There is a design pattern called MVVM (Model-View-View Model), in which a View Model is used as an abstraction of a View. The View Model supposed to expose streams of data to the View and interact with Model's data.
However there is a ViewModel class in Android's framework.
Question: does Android's ViewModel have something to do with the View Model from MVVM pattern?
They are different. The ViewModel that Android is referring to is just.
The ViewModel class is designed to store and manage UI-related data so that the data survives configuration changes such as screen rotations.
The MVVM pattern will require a View, ViewModel and Model. With binding occurring between the View and ViewModel.
The Android ViewModel interacts with the UIController, and is almost just a state hold for UI, rather than following the MVVM pattern.
