Doply Service Usage Guide

Last Updated: 2026.08.21

Prerequisites

Check the items you need to prepare before using the service

Activate Internal Testing Track and Publish Internal Test App

The internal testing track must be activated in Play Store Console and the internal test app must be published.

Check App Release Version (Target SDK, Min SDK)

Doply's test devices have Android 13 and 14 installed. To install the app on test devices, please set minSdk to Android 13 (API 33) or below. Set targetSdk to 36 or 37.

You can configure this in one of the following files:

• build.gradle (Module: app) - defaultConfig { minSdk 33; targetSdk 36 }
• AndroidManifest.xml - <uses-sdk android:minSdkVersion="33" android:targetSdkVersion="36" />

Check Release Countries

Test accounts are Korean nationals. Please include "South Korea (Republic of Korea)" in the release countries for app installation.
This applies to the closed testing track only — you can exclude South Korea from your production track.

Verify Internal Testers Addition

After adding Doply internal testers, please confirm that the app review has been completed. "Under review" should not be visible on the Play Console dashboard.

Step 1: Register Testers

1. Download Tester List CSV

Download the CSV from the "Tester List Page".

2. Access Google Play Console

3. Enter Tester Management Menu

4. Upload Tester List CSV

5. Confirm CSV File Upload

6. Send Tester Invitation Email

7. Confirm Tester Approval

8. Confirm Closed Testing Release

9. Complete Tester Registration

Step 2: App Registration

In Doply's "Closed Testing" menu, click the "Register App" button to register the app for closed testing.

Note: The app must be properly published on the internal testing track and in a published state. (If "Under review" is displayed, you must wait until publishing is completed.)

Step 3: Service Compatibility Check

Analyze app requirements to automatically determine if Doply service is available.

Automatic Compatibility Check Items

✓ Supported Countries

Korea must be included

✓ Android Version

Minimum SDK 33 (Android 13) or below, Target SDK 36 or 37

✓ App Type

Free/Paid app classification (paid apps must be made temporarily free)

Service Unavailable Conditions

Service may be difficult to use if the following conditions apply:

• Release countries do not include Korea
• Android minimum supported version is API 34 (Android 14) or higher
• Paid app (set a 100% discount in Play Console to make the app temporarily free during the test period. Google guide)
• Adult verification required during installation

Solution: Try adjusting the app's target countries or minimum requirements in Play Console and try again.

Service Available

When the number of installable devices is determined to be 14 or more, the status changes to service available.

Currently Paid Service: For installation requests, please contact us through "Contact Us".

Step 4: Installation and Testing Start

Install approved apps on actual devices to start testing. This process is automated.

1. Click Installation Request Button

Click the "Installation Request" button on the app details page to start automatic installation.

2. Sequential Installation on Each Device

The system automatically installs the app on registered tester devices. Progress can be checked in real time.

3. Testing Status Activation (When 12+ Devices Installed)

When the number of installations reaches 12 or more, the app status changes to "Testing" and the full testing period begins.

Installation Retention Period: Maintained for 18 days

The app is maintained for 18 days to prevent automatic deletion from devices.

Minimum Installation Count: 12+ devices

According to Google Play policy, a minimum of 12 devices must be installed.

Note: During installation, some devices may fail to install due to compatibility issues. This is normal, and testing can proceed once 12 or more devices are installed.

Step 5: Closed Testing Period (14 days)

Duration: 14 days

This is the most important step. During 14 days, increase Google Play approval possibility through active updates and tester activities.

Key Point: You may be rejected for lack of updates, so perform at least 2 updates, recommended 3-4 updates.

1. Release New Version in Google Play Console

Upload and release a new version of your app to Google Play Console every 3-4 days.

2. Check Automatic Update Progress

The Doply system automatically checks and proceeds with updates, and you can check the progress on the installation history page.

Update Frequency: 3-4 day intervals

Maintain appropriate intervals, not too fast or too slow.

Step 6: Production Application

After completing the 14-day test, apply for production release in Google Play Console. Proceed carefully to increase success rate.

1. Confirm 14-day Testing Period Completion

Production application is possible only after exactly 14 days from the start date of closed testing.

2. Apply for Production in Google Play Console

Google Play Console → Dashboard → Click Production Application button

3. Complete App Content Survey

Complete the Google Play policy survey. Refer to the recommended answers provided by Doply. You can check service-customized recommended answers through the "Production Survey" menu on the app details page.
