This paper analyzes the major subjects faced by college students' information processing and maintenance in the informa- tion era and puts forward Ionic and other front-end technologies to design and implement the self-maintenance of Android APP sys- tem with student information. The system mainly realizes student information inquiry and filling, and simplifies the process of stu- dent information collection and processing during the epidemic. Ionic's cross-platform advantage is utilized to provide a strong refer- ence for the design model of application service in the smart campus constructions of colleges.
