Design Of Mobile Positioning Service System Based On Android

The rapid development of mobile communication technology, modern mobile phone function gradually strong, can take photos video, Internet shopping, micro bo chat, games, office, etc., provide the information we need in our life and work. So the development of mobile application service will have broad development space and market value, and mobile location service based location-based services is one of the high-profile service which is closely linked with our life. According to the research of the domestic and foreign research results, found that the tendency of LBS application is higher, most application use GPS technology, combined with other systems such as GIS geographic information system. But a complete GIS system need to computer hardware and software, a strong geographical spatial database to support and occupy a large memory space,and Data processing complex, cumbersome algorithm, develop the software by the component function limit, pay reproduction business expenses, so it is not suitable for mobile phone use and development. Today, however, most of the relevant application software is aimed at a specific area or professional development, the real public service function of application software is rarely and simple.To solve above problems, this system choose GoogleMaps and Android system as a development tool, development of location-based services system based on mobile location services, both are Google’s product, a combination of high compatibility, easy extension, and the foreign free Google announced the Google Maps service API, reduce the development difficulty and cost, the main support Chinese, including Google mobile services package provided by GPS,WIFI, base station positioning technology, the service is stable, use effect is very ideal.This paper has a deep analysis of Android system structure system, systematically summing Android the core of the system API package, a detailed study of the Android application system structure, file composition, data storage operation and basic module, the key research the Android map development the key technology, designed in the Android system platform development and application program flow chart.Through the mobile phone users in the cell phone Map application of demand analysis,combined with Google company provides Map development tools Google Map and the corresponding API library, and has realized the Map of amplification, narrow and display mode conversion, and has designed four big functions of personal Map application, those are selfposition, address query, navigation path and mobile positioning,and in the Android emulator operation commissioning, realize the corresponding function.
