In-app purchase success method not being called after app build

[PopslineContents]

IAP에 연결된 버튼을 누르면 구글에서 제공하는 UI에 제품 상세정보가 나오고, 구매 버튼을 누르면 성공 메시지와 함께 구매 메일이 도착하고, 테스트 빌드라서 취소 메일도 도착한다.

그런데 구매 성공 함수가 호출되지 않고 있습니다.

Logcat으로 확인해보니 아래와 같은 오류 메시지가 나옵니다.

To resolve the issue, I also tried adding the following content to the AndroidManifest.xml:

And I also added the following content to the mainTemplate.gradle to address the version conflict issue with billingclient:
configurations.all { exclude group: ‘com.android.billingclient’, module: ‘billing’ }

My Unity version is 2020.3.48f1, and I’m currently using IAP SDK version 4.11.0.

[unity_1BBB607AB9DB3BBA4465]

Let’s try downgrading the version to 4.10.0

[PopslineContents]

Wow, the problem has been solved.
thank you.

[Yannick_D]

Thank you for the report, I was able to reproduce this and we will fix this in IAP 4.12.0.

If you are using Unity Editor 2020.3, we recommend avoiding IAP 4.11.0 to avoid this issue.
Newer versions of the editor are not affected by this.

[leochien]

We encountered same issue with Unity IAP version 4.12.0, this is NOT fixed in Unity Version: 2020.3.39f1
We had to update to IAP version 4.12.0 due to this issue →

Google Play warning: Ensure that you are not calling setOfferToken

Hi, I just received a very alarming warning on my Google Play developer dashboard: If your app is calling setOfferToken for one-time products and setting it to “”, you will need to update your integration by not setting it to “” by 12 June 2024. We've been using the Unity In App Purchasing library for about 6 months without any issue. Unity In App Purchasing version: 4.11.0 Unity version: 2021.3.37f We have subscription, non-consumable and consumable products. The only thing we hav…

But the new package has another BUG…

[Yannick_D]

Thank you for the reports, we have reproduced this and are working on a fix.
From our findings, this only affects editor versions 2020.3 and earlier, 2021.2 and earlier.

[gab_hw]

Hello Yannick_D, Is this issue resolved for 2020.3 or do you still recommend using the purchasing package 4.10.0?
