Design And Implementation Of Communication Management System On Android Platform

By now the smartphone, especially the Android smartphone is more powerful than before. And more and more people use it in their daily life. However, there are some problems which are consequent on it, such as the convenient use of Contacts, the leaking of user privacy and the communication harassment. Therefore, it is important to do the research about convenient management and protection of communication on Android platform. This thesis describes relevant solutions and designs the Communication Management System on Android platform.In this thesis, at first it introduces the background, the significance and the content of this research. It also introduces the relevant technologies of application development on Android platform. Then it analyses the user requirements, and divides the functions to night modules. They are network module, register module, software update module, Contacts backup and restore module, quick dialing module, call block module, message filter module, privacy cleanup module and private space module. After requirement analysis, it starts the summary design process. It designs the system as a whole by the method of MVC and separates the data display from the data processing. In the design of every module, it follow the principle "low coupling and high cohesion". It makes the inter-module relation clear. Base on summary design, this thesis describes the design about every module. It analyses the module handling mechanism and the process flow. It also describes the inner algorithm, classes and interfaces. At last, it tests this system and shows the effect diagrams. After three times of detailed tests, this system passed most of the test cases and its veracity and stability are confirmed.The development of this Communication Management System has already finished. It has been putted into commercial and provided the services of convenient management and protection in communication for Android smartphone users.
