Jetpack Benchmarks and Where to Find Them
summary
Concrete setup and results: the Jetpack Benchmark Library is added as a benchmark module or main-module workaround with the gradle plugin and output JSON enabled, tests run on device not emulator using measureRepeated, and CI invokes device runs via Firebase Test Lab from a GitHub Actions workflow. The pipeline copies benchmark-result.json, compares total runtime (nanoseconds) between runs, opens a PR with a comment, and flags regressions; engineers report ~25–30% cold-start gains and scroll measurements ranging from ~15s minimum to ~97s maximum.
