详解Android代码混淆实战

##################################通过混淆配置################################## 代码混淆压缩比，在0~7之间，默认为5，一般不做修改-optimizationpasses 5# 混合时不使用大小写混合，混合后的类名为小写-dontusemixedcaseclassnames# 指定不去忽略非公共库的类-dontskipnonpubliclibraryclasses# 这句话能够使我们的项目混淆后产生映射文件# 包含有类名->混淆后类名的映射关系-verbose# 指定不去忽略非公共库的类成员-dontskipnonpubliclibraryclassmembers# 不做预校验，preverify是proguard的四个步骤之一，Android不需要preverify，去掉这一步能够加快混淆速度。-dontpreverify-dontoptimize# 混淆时是否记录日志-verbose-ignorewarnings# 保留Annotation不混淆-keepattributes *Annotation*# 避免混淆泛型-keepattributes Signature-keepattributes Exceptions,InnerClasses-dontnote com.google.vending.licensing.ILicensingService-dontnote com.android.vending.licensing.ILicensingService# 抛出异常时保留代码行号-keepattributes SourceFile,LineNumberTable-keepattributes Deprecated,Synthetic,EnclosingMethod# 重命名抛出异常时的文件名称-renamesourcefileattribute SourceFile# 指定混淆是采用的算法，后面的参数是一个过滤器# 这个过滤器是谷歌推荐的算法，一般不做更改-optimizations !code/simplification/cast,!field/*,!class/merging/*
