Mobile Terminals Based Xface Widget Application Development

With the rapid development of mobile Internet, the current mainstream mobile platform is MTK, Brew, Windows Mobile, Symbain, Android, and so on. Because these platforms are not currently occupy the market and is a platform for the mainstream operating system, software development for mobile phones which resulted in difficult to popularize, universal compatibility and poor range of issues. For this situation, at this stage of the more popular solution is Mobile Widget technology, xFace middleware is similar to the Widget Engine. Embedded software from the University of Electronic Science and Technology Engineering Center developed xFace platform engine is more than a lightweight cross-platform mobile runtime environment Widget, which provides a dedicated Web engine as a lightweight mobile desktop environment for developers to provide quick mobile application development platform.The thesis of background based on xFace engine and the Widget application development, application development is market-oriented positioning, development of applications for a supplier information management system,. Manufacturing industry to get supplies to information will extend to the mobile Internet, the vendor of this development the need for information management systems, is to explore the mobile Internet technology applied to production supplies, the convenience of customers through different mobile terminals not only a seamless Internet connection, and provides a platform to facilitate the work, to collect, evaluate, publish information and material suppliers to improve demand for goods search capabilities, save time and improve efficiency; the same time, the phone terminal, as suppliers material information release platform, achieve a similar effect of advertising, enhance material supply side and demand-side interaction. Papers focus on the application, the system discussed xFace engine related technologies, as well as database systems and back-office systems to build; focuses on the mobile terminal Widget application interface implementation. The application developed is characterized by: the entire system is based on Java ee architecture; database system design and related; xFace cross-platform, can adapt to different terminal capabilities; and supplier information management, user management, order management, evaluation and management; these module layout layout, asynchronous transmission, human-machine interface.Take into account market factors and the actual user experience, Widget application development for the entire period, according to the V model with software testing. This makes the mobile terminal based on xFace application development market, standardization, and easily in a variety of cell phone popularity. Fully explain xFace engine, reliable, cross-platform; the development of applications based on its scalability and broad market prospects.
