java - Attempted to fix androids "ill-advised or mistaken usage of a core class" went bad -

after trying fix on own have seen around net cannot still figure out means:

i have no idea telling me or start look. recursively including library somehow? build path under order , export thus:

google apis [android 3.0] android dependencies    annotations.jar android private libraries     ton of jars various functionality need: csv writing, talking           google calendar somehow...etc...etc.  jars found on net, not ripped project found solve problems i.e. how access google calendar device , read/write etc...  problem lies? can provide complete list of jars using here. android-support-v4.jar   

i added 1 external jar myself. forget needs if remove it cannot use somethings weird stuff fragmentactivity , that.

so begin can pick project again...get compiling , running on emulator.

libs folder thus: volume in drive d largeworkdisk volume serial number 206c-d951

dalvik jvm not support entire api of oracle jdk. think javax.* packages aren't available android. example there's no awt or swing or graphics2d of java on android.

from error, looks app using class: http://docs.oracle.com/javase/7/docs/api/javax/xml/namespace/qname.html

this shouldn't happen if set ide use android sdk instead of jdk.
