Hi there,
when you select "manually specified" as the directory for data storage, you
are likely going to mess with issues wit Access Permissions.

In all Unix/Linux-like file systems (and Android is in effect a variant of
Linux), when a directory is created, access to it is granted only for the
user who created it (the "owner"); Separate permissions are used for
reading, writing and executing programs from it; also, the same permissions
can be extended to the users belonging to the same "group" as the owner, or
to "other users" (for more info, you can just check some basic tutorial
like this: https://www.geeksforgeeks.org/permissions-in-linux/ : there are
plenty around the internet)

Basically, the error shown by OsmAnd when you select such a directory is
happening because permissions to access that particular directory have not
been set properly.

In order to solve it, you would need to edit the permissions with an
advanced file manager, i.e. Total Commander, or with the chmod command
through a textual Console session, if you are brave enough, by setting them
to "rwx rwx rwx" (aka "777").

Problem is that also an advanced file manager or Console might have limited
access to the directory, if you're not accessing as a root/super-user,
hence the limitations experienced by many people.

My personal choice for OsmAnd would be setting the storage to "external 1"
(storage partition integrated into the device's memory support), of it's
bug enough (i.e.128GB) or "external 2" (partition on expansion Micro-SD
card), if available. In that case, OsmAnd itself should ask for access
permission (just grant it), but more limitations may be present due to
vendor-imposed "security" choices.

Hope this helps,
Max
