Google Play Billing v8

Gradle fixes when a non-KTX Billing dependency is present

Only applies to SDK 5.X

This article only applies if you are on SDK 5.X, if you migrated to our SDK 6 you can ignore this article as it integrates this version of Google Play Billing directly

Symptoms

After migrating to Google Play Billing 8.x, some apps may experience that prices are not displayed in Purchasely Screens.

In this situation:

  • the SDK initialization fails to retrieve the Google Subscriptions.y
  • the blocking call is typically queryProductDetails() (Google products fetch)

This prevents all In-App Purchase features from working with Purchasely

Root cause (likely)

This issue can happen when the project includes the dependency:

  • com.android.billingclient:billing (non-KTX)

while the Purchasely SDK relies on:

  • com.android.billingclient:billing-ktx.
⚠️

We suspect an internal behavior change in Google Play Billing v8 non-KTX that can cause a request to hang indefinitely (no success callback, no error callback).

✅ Fix #1 — Use billing-ktx (recommended)

Make sure your app uses the Kotlin variant of Google Play Billing:

dependencies {
    implementation("com.android.billingclient:billing-ktx:8.3.0")
}

✅ Fix #2 — Force Gradle resolution to Billing v8 (workaround)

If another dependency forces billing (non-KTX), you can force dependency resolution to ensure both artifacts are aligned:

configurations.all {
    resolutionStrategy {
        force("com.android.billingclient:billing:8.3.0")
        force("com.android.billingclient:billing-ktx:8.3.0")
    }
}

If the issue persists after applying these fixes, please contact our support team with:

  • Purchasely SDK version
  • Google Play Billing version
  • a list of dependencies bringing Billing into the project (e.g., RevenueCat)
