Abstract
The network infrastructure of China has been improved in recent years. With the
information technology developing, the coverage of computer network has became
universal. Because of the continuous development of the third-party payment tools, the
network Group Buy is increasingly become an important thing to the online Internet
users in their daily life. The current domestic Group Buy Websites, such as Meituan,
Baidu Nuomi, Dazhongdianpin, and so on has launched their mobile phone Group Buy

more and more intense.
Android is a Linux-based open source operating system, mainly for portable
devices, It is announced by Google in November 5, 2007. Although Apple's iOS,
Microsoft's Windows Phone and BlackBerry are also occupy a certain market, But so
far, Android smartphone market still remains strong dominance, shipments continued to
grow. In the Chinese market, Android system reached nearly 84% share of the market,
So choose the Android platform to develop a mobile Group Buy application is very
meaningful.
The System carried out the development of the program interface on client part,
which realize the interface design between client and server. The whole mobile phone
Group Buy system based on C/S architecture, consists of client and server. Client is
responsible for sending requests to the server, the server accepts the request, processes
the request and returns the results to the client. Client consists of an Android application,
the application is based on Eclipse with the Android SDK development; the server is
based on SSH architecture which implements the separation of business logic and the
specific data. The difficulty in the development are mainly concentrated on the
treatment of business logic and data persistence. Business logic relies on the early
resolved demand analysis, and data persistence is solved by using Hibernate technology.
