技术图纸及程序仿真及源代码需要联系qqAndroid手机音乐播放器的应用开发 Application and development of Android mobile phone player 学生： 班级： 学号： 学部： 专业： 指导教师： 职称： 工作单位： 毕业设计（论文）完成时间： 自 年 月 至 年 月 关键词：Android；开源系统；Linux；音乐播放器 ABSTRACT The pace of life in todays society, with more advanced hardware mobile devices for mobile devices, people more and more is also high, the requirements from the previous pursuit to pursue the visual technology, therefore, also gradually improve the system requirements, the paper mainly is to take on a music player from system design and realization of the application is discussed. Take the system is an open source; it is based on the operating system, use the Linux music player of the Android open-source system technology, using the Java language and editing tools for players to Eclipse. Presents the detailed design process, the part of the system and the main functions of operation interface diagram of height, this paper also flow process problems and solving methods are discussed in detail, and the music player episode, play, pause, stop, form, next, volume adjustment, lyrics display functions, such as performance is good, can operate independently in the Android system. This player has access to the file browser phone functions, songs and played pattern, open and close condition of friendly words. MP3 name is MPEG Audio Layer-3, is a kind of sound files compressed format, because the players to explore, so the application procedure for specific compression algorithm not probe.
