Suggest -
Web service example generates amazingly accurate search Suggestions.
Suggest matches a partial word or phrase you enter and comes up with a list of possible completions. Select one of the results to do a search on that item.
The results are amazingly accurate, and are refined based on your location and searches other people are doing right now.
This program is a sample from an upcoming edition of "Hello, Android" by Ed Burnette, published by the Pragmatic Programmers. It demonstrates calling web services, multi-threading, XML Parsing, and the Google Suggest API.
