Getting Error

Updated syntax of Element annotation to avoid exception – java.lang.RuntimeException: org.simpleframework.xml.core.PersistenceException: Element ‘title’ is already used with @org.simpleframework.xml.Element(data=false, name=title, required=false, type=void) on method ‘title’ at line 41

Tried parsing but getting Runtime exception. I have tried different solutions on stack overflow but they are not working for my case.

Thanks
