Design And Implementation Of The Laboratory Teaching Auxiliary System Based On The Android

Along with the rapid development of modern computer and network communication technology, the mobile terminal products based on the intelligent operating system will gradually replace the original manual computer working even become the important tools of our life. Google’s Android operating system was published in 2007, it is an open source system which is based on Linux mobile operating system and its main feature is the strong scalability with obvious layered architecture design and it can be widely used in various fields.Mobile intelligent system has heavily promoted the development of mobile electronic products, like smart phones, multimedia player, electronic navigation and other embedded terminal equipment in every aspect of our lives. Education from the traditional manual management gradually developed into a computer, but still can’t meet the demand of modern education teaching management. Combining education and intelligent terminal, this paper puts forward a kind of auxiliary teaching system and implementation scheme based on Android platform of the design.The scheme is a combination of computer information management rapidity and the intelligent terminal operation flexibility, implemented the teaching system used in laboratory teaching circumstances.First this paper introduces the related theory and technology points, focus on the characteristics of the Android system. Second in the teaching system based on the analysis of the demand, the system has carried on the detailed architectural design, function module design, database design and function design of the interface. This system is an application based on Android mobile platform, suitable for Android mobile devices and studying how to use Android mobile devices to realize the sharing, distribution, real-time interactive of electronic documents, graphics, images, audio, video and other multimedia resources in the laboratory teaching environment, especially suitable for the more flexible multimedia auxiliary teaching experiment environment. Then according to the requirements, based on WIFI environment, under the Eclipse we use Java language, Android SDK, SQlite and SQL Server database system to design. This system use three layer architecture to overall develop, the user interface layer, business logic layer and data model, hierarchical design for future system version upgrade provides a larger space. In addition, the system also takes the number of users into consideration, allows multi-user multi-tasking multi-stage concurrent operation, implements Java multithreading and the application of advanced concurrency library, thus greatly enhance the experience and flexibility of the system. The system also uses the third party Android SDK to achieve the function of video processing module. Compared with other similar products on the function, this system is more adapt to the application of laboratory teaching environment. Finally, according to the standard of software testing, the system has carried on the detailed function module test, the results accord with test standard.The main function of this system include:user login, registration module, mobile multimedia information management module, file upload, file download, file browse module, multimedia communication module and experimental evaluation module. For some kinds of inflexibility of information management, resource sharing, interactive teaching of laboratory teaching in colleges, the paper proposed scheme that combined the Android mobile terminal equipment with the mobile multimedia teaching resources. The biggest advantage of this schema is that through mobile multimedia teaching resources, get rid of the paper experiment resources and PC electronic resources to solve fixed mode of students experiment reference, make up the hysteresis of information sharing, resource use and the teaching interaction in teaching activities, let the participants can experience the advantage aspects of convenient operation and timely interactive in teaching and learning process.
