I don't think Vector is thread safe in the way you expect did you read:
*"This class is equivalent to
ArrayList<http://developer.android.com/reference/java/util/ArrayList.html> with
synchronized operations. This has a performance cost, and the
synchronization is not necessarily meaningful to your application:
synchronizing each call to get, for example, is not equivalent to
synchronizing on the list and iterating over it (which is probably what you
intended). If you do need very highly concurrent access, you should also
consider
CopyOnWriteArrayList<http://developer.android.com/reference/java/util/concurrent/CopyOnWriteArrayList.html>
. "

http://developer.android.com/reference/java/util/Vector.html
The implication of the above is that your Vector change be changed from
another thread whilst you are trying to serialize it.
