The Design And Implementation Of Android Application Based On Enterprised Social Networking

With the development of the enterprise,the complication of the organization and decentralization of geographical location greatly reduce the SAP efficiency in communication which leads the enterprise to seek for a platform where instant communication and collaboration is possible.Furthermore,the management model featuring social mobility makes it possible to decrease the cost of communication in the enterprise and the Application,with the aid of portable mobile devices,provides the information flow and clear guidance,which will fully satisfy the company's demands.With Jam application of SAP as the example,the thesis studies the following.Firstly,the Hybrid Mode of developing Jam App based on its business requirements.It substitutes WebView for the Web page with general uses,little demand in function and interaction Performance,and the native system API in the light of Jam in various occasions and the data of OData protocol(Open Data Protocol).Other Web pages apply the Hybrid developed by the native resources.As a result,the application will greatly meet the enterprise's changing needs in applications and gain better operational performance.Secondly,for ordinary Application of enterprise communication,its core functions as “Community building”,“Sharing social status” and “Perpetuate data base”,all involve a large number of pictures and words,resulting in excessive data consumption and slow loading speed.Therefore,the thesis,based on network situation,data safety and different media of buffering,puts forward a buffering system in dynamical network environment to deal with large graphic data.What's more,it builds the “memory-file-network” three-level buffering in order to solve the out of memory caused by images of high resolution as a result of SQLite buffering under OData protocol.Lastly,Implement the Hybrid Enterprise SNS App Jam with high quality cache.The thesis analyses the functions,architecture and module design of Jam and how the core module of dynamical buffering operates with the help of group communication.It tests all functions with the means of the black box,and the effectiveness and loading performance of Jam buffering in different network environment,which proves the correctness of the buffering system and enhances its operation significantly.Jam was released on Google Play in October,2005 and had more than 10 million users in North America by January,2016,which testifies the theories in return.
