【正文】 and promote the innovation and development of related industries related fields . Now we have to admit that has entered the mobile era, mobile application development in the ascendant, where the application on the Android platform from which to develop its unique advantages emerged as an important hot research field. Due to the flexibility and stability of the Android system, more traditional applications gradually migrate from the puter to the phone. As we all know , the traditional OA (Office Automation Office Automation ) has made great progress and mature , such as contacts , document management, document processing, scheduling , notifications and other functions have been perfectly realized , efficient and intelligent bination of the Android platform OA system , OA system with the traditional functions ported to smart phones, allowing users to carry handheld mobile office anywhere , to improve office efficiency and reduce unnecessary consumption of great significance and practical value. In this paper, the use of Javarelated technologies, bined with the characteristics of the Android platform for mobile OA’s actual needs and business processes are analyzed, mainly to plete the design of a mobile OA based on the Android platform, focusing on the development process and detailed implementation, but also describes the basic knowledge and key technologies involved in mobile OA system.
