基于安卓的音樂播放器開發(fā)-畢業(yè)論文

1、[摘要摘要]roid平臺是Google研發(fā)并推出的的移動平臺，包含操作系統(tǒng)等各方面，代碼開源。這有助于安卓工程師完成開發(fā)過程中減少工作量，縮短周期，快速完成開發(fā)任務(wù)，同時用戶能夠最大化享受各種層接不窮的安卓應(yīng)用，這是安卓應(yīng)用占據(jù)很大部分市場的原因。在今天這個發(fā)展迅速的新時代，音樂播放器的開發(fā)越來越多，這個項目的開發(fā)也的確為很多人帶來了便利和娛樂。roid目前在中國市場的發(fā)展前景非常好，中國智能手機用戶十分多，安卓主打自由開放系統(tǒng)，合適大

2、部分人群，普通安全要素盡管沒有IOS安定易用，但發(fā)展前景仍然令人非常喜悅。隨著人們的水平持續(xù)提高，越來越多的人開始有各種各樣生活，也有更多的多樣性需要，而roid以其獨特的魅力奪取大多數(shù)人的鐘情。在這樣一個階段，音樂播放器的應(yīng)用也是特別的壓力。音樂播放器滿足廣大部分人的需求，結(jié)合主流播放器的基本功用，進行一定創(chuàng)新，才能為大部分人才能帶來極致音樂享受。音樂播放器的基本功用完成是主流音樂播放器的基本功用，差不多符合公眾對音樂播放器的要求。除

3、此之外，播放器還提供了下載功用和直播，立體聲道等新功用。滿足各類用戶的需求，帶來前所未有的新鮮感。[關(guān)鍵詞關(guān)鍵詞]roidroid；Java；音樂播放器Abstract:roidplatfmisGoogleresearchdevelopmentlaunchofthemobileplatfmincludingtheoperatingsystemotheraspectsofthecodeopensource.Thiswillhelprews
