The Design And Development Of Online-examination System Based On Android Platform

In the major colleges and universities,the examination is a very important part o f the school students to learn the quality of control and knowledge of the degree of mastery,in order to determine the student knowledge and teaching quality testing.Aft er many years of innovation,the examination model by the original teachers to work out the title,the preparation of papers,print papers this time-consuming consumption of the traditional model,into the various colleges and universities now widely used on the machine test mode.At the same time,the rapid development of network technology,mobile intelligen t equipment,rapid innovation,the pace of the public also accelerated.To Android for the system to move the emergence of intelligent devices,a large extent changed the original way of life,both at work or learning have become more convenient.This arti cle is mainly for the traditional sense of the cumbersome examinations and geographic ally restricted online examinations,thus the design and implementation of an Android platform based on the online examination system.The system to the Android system f or the terminal,to provide free from the geographical restrictions on the online exami nation,automatic marking and other related services,students in the mobile network(or WiFi),anytime,anywhere to complete the examination,with simple,flexible and c onvenient features.The android platform is based on the C/S architecture,which is divided into clie nt and server.The client is mainly responsible for the interaction and user,the user c an operate directly on the client side,the application of the Activity component as the user interface,components and through Intent for different jump of the page.Server side is mainly responsible for receiving the request from the client users,thereby to a ccordingly,and send instructions from the MySQL backend database,extract the infor mation content according to user’s requirements within the database,the content of fee dback to the client users.Client and server through the data stream in the customer s hows the flow of the whole system inside information,database by setting different da ta tables to user information storage operation and test related content.The article mainly divides into six chapters,the first chapter is to investigate test environment at home and abroad and discussed,and the development of the Android system background detail.The second chapter is the test procedures required in the p rocess of development and design tools,including the Android system,Java language,system architecture and database.The third chapter is the main content through the ap plication of the existing examination system and the software now market feasibility a nalysis,and the students access to test system requirements,on this basis to design th e software framework.The fourth chapter main content is a description of how the ap plication software design,including client and server specific development.The main c ontent of chapter five is about the application of software testing part of the narrative.Finally is the contents of the first five chapters summarize and expectations of future such applications.
