Design And Mplementaion Of Traffic Monitor Based On Android

With the rapid spread of Android phones and operators’high-speed networks, more and more mobile phone users have the chance to surf the Internet on their Android phones. Under such circumstances, traffic overrun and some applications’background network connections bring economic and mental losses to Android phone users. To solve these problems and to help phone users use a safer phone, the author designed and implemented a traffic monitor application based on Android system.This thesis describes the design and implementation of the traffic monitor application. The first chapter introduces the backgrounds, sources, goals and importance. It indicates the tasks of this thesis and teases apart the whole thesis. The second chapter introduces the technology principles that will be used. The third chapter creates the target user’s persona and details the product’s requirements from the users’point of view. The forth chapter finishes the summary design of traffic monitor. It details the functional modules with user case diagrams and details the user interfaces with user interface design diagrams. The fifth chapter introduces the core modules’ design and implementation with class diagrams. The sixth chapter introduces the quality assurance phase. The quality assurance phase includes requirements validation and robustness testing. Some screen shots of traffic monitor are shown in this chapter. In the last chapter, problems in design and implementation are shown, and the future improvements are pointed out.In this application, several kinds of user interfaces are designed to show traffic usage, SMSs from operators are used to adjust the local records, iptables and task killer are used to block connections. During the period of designing and implementing, patent about traffic notifications has been applied. Above all, the traffic monitor has been released to millions of users as a commercial product.
