Android Question Error on Notification

[imak123]

When I run the following code, I got an error : java.lang.IllegalArgumentException: Invalid notification (no valid small icon): Notification(channel=channel_3 pri=0 contentView=null vibrate=default sound=default defaults=0xffffffff flags=0x10 color=0x00000000 vis=PRIVATE). I have place the icon image under \Objects\res\drawable directory.
Would anyone give some advise ?

Thanks

Code :

---

Sub Activity_Pause (UserClosed As Boolean)
n.Initialize()
n.Cancel(1)

End Sub


Sub ReadFromFile
Dim fdName,srcDir As String
srcDir = File.DirAssets
fdName ="introb4a.txt"
If File.Exists(srcDir,fdName) Then
lbDoc.Text = File.GetText(srcDir,fdName)
n.Initialize()
n.Icon ="warning"
n.AutoCancel=True
n.SetInfo("Read file","Completed !","")
n.Notify(1) <--Error occur on this line
Else
ToastMessageShow("Cannot get the File !",False)
End If

End Sub

Sub Activity_Pause (UserClosed As Boolean)
    n.Initialize()
    n.Cancel(1)

End Sub


Sub ReadFromFile
    Dim fdName,srcDir As String
    srcDir = File.DirAssets
    fdName ="introb4a.txt"
    If File.Exists(srcDir,fdName) Then
        lbDoc.Text = File.GetText(srcDir,fdName)
        n.Initialize()
        n.Icon ="warning"
        n.AutoCancel=True
        n.SetInfo("Read file","Completed !","")
        n.Notify(1) <--Error occur on this line
    Else
        ToastMessageShow("Cannot get the File !",False)
    End If

Did you copy your warning icon to the correct place? It needs to be in source folder\Objects\res\drawable

Oh ! My icon is on the wrong folder. Thanks !
