How do I grant permission to write on android?

Android 11 introduces the MANAGE_EXTERNAL_STORAGE permission, which provides write access to files outside the app-specific directory and MediaStore . To learn more about this permission, and why most apps don’t need to declare it to fulfill their use cases, see the guide on how to manage all files on a storage device.

On the Settings > Privacy > Permission manager > Files and media page , each app that has the permission is listed under Allowed for all files. If your app targets Android 11, keep in mind that this access to “all files” is read-only.
