摘要现在，人们的生活已经离不开移动终端设备。传统的移动名片本存在联系人数据存储形式单一，联系人名片信息内容不够丰富等缺点。随着移动互联网和云计算技术的不断发展，云计算平台推出各种服务，云存储是其提供的重要服务之一。本文设计了一个基于云平台和富媒体的移动名片本系统。

本文设计的移动名片系统能够实现对联系人名片的创建、查看、修改、删除、分享等管理功能；实现联系人名片的本地存储和云端存储；此外，还能实现联系人名片的二维码生成和扫描。本系统基于Android平台开发，使用Java作为开发语言，同时使用了百度对象存储SDK、ZXing SDK等工具包。系统具有操作简单、实用性强等特点。 

本文首先介绍了移动名片本系统开发的背景、研究目的及意义。接着，简要介绍了开发系统必要的关键技术。然后，对系统架构和功能模块进行设计，并对系统各功能模块的设计和实现进行了详细的介绍。最后，总结了系统开发过程和需要完善的不足之处。86613

AbstractNowadays, mobile devices become an indispensable tool to people's life。 Traditional mobile business card has many shortcomings, such as a single form for storage, non-abundance content and so on。 With the development of mobile internet and cloud computing, cloud computing platforms have launch a variety of services。 And With the development of mobile Internet and cloud computing, cloud computing platform to launch a variety of services, cloud storage is one of the important services of these platform。

In this paper, we design a system of mobile business card based on cloud platform and rich media。 This system can realize many management functions that cards' creating, viewing, updating, deleting and sharing etc。 And it can achieve the local storage and cloud storage of business cards。 It can also generate and scan the two-dimensional code of the cards。  The development of this system is based on the Android platform。 And we used Java as a development language and several tool kits which are Baidu Object Storage SDK, ZXing SDK and so on。 The system is simple and practical。

At first, the paper introduces development background, purpose and meaning of this topic。 Secondly, it briefly introduces some key technologies of system development。 And then, it describes the design process of system architecture and functional modules。 Furthermore, it describes the design and implementation of all these modules in detail。 Finally, it summarizes the system development process and the shortcomings that need to improve in future。
