Android用Proguard混淆代码遇到的…

http://my.oschina.net/u/936286/blog/175062

第一种问题：

Proguard returned with error code 1. See console
ProguardError 1

Output:

Note: there were 678 duplicate classdefinitions.

You must avoid suchdependencies, since the program classeswill

be processed, while thelibrary classes will remainunchanged.

java.io.IOException: Please correct the above warningsfirst.

atproguard.ProGuard.initialize(ProGuard.java:211)

atproguard.ProGuard.execute(ProGuard.java:86)

at proguard.ProGuard.main(ProGuard.java:492)

原因：因为工程中用了三方的解析，做混淆时没有-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，如下：

原因：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-keeppublic org.** {*;} 就报了如下错误：
