In response to the problems of low resident participation and lagging community event handling in traditional community policing grid management, a smart policing community grid management system based on Android is designed. With the aim of diversifying community management entities and innovating community supervision, a four layer network structure consisting of application layer, display layer, control layer, and data management layer is adopted to divide the system into community resident end and community management personnel end; According to the daily management needs of the community, system function design and development are carried out in the Android Studio design environment. The community residents end provides functional applications such as demand reporting, demand tracking and evaluation, and convenient services. The community management personnel end realizes functions such as message service, demand event management, and work log management. The results show that the system can shift the focus of community security management downwards, improve the participation of residents in community management, and police management personnel can efficiently handle community management emergencies using mobile management terminals.
