Android is an open source system, it is based on the Linux operating system, the music player of the paper adopt the Android opensource system technology and take advantage of the Java language and editing tools to Eclipse players. Simultaneously, it gives the detailed design process, the part of the system and the main functions of operation interface diagram of height, the paper has detailed discussions about problems and solving methods in flow process, the music player covers episode, pause, stop, up, next, volume adjustment and lyrics display functions etc, because of good performance, it 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. The full name of MP3 is MPEG Audio Layer 3 and a kind of sound files pressed format. Because the players is only limited to the exploration of applied program, it doesn’t study the specific pression algorithm. Key Words： Android 。 Open source system 。 music player III 摘要 .............................................................................................................................................
