This article is in the Android system, music player application on the design and implementation to discuss the process through which to further study and application of Android, so the future development of personal sense. Music player of this paper uses Android open-source system technology, the use of Java language and Eclipse development tools for the preparation of the player code. At the same time gives a detailed system design process, some interface screenshots and the major function of flow, the paper also encountered in the process of development problems and solutions were discussed in detail, the music player, set play, pause, stop, on one, the next song, lyrics display, background play and other functions, good performance, in the Android system can run independently. MP3 is a compressed audio file format, as the player is limited to the application layer of the program, so not to go into the specific compression algorithm. Experiments show that,
