Gplay Screenshot Automation

Google Play Screenshot Management

Use this skill to organize, validate, and upload Android screenshots and store graphics to a Google Play listing with gplay. This skill covers the gplay-specific upload/validate flow — not screenshot capture.

Capturing the raw images is standard Android tooling and not gplay-specific: take them with adb shell screencap (then adb pull), or drive state-based captures with an Espresso / UI Automator instrumentation test, switching emulator locale via setprop persist.sys.locale when you need per-language shots. Produce PNGs organized by locale and device type, then use the commands below.

Directory layout

gplay expects a Fastlane-style tree. sync import-images and release --screenshots-dir both read this shape:

metadata/
  en-US/
    images/
      phoneScreenshots/
        1_home.png
        2_search.png
      tenInchScreenshots/
        1_home.png
      featureGraphic.png
  de-DE/
    images/
      phoneScreenshots/
        1_home.png

Screenshots upload in filename order, so prefix with 1_, 2_, etc. to control ordering on the store.

Image types

Google Play requires PNG or JPEG (PNG recommended), max 8 MB per image.

1) Validate before uploading

Always validate the directory first — this catches count/dimension/format issues before you spend an upload:

# Validate all locales
gplay validate screenshots --dir ./metadata --output table

# Validate a single locale
gplay validate screenshots --dir ./metadata --locale en-US --output table

2) Upload

Option A — bulk import (preferred)

Imports every image in the Fastlane tree in one command. Requires an open edit:

EDIT_ID=$(gplay edits create --package com.example.app | jq -r '.id')

gplay sync import-images \
  --package com.example.app \
  --edit "$EDIT_ID" \
  --dir ./metadata          # add --locale en-US to import one locale, --dry-run to preview

gplay edits validate --package com.example.app --edit "$EDIT_ID"
gplay edits commit   --package com.example.app --edit "$EDIT_ID"

Option B — individual images

Use when you need fine control over specific files:

EDIT_ID=$(gplay edits create --package com.example.app | jq -r '.id')

gplay images upload \
  --package com.example.app \
  --edit "$EDIT_ID" \
  --locale en-US \
  --type phoneScreenshots \
  --file ./metadata/en-US/images/phoneScreenshots/1_home.png

gplay images upload \
  --package com.example.app \
  --edit "$EDIT_ID" \
  --locale en-US \
  --type featureGraphic \
  --file ./metadata/en-US/images/featureGraphic.png

gplay edits validate --package com.example.app --edit "$EDIT_ID"
gplay edits commit   --package com.example.app --edit "$EDIT_ID"

Option C — as part of a release

Upload screenshots alongside a bundle in one release flow:

gplay release \
  --package com.example.app \
  --track production \
  --bundle app-release.aab \
  --screenshots-dir ./metadata \
  --release-notes @release-notes.json

3) Replace existing screenshots

delete-all clears a type for a locale before re-uploading. It defaults --confirm to false and will refuse without it, so --confirm is REQUIRED:

EDIT_ID=$(gplay edits create --package com.example.app | jq -r '.id')

gplay images delete-all \
  --package com.example.app \
  --edit "$EDIT_ID" \
  --locale en-US \
  --type phoneScreenshots \
  --confirm

gplay images upload \
  --package com.example.app \
  --edit "$EDIT_ID" \
  --locale en-US \
  --type phoneScreenshots \
  --file ./metadata/en-US/images/phoneScreenshots/1_home.png

gplay edits validate --package com.example.app --edit "$EDIT_ID"
gplay edits commit   --package com.example.app --edit "$EDIT_ID"

4) Verify what's live

gplay images list \
  --package com.example.app \
  --edit "$EDIT_ID" \
  --locale en-US \
  --type phoneScreenshots \
  --output table

Agent behavior

• Confirm exact flags with --help before running commands.
• Always run gplay validate screenshots before uploading.
• Prefer gplay sync import-images over many individual gplay images upload calls.
• Every write goes through an edit: create → upload/import → validate → commit.
• images delete-all needs --confirm; without it the command refuses.
• Use explicit long flags (--package, --edit, --locale, --type, --file).
• Default to JSON for machine steps, --output table for human review.
