Engineering for Sustainability: Building a Carbon-Aware App with Android
summary
Claims concrete numbers and tools: cites studies that ~45% of uninstalls tie to battery drain, warns EU Green Claims Directive enforcement from March 2026, and measures energy in joules/mW via Android 16 Power Profiler, automated Macrobenchmark v3 runs on Firebase Test Lab producing JSON, and live headroom from SystemHealthManager (0–800 scale, sweet spot >70, danger <20). Describes a CI “green gate” that rejects >5% energy regressions, a WorkManager carbon‑aware deferral using ElectricityMaps, and a failed ARR demo that didn’t run.
