MutableLivedata observer triggering

Question

I have a question about MutableLiveData in Viewmodel. Does just setValue function of MutableLiveData trigger observation? If we change content of MutableLiveData witout setValue, may it be triggered?

Answer 1

I doubt it. Only the mothods below dispatch events to observables:

liveData.postValue("a");
liveData.setValue("b");
