Android OS其(qi)實(shi)是谷歌領銜的(de)(de)手機(ji)聯盟開(kai)(kai)發的(de)(de)一個移動設(she)備，主要是智能手機(ji)和平(ping)板電腦的(de)(de)操(cao)作系(xi)統(tong)(tong)(tong)，而4.0則是系(xi)統(tong)(tong)(tong)的(de)(de)版本號。因為安卓(zhuo)系(xi)統(tong)(tong)(tong)平(ping)臺(tai)具有(you)開(kai)(kai)放性的(de)(de)優勢，所以(yi)許(xu)多的(de)(de)開(kai)(kai)發商都可以(yi)通過這個平(ping)臺(tai)來(lai)設(she)計(ji)定制(zhi)第三方(fang)手機(ji)操(cao)作系(xi)統(tong)(tong)(tong)。

基于(yu)Android OS 4.0的意思就是(shi)(shi)手(shou)(shou)機的(de)(de)(de)系(xi)統(tong)(tong)(tong)設計(ji)是(shi)(shi)在4.0版(ban)本的(de)(de)(de)的(de)(de)(de)基(ji)礎下改(gai)造出的(de)(de)(de)第(di)三方(fang)系(xi)統(tong)(tong)(tong)。具體也就是(shi)(shi)說一些手(shou)(shou)機廠商(shang)或(huo)者個(ge)人開(kai)發者在得(de)到Android 的(de)(de)(de)代(dai)(dai)碼(ma)之后，通(tong)過(guo)修改(gai)一些代(dai)(dai)碼(ma)來增(zeng)加(jia)或(huo)者刪(shan)減(jian)某些功能(neng)來形成一個(ge)新的(de)(de)(de)操作系(xi)統(tong)(tong)(tong)，這些新的(de)(de)(de)手(shou)(shou)機操作系(xi)統(tong)(tong)(tong)擁(yong)有自己的(de)(de)(de)設計(ji)和功能(neng)，比(bi)如小米(mi)系(xi)統(tong)(tong)(tong)、錘子科技(ji)系(xi)統(tong)(tong)(tong)、百度云系(xi)統(tong)(tong)(tong)等眾多第(di)三方(fang)手(shou)(shou)機系(xi)統(tong)(tong)(tong)都(dou)是(shi)(shi)在安卓(zhuo)系(xi)統(tong)(tong)(tong)的(de)(de)(de)基(ji)礎下改(gai)造而成的(de)(de)(de)。

這些第三方的(de)(de)手機(ji)操作(zuo)系(xi)統除了可以下(xia)(xia)載(zai)官網上(shang)的(de)(de)相關應用(yong)(yong)程序之(zhi)外，還兼容其它(ta)的(de)(de)安卓APP應用(yong)(yong)軟件，所(suo)以這些手機(ji)還可以到安卓APP應用(yong)(yong)商(shang)店下(xia)(xia)載(zai)安裝有趣的(de)(de)移動應用(yong)(yong)。
