Android Question Error file copy from DirAssets

[nicolino33]

Hello, this is the problem:

-----here ok, the file is found----​

If File.Exists (File.DirAssets, "db1.db") = True Then
Msgbox("ok","")
End If




If File.Exists (File.DirDefaultExternal, "db1.db") = False Then
-----here ok, the file is NOT found----
Msgbox("db1.db","non esiste")

-----here the copy error, the file is not found! ----
File.Copy(File.DirAssets, "db1.db", File.DirDefaultExternal, "db1.db")
End If

Why?
