此版本引入了一種新的權(quán)限模式，如今，用戶可直接在運行時管理應(yīng)用權(quán)限。這種模式讓用戶能夠更好地了解和控制權(quán)限，同時為應(yīng)用開發(fā)者精簡了安裝和自動更新過程。用戶可為所安裝的各個應(yīng)用分別授予或撤銷權(quán)限。
對于以 Android 6.0（API 級別 23）或更高版本為目標平臺的應(yīng)用，請務(wù)必在運行時檢查和請求權(quán)限。要確定您的應(yīng)用是否已被授予權(quán)限，請調(diào)用新增的 checkSelfPermission() 方法。要請求權(quán)限，請調(diào)用新增的 requestPermissions() 方法。即使您的應(yīng)用并不以 Android 6.0（API 級別 23）為目標平臺，您也應(yīng)該在新權(quán)限模式下測試您的應(yīng)用。

偷懶的方法：

工程目錄下-->app/buld.gradle --> targetSdkVersion 22 目標版本<23 指向Android 5.0 這樣系統(tǒng)就
不會檢測運行時權(quán)限 但畢竟這是偷懶的方法 說不定那天Google 大大不支持這種兼容性的套路 不就傻眼了 所以
該適配還是要適配滴
