Android App Submission — Play Console (closed testing)

Submit a native Android app to Google Play for review + closed testing. There is no simple public API for first-time app setup without a Play Developer service account, so this workflow drives the Play Console web UI with Playwright MCP. Everything below was validated end-to-end on a real submission (and a real rejection + fix).

Quick recipe (the must-not-skip path)

1. Build + sign the AAB (§0).
2. Create app → Store listing → all 10 App content declarations → Store settings (§2–§5).
3. Update CHANGELOG.md for this versionName (versionCode) (§0.1) — its top entry is the source of truth for the Play release notes.
4. Closed testing track → Create release → upload AAB → release notes (from CHANGELOG) (§6.1).
5. Testers tab → tick the "All Testers" email list → Save (§6.2). ← never skip; a track with no tester list reaches no one.
6. Countries/regions → add at least one (e.g. Singapore) → Save (§6.3).
7. Submit for Closed testing: Release Review → Save → Go to overview → Submit N changes for review → Send changes for review (§7).
