Location-Based Services Design and Implementation Using Android Platforms

摘要

Mobile computing research evolves constantly and quickly. New mobile devices, technologies, methods, or applications are introduced every day. One of the mobile applications, location-based service (LBS), has attracted great attention recently. A location-based service is a service based on the geographical position of a mobile handheld device. Two of the LBS examples are finding a nearby ethnic restaurant and comparing prices of a product from different stores. Though location-based services are popular, most developers are not familiar with its design and implementation. This paper studies the LBS structure by dividing an LBS system into five components: (i) mobile handheld devices, (ii) positioning system, (iii) mobile and wireless networks, (iv) service providers, and (vi) geographical data providers. Subjects related to LBS implementation including (i) LBS system structure, (ii) handheld computing, (iii) Android application development, and (iv) embedded database SQLite are detailed in this paper. The final section gives a summary of this article and suggests future directions and possible projects of location-based services.
