Design And Implementation Of Android Platform-Based Instant Messaging System

Since instant messaging systems appeared, such web-based real-time way which other online users to interact with, is favored by demanding real-time business and service industries with its convenient features. Traditional real-time communications applications are mostly realized in the PC side, but with the development of wireless transmission networks, and the introduction of intelligent operating platform provides a hardware foundation, mobile devices in real-time communications system has become the new 3G business highlights. In this paper, to solve the interaction between mobile device and PC instant messaging client, as well as a lack of unified communication protocol standards, analysis of the current status of research, design and realize an instant messaging system of Android platform-based using Jabber protocol.In this paper, adopt the management methods of software engineering, analyze the project requirements, complete the functional use case modeling, from the HTTP transmission, Jabber protocol analysis to each module of client to analyze, design of the proposed architecture of the system and the overall structure design, introduce key technologies of the application, establish a scalable model of conversation, use design methods of loosely coupled, realize instant messaging system of Android platform-based using Jabber protocol.After the test of the application, results show that the completion of the user registration system, registry, friends management, group management and information exchange, such instant messaging features have run smoothly, solved the problem of interaction among different instant messaging protocols , get a good user experience, the system has been used in actual projects.
