Android simplexml.jar proguard问题

概述我只是尝试通过simple-xml-2.6.jar解析一个简单的xml文档.我把这个jar放到一个名为lib的文件夹中,然后将它添加到库中.然后我尝试跳过这个jar,所以在proguard.cfg中的代码如下所示： -optimizationpasses 5-dontusemixedcaseclassnames-dontskipnonpubliclibraryclasses-dontprev 我只是尝试通过simple-xml-2.6.jar解析一个简单的xml文档.我把这个jar放到一个名为lib的文件夹中,然后将它添加到库中.然后我尝试跳过这个jar,所以在proguard.cfg中的代码如下所示：

我想要涵盖所有异常但它显示的logcat：

解决方法 我也有同样的问题.

我认为这是因为proguard更改了Annotation属性的名称.
例如,注释属性定义为：

public @interface Attribute{    public String name() default "";    public String empty() default "";}

但是在混淆之后,它变成了：

public @interface Attribute{    public abstract String a();    public abstract boolean b();}

然后,在运行时,代码将无法通过反射获取属性名称.
