在Android Q中引入了分区储存功能，在外部存储设备中为每个应用提供了一个“隔离存储沙盒”。其他应用无法直接访问应用的沙盒文件。由于文件是应用的私有文件，不再需要任何权限即可访问和保存自己的文件。此变更并有助于减少应用所需的权限数量，同时保证用户文件的隐私性。Android Q 更改了应用对设备外部存储设备中的文件（如：/sdcard ）的访问方式。

继续使用READ_EXTERNAL_STORAGE和 WRITE_EXTERNAL_STORAGE 权限，只不过当拥有这些权限的时候，你只能访问媒体文件，无法访问其他文件。如果Target SDK > 28，请在manifest中添加android:requestLegacyExternalStorage=“true”
