Optimizing Android Build Speed with Fast‑Build Plugin and Monorepo Strategy at Bilibili

Zhang Yang explains how Bilibili’s massive Android monorepo was accelerated by a fast‑build Gradle plugin that replaces unchanged modules with cached AARs versioned by Git SHA, validates them with an R8‑based A8 check, and leverages cloud compilation and independent build units, cutting full builds from ~30 minutes to under 6 minutes locally and about 3 minutes in the cloud.
