Design And Implementation Of Android Client In The Small And Medium-sized Cities Taxi System

When the taxi software has not developed,the problem of taxi in the first and second tier cities is that the passengers can not always get to the taxi quickly even when the number of taxis is enough,so the transportation efficiency is not high.In recent years,the domestic taxi application has developed r Apidly.As an exploration of o2 o mode,the number of users of “fast taxi” and “didi taxi” has risen r Apidly since they were put online,which effectively solved the taxi problem in the first and second tier cities.As a Small and medium-sized city,first of all,the number of passengers and drivers is small,and there is a problem that the habitual place name does not correspond to the name of the place marked by the map,so there are very few users of taxi software that has been widely used in big cities.In view of this situation,the local taxi company decided to develop and promote a local taxi software to solve the problem of user travel and driver work efficiency.This paper mainly studies the application of route query,location display,address query and navigation based on Android platform and Gaud map.Through the research of the above technology,the client of the taxi system is designed and implemented,which realizes the core functions of passenger call request and driver receiving order,checking the empty cars nearby,and taxi process management.The system architecture adopts C / S mode,and the client is divided into passenger end and driver end.Socket and HTTP technology are used to realize data interaction between heterogeneous platforms.The development language is Java.My SQL is used for basic data storage of the server,and redis is used for order data storage with frequent interaction.For the client,sqllite is a lightweight database.In order to verify the feasibility and running efficiency of the system function,the test program,Android mobile phone simulator and multi model real machine are used for running test.Finally,it is determined that the expected functions and requirements of the system are completed and put into use.
