Mobile Web Map Service Design Based On Android

With the mobile phone enters into the lives of ordinary people step by step,it will become the main device to obtain information.Therefore,the application services of mobile phone will have great development space,map service is one of them.At present, the map service mainly uses the stand-alone or website way to realize,these methods are not suitable for outdoor tourism,and other occasions,and give the user a lot of inconvenience.The mobile map service is a good solution to the problem,Android platform provides to the general development a function of very flexible display and control the map,which will make the design and implementation of map service have a better platform.In addition,the Android platform is basically free,so can reduce the cost of software effectively,and ultimately lets each user be able to gain the information freely,alse makes a contribution to the popularization of mobile map service.In this paper,there is a analysis and comparison about the status of the current applied platforms like Symbian,Windows Mobile,Mac OS X,RIM and so on.Further analysis of the Android platform,system architecture and component model,and then to resolve the important API in Android and application of composition,and then analyzes Intent and life cycle's mechanism.On this basis,design and develop a mobile map service based on the Android platform,this system includes the self-localization,the map mode,the route inquiry,the place search,browse Dalian,the mobile localization, the walking trail,the creation of record,the list of record and view weather.The self-localization module's function is to display the latitude,longitude and place where mobile users are in the interface.The walking trail module's function is to picture the place which the mobile user passes through by the form of road map.The place search module's function is to inquire a place,and label it in the map.The browse Dalian module's function is used to describe how to display a particular set of latitude and longitude and show the icon in the location-specific and related operations.The view weather module's function is to display the weather conditions about surrounding areas. The creation of record module's function is to save the place map's latitude and longitude and the correlation information what you thought that are important into the database.The list of record module's function is to view,edit,delete the record,and browse the record in the form of map.The mobile localization module's function is to use other people's mobile phones to receive your phone's GPS location coordinates when your phone is lost or stolen,and thus find your mobile phones.This system user-friendly,easy to operate,has good extendibility and maintainability;the system after the teste,can be stable operation,be able to meet the mobile phone users basic map service needs.
