[h2]13900001 Operation Not Permitted
Error Message
Operation not permitted
Description
The operation is not allowed.

The caller does not have the permission to access the URI or path.
Solution
-
According to the current system's access control mechanism, an application cannot use a URI shared with other applications.
-
According to the running mechanism of system Picker, a URI obtained through Picker has only temporary permission. If continued access is required after the application exits or the device restarts, process it according to the permission persistence procedure.
