I have a weird issue. I receive the following error that causes a force-close:
org.apache.harmony.xml.ExpatParser$ParseException: At line 1, column 0:
I ran into the same problem and could make no sense of it because I was parsing directly from the InputSource. When I modified the code to pull the result into a string before the xml parse, I found out the problem was simply a mispelled web service method name and that the error message reported by that service was the killer.
