Android Question Notification click do event-NB6 Notification

[takhs123]

I try to make a notification which, when user press it, it will open my app and navigate the webview to specific link.
If I put "Main" as fourth element of notification Build it will open my app only,as it should do.
I tried to relpace Main with a function but logger show me problem and it opens me the NB6 library.
How could be done?

Notification Function

Sub Process_Globals
    Dim nf As NB6
End Sub
Sub new_Anouncment_notification(text As String)
    Private smiley As Bitmap
    smiley = LoadBitmapResize(File.DirAssets, "iconb.png", 24dip, 24dip, False)
    nf.Initialize("default", Application.LabelName, "HIGH").AutoCancel(True).SmallIcon(smiley)
    nf.Build("Notification", text, "tag", Navigate_function).Notify(1)
End Sub

You MUST define a ACTIVITY or a Service here. You can NOT define a function here.

Set your activity and call the function in the activity by yourself.
