Listfiles error

[JDS]

Good morning,

I've got the following code:

File.Delete(Globaal.Map_Uren, Globaal.psFileToDeleteUren)
Globaal.psFileToDeleteUren = ""
Dim lListU As List: lListU.Initialize
lListU.Clear
If lListU.IsInitialized Then
lListU = File.ListFiles(Globaal.Map_Uren)
If lListU.Size>0 Then
        sNewFile = lListU.get(0)
   psFileToDeleteUren=sNewFile
....
end if

The situation is as follows:
The directory "Globaal.Map_Uren" contains serveral xml-files ("Globaal.Map_uren" = File.DirInternal & "/Uren"). These files are send and then the next file (and so on). At a certain point the directory (Globaal.Map_uren) is empty. But I check one more time to be sure "lListU = File.ListFiles(Globaal.Map_Uren)". At that point the application stops working. The strange part is that it works four (or more) times and when the directory is empty I get the following error:

lListU = File.ListFiles(File.DirInternal & "/Uren")
java.io.IOException: /data/data/lmmobile.jds.android/files/Uren is not a folder.

The same occures when I want to write quickly several files to this directory by pressing a button.

I guess that Globaal.psFileToDeleteUren is an empty string and then the folder is deleted. You should check File.Exists to make sure that there is a folder.

I've updated the code-segment.
The first value in the list gets send and, when returning in this piece of code, deleted.
If it is the last file, does it delete the whole directory?

 

[Erel]

If it is the last file, does it delete the whole directory?

No.

Add: Log("Globaal.psFileToDeleteUren=" & Globaal.psFileToDeleteUren)
Make sure that it is not empty before the call to Delete.

Thx... the delete action seems to be te problem.
