Android Question Boolean will not respond to code in Activity_Create

[Carthalion]

This should be simple, but it is a mystery. I want a login panel to be visible in the Main Activity.

I get no error. I check with a message box. The FolderName is "Demo". This should make LogYn = True. But it is always false. It does not make sense.

Sub Activity_Create(FirstTime As Boolean)
    Activity.LoadLayout("MainMenu")
    Dim FolderName As String
    FolderName = File.ReadString(File.DirRootExternal, "QQFiles/FolderName.txt")
    Dim LogYn As Boolean
    If FolderName = "Demo" Then LogYn= True 'FolderName is "Demo"; LogYn is False
    If LogYn =True Then pnlLogin.Visible= True
End Sub

Make sure that your file does not contain any space or newline (CR and/or LF) character after the "Demo" string
Also make sure that your file is ANSI-encoded. The size of this file should be 4 bytes

I checked. No space, CR etc. The file starts as ANSI-encoded and is uploaded using File.copy. Then it is downloaded using File.ReadString(File.DirRootExternal. The file gets read OK, and it is "Demo" as expected. All this happens for the purpose of storing the file related to the individual user. However, the
IfFolderName = "Demo" does not give a positive response.

Maybe when the file is copied to DirRootExternal and then copied back it loses its ANSI-encoding.

Other than this, I have no idea why it would not work. I appreciate your input.

I check with a message box

This is a mistake. You should use Log instead.

What is the output of:

Log(FolderName)
Log(FolderName.Length)

This is a mistake. You should use Log instead.

What is the output of:

Log(FolderName)
Log(FolderName.Length)

In the Log window after:

Log(FolderName.Length)
    If FolderName = "Demo" Then LogYn= True
    If LogYn =True Then pnlLogin.Visible= True

This does not work:

If FolderName = "Demo"Then LogYn= True'FolderName is "Demo"; LogYn is FalseIf LogYn =TrueThen pnlLogin.Visible= True

Your String contains the " too!
Try this check

If FolderName = $""Demo""$ Then LogYn= True

Yep. Was typing, too

Dim a As String
    a= """Demo"""
    Log (a)
   
    If a="""Demo""" Then Log("True")

Yep. Was typing, too

Dim a As String
    a= """Demo"""
    Log (a)
  
    If a="""Demo""" Then Log("True")

That was it. Quotes around the quotes. I also found that using the Contains property works:

If (FolderName.Contains("Demo")) Then LogYn= True

Thanks!

 

[DonManfred]

Contains property works

contains("Demo") is searching for the String Demo (without quotes)...

If FolderName = $""Demo""$ Then LogYn= True

works
