Open Android mobile device platform developed rapidly in recent years, a large number of smart phones of using this platform have been published, were widely praised by the market, Android platform-based application development has gradually become a hot research of compter software.OA (office automation) system development so far, has entered the mobile age,the documents,address book, calendar, file management,notification and other functionson on the original OA system to migrate to mobile phones gradually,OA system in the near future will allow users anywhere handheld office can be foreseed.Based on making a large number of researches and analysis on the Android platform, author propose the topic of using of the Android smart phone platform’ efficient and intelligent features to achieve the OA system, it improve office efficiency will be important and practical value.Main job of this thesis is that to be completed an Android-based micro-OA system’s needs analysis, overall design, outline design, code implementation, testing and release, the main contents of the thesis are as follows:First, a brief analysis of the Android platform architecture, focuses on the basics of the Android platform,the basic components of Android framework, API of Android platform, and some of the key technologies of achieve OA system on Android platform;Secondly, the authors conducted a lot of research work on the typical OA system for mobile object-oriented requirements analysis, through modeling language tools to analyze and building model,and get the movement OA system’s architecture and basic functions;Again, to use of object-oriented analysis and design methods, including the system object model analysis, system module division, MVC model of system architecture design, propose the Solutions of OA system base on Android platform;Finally, to give of the Android-based micro-OA system’s the detailed design and implementation ways, including concrete realization of the various functional modules and simulator run results, and for the system to achieve the key technologies involved in detailed discussions.
