Resolved Google Play Billing Library v4

This app was found to be using an outdated version of Google Play Billing. Beginning November 1, 2022, all app updates must use Billing Library 4 or later.

I am using Google Play Billing Library v3. How do i update i couldn't find.

 

Unity IAP 4.4.1 is now available. Install via the Package Manager.

Please note that for Unity 2021+, until this package is considered "verified" for your version of the Unity Editor, you may need to specify the version manually to install it explicitly. Unity 2021 Package Manager > "+" > Add package by name ... > com.unity.purchasing > 4.4.0. Also note that this is a fully supported package, regardless of our "verified" flag.

See documentation: https://docs.unity3d.com/Packages/com.unity.purchasing@4.4/manual/index.html

Changes: https://docs.unity3d.com/Packages/com.unity.purchasing@4.4/changelog/CHANGELOG.html


[4.4.1] - 2022-08-11
Fixed

• GooglePlay - Fixed NullReferenceException and ArgumentException that would rarely occur due to a concurrency issue introduced in Unity IAP 4.2.0
• Amazon - Set android:export to true to support Android API level 31+

 

You need Unity IAP 4.4.0 or above for Google Play Billing Library v4

 

My project is using Unity 2019.4.30f1 and, as far as I see in the update package manager UI, I can upgrade till IAP 4.1.5.
Is version 4.4.0 planned on Unity 2019 or I have to upgrade to Unity 2020?

Thanks.

Hi @Tx,

Unfortunately Unity is no longer supporting 2019.4, and therefore we no longer have QA support for packages on that editor.

We've also added some C# code that the 2019.4 compiler didn't support by default and are continuing to do so.

Sorry for your inconvenience.

 

Dear @Tx,
i did custom a library to use billing-4.0.0 to use in unity 2019 or lower. Because cost for upgrade my project to new unity version is expensive.
Hope help someone.
