It looks like they released the package on June 30, 2025:

• https://mvnrepository.com/artifact/com.android.billingclient/billing/8.0.0

I guess they expect a quick turnaround?

@FANMixco the warning is saying to use 7.x or higher, that is already released?

I just noticed the banner at the top here:

• https://developer.android.com/google/play/billing/query-purchase-history

So, there is no known deadline for 8.x yet. Correct?

I'm already using the V7 and I got the "warning" in my console. So, I'd say there's a deadline.

I'm already using the V7

Ok, what shows the warning? Screenshot?

Are you sure you're using V7, how does Google Play detect it?

And the last one that this old project used was the v7:
https://github.com/jamesmontemagno/InAppBillingPlugin

How does it detect it? I'm not so sure. If it's an error since it's v7, perhaps.

[jonathanpeppers]

Are you able to share your .apk file?

I wonder if there is some Android manifest value, or Android resource it looks for to detect v7.

This package is live:

• https://www.nuget.org/packages/Xamarin.Android.Google.BillingClient/8.0.0

We don't really know if it 100% works, or if there is a new API you'd need that is missing.

Try it out and file an issue if you find any problems, thanks!
