我有一个基于Android的应用程序,它使用Rest服务连接到Google App Engine,该应用程序完美运行,直到它在发布之前通过ProGuard进行模糊处理.

运行混淆应用程序时LogCat中报告的错误是：

Unable to convert a [application/json,UTF-8] representation into an object of 
  class com.enterprisemk.android.bcw.bincollection.WasteCollectionAreasContainer

org.codehaus.jackson.map.JsonMappingException: No suitable constructor found 
  for type [simple type,class 
  com.enterprisemk.android.bcw.bincollection.WasteCollectionAreasContainer]: 
  can not instantiate from JSON object (need to add/enable type information?)

我在proguard-project.txt文件中有以下内容：

-keepattributes *Annotation*,EnclosingMethod

-keep public class org.w3c.** {public private protected *;}
-dontwarn org.w3c.**

-keep public class org.joda.time.** {public private protected *;}
-dontwarn org.joda.time.**

-keep public class org.restlet.** { *; }
-dontwarn org.restlet.**

-keep public class org.codehaus.** { *; }
-dontwarn org.codehaus.**

-keepattributes Signature
-keepnames class com.fasterxml.jackson.** { *; }
-dontwarn com.fasterxml.jackson.databind.**

而我的班级错误指的是：

public class WasteCollectionAreasContainer {

 public List
