我有一个Android应用程序，在项目的/ libs /目录中有dnsjava.jar。一切都很好，可以打包成APK（没有proguard）。
然而，当我将proguard引入project.properties（在eclipse中）时，我收到以下警告：
[2013-03-07 14:16:08 - ] Proguard returned with error code 1. See console

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

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