Deploy your app to the Google Play Store

Overview

Use this guide to publish your digital wallet application on Google Play.

Pay special attention to application signing. The signing certificate impacts the application binding key used by NFC Wallet.

If you change the signing key after onboarding, NFC Wallet flows can fail on devices.

Align your Google Play signing setup with the key you registered with Thales.

Prerequisites

Before you start:

• Ensure you have access to Google Play Console.
• Decide whether you publish an Android App Bundle (AAB) or APK.
• Confirm the application binding key you shared with Thales.

  • See Compute the application binding key.

Create the app in Google Play Console

1. Open Google Play Console.
2. Select All apps > Create app.
3. Set the default language.
4. Enter the app name as it should appear on Google Play.
5. Select whether the app is an app or a game.
6. Select whether the app is free or paid.
7. Add a contact email address for end users.
8. Complete the required declarations (for example, content guidelines and export compliance).
9. Select Create app.

Set up store listing and compliance

Use the app dashboard to complete the required sections:

• Store listing details
• App content questionnaires
• App access and privacy declarations
• Target audience and content rating

Google blocks release creation until required items are completed.

Create a release (closed testing)

1. In Google Play Console, select All apps > your app.
2. In the left menu, select Testing > Closed testing.
3. (Optional) Create a new testing track, then select Create new release.

Configure app signing

Choose the option that matches how you want Google Play to sign the version installed by end users.

AAB (recommended by Google)

If you use Google Play App Signing, ensure the app signing key matches the key you registered with Thales.

In App integrity > App signing, select Export and upload a key from Java keystore.

Follow the on-screen instructions to upload your signing key.

APK

Upload artifacts and start rollout

1. Upload your build artifacts:
2. Enter the release name in Release details, then select Save.
3. Select Review release.
4. Review warnings and errors, then select Start rollout.

Your release is now submitted for review.

After Google approves it, you can distribute it to testers (closed testing) or proceed to a production rollout.
