Abstract:For now, the bus is most people travel the preferred mode of transport. And with the continuous development of era, the rapid scientific and technological achievements, with mobile phone penetration increased, function of the ease of use and increasing rapid ascension, the mobile phone has became one of the main ways to get all sorts of information when people living and working . With the aid of wireless network, people can use the mobile phone anytime and anywhere to query, want to get bus information can enjoy better public transport query service than ever before. 

　　　This design development is based on the Android platform, using the MyEclipse as a development tool, written in Java language, supplemented by Android related controls, choosing SQLite as database, SQL language is applied to implement to the operation of the database. Adding bus information to system database by getting through network and the actual measurement, ensure data is accurate, the main implementation of system functions including line query, site query and transfer query.
