Title        Design and Realization of a music player  based on Android platform                                   

Abstract Today's society is developing more and more rapidly, and people's rhythm of life is getting faster. Along with the popularization of mobile phone, people’s requirements of mobile phone software are also higher and higher, this paper mainly discussed the design and implementation of the music player on Android system. Android is a Java based system, which is a lightweight open source mobile phone operating system and running on the Linux kernel. The music player in the paper is carried out by using Java language and Eclipse development tool code. At the same time, the detailed design process, function flow chart and operation interfaces are given. The paper also discussed on the problems in the development in detail. The music player not only has basic functions such as play, pause, last song, next song, but also has lyrics display function. In addition, the player has some friendly settings, such as the songs mode, pause on incoming/outgoing call, and interface theme selection. The player’s performance is good, and it can run independently in Android system.
