【正文】 ith many work devices, and support advanced rich multimedia applications. Moreover, all of which must be implemented in a resourcelimited embedded system under restricted conditions. Android technology provides crossplatform capability, and supports a variety of devices devices. Android technology for wireless devices to create a new development platform that lets mobile munications equipment to play the greatest potential. Android phone as a mobile terminal provides a good solution for the future development of mobile munication. In this paper, the Android system characteristics, system architecture and application build, developers have done a more detailed analysis. Combination Baidu Maps, GPS positioning technology, positioning and navigation android conducted indepth research and design of bus routes Androidbased query application. The system uses the Java language and Eclipse development tools to write. At the same time gives a detailed system design process, part of the interface diagram and operation flow chart of the main function of the development process, the paper also encountered problems and solutions are discussed. The system functions of the main transfer query line query and site search function, not only can show the results of the query, but also to the electronic map display based on userselected line, to make the system more intuitive.
