【移動(dòng)應(yīng)用開(kāi)發(fā)技術(shù)】怎么在Android中使用vitamio插件實(shí)現(xiàn)一個(gè)視頻播放器

這篇文章給大家介紹怎么在Android中使用vitamio插件實(shí)現(xiàn)一個(gè)視頻播放器，內(nèi)容非常詳細(xì)，感興趣的小伙伴們可以參考借鑒，希望對(duì)大家能有所幫助。Android是一種基于Linux內(nèi)核的自由及開(kāi)放源代碼的操作系統(tǒng)，主要使用于移動(dòng)設(shè)備，如智能手機(jī)和平板電腦，由美國(guó)Google公司和開(kāi)放手機(jī)聯(lián)盟領(lǐng)導(dǎo)及開(kāi)發(fā)。項(xiàng)目結(jié)構(gòu)代碼：MainActivitypackage
