Android用Proguard混淆代碼遇到的問題

第一種問題：

Proguard returned with error code 1. See console

Proguard Error 1 
Output:

緣由：由於工程中用了三方的解析，作混淆時沒有-keep引用，就報這個錯了；

解決方法：

在proguard.cfg中加入：

## kxml2-min-2.3.0.jar
-keep public class org.** {*;}這句話，就會又報一個錯，以下：

緣由：第三方的解析和Android自帶的衝突了，

解決辦法：

去第三方的包中將那兩個類給刪掉了，就哦了；

第三：

還遇到一個小問題，我混淆時少寫了一個關鍵字，如：-keep public class org.** {*;} 寫成了-keep public org.** {*;}  就報了以下錯誤：
