一份有用的Android 混淆規則

#指定壓縮級別
-optimizationpasses 5

#不跳過非公共的庫的類成員
-dontskipnonpubliclibraryclassmembers
#不跳過非公共的庫的類
-dontskipnonpubliclibraryclasses

#混淆時採用的算法
-optimizations !code/simplification/arithmetic,!field/*,!class/merging/*

#把混淆類中的方法名也混淆了
-useuniqueclassmembernames

#優化時允許訪問並修改有修飾符的類和類的成員
-allowaccessmodification

#將文件來源重命名爲“SourceFile”字符串
-renamesourcefileattribute SourceFile
#保留行號
-keepattributes SourceFile,LineNumberTable

#保持所有實現 Serializable 接口的類成員
-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中註冊，需要額外保護下
-keep public class * extends android.support.v4.app.Fragment
-keep public class * extends android.app.Fragment
#包名不混合大小寫
-dontusemixedcaseclassnames

#混淆時記錄日誌
-verbose

#關閉預校驗
-dontpreverify

#不優化輸入的類文件
-dontoptimize

#保護註解
-keepattributes *Annotation*

#保持所有擁有本地方法的類名及本地方法名
-keepclasseswithmembernames class * {
    native <methods>;
}

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

#保持Activity中View及其子類入參的方法
-keepclassmembers class * extends android.app.Activity {
   public void *(android.view.View);
}

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

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

#R文件的靜態成員
-keepclassmembers class **.R$* {
    public static <fields>;
}

-dontwarn android.support.**

#keep相關注解
-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.**

#alipay
-keep class com.alipay.android.app.IAlixPay{*;}
