Abstract: With the development and application of 3G technology, mobile game, animation, audio or video, etc. become important developing trend of mobile value-added services. There are two common problems in current mobile applications. One is that the diversity of application type increases the complexity of application development; the other is that there is a huge job to make application adapt to various mobile terminals. Based on the ideas of traditional middleware and mobile middleware, this paper proposes the architecture design of mobile middleware for adapting multi-terminal and gives concrete realization of the core components, such as visual development environment, simulated operation engine, application generation engine and cross-equipments support engine. It makes the mobile application development easier and easier. At the same time, it can help mobile application automatically adapt to various types of mobile terminals, solves the key issues for terminal support to popularize mobile applications.
