Do only the work a change requires — recompile what changed, run the tests it can affect, skip the rest
- A one-line change re-runs only the tasks it touched — Build Cache restores the rest, so the build skips compilation and resource work it already did.
- Reuse spans every agent and CI vendor — compile a module once, and every other Android build that needs the same output restores it instead of repeating it.
- Adopt it with no build-script changes — the Android Gradle Plugin is cacheable out of the box, so most Android builds benefit from Build Cache as-is.
- The same avoidance extends to tests — Predictive Test Selection predicts which unit tests a change can affect from build history and runs only those, skipping the rest.
