| With China’s market economy developing unceasingly and its people’s life quality being greatly improved, the number of people visiting big restaurants is increasing with each passing day. In order to improve its competitiveness, the catering industry is seeking informationization of the business. Nowadays, a variety of mobile terminal equipments have appeared on market. Google’s smart-phone platform, Android, for its unique style and complete system architecture, has become the first choice among others to develop mobile phone terminal system. In view of the demands of market and the boom of developing Android products, this thesis decides it is of great significance to research and develop for catering industry a wireless food&drink ordering system based on the platform of Android.This thesis analyses and studies the operating system, the system architecture, the development kit and as well as the project directory structure of Android mobile phones. In terms of the project application, the thesis conducts an object-orientated requirement analysis, thus producing a table of data and shaping an overall design plan. To improve the response speed of Android client, the developed system has installed on the client side some of the frequently-used-but-seldom-changed data so that the service of data synchronization of Android’s client and the server becomes possible. This thesis aims, by integrating the technology of Android mobile phones, of WLAN and of WEB, to design and implement a wireless food&drink ordering system based on the platform of Android. As the system uses MVC mode of development, it reduces the coupling between modules, and thus improves its maintainability and reusability. In order to make the system easy to handle, most of the data in Android’s client side are shown in graphic forms. Finally, the system is tested on some real cases. The results produced are fundamentally in consistence with what has been expected. |
