防范DNSJava库混淆安卓代码

Question

我有一个安卓应用程序，在项目的/libs/目录中有dnsjava.jar。一切都构建的很好，可以打包成APK (没有proguard)。

然而，当我将proguard引入project.properties (在eclipse中)时，我得到了以下警告：

[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

[2013-03-07 14:16:08 - ]    at proguard.Initializer.execute(Initializer.java:321)

在proguard-project.txt中使用-keep类org.xbill.** { *；}似乎不能解决这个问题。

这是用proguard & DNSJava测试的。希望能有所帮助。从asmack自述文件复制

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