Android用Proguard混淆代码遇到的问题

第一种问题：

Proguard returned with error code 1. See console

Proguard Error 1 
Output:

缘由：由于工程中用了三方的解析，作混淆时没有-keep引用，就报这个错了；

解决方法：

在proguard.cfg中加入：

## kxml2-min-2.3.0.jar
-keep public class org.** {*;}这句话，就会又报一个错，以下：

缘由：第三方的解析和Android自带的冲突了，

解决办法：

去第三方的包中将那两个类给删掉了，就哦了；

第三：

还遇到一个小问题，我混淆时少写了一个关键字，如：-keep public class org.** {*;} 写成了-keep public org.** {*;}  就报了以下错误：
