Android Question Android 4.4 restricted user write to SDexternal

[padvou]

Why does the following code fail:

File.Copy(File.DirInternal ,"client.db", "/storage/extSdCard/Android/data/uop.unicollect/files", "/unicollect/DBbak/" & "bak_client.db")

The External SDcard location is correct since the code runs correctly with the main user.

Yes,
I've used the code you mention. All work fine as long as the user is not restricted.

I also tried this:

Sub SaveStringExample
Try
    File.WriteString("/storage/extSdCard/Android/data/uop.unicollect/files/unicollect/DBbak/", "String.txt", _
        "This is some string" & CRLF & "and this is another one.")

Catch
Log(LastException.Message)
Msgbox(LastException.Message, "ERRor")
End Try
End Sub

And get this exception:

libcore.io.ErrnoException: open failed: EACCES (Permission denied)
