Android混淆规则

-ignorewarnings # 忽略警告
-optimizationpasses 5 # 指定代码的压缩级别
-dontusemixedcaseclassnames # 是否使用大小写混合
-dontpreverify # 混淆时是否做预校验
-verbose # 混淆时是否记录日志
-optimizations !code/simplification/arithmetic,!field/*,!class/merging/* # 混淆时所采用的算法

# 保持子类不被混淆
-keep public class * extends android.app.Activity
-keep public class * extends android.app.Application
-keep public class * extends android.app.Service
-keep public class * extends android.content.BroadcastReceiver
-keep public class * extends android.content.ContentProvider
-keep public class * extends android.app.backup.BackupAgentHelper
-keep public class * extends android.preference.Preference
-keep public class com.android.vending.licensing.ILicensingService
# 保持 native 方法不被混淆
-keepclasseswithmembernames class * {
   native <methods>;
}
# 保持自定义控件类不被混淆
-keepclasseswithmembers class * {
   public <init>(android.content.Context, android.util.AttributeSet);
}
# 保持自定义控件类不被混淆
-keepclasseswithmembers class * {
   public <init>(android.content.Context, android.util.AttributeSet, int);
}
# 保持自定义控件类不被混淆
-keepclassmembers class * extends android.app.Activity {
   public void *(android.view.View);
}
# 保持枚举 enum 类不被混淆
-keepclassmembers enum * {
   public static **[] values();
   public static ** valueOf(java.lang.String);
}
#保持Parcelable不被混淆
-keep class * implements android.os.Parcelable {
   public static final android.os.Parcelable$Creator *;
}
# Explicitly preserve all serialization members. The Serializable interface
# is only a marker interface, so it wouldn't save them.
# 保持序列号类不被混淆
-keep public class * implements java.io.Serializable {*;}
-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();
}
