The sales of fresh agricultural products are an important part of our national daily life activities. In recent years, China's agricultural investment has continuously increased, and fresh agricultural products require more scientific, standardized, convenient, and safe management. With the rapid development of Internet technology, the rapid development of Android-based online shopping center systems for fresh agricultural products is a major social application trend. Therefore, it is necessary to study the construction of a multifunctional online shopping mall application system for fresh agricultural products based on the Android framework, and explore the integrated development and practical application of various technology systems based on the Android platform and AJAX. Therefore, according to the characteristics and demand features of fresh agricultural products, this paper designs an Android-based online shopping center system for fresh agricultural products and proposes targeted design ideas and implementation plans. The specific design and steps are as follows: (1) System analysis. Carefully study the order and purchase process of online shopping malls, focus on studying the specific work requirements of agricultural products display, customer orders, payment, and storage management, and conduct careful investigations on the origin and product information of various agricultural products, and analyze data structures and data types. Based on the research, the business requirements, functional requirements, and performance requirements of the system design are explained. (2) System design. Based on the system requirements analysis, relevant technologies are applied to explain the overall design ideas and system structure of the system. According to the system requirements, user roles and privileges, functional modules, and databases are designed. (3) System development. Based on the system design, a suitable working environment is constructed, and various functional modules included in the overall design concept are realized based on Android and other technologies.
