In the rapidly changing electronic products life, the major smartphone manufacturers of electronic markets are still bright stars. Such as Nokias Symbian system, Motorolas Linux system, but Googles Andriod open source system with its simplicity and ease of operation must be the future leader in the field of smart phones. This paper is about the development and application of a music player which based on Android after analysing the platform development course and the technical characteristic, as well as the current domestic and foreign development present situation. First it makes a detailed requirements analysis, business process analysis and data analysis of the media player, it also gives a detailed system design plan. After the design is directed to a system interface diagram and the main function of the realization of the code, at last it achieves some of the problems encountered in the system and discusses the extension of the system. 【key words】: Android; open source; Linux; music player  目 录 TOC \o 1-3 \h \z \u 1．引言 1 1.1 项目开发的背景及环境 1 1.1.1 项目开发背景 1 1.1.2 项目开发环境 1 1.2 项目意义 5 1.3 小结 5 2．系统分析 6 2.1 需求分析 6 2.1.1 总体目标 6 2.1.2 具体目标 6 2.2 可行性分析 7 2.2.1 市场可行性 7 2.2
