一份有用的Android 混淆规则

#指定压缩级别
-optimizationpasses 5

#不跳过非公共的库的类成员
-dontskipnonpubliclibraryclassmembers
#不跳过非公共的库的类
-dontskipnonpubliclibraryclasses

#混淆时采用的算法
-optimizations !code/simplification/arithmetic,!field/*,!class/merging/*

#把混淆类中的方法名也混淆了
-useuniqueclassmembernames

#优化时允许访问并修改有修饰符的类和类的成员
-allowaccessmodification

#将文件来源重命名为“SourceFile”字符串
-renamesourcefileattribute SourceFile
#保留行号
-keepattributes SourceFile,LineNumberTable

#保持所有实现 Serializable 接口的类成员
-keepclassmembers class * implements java.io.Serializable {
     
     
    static final long serialVersionUID;
    private static final java.io.ObjectStreamField[] serialPersistentFields;
    private void writeObject(java.io.ObjectOutputStream);
    private void readObject(java.io.ObjectInputStream);
    java.lang.Object writeReplace();
    java.lang.Object readResolve();
    private *;
    public *;
    void set*(***);
    *** get*();
}

#保持Parcelable不被混淆
-keep class * implements android.os.Parcelable {
     
     
   public static final android.os.Parcelable$Creator *;
}
#-dontwarn com.google.gson.**

#Fragment不需要在AndroidManifest.xml中注册，需要额外保护下
-keep public class * extends android.support.v4.app.Fragment
-keep public class * extends android.app.Fragment
#包名不混合大小写
-dontusemixedcaseclassnames

#混淆时记录日志
-verbose

#关闭预校验
-dontpreverify

#不优化输入的类文件
-dontoptimize

#保护注解
-keepattributes *Annotation*

#保持所有拥有本地方法的类名及本地方法名
-keepclasseswithmembernames class * {
     
     
    native <methods>;
}

#保持自定义View的get和set相关方法
-keepclassmembers public class * extends android.view.View {
     
     
   void set*(***);
   *** get*();
}

#保持Activity中View及其子类入参的方法
-keepclassmembers class * extends android.app.Activity {
     
     
   public void *(android.view.View);
}

#枚举
-keepclassmembers enum * {
    **[] $VALUES;
    public *;
}

#Parcelable
-keepclassmembers class * implements android.os.Parcelable {
     
     
  public static final android.os.Parcelable$Creator CREATOR;
}

#R文件的静态成员
-keepclassmembers class **.R$* {
     
     
    public static <fields>;
}

-dontwarn android.support.**

#keep相关注解
-keep class android.support.annotation.Keep

-keep @android.support.annotation.Keep class * {*;}

-keepclasseswithmembers class * {
     
     
    @android.support.annotation.Keep <methods>;
}

-keepclasseswithmembers class * {
     
     
    @android.support.annotation.Keep <fields>;
}

-keepclasseswithmembers class * {
     
     
    @android.support.annotation.Keep <init>(...);
}

#retrofit 混淆
-dontnote retrofit2.Platform
-dontnote retrofit2.Platform$IOS$MainThreadExecutor
-dontwarn retrofit2.Platform$Java8
-keepattributes Signature
-keepattributes Exceptions
-dontwarn okio.**
#Picasso 混淆
-dontwarn com.squareup.okhttp.**
