MutableLiveData observes while there is no change in data

Question

I have experienced a weird behavior of MutableLiveData objects as they are sometimes observed continuously even without change in the data in it. As of my knowledge it should be observed only when it comes to active state from inactive state or the data in it has been modified.

In my Viewmodel:

val liveData = MutableLiveData<Any>()

In fragment:

 viewModel.liveData.observe(this, Observer { response -> 
//stuff to do and it is called continuously 
           }
        })

Can you help me understand this behavior or Is there any way to avoid this.

Thanks in advance.

One more question, are you observing it inside `onResume()`? if yes then don't, move it to `onCreate()` of fragment. — Jeel Vankhede, Oct 25 '18 at 11:09

You are observing changes for Any class, try using a different class may be a custom class.

val liveData = MutableLiveData<SomeOtherClass>()

and then observe this like you do.

Yes, i have done this too, this is random. Only some objects are observed, not all. – Vikash Bijarniya Oct 25 '18 at 11:04
