148: Evolving Android architectures (Part 1)

Jan. 7, 2019

In this episode, Donn and Kaushik talk about the state of android architectures and how they've stared to evolve. Kaushik recently worked on a project of coming up with an evolved version of an MVVM architecture, very similar to what the Android community now calls MVI.

Salient features of the pattern:

I. Screens are driven by a single ViewModel
II. Screens listen to a single Observable exposed from the ViewModel
III. Screens listen to a single Observable exposed from the ViewModel
IV. Events are sent into the VM through a single function processInputs
V. Break(ing) the Chain
VI. Testing strategy

• The state of managing state with RxJava
