg 文件-optimizationpasses 5-dontusemixedcaseclassnames-dontskipnonpubliclibraryclasses-dontpreverify-ignorewarnings //这1句是屏蔽警告，脚本中把这行注释去掉-verbose-optimizations !code/simplification/arithmetic,!field/*,!class/merging/*//这1句是导入第三方的类库，防止混淆时候读取包内容出错，脚本中把这行注释去掉-libraryjars libs/mmbilling.jar-dontwarn //dontwarn去掉警告
