之前将所有的混淆都配置在一个 proguard-rules.pro 这个Android Studio新建项目时自动生成的文件里面，而随着项目功能迭代越来越多，代码量越来越多，引用的第二方库、第三方库都越来越多，导致proguard-rules.pro 越来越臃肿，而且随着开发人员增多导致proguard-rules.pro 文件里面的配置越来越混乱。

一、拆分proguard-rules.pro混淆文件

因此今天我将proguard-rules.pro混淆文件进行拆分整理，大概拆分为以下4个文件：第三方混淆文件、第二份混淆文件、系统默认混淆文件、module单独混淆文件 。

如上图所示，四个文件分别为 'proguard-system-common.pro', 'proguard-module.pro', 'proguard-second-party.pro', 'proguard-third-party.pro'

二、配置混淆时候 proguardFiles 所引用的混淆文件

原来的混淆文件配置代码如下：

//混淆文件 proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro', 

改为下面的将四个混淆文件都加入到混淆配置文件列表中

 //混淆文件 proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-system-common.pro', 'proguard-module.pro', 'proguard-second-party.pro', 'proguard-third-party.pro' 

如下图所示：

三、四个拆分的混淆文件具体代码

proguard-system-common.pro

proguard-system-common.pro 是Android系统通用的一些混淆配置，配置的内容大致如下：

# 指定代码的压缩级别 -optimizationpasses 5 -ignorewarnings # 抑制警告 -verbose # 混淆时是否记录日志（混淆后生产映射文件 map 类名 -> 转化后类名的映射 -dontpreverify # 不预校验 -dontoptimize #不优化输入的类文件 -dontshrink #该选项 表示 不启用压缩 混淆时是否做预校验（可去掉加快混淆速度） -dontusemixedcaseclassnames # 混淆时不会产生形形色色的类名 是否使用大小写混合 -dontskipnonpubliclibraryclasses #不跳过(混淆) jars中的 非public classes 默认选项 -keepattributes Exceptions # 解决AGPBI警告 -keepattributes Exceptions,InnerClasses,... -keepattributes EnclosingMethod -keepattributes SourceFile,LineNumberTable #运行抛出异常时保留代码行号 #过滤泛型 -keepattributes Signature #过滤注解 -keepattributes *Annotation* -keep class * extends java.lang.annotation.Annotation { *;

proguard-second-party.pro

proguard-second-party.pro 是我们自己开发的一些存在Maven私服的AAR库的混淆配置

# themeLib -keep class com.xxx.theme.**{*;} -dontwarn com.xxx.theme.** -keep class com.xxx.md5.** {*;} -keep class com.xxx.widget.**{*;} -dontwarn com.xxx.widget.** -keep class com.xxx.http.**{*;}

proguard-module.pro

其中 proguard-module.pro 文件是你们自己模块的单独混淆文件，主要配置下你们项目中所引用到的一些网络和数据库的bean，防止json解析的时候出现解析出null的情况

#所有jackson对应实体类不能混淆 -keep class com.netease.cloudmusic.net.bean.** {*;} #数据库实体类 -keep class com.netease.cloudmusic.dao.bean.** {*;}
