android - 华为P9 / 华为P9 plus 安装apk之后无权限.

Question

机型: 华为P9、华为P9 plus

系统版本:EMUI 5.0 基于 Android 7.0

请问一下, apk同为同一市场下载,在安装之前有提示相关信息,安装完成之后,默认所有的权限开关是关闭状态的.就算手动开启 "信任该应用" 之后SD卡读写权限还是没有开启.请问是怎么回事.请查看一下配图.

正常其他apk的安装截图.

不正常的截图

I guess the target version of your app is greater than 22.
After sdk23, some dangerous permissions need to be applied dynamically, but if the app targetSDKVersion is less than 23, you can still get the permissions you need from the manifest. Vice versa, You need to apply for permission dynamically.
