In my Android application in Eclipse I get the following error.
UNEXPECTED TOP-LEVEL EXCEPTION:
java.lang.IllegalArgumentException: already added: Lorg/xmlpull/v1/XmlPullParser;
Conversion to Dalvik format failed with error 1
I solved the problem.
This is a JAR file conflict.
It seems that I have two JAR files on my buildpath that include the same package and classes.
Deleting this package from one of the JAR files solved the problem.
