Barcode scanner (including calling webservice)

NOTE: referencing other Android apps you have developed and sharp pricing significantly increases your chance to win the project Basic description of functions needed by me: - create an Android application for Android 2.1+ - scan a barcode from within app - call webservice A to validate barcode and handle response - configure settings for app - search interface within app that calls webservice B to find results and handle response - implement some design See functional requirements for more detailed info. - source code must be delivered upon completion - demo version must be made available for me to test
