Publishing from Google Play to the dApp Store

Overview​

Publishing your existing Google Play app to the dApp Store requires:

  1. A release APK file signed with a new, unique signing key (different from Google Play)
  2. Following the standard dApp Store publishing workflow

Key differences from Google Play:

  • File Format: dApp Store submission requires APK files (Google Play uses AAB)
  • Signing Key: Must use a completely separate signing key from Google Play
  • In-App Purchases: No 30% tax on in-app purchases or transactions
Critical Requirement

You cannot use the same signing key for both Google Play and the dApp Store.

Build Your APK​

1. Create New Signing Key​

Generate a new signing key exclusively for the dApp Store:

keytool -genkey -v -keystore dappstore.keystore \
  -alias dappstore \
  -keyalg RSA \
  -keysize 2048 \
  -validity 10000

Store the keystore file and passwords securely - losing them means you cannot update your app.

For reference, view the Android app signing guide.

2. Build Signed APK​

1. Configure dual-store setup in app/build.gradle using product flavors:

android {
    signingConfigs {
        // Existing Google Play signing config
        googlePlay {
            storeFile file("keystores/googleplay.keystore")
            storePassword "your_googleplay_keystore_password"
            keyAlias "googleplay"
            keyPassword "your_googleplay_key_password"
        }
        
        // dApp Store signing config
        dappStore {
            storeFile file("keystores/dappstore.keystore")
            storePassword "your_dappstore_keystore_password"
            keyAlias "dappstore"
            keyPassword "your_dappstore_key_password"
        }
    }

    flavorDimensions = ['store']
    
    productFlavors {
        googlePlay {
            dimension 'store'
        }
        
        dappStore {
            dimension 'store'
        }
    }

    buildTypes { 
        release {
            // Assign signing configs to each flavor
            productFlavors.googlePlay.signingConfig signingConfigs.googlePlay
            productFlavors.dappStore.signingConfig signingConfigs.dappStore
        }
    }
}

2. Build the dApp Store APK:

./gradlew assembleDappStoreRelease

3. Alternatively, build using Android Studio IDE: Build → Select Build Variant → dappStoreRelease → Build APK.

Your dApp Store APK will be at app/build/outputs/apk/dappStore/release/app-dappStore-release.apk

For reference, view the Android signing documentation.

3. Verify APK​

Confirm your APK is properly signed before submission:

apksigner verify --print-certs app-release.apk

For reference, view the apksigner documentation.

Next Steps​

With your signed APK ready, follow the standard dApp Store publishing process:

  1. Set up publishing tools - Install the dApp Store CLI
  2. Prepare your submission - Gather assets and configure app details
  3. Complete publishing guide - Submit your app
