the kxml2 package is in the j2objc source tree (1.3.1) enter link description here
but I cannot find the kxml2 supported after compile j2objc. Studied from a forum explanation enter link description here, seems like these classes aren't part of the public JRE or Android API. Therefore j2objc will not support it. Is there anyway to add these package manually?
The kxml2 package implements the javax.xml.parsers and org.xml.pull.v1 factory interfaces. These are the public API your app should use for any XML parsing. You can find examples for how to access and use these factories in j2objc's test classes, as well as from a general internet search.
