Google Play warning: 16 KB page size not supported in native libraries

[alimcevik]

Description

After integrating the latest Insider SDK, we started receiving a warning from Google Play Console regarding 16 KB memory page size support.

The warning indicates that some native libraries included in the app do not support 16 KB page size.

---

Affected libraries

• libTransform.so
• libucs-credential.so

---

Environment

• Platform: Android (Flutter)
• Target SDK: 35
• Insider SDK version: flutter_insider: ^5.0.1+nh
  

---

Steps to reproduce

1. Add Insider SDK to the project
2. Build AAB (./gradlew bundleRelease)
3. Upload to Google Play Console
4. Observe the warning about 16 KB page size support

---

Expected behavior

All native libraries should support 16 KB page size as required by newer Android versions.

---

Question

Are these libraries compiled with NDK r26+ and do they support 16 KB page size?

If not, is there a timeline for when this support will be available?

---

Additional context

The issue appeared only after adding the Insider SDK, and disappears when it is removed.

Update

We tested different versions of the SDK and found the following:

• The issue does NOT occur with flutter_insider 4.0.6
• The issue occurs with flutter_insider 5.0.1

This suggests that the problem may have been introduced in a later version (regression).

Could you please confirm what changed in terms of native libraries between these versions, especially for:

• libTransform.so
• libucs-credential.so

This information might help identify the root cause.
