Hi,

In my company, We use your AdaptiveCards library in our Application.

As per the latest guideline from Google Play Store in https://developer.android.com/guide/practices/page-sizes
Starting November 1st, 2025, all new apps and updates to existing apps submitted to Google Play and targeting Android 15+ devices must support 16 KB page sizes on 64-bit devices.

Could you please share 16KB page size compatible library?

Thanks

Hi!
Unfortunately, there currently is no prebuilt AdaptiveCards Android library on Maven or elsewhere that explicitly declares itself as 16 KB page-size compatible.

Hi 👋

Thanks for raising this — you're absolutely right to be proactive with the upcoming Google Play requirement around 16KB page size support on 64-bit Android devices (starting Nov 1, 2025).

As of now, most open-source libraries — including AdaptiveCards — may not explicitly mention support for the 16KB page size. However, this typically depends more on the native libraries (NDK dependencies) used, as most pure Java/Kotlin code should not be directly affected.

That said, if AdaptiveCards uses native code under the hood or pulls in native dependencies, then yes — ensuring compatibility is important.

✅ What You Can Do:
Check .so libraries: If AdaptiveCards is bundled with native .so files (via JNI/NDK), you'll want to inspect their compatibility. You can use tools like readelf or objdump to inspect alignment and headers.

Raise an issue (if not done already): I’d recommend opening a GitHub Issue directly in the AdaptiveCards Android repo (if this post isn’t already part of it), tagging it under Android and Build.

Fork and patch (as a temporary step): If you or your team has the bandwidth, you could fork the library and recompile it targeting Android 15, ensuring proper alignment and memory configuration via Gradle/Ndk settings.

Follow the Google guide: Refer to Google’s migration docs for tips on ensuring compliance — especially around ld flags and android:extractNativeLibs.

📌 TL;DR:
If AdaptiveCards has native components, it’ll likely need to be recompiled with proper flags for 16KB compatibility. Otherwise, if it’s purely Kotlin/Java, it should be safe — but best to confirm with the maintainers.

Hope this helps while we wait for official confirmation or updates from the library authors! 👍

Hi @SatyamSinghRingcentral,

Thanks for being a part of the GitHub Community, we're glad you're here!

If you're looking for help for this specific topic, you might want to try asking for help somewhere that focuses on this issue. It's possible that another GitHub user might have run into this same issue and can help, but the GitHub Community Discussions focuses primarily on topics related to GitHub itself or collaboration on project development and ideas. We want to make sure you’re getting the best support you can, but this space may not be the right place for this particular topic.

Best of luck!
