How to add items to MutableLiveData arraylist?
I have a MainViewModelwith the code:
private val locationList: MutableLiveData = MutableLiveData()
fun getLocationList(): MutableLiveData = locationList

and a fragment where I am trying to add values to the arraylist, but I don't know how:
mainViewModel.getLocationList.value = arrayListof(location) //creates always a new list

Maybe someone can help me.
Thank you
