##################################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/*

# Android开发中一些需要保留的公共部分

#############################################

# 保留我们使用的四大组件，自定义的Application等等这些类不被混淆
