代码混淆

代码混淆

下面是常见的的proguard.cfg配置项：

# 指定代码的压缩级别-optimizationpasses 5# 包明不混合大小写-dontusemixedcaseclassnames# 不去忽略非公共的库类-dontskipnonpubliclibraryclasses # 优化不优化输入的类文件-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-keep public class * extends android.app.backup.BackupAgentHelper-keep public class * extends android.preference.Preference-keep public class com.android.vending.licensing.ILicensingService# 如果有引用v4包可以添加下面这行-keep public class * extends android.support.v4.app.Fragment# 忽略警告-ignorewarning#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 class_files.txt# 未混淆的类和成员-printseeds seeds.txt# 列出从 apk 中删除的代码-printusage unused.txt# 混淆前后的映射-printmapping mapping.txt#记录生成的日志数据，gradle build时 在本项目根目录输出-end#####混淆保护自己项目的部分代码以及引用的第三方jar包library#-libraryjars libs/umeng-analytics-v5.2.4.jar#三星应用市场需要添加:sdk-v1.0.0.jar,look-v1.0.1.jar#-libraryjars libs/sdk-v1.0.0.jar#-libraryjars libs/look-v1.0.1.jar#如果不想混淆 keep 掉-keep class com.lippi.recorder.iirfilterdesigner.** {*; }#友盟-keep class com.umeng.**{*;}#项目特殊处理代码#忽略警告-dontwarn com.lippi.recorder.utils**
