Design And Implementation Of Commodity Information Query System Based On Android And Mobile Internet

Mobile Internet age is a new start. It combines mobile communication and Internet together. Mobile devices can access to the Internet resources and application through the WIFI,3G anytime and anywhere. Smart phones are landmark client tools in mobile Internet times. Google launched the software platform designed for mobile equipment, Android, it is a real sense of open mobile equipment comprehensive platform. Open and so on characteristics about Android can promote technology innovation, and help to reduce development costs, still can make operators ordering conveniently characteristic product. Therefore, Android has a large market potential.This paper, based on the Android mobile operating platform and mobile Internet technology, designs the software to query commodity price information. Through inputting inquiring conditions in mobile phone client-side consumers can get information that is price for the same goods in different market at any time and place. So consumer can easily understand commodity prices, such already save shopping time also can buy the lowest price of goods. So greatly improve the efficiency and quality of shopping. And the system increases identification function about planar bar code, bar code, so can directly use the cell phone taking a picture about commodity logo codes to inquire the prices of goods.This system mainly includes the backstage database server, Web server, wireless network, Android client. The client Android smart phone system through wireless network access Web server, if need data access, then visit the backend database. System uses C/S structure mode and MVC mode in software design. This paper discusses the relevant technology of the software development of commodity prices query based on the Android environment; A detailed description of the construction of the development environment; Analysis of the system design mode, software design patterns and database design; The system software development is introduced in detail, including the construction of the system, technology selection, function module and the final design of the user interface. After testing, the software can well realize the default function demand, proving the feasibility of the overall design scheme.
