Publish Your Rey App to Google Play

Submit your Rey app to Google Play so real users can discover and download it on Android — no Android Studio or coding required.

Publishing to Google Play puts your app in front of billions of Android users worldwide. Rey handles the Android build, signing, and submission — you focus on filling out the Configure Android deployment dialog.

Before you start

You’ll need each of these set up on Google’s side before Rey can build and submit your app.

Google Play Developer account

Enroll in the Google Play Console (one-time $25 USD fee).

Package name

Choose a unique application ID for your app.

App record in the Play Console

Create the Play Store listing your builds will be uploaded to.

Google service account key

A JSON key so Rey can publish on your behalf.

Configure Android deployment

Open your app in Rey, click Publish in the top toolbar, and choose Android. The Configure Android deployment dialog has three tabs — App, Credentials, and Assets. You can save partially and come back later.

App

Field	What to enter
App name	The name people see under the app icon on their home screen. Keep it short so it fits — it doesn’t have to match your Play Store listing name.
Package / bundle ID	The package name you registered earlier (e.g. com.yourcompany.yourapp). Find it in the Play Console under All apps → (your app) → Dashboard, or in App integrity.

See Register a Package Name if you haven’t chosen one yet.

Credentials

Paste the Google Play service account JSON so Rey can upload builds on your behalf. Download it from the Play Console API access page — full walkthrough at Google Service Account Key.

By default Rey manages your Android keystore and upload key for you. You only need to reveal the keystore configuration if you’re migrating an existing app with an existing signing key.

Assets

Asset	Requirement
Icon	1024×1024 PNG. Used as the app icon and, if no splash image is provided, as the splash screen.
Splash Image	2732×2732 PNG. Shown on launch on both iOS and Android. Falls back to the icon if not uploaded.
Background Color	Hex color used behind the icon and splash on both platforms.

Assets are shared between iOS and Android — if you already uploaded them when configuring iOS deployment, they’ll appear here too.

Submit your app

1. Fill out all three tabs

   Complete App, Credentials, and Assets in the Configure Android deployment dialog, then click Save.

2. Click Publish to Google Play

   Rey builds your Android app, signs it, and uploads it to the Play Console.

3. Finish the listing in the Play Console

   Log in to the Play Console to add screenshots, feature graphic, description, category, and content rating, then submit for review.

4. Monitor your review status

   Initial Play Store reviews typically complete within a few hours to 3 business days.

Make sure your app complies with Google Play’s Developer Program Policies before submitting. Common rejection reasons include missing privacy policy, undisclosed permissions, and broken functionality.

Publishing app updates

When you’re ready to release a new version, make your changes in the Rey editor and click Publish again. Rey increments the version code, rebuilds, and resubmits to the Play Console. You don’t need to touch Android Studio or any build tooling.

Plan requirements

Publishing to Google Play is included on all paid plans — Starter, Grow, and Scale.
