Design And Implementation Of Goods Sharing System Based On Android Operating System

In recent years, with the continuous development of the mobile platforms, we can get information more convenient through a smart phone, and the development of mobile client platform based on a variety of smart phones has a hot topic of the major e-commerce company.We will have a lot of unused goods with the continuous improvement of people’s living standards, and the problem of building energy-efficient and environment-friendly society is grandually concerned about.The system aims at solving the unused goods publish, share and instant messaging and other issues in order to satisfy the demands of users.Android with real open-source software is first developed by Google to serve mobile devices, the system architecture of the platform consists of the application layer, application framework layer, system layer of the runtime and the Linux kernel layer.In this thesis, we study on android and its application in unused goods sharing system.The thesis is constituted of four parts, a technical brief, requirements analysis, algorithm research and system implement. The first part is a brief introduction to the Android application components and Socket network communication technology used in the systemdevelopment process. Next, the system requirement based on object oriented menthod is discussed in detail. And user case models and the basic functions and database. Subsequently, the thesis introducts some algorithm like matching algorithm and recommendation algorithm, which are commonly used in this class of systems, then puts forward applications in this system. Finally, the thesis has discussed the produce design and implementation of the unused goods sharing system, which based on Android mobile platform, including the implementation of the major modules, and describes the running interface of system on mobile phone platform.Finally, the thesis closes with a summary the obtained result as well as an outlook on possible research avenues.
