The Design And Implementation Of Track Recording And Display System Based On Android Platform

According to the trajectory reconstruction system development status and application prospect,combined with GPS positioning,GIS map technology,application of current mainstream technology to design and realize the motion trajectory reconstruction system on the platform of Android system,the main research contents are as follows:First,the paper analyzes the development status of the related location information service system,and then,from the whole,introduces the logical structure and related characteristic advantages of the system platform Android used in the development of the system.The application of Baidu map API key in the development process is completed,and the map development package is configured for the implementation process.The common class libraries of location service in Android system are briefly introduced,and the logical function connection among various types is analyzed.The basic characteristics of the database SQLite used in the system are introduced,and the logical structure of SQLite data storage is analyzed and combed.Second,the paper analyzes the functional requirements of the trajectory reconstruction system,and clarifies the principles that need to be followed in the design and development process.The whole work flow of the system is summarized and analyzed,and the main function logic of each functional module of the system is defined through the use case analysis.The overall structure of the system is designed,and the system architecture and the logical structure of the system network are defined.Third,the whole module is divided into modules.According to the idea of module design,the working process of the main functional modules is perfected,and the functional responsibilities of each module are defined.The overall structure of database and data exchange is given.The information elements contained in the system and the logical relations among the information entities are defined by the way of E-R diagram,and each table item of the system database is established.Fourth,the paper introduces the realization of the main functional modules of the motion trajectory reconstruction system,and expounds the general operation process of the realization of various functions.On the basis of completing the whole realization of the system,according to the partition of the function module,the functions of the system are tested in many times and comprehensively,and the realization of each functional logic of the system is verified.At the same time,the overall performance index of the system is tested,and the system is further improved and perfected according to the main problems exposed in the testing process.The trajectory reconstruction system based on motion trajectory reconstruction as the core,with the data as the foundation,to promote scientific fitness users as the starting point,to the existing sports auxiliary software for reference,based on the introduction of appropriate schedule reminding function and dynamic sharing of social function,enrich the system user experience,effectively complete the trajectory reconstruction,and make full use of the motion data,played a very good auxiliary function of sports.
