Google Play Closed Testing for Kotlin Multiplatform Apps

Kotlin Multiplatform Mobile (KMM) allows developers to share business logic between Android and iOS while keeping platform-specific UI code separate. For Google Play closed testing purposes, your KMM app is treated as a standard Android app. Here is what you need to know.

Building Your KMM App for Google Play

The Android target of your KMM project produces a standard Android application package. Your shared module is compiled into the Android code alongside your platform-specific UI components.

Build your release AAB from the Android module of your KMM project, typically found in the androidApp directory. The process is identical to standard Android: configure your release signing, set your versionCode and versionName, and run the Gradle bundle task.

Google Play Submission

Upload your release AAB to Play Console as you would for any Android app. Configure your closed testing track, set up your tester group, and add your testing service's group email exactly as described in the standard setup guide.

Closed Testing Considerations for KMM

KMM's shared business logic runs identically on Android and iOS, but your Android UI implementation is platform-specific. Use your closed testing period to verify that the Android-specific UI code integrates correctly with your shared module - particularly around state management, navigation, and any platform-specific API calls.

This is genuine testing value that your closed testing period can generate. Document specific KMM-related issues - places where Android behavior differs from your iOS implementation due to platform differences - and address them during the testing period. These become compelling questionnaire answers because they are specific and technically substantive.

Getting 12 Testers

The tester experience is identical to any other Android app. TestSlot testers install your app from the Play Store and interact with it as a regular Android user. The fact that it is built with Kotlin Multiplatform is transparent to them.
