Building UI Consistent Android Apps

on YouTube ↗36m

" summary

Yelp creates a shared Android UI library with XML attributes, default styles and Java APIs, publishes it as a Gradle dependency, and wires designer tokens and SVG icons into platform assets. CI (Jenkins) compiles the library against consumer and business apps, runs custom lint checks that ban stock widgets, enforces warnings-as-errors with baseline files, and requires contentDescription and Espresso tests. Automated screenshot capture via espresso screenshot automation generates docs and a style-guide app, and the constrained color palette (only two greens) reduces visual drift.
