Android 15: 16 KB Page Size Requirement

Get Ready for Android 15

The 16 KB Page Size Requirement is Here.

Compliance Deadline

May 1, 2026

Apps targeting Android 15+ must support 16 KB memory page sizes. After this date, you won't be able to publish updates on Google Play without this support.

What is a Memory Page?

A memory page is the smallest unit of data for memory management. Android 15 is shifting from the traditional 4 KB page size to a larger 16 KB size to improve performance and system stability, especially on devices with more RAM.

How to Check Your App's Compatibility

Follow this simple process to determine if your app's native libraries (.so files) are ready for Android 15.

1

Locate .so Files

After building a release APK/AAB, extract the `lib` folder to find your native libraries.

⬇️
2

Run PowerShell Script

Use the `llvm-readelf.exe` tool from the Android NDK to inspect each `.so` file's alignment.

Analyze Results

Check the output to see if the alignment is 4 KB or the required 16 KB.

$ndkPath = "C:\Users\username\AppData\Local\Android\Sdk\ndk\29.0.13846066\toolchains\llvm\prebuilt\windows-x86_64\bin\llvm-readelf.exe" # Set the path to your app's native libraries $libsPath = "D:\Android Projects\\app\release\app-release\lib\arm64-v8a" # Iterate through all .so files in the directory Get-ChildItem "$libsPath\*.so" | ForEach-Object { Write-Host "`nChecking $($_.Name) ..." # Run the llvm-readelf command and capture the output $output = & $ndkPath -l $_.FullName # Look for program header alignment lines $aligns = $output | Select-String "0x" if ($aligns) { $aligns | ForEach-Object { if ($_ -match "0x1000") { Write-Host "❌ Found 4 KB alignment (NOT Android 15 ready)" -ForegroundColor Red } elseif ($_ -match "0x4000") { Write-Host "✅ Found 16 KB alignment (Android 15 ready)" -ForegroundColor Green } } } else { Write-Host "⚠️ Could not detect program header alignment" -ForegroundColor Yellow } }

Understanding the Results

The script will clearly indicate the status of each native library.

16 KB Alignment

Your app is Android 15 ready. No action is needed.

4 KB Alignment

Your app is not ready. You need to update your native libraries.

⚠️

Undetected

The alignment could not be determined. Manual inspection may be required.
