In this gripping episode, Tor Norbye and Chet Haase are joined by the pixel-pushing Kirill Grouchnikov from the Play Store team. Kirill works on UIs for this large data-driven app that runs on a wide variety of releases, devices, and form factors. We talk about what that actually entails... and talk about other stuff along the way.
