🚨 What Is the 16KB Page Size Requirement?

Google has introduced a requirement that all native libraries (.so files) within your APK or AAB must use 16KB page alignment.
This ensures your app is optimized for the latest Android devices and improves memory efficiency and performance.

If your Flutter app doesn’t meet this standard, it could be rejected during submission or flagged during Play Console checks.

🧠 Why Does It Matter?

Modern Android devices use 16KB page memory systems.
Non-aligned native libraries can cause:

• Increased app load time
• Higher memory usage
• Compatibility issues on newer devices

In short, meeting this requirement is not just compliance — it’s also a performance optimization.

🧰 How to Check if Your Flutter App Meets the 16KB Requirement

Thanks to a verification script shared by developers in the community, you can easily check your APK.

Follow these steps:

1️⃣ Create a new file named check_elf_alignment.sh in your Flutter project’s root directory.
Add the verification script from this link:
👉 Download Script

2️⃣ Make it executable

chmod +x check_elf_alignment.sh 

3️⃣ Build your Flutter APK

flutter build apk --release 

4️⃣ Run the script

./check_elf_alignment.sh app/build/outputs/apk/release/app-release.apk 

This script will verify whether your app’s native libraries are correctly aligned with 16KB page size.

📅 Important Deadline

• Mandatory from: November 1, 2025
• Extension available until: May 31, 2026 (on request)

If your team needs more time to recompile native dependencies or update build pipelines, Google allows a short extension period.
