I have been testing it , but i did not get the function .
Is there a way
B4X:
Dim rp As RuntimePermissions
Dim n As NB6
Dim folder As String = rp.GetSafeDirDefaultExternal("shared")
Dim FileName As String = "larm.wav"
File.Copy(File.DirAssets, FileName, folder, FileName)
Dim n As NB6
n.Initialize("default", Application.LabelName, "HIGH").SmallIcon(Smiley)
n.SetDefaults(False, True, True)
n.CustomSound(CreateFileProviderUri(folder, FileName))
n.Build(Body, Title, Body, Main).Notify(1)
Yes, it should work. Try to change the channel name. Once a channel has been created it is no longer possible to modify its settings unless you first uninstall the app.
