This is how I have set up my DAO

@Query("SELECT * FROM alarm_table order by id")
List<AlarmEntity> getAllAlarms();

and I have the following in my viewmodel class

private MutableLiveData<List<AlarmEntity>> allAlarms;
public AlarmViewModel(@NonNull Application application) {
    super(application);
    dataBAse = RoomDB.getInstance(application.getApplicationContext());
    allAlarms = new MutableLiveData<>();
    loadAlarms();
}

//getting all alarms from database
private void loadAlarms() {
    AppExecutors.getInstance().diskIO().execute(new Runnable() {
        @Override
        public void run() {
            List<AlarmEntity> alarmItems =  dataBAse.alarmDao().getAllAlarms();
            allAlarms.postValue(alarmItems);
            Log.d(TAG, "run: "+alarmItems);
        }
    });
}
//passing the data to main Fragment for displaying
public LiveData<List<AlarmEntity>> getAllAlarms() {
    return allAlarms;
}

and this is my observer in fragment

viewModel.getAllAlarms().observe(getViewLifecycleOwner(), new Observer<List<AlarmEntity>>() {
    @Override
    public void onChanged(List<AlarmEntity> alarmEntities) {
        alarmEntityList.addAll(alarmEntities);
    }
});

I’m a bit confused since my LiveData oes not automatically update when I add a new record to my Room Database,

Im expecting auto updates on it’s own without me having to call the getAll() method everytime I add a new Item. When you have LiveData, does the Android OS shoul should auto update this List when you add/delete/update a record in the Database? Thanks.
