The version of Amazon IAP is quite outdated.

[bitdream]

This IAP 2 is marked as decprecated.
Any plan to update it?

and handlePurchase and handlePurchaseError look not called no matter what the results are.

Here in AndoridManifest.xml tools:ignore="ExportedReceiver,InvalidPermission" android:exported="false"
It is very wired since the document said:
If your app targets Android 12 or higher, you must explicitly set android:exported to true in the MainActivity and ResponseReceiver.

Thanks @bitdream ! Just approved the PR. Can you try-out the snapshot and let us know it works for you? Snapshot version will be published into https://oss.sonatype.org/content/repositories/snapshots/

Hi I have tested the current version with AndoridManifest.xml modifications in the pull request from my offline local version.
It worked well in both Amazon Live App Testing and the sandbox app tester with a Kindle Fire HD device.
Not sure how to get and try your snapshot.
