That's an old trick that can introduce big problems. You must ensure
that the delimiter doesn't appear in any of the items, and if that's
not possible, you (1) can't use StringTokenizer to parse the string,
and (2) have to invent some kind of quotation mechanism to protect the
delimiter characters that appear in the data, and parse it "by hand."
The approach I'm using is simple. It takes advantage of the fact that
ArrayList is Serializable:
ArrayList<String> strings = new ArrayList<String>(foo.length);
for (Object elt : foo) {
strings.add(elt.toString());
}
Intent broadcastIntent = new Intent(MY_INTENT);
broadcastIntent.putExtra(MY_EXTRA, strings);
Though still not quite satisfactory, because I don't like having to
turn the Integer elements into Strings.
