Design And Implementation Of Instant Messaging Application Based On Android Platform

With the rapid development of computer technology and network communication technology,the application of instant messaging system has also been all aspects of the use and dissemination,the more typical QQ,online,MSN,their appearance makes the communication model once a network New innovation of the carrier,while reducing the cost of communication at the same time,greatly improving the frequency and efficiency of people to communicate.Instant messaging is a relatively prominent and successful application direction in Internet applications.Its development track has experienced simple messaging from single platform,audio transmission to multi-platform,heterogeneous network,video transmission and image transmission.Gradually includes the social chat,mail,business management,online games and other fields,especially in recent years the rise of smart phones,making the use of instant messaging has become increasingly widespread and indispensable.However,the current mobile intelligent terminal instant messaging applications there is a certain use of restrictions and security risks.The use of restrictions mainly from the mobile terminal operating system is relatively closed and different applications used by the communication protocol is not the same,resulting in different client applications cannot communicate,security risks will threaten the user's private information and instant messaging Pass the message.The paper will focus on these two aspects of research technology,the use of XMPP communication protocol,the agreement has a strong scalability,allowing heterogeneous instant messaging applications between the mutual communication;the use of independent servers,and refused to external access,Thereby enhancing the security of the system,to avoid thirdparty service providers to disclose user information.The entire instant messaging system uses the C/S design pattern,the use of real-time collaboration server Openfire as the server side of the system.MVC uses the design pattern to develop the system's Android mobile client.The client mainly contains six modules,namely login module,registration module,main interface module,friend management module,chat module and function setting module.After a reasonable deployment,the entire instant messaging system will focus on enterprise management as the center,the effective realization of enterprise personnel management,departmental internal chat,enterprise information release and other functions,can greatly improve the efficiency of enterprise management.
