Deploying your Android app
Learn how to prepare and publish your branded Android app on Google Play
This guide outlines the steps you need to follow to properly prepare your Android app for Google review, approval, and successful publication on Google Play.
Step 1. Compliance checkpoint
Before creating and submitting your Android app for Google review, determine the countries where you want your app to be available and ensure you hold all required licenses and legal permissions for each country.
This process may take time, so obtain the necessary licenses in advance to confirm that you are authorized to offer all configured trading instruments in your B2CORE instance and provide this information during the Google Play review.
To learn more about Google Play policies for financial services and cryptocurrency, refer to their Policy center and specifically to the following:
Step 2. Prepare required app information
Prepare the following information that will be required when creating your app in the Google Play Console and submitting it for Google review.
Support and legal information
Provide the following details:
Privacy policy URL — a link to a publicly accessible web page that explains how your app collects, uses, stores, and protects user data.
Demo account — a demo account that Google can use during the review process (for details, refer to Step 3. Create and configure a demo account in the B2CORE UI).
Contact email for Google — an email address used for official communication from Google. This email will be linked to your developer account in Google Play Console.
Public developer contact details — contact information visible to users on Google Play, which must include:
Support email
Contact phone number
Website URL
Store Listing information
Prepare the following store listing details for your app:
App name
Short description (up to 80 characters)
Full description (up to 4,000 characters)
Graphical assets (can be provided by the B2CORE team). To request them, contact [email protected] or your account manager.
Step 3. Create and configure a demo account in the B2CORE UI
To be able to review all of your app functionality, the Google reviewers need access to a demo account. For this reason, you need to configure a demo account as follows:
Verify your demo account by going through all the steps of your configured KYC procedure.
In the Back Office, examine and enable all the B2CORE UI modules that will be featured in your mobile app. Each module must be properly configured to ensure that your mobile app will not be rejected by Google during review.
If your app enables its users to transfer or exchange assets, you also need to make sure that there are enough funds on your demo account, so that the Google reviewers are able to check the transfer and exchange functionality as well.
Step 4. Register in the Google Play Console as an Organization
To publish your Android app, you need to register in the Play Console as an organization and create a developer account.
Further on, with each Android release, the B2CORE team will provide new app bundles (.abb files) for you and you will be responsible for managing the regular maintenance of the app.
For more information, refer to Get started with Play Console.
Step 5. Create a new app in the Play Console
To create an app:
Sign in to the Google Play Console.
Select your developer account.
To start a new app, click Create app.

Ensure that your B2CORE instance supports account deletion. This is a Google Play requirement and may be checked at any time by Google Play or by users. Failure to comply may result in suspension of your developer account in Google Play Console or a permanent ban.

Step 7. Upload the app bundle (.aab) for a production release
To upload your app bundle and configure a production release in the Google Play Console:
In the Play Console, select your app.

Open to the Countries/regions tab and select the countries where you want your app to be available, according to the licenses that allow you to distribute the app and provide services.

Select the option Upload a new app signing key from Java keystore.
Click Download encryption public key (Option 1).
Send the downloaded key in the .pem file format to the B2CORE team either by emailing [email protected] or through your account manager.
The B2CORE team will generate an app signing key, encrypt it using the provided public encryption key, and return it to you together with your application in .aab format, signed with the same key. This process may take some time.
After receiving the signed app bundle (.aab) and the app signing key archive (.zip), return to Test and release > Production > Releases > Untitled release.
On the Releases page, click Edit release.
Upload the received app signing key (.zip).
Select the option Upload the app signing key (.zip).
Click Upload generated ZIP (Option 4).
Upload the received app bundle (.aab).

App review and rollout may take several days. The review will result either in successful publication on Google Play or in a rejection with the reason provided. If you experience issues resolving a rejection, contact the B2CORE team at [email protected].
Step 8. After approval: app monitoring
After your app is approved, regularly check its availability and policy compliance to avoid enforcement actions.
Failure to perform these checks may result in policy violations, app removal, suspension, or permanent termination of your developer account in the Play Console, often without prior notice.
Google Play policies and deployment processes change regularly. If you notice any missing or outdated information in this instruction, contact us at [email protected] for assistance or clarification.
