添加simple-xml-2.6.jar之后apk打包报错解决办法

前端时间添加simple-xml-2.6.jar之后apk打包失败，报了下面一堆错误，解决办法如下：

在proguard-rules.pro中加入一下三行，问题即可解决：

-dontwarn javax.xml.stream.events.**
-keep class org.simpleframework.xml.**{*;}
-dontwarn org.simpleframework.xml.**

也可以试一下以下两行，有可能会出现xml解析失败的情况

#simple-xml-2.6.jar
-dontwarn javax.xml.stream.events.**
-dontwarn org.simpleframework.xml.stream.**
