Android ProGuard与org.xmlpull.v1.XmlPullParser错误

当我的应用程序使用ProGuard构建时,它会失败并显示以下消息.
我使用 Android SDK与一些-libraryjars生成的默认proguard.cfg.
我该怎么办？

显然,org.xmlpull.v1.XmlPullParser不是程序类.
我已将ProGuard更新到最新版本(4.6),但具有相同的警告.

解决方法

将此行添加到proguard-project.txt

-dontwarn org.xmlpull.v1.**

并且这行到project.properties

proguard.config=proguard-project.txt
