今天，用android4.0在proguard-project.txt中加入
-libraryjars libs/ksoap2-android-assembly-2.6.0-jar-with-dependencies.jar
这句话后，混淆时报上面的错误。
因为项目中用到axis，所以用到了上面的jar。找了找网上资料，有人说加入-ignorewarnings，但这只是打包了，但其实包是用不了的。
于是根据上面错误，自己把ksoap2-android-assembly-2.6.0-jar-with-dependencies.jar中的
org.xmlpull.v1.XmlPullParser
org.xmlpull.v1.XmlSerializer
两个类去掉，混淆通过且能用。
原因：这两个类与android自带的发生了冲突。 您可能感兴趣的文章:详解Android的反编译和代码混淆Android 实现代码混淆的实例Android studio 混淆+打包+验证是否成功AndroidApk混淆编译时，报告java.io.IOException...错误解决办法Android studio利用gradle打jar包并混淆的方法详解Android Studio多渠道批量打包及代码混淆Android 混淆代码详解及实例android app进行代码混淆实例详解Android实用图文教程之代码混淆、第三方平台加固加密、渠道分发Android应用开发之代码混淆ANDROID应用程序的混淆打包分享proguar在Android混淆中的用法
