Android Question Problem with File.Exists in debug mode

Andie · May 8, 2017

When running in the debug mode the text file myList.txt is not found and the message box is displayed. In release mode there's no problem. I have no idea, why. Here's the code:

B4X:

        If File.Exists(File.DirAssets, "myList.txt") Then
        Dim tr As TextReader
        tr.Initialize2(File.OpenInput(File.DirAssets, "myList.txt"), "ISO-8859-1")
        datalist = tr.ReadList
        tr.Close
Else
        Msgbox("myList.txt is missing","Attention!")
End If

In most cases it is a mistake to use TextReader or TextWriter. Use File.ReadList instead.

Why do you check whether the file exists? If you added it to the project then it will always be there.

Thanks, Erel. I skipped the File.Exists command - and it works fine.
I used TextReader instead of File.ReadList because of the German "Umlaute". After my opinion I cannot enable ISO-8859-1 in File.ReadList. But may be, I'm wrong ...

You should save the file in your assets using UTF8 Encoding....
If not specified B4A will use UTF8
