-dontoptimize

 #预校验
-dontpreverify

 #混淆时是否记录日志
-verbose

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

#保护注解
-keepattributes *Annotation*

# 保持哪些类不被混淆
-keep public class * extends android.app.Fragment
-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

##记录生成的日志数据,gradle build时在本项目根目录输出##
#apk 包内所有 class 的内部结构
-dump proguard/class_files.txt
#未混淆的类和成员
-printseeds proguard/seeds.txt
#列出从 apk 中删除的代码
-printusage proguard/unused.txt
#混淆前后的映射
-printmapping proguard/mapping.txt
########记录生成的日志数据,gradle build时 在本项目根目录输出-end######


#如果引用了v4或者v7包
-dontwarn android.support.**

####混淆保护自己项目的部分代码以及引用的第三方jar包library-end####
