Android Tutorial Android 16KB Page Size Compatibility Checker

This script checks for all the necessary markers to be sure your APK/AAB/SO files are 16KB page size compatible.
It has been simplified to easy usage.

What Does This Check?​

Starting with Android 15, devices may use 16KB memory page sizes instead of the traditional 4KB. Apps with improperly aligned native libraries will fail to load on these devices.

This script performs comprehensive validation that goes beyond simple alignment checks:

• PT_LOAD segment alignment (p_align >= 16384)
• Virtual address alignment (p_vaddr % p_align == 0)
• File offset alignment (p_offset % p_align == 0)
• Congruence requirement (p_vaddr % p_align == p_offset % p_align)
• Android property note detection (.note.gnu.property)

STEPS
1. Make sure to download the NDK tools and extract to a location.Make sure to scroll down to get the latest version, v28 and above

NDK Downloads | Android NDK | Android Developers

developer.android.com

2. Download the SCRIPT: leafy-check-16kb.ps1

3. Open Powershell at the location of the script, run the script,
Interactive Mode (Easiest - script will prompt you for the NDK Path, and then prompt again for the path to APK/AAB/.So etc)
Note: It remembers the NDK Path, so subsequent commands, just hit enter when it prompts for NDK Path

.\leafy-check-16kb.ps1

Command Line ModeYou specify the apk path and ndkpath)

.\leafy-check-16kb.ps1 -Path "C:\path\to\your\app.apk" -NdkPath "C:\Android\Sdk\ndk\27.0.0"

4. If you get Policy Execution error,RUN powershell in Administrator mode and enter this

Set-ExecutionPolicy -ExecutionPolicy RemoteSigned -Scope CurrentUser

Question - your screenshot shows warnings like this

WARNING: No .note.gnu.property section found (may indicate old NDK)

Can we ignore them?

Thank you.

Yes, Ignore - As you can see, I used NDK 29, which is New

 

[Theera]

I wish having B4J Tool. I don't get it.

Check Step #4

Set-ExecutionPolicy -ExecutionPolicy RemoteSigned -Scope CurrentUser

 

[cooperlegend]

yes, tried that, still the same

 

[cooperlegend]

Sussed it, just created my own file and copied the script text to it and run that instead

After updating my .so files, if the operation gives me this result "OK: tutte le .so in arm64-v8a hanno PT_LOAD con Alignment >= 1"(I assume everything is fine)
I upload the app to the store and it accepts it, but why does it keep giving me this warning when checking the store tab under "memory page size"?
Shouldn't the fact that it accepted the bundle be a good sign?
Has anyone else experienced this or figured out how to do it?
Thanks a lot.
