Getting the sender name in gmail contextual gadget

问题

I’m developing a gmail contextual gadget to get name and email of sender’s email, but I have problem to get name of sender.I tried different ways:

1.Using Custom Extractor

It seems obsoleted and I can not find where I can upload my manifest.xml with custom extractor at “Google Apps Marketplace SDK”. Any Idea!!??

2. Using pre-canned extractors

I defined google.com:SenderEmailExtractor and select “Mail-Sender Address and Mail-Sender Name” scope.Unforthunatly, I just get sender’s email in google.contentmatch.getContentMatches() but there is nothing related to sender’s name! What am I missing?
