As the 3G work’s largescale construction and the smart phone’s rapid popularization, mobile inter age has e with a smile. Since the issuance of the world’s first mercial mobile phone in 1983, the total number of global mobile phone users has been more than billion in the past less than 30 years. Consumers demand more and more mobile phone’s performance in business and entertainment, which has made mobile phone the portable terminal for business and entertainment day by day. Being motivated by hardware, users’ needs on mobile phone software’s function goes increasingly high. Android system is updating to satisfy the needs. Therefore, the development of mobile multimedia technology has inevitably bee the hot spot. Android is the open source mobile system published by Google in 20xx. For the reason that its openness is superior to other closed mobile system, anyone can rewrite all functions in the mobile system as he or she like, which has made more and more people pay attention to this operating system. This design is a music player using Java as the basic programming language, which is based on Android operating system and above version, and can be operated by the standard database SQLite that offered by Android system. Though this design is not big, it contents Android’s most programming technology. Its favorable user interface can conduce to the realization of its basic function in music controlling (start, pause, switching between up and down music, lyrics synchronized display) and play mode controlling (single play, single cycle, random play and all cycle). Besides, it also realizes the function in song including search, add, delete and so on. Key words: Android。 Google。 music player。 Java。 mobile inter 內(nèi)蒙古科技大學(xué)畢業(yè)設(shè)計說明書（畢業(yè)論文） IV 目 錄 摘 要 .........................................................................................................................................
