Presentation Model may not be saved?

If onSaveInstanceState() called before remote api callback, Presentation Model may not be saved?

it might depend on exact Android implementation, but if your model is stored as Parcelable there is a good chance system will not persist it until it really needs, even though it called onSaveInstanceState. It might just hold the reference until it is really needed and the memory is low. But I would not make any assumptions on that and would suggest to either cancel api call in detachView or onDestroy, or check whether the model contains the data that came from API callback on each attachView. (Assuming you saved this data into the model after in the callback)
