android 代码混淆 例子

-optimizationpasses 5
#混淆时不会产生形形色色的类名
-dontusemixedcaseclassnames
#指定不去忽略非公共的库类
-dontskipnonpubliclibraryclasses
#不预校验
-dontpreverify
-dontshrink
#忽略警告
-ignorewarnings

#优化
-optimizations !code/simplification/arithmetic,!field/*,!class/merging/*

#不进行混淆保持原样
 -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

#不混淆第三方jar包 例如：
-keep class javax.xml.** {*; }
-keep class javax.inject.** {*; }
-keep class com.google.inject.** {*; }
-keep class org.springframework.** {*; }
-keep class org.codehaus.jackson.** {*; }
-keep class org.aopallinace.** {*; }
-keep class org.apache.commons.** {*; }

#在代码中用到了泛型，需要加入此标记，不混淆泛型

-keepattributes Signature

-keepclassmembers class **.R$* {
     public static <fields>;
 }
 
-keepclasseswithmembers class * implements java.io.Serializable{   
 <fields>;   
 <methods>;   
}
-keep public class * implements android.os.Parcelable{
     public protected private *;
