148: Evolving Android architectures (Part 1)

58 minutes

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.
