Design And Implementation Of News Client Based On Android System

With the progress of science and technology, the mobile phone is no longer a simple communication equipment, and gradually tends to become intelligent, customized and security. With the growing maturity of 4G technology and the popularity of mobile devices, mobile internet has become the focus of attention and become the mainstream of future development. As the most widely used mobile terminal, mobile phone plays an important role in the future mobile internet.

With the advantages of fast to process, the use of mobile phones has become people's daily habits to pay attention to the latest information. Market share of android system is relatively large, and android system naturally becomes a platform for many applications.This topic is that design and implementation of news client based on android system. In this paper, the system is divided into two parts: the part of server and the part of client.

Apache Tomcat7 provides server interface procedures in order to simulate analysis of JSON data. The official solution Gson is used to resolve JSON data in this project.In this paper, the system uses object-oriented method to be analyzed.First of all, the specific requirements of the system are analyzed. Then use UML to establish the case model and function model of the system based on MVC in detail, and the structure of C/S system is used to implementation of view layer, data persistence layer and business logic layer. At last, the function and security of the system are tested. It shows that the design of the system is up to the expected goal. This system can complete various tasks such as news browsing and so on.
