| With the rapid development of Internet, mobile terminal which is as a carrier also grows quickly, which promotes the development of mobile terminal operating system. Android owns the largest market share during the terminal operating systems. Android is launched by Google company on November,2007and is an open operating system which is based on linux kernel and widely used on mobile phone and tablet PC. Its system owns the features of stability and strong compatible.These advantages fit for each manufacturers to create their own characteristics system. Now various applications in smart phones come out, however,80%of the information people need is related to location. But many map services still stay on the level which has single function or complex operation. These disadvantages can’t meet the needs of users.Therefore, it is meaningful to develop a friendly interface, fully function mobile track location information system.This article will introduce you a mobile location system which contains nine function modules.(1)The module of map searching can search maps of each city and you can choose satellite mode or traffic mode.The SDK of new version can show the3D effect.(2)The module of city searching can search interesting things in and out of the city.(3)My location labeled by a blue dot in the map.(4)The information of GPS can show you a detail location which can also show you some detail information about mobile,bank and hotel within the scope of around1000meters.(5)Path query can inquire things of transports about bus, driving or walking.

Firstly, the article researches the android operating system deeply and makes you familiar with the overall framework and design ideas. It also helps you know the development process of android and introduce four components of the application. All the theories above provide a solid foundation for development. Secondly, the article analysises the current situation of mobile map service and then analyse the needs of the system. It adopt baidu map’s API to develop. Meanwhile, it introduces the tools of baibu map’s SDK and locating SDK. Thirdly, the article makes a detail system design and analysises the key technology that may be used. Finally, it realizes the coding.All the system’s tests are running on the telephone of Zhongxing U880. The system runs very well and is stable. There is no doubt that it is a friendly interface and fully function mobile track location information system. |
