Abstract
With the rapid development of The Times, mankind has entered the information age. With the rapid development of computer communication and the rapid popularization of mobile Internet, electronic information technology has comprehensively changed all aspects of human life. Informatization and intelligence have become the trend of today's social development. With the continuous progress and improvement of science and technology and social and economic levels, smart phones are developing rapidly, with a higher and higher penetration rate and more and more mobile phone applications, which greatly affect people's life, work and entertainment. Nowadays, people have higher requirements for the speed and convenience of mobile phones and more demands for the application software on smart phones. All walks of life are actively moving towards information technology, catering industry is no exception. Campus self-service ordering apps based o
n campus canteens emerge in an endless flow, bringing great convenience to students and gaining popularity among this young group.
This study USES Eclipse and Android SDK development environment to design an online ordering system based on campus canteen. This system is based on the android platform and consists of the student client and the background server. The student client mainly realizes the functions of registration, login, menu category view, menu ordering, shopping cart and personal center. The server mainly realizes user management, dish management, order management and other functional modules. This design can solve the problem of congestion in the campus canteen during the rush hour after class, meet students' demand for ordering food, and bring convenience.
