我有一个在项目的 /libs/ 目录中有 dnsjava.jar 的 android 应用程序。一切都很好，可以打包成APK（没有proguard）。

但是，当我将 proguard 引入 project.properties（在 eclipse 中）时，我收到以下警告：

[2013-03-07 14:16:08 - ] Proguard returned with error code 1. See console
[2013-03-07 14:16:08 - ] Warning: org.xbill.DNS.spi.DNSJavaNameServiceDescriptor: can't find superclass or interface sun.net.spi.nameservice.NameServiceDescriptor

使用 -keep class org.xbill.** { *; proguard-project.txt 中的 } 似乎没有解决这个问题。

这是用 proguard & DNSJava 测试的。希望能帮助到你。复制自 asmack 自述文件

# This dnsjava class uses old Sun API
-dontnote org.xbill.DNS.spi.DNSJavaNameServiceDescriptor
-dontwarn org.xbill.DNS.spi.DNSJavaNameServiceDescriptor

# See http://stackoverflow.com/questions/5701126, happens in dnsjava
