How to update LiveData of a ViewModel from background service and Update UI

Question

Recently I am exploring Android Architecture, that has been introduced recently by google. From the Documentation I have found this:

public class MyViewModel         


        

Answer 1

Take a look at the Android architecture guide that accompanies the new architecture modules like LiveData and ViewModel. They discuss this exact issue in depth.

In their examples they don't put it in a service. Take a look at how they solve it using a "repository" module and Retrofit. The addendums at the bottom include more complete examples including communicating network state, reporting errors, etc.
