[@hmscore/react-native-hms-iap] Sandbox testing doesn't work

[yaroslavnikiforov]

Description I added my Huawei ID to the test accounts in AppGallery Connect according to the instruction but I don't get any dialogs that it is a test: https://developer.huawei.com/consumer/en/doc/distribution/app/agc-help-testaccount-0000001146438651 https://developer.huawei.com/consumer/en/doc/development/HMSCore-Guides/sandbox-testing-0000001050035039

Expected behavior Should see messages about sandbox testing on the checkout screen.

Current behavior Don't have any test messages on the checkout screen.

Also payOrderId property in InAppPurchaseData returned by obtainOwnedPurchases method is equal to "SandBox_1650649777607.4CF742B3.0023", but in HMS Core app I have a real subscription

The solution is in this message from HMSIapModule.isSandboxActivated() response: "errMsg": "The versionInApk should be more advanced than versionFrMarket"

So versionCode in defaultConfig under android/app/build.gradle should be higher than the latest released app version in AppGallery.
