Various techniques are adopted in the process of implementation such as Android basic components, Android data storage and access technology, Android positioning technology and instant message pushing technology. Taking the MVC pattern as reference, the software separate the display and the logic to reach good scalability. To meet encapsulation and modulation principle, the project is divided into five modules:functional modules, communication module, storage module, image processing module and audio processing module.The author has independently implemented five functional modules. They are contacts module, circle module, part of the chat module, account module and the other modules; Besides, the author designed and implemented the communication module, data storage module and image processing module. After system testing and screen adaptation, the app has been deployed to IBM enterprise mobile applications platform.Currently the app runs well.
