這篇文章主要介紹了安卓Android6.0權(quán)限動(dòng)態(tài)獲取操作,結(jié)合實(shí)例形式分析了Android6.0針對(duì)權(quán)限的動(dòng)態(tài)獲取、授權(quán)等相關(guān)操作技巧,需要的朋友可以參考下

本文實(shí)例講述了安卓Android6.0權(quán)限動(dòng)態(tài)獲取操作。分享給大家供大家參考，具體如下：

眾所周知 , 安卓6.0現(xiàn)在運(yùn)用的越來(lái)越廣泛 , 因?yàn)橄鄬?duì)于之前的幾個(gè)版本 , 對(duì)于用戶權(quán)限這個(gè)概念確實(shí)不是很重視 , 而6.0 之后 , 為了提升用戶的操作安全性 , 運(yùn)行時(shí)權(quán)限誕生了, 就是在用戶運(yùn)行軟件的時(shí)候動(dòng)態(tài)獲取所需要的權(quán)限 , 下面跟大家分享一個(gè)我的代碼案例 :
