Design And Implementation Of Mobile Terminal Information Query System Based On Android

Researched on the current situation of the development of the research on mobile phone operating system and compared at home and abroad about Android research content,the mobile terminal based on Android information query system is designed and implemented.The background and significance of the research topic are firstly introduced in the paper.It elaborates the current situation of the development of the mobile phone operating system and mobile terminal based on the Android applications.the concrete research content and the framework of the task are proposed.Through the study of relevant theoretical knowledge,we know the need of the language and technology etc.to develop the system.During the detailed design of the system and the realization process,the information query system is divided into two parts: web client and mobile terminal.And these two parts communicate through the network.The Web client system includes web server and the database used to store the information,and the mobile terminal over a wireless network can realize information access and ultimately achieve the information query.In this article,the two parts,Web terminal and mobile phone terminal,are tested.The Web client mainly tests the administrator login module and data management module.And also the stability of the Web client is tested.Test results show that the administrator login module and data management module of the Web client are found no abnormalities,and the system of Web client is stable.When the test function of mobile phone terminal,mainly from information inquiries and information used two modules were tested.The test results show that no abnormality in mobile terminal module testing,the system can be normal operation.The system which uses technologies of Java,Database andJava Web to fulfill the design of the entire system contains computer technology,wireless communication technology and mobile platform technology,and realizes an entire structure from the client,network to server-side.With the system testing,the software can successfully achieve the functions.
