Title: Unity Appstore SDK Plugin 64-bit compliance and Amazon IAP support
Hello Amazon Appstore Support Team,
I am publishing a Unity Android app to the Amazon Appstore and I need confirmation regarding Amazon IAP support.
My questions are:
Is the current Appstore IAP SDK Plugin for Unity fully 64-bit compliant for Amazon Appstore APK submission?
Since the Unity IAP plugin is not working properly for Amazon Appstore IAP, what is the recommended solution for Unity developers now?
Is Amazon working on any update or new version of the Amazon IAP / Appstore SDK Plugin for Unity? If yes, please share the expected release date or timeline.
Welcome to the Amazon Developer Community!
Thank you for your questions regarding Unity and Amazon IAP. Here’s what I can share:
1. Is the Appstore SDK Plugin for Unity 64-bit compliant?
No. The current Appstore SDK Plugin for Unity (v3.0.2) is 32-bit only - libAmazonIapV2Bridge.so does not include a 64-bit (ARM64) variant. You will see the “Your APK is not 64-bit compliant” warning when submitting.
2. What is the recommended solution for Unity developers now?
This is a known gap. The options available are:
Option A: Stay on Unity IAP v4.x (com.unity.purchasing v4), which still includes Amazon Appstore support. Note: Unity IAP v5.0+ has removed Amazon support.
Option B: Build a custom Unity-to-Android bridge using AndroidJavaObject/AndroidJavaClass to call the native Android Appstore SDK (v3.0.9) directly. This gives full 64-bit compliance and access to all latest IAP features.
Option C: Submit as 32-bit APK if your target devices support it (note: newer Amazon devices may require 64-bit).
3. Is Amazon working on an update?
There is no publicly announced timeline for a 64-bit update to the Unity plugin. Please watch the Announcements section for updates.
