Gpc Android Cli Interop

GPC Android CLI Interop

What this skill is

A router. Google's official Android CLI covers the build-and-device half of Android app development (scaffold, SDK, emulator, run). GPC covers the Play Store half (preflight, upload, release, vitals, metadata, subscriptions). This skill handles the transition between the two — the moment an AAB or APK is on disk and needs to be shipped.

When to use

Trigger this skill when:

• An agent has just run android run, android build, or equivalent and has an AAB/APK on disk
• The user is coming from a "build worked, now ship it" posture
• A prompt spans both toolchains ("scaffold a Compose app and ship it to internal")
• The user asks "what's the next step" after a successful Google CLI operation

When NOT to use

This skill is a dispatcher, not an implementation. For actual Play Store operations, delegate to the right GPC skill:

| Task | Skill | | --------------------------------------- | ------------------------- | | Upload, release, promote, rollout | gpc-release-flow | | Offline AAB policy scanning | gpc-preflight | | Crash rate, ANR, startup, reviews | gpc-vitals-monitoring | | Store listings, screenshots, metadata | gpc-metadata-sync | | Subscriptions, IAP, pricing, RTDN | gpc-monetization | | Service account, OAuth, ADC, profiles | gpc-setup | | GitHub Actions, GitLab CI, JSON output | gpc-ci-integration | | Managed Google Play private apps | gpc-enterprise | | Fastlane-to-GPC migration | gpc-migrate-fastlane | | Multiple apps / profiles | gpc-multi-app | | GPC-specific errors and exit codes | gpc-troubleshooting |

Handoff procedure

1) Confirm you're at the handoff point

You have an AAB or APK at a known path. Typical locations after android run --release or Gradle:

app/build/outputs/bundle/release/app-release.aab
app/build/outputs/apk/release/app-release.apk

If no bundle exists, the build hasn't completed — loop back to Google's Android CLI skills, not this one.

2) Confirm GPC is configured

Run once per environment:

gpc doctor

Exit code 0 means auth, config, and API reach are all healthy. Non-zero means the user must authenticate first — delegate to gpc-setup.

3) Offline compliance scan

Before any network call:

gpc preflight app-release.aab --fail-on error

9 offline policy scanners (target SDK, permissions, 64-bit libs, secrets, etc.). Catches Play Store rejections before upload. For deeper config, delegate to gpc-preflight.

4) Ship

Hand off to gpc-release-flow for upload, rollout, and promote. Typical one-command release:

gpc publish \
  --package com.example.app \
  --file app-release.aab \
  --track internal \
  --rollout 1.0

gpc publish handles the full edit lifecycle (open → upload → release → commit). For staged production rollouts, promote, or halt, see gpc-release-flow.

5) Verify post-release

After the release is live, check vitals:

gpc vitals crashes --package com.example.app --days 1 --json
gpc vitals anr --package com.example.app --days 1 --json

For thresholds, alerting, and review monitoring, delegate to gpc-vitals-monitoring.

End-to-end example

A user says: "Scaffold a Compose app called Notes, ship a 10% production rollout, and check crash rate after one day."

The full agent path:

# Google's Android CLI (not this skill)
android create --template compose-tutorial --name Notes
android sdk install --platform 34
android run --release

# Handoff (this skill)
gpc doctor
gpc preflight app-release.aab --fail-on error

# GPC release flow (delegate to gpc-release-flow)
gpc publish --package com.example.notes --file app-release.aab --track production --rollout 0.1

# GPC vitals (delegate to gpc-vitals-monitoring, typically after waiting a day)
gpc vitals crashes --package com.example.notes --days 1 --json

Output contract for agents

GPC commands that this skill delegates to all share the same machine-readable contract:

• --json on every command (TTY-aware — structured output when piped)
• Semantic exit codes: 0 success, 1 error, 2 usage, 3 auth, 4 API, 5 network, 6 threshold breach
• --dry-run on every write operation
• gpc changelog generate --format prompt for LLM-ready release-notes prompts (no model bundled — the CLI emits the prompt, the agent runs the inference)

For the full contract, see gpc-sdk-usage and the JSON Output Contract in the docs.
