I’m sure not everyone is okey about this chapter…

I have 0 files found in the sounds list…

Regarding the

NotifyPropertyChange(Int)

i kept moving around to check how this can be made…
i found that Android is giving the suggest BR._all… i used it and all is okey

I think this means we can use a single NotifyPropertyChange(Int) function for all the class?

 var sound: Sound? = null
        set(sound){
            field = sound
            //notifyChange() //<-- this or the better below
            notifyPropertyChanged(BR._all)
        }
    
    val title: String?
    @Bindable get() = sound?.name
