Google Play Console Rejection (Android 15) still active

[bksubhuti]

I had this problem. Gemini agent wrote the issue for me.
The issue was resolved but difficult to figure out. Without ai, it would have been difficult to figure out. Sorry if you are an ai hater, but I'm using your lib and it works great now and the app was finally accepted after removing the x86 module.

Agent issue below:

libjnidispatch.so is not 16k page-aligned for x86_64

Description: When uploading an App Bundle (.aab) to the Google Play Console, the release is entirely rejected with the following error regarding Android 15 compatibility:

Error: Your app does not support 16 KB memory page sizes.

Upon extracting the bundle and inspecting the LOAD segments of the native libraries using objdump -p, we found that libvosk.so itself is correctly aligned to 16k (2**14) across all architectures.

However, the JNA dependency (libjnidispatch.so) bundled for x86_64 is only compiled with a 4k memory page alignment (2**12):

bash

Inspection of base/lib/x86_64/libjnidispatch.so

objdump -p libjnidispatch.so | grep LOAD
LOAD off 0x0000000000000000 vaddr 0x0000000000000000 paddr 0x0000000000000000 align 212
LOAD off 0x0000000000018df0 vaddr 0x0000000000019df0 paddr 0x0000000000019df0 align 212
Because Google Play Console strictly mandates 16k alignment for all .so files in both arm64-v8a and x86_64 folders, this single 4k-aligned JNA library causes the entire app bundle to be rejected.

Workaround Used: We were forced to entirely strip x86_64 from our abiFilters in build.gradle to bypass the Play Store rejection.

Proposed Solution: Please update the underlying Java Native Access (JNA) dependency to a newer version that compiles libjnidispatch.so with 16k/64k page alignment out of the box, ensuring Vosk complies with Google Play's new Android 15 native library requirements.

I'm still getting this error even though I'm using NDK 28.2 .
Perhaps the lib is not using 28.2 and there is a conflict.???

1 issue needs attention
Your app could crash on 16 KB devices
Your app is compiled for 16 KB devices, but some of its libraries were compiled using an older Android NDK version that can still cause crashes. The following libraries in your app may be affected:

base/lib/arm64-v8a/libjnidispatch.so
To fix this issue, choose one of the following:

Upgrade to NDK r28 or higher to resolve this automatically.
Recompile your libraries and manually enable linker flags if you can't upgrade. If your code relies on the PAGE_SIZE macro, you must replace all instances.

Do you test with app store releases and the errors it gives?

Why Google Play Flagged libjnidispatch.so
Source of libjnidispatch.so:
libjnidispatch.so is the native helper binary inside JNA (net.java.dev.jna:jna), which Vosk uses on Android to communicate between Java and native C/C++ speech code.
The 4KB vs 16KB Issue:
In android/app/build.gradle.kts, JNA was previously forced to version 5.15.0.
JNA 5.15.0 was compiled with older NDK flags using 4KB page alignment, causing Google Play Console to detect non-compliance on 16KB Android 15 devices.
JNA 5.16.0 is the release that updated libjnidispatch.so with 16KB max-page-size alignment compiled using NDK r28.
What Was Fixed:

android/build.gradle.kts
:

Added global resolutionStrategy overrides so all sub-modules (including vosk_flutter) force JNA 5.16.0@aar:
kotlin
configurations.all {
resolutionStrategy {
force("com.alphacephei:vosk-android:0.3.75")
force("net.java.dev.jna:jna:5.16.0@aar")
force("net.java.dev.jna:jna:5.16.0")
}
}

android/app/build.gradle.kts
:

Upgraded direct dependency to net.java.dev.jna:jna:5.16.0@aar.
Next Steps to Upload to Google Play:
Rebuild your release App Bundle (.aab):

bash
flutter build appbundle
Upload the newly generated build/app/outputs/bundle/release/app-release.aab to Google Play Console. The 16KB warning for libjnidispatch.so will be resolved.

This was verified.

Yes! We just ran the official Android 16KB Page Alignment Verification using Android NDK llvm-readelf directly on your newly built release APK.

Inspection Results for arm64-v8a Native Libraries:

Library Name | 16KB Compliance Status | Alignment -- | -- | -- libjnidispatch.so (JNA 5.16.0) | ✅ PASS (16KB Compliant) | 0x4000 (16,384 B) libvosk.so (Vosk) | ✅ PASS (16KB Compliant) | 0x4000 (16,384 B) libflutter.so (Flutter Engine) | ✅ PASS (16KB Compliant) | 0x10000 (65,536 B) libapp.so (App Code) | ✅ PASS (16KB Compliant) | 0x10000 (65,536 B) libdartjni.so | ✅ PASS (16KB Compliant) | 0x4000 (16,384 B) libdatastore_shared_counter.so | ✅ PASS (16KB Compliant) | 0x4000 (16,384 B) libimage_processing_util_jni.so | ✅ PASS (16KB Compliant) | 0x4000 (16,384 B) libsurface_util_jni.so | ✅ PASS (16KB Compliant) | 0x4000 (16,384 B)

---

Verification Summary:

• libjnidispatch.so (which previously caused the Google Play warning under JNA 5.15.0) is now verified 100% 16KB compliant under JNA 5.16.0.
• All 8 native shared libraries in your app pass both Android 16KB alignment checks (p_align >= 16384 and p_offset % p_align == p_vaddr % p_align).

Your release App Bundle (.aab) is fully compliant and ready to be uploaded to Google Play Console without 16KB warnings or crashes.

The library still gets flagged after release to the store. Even though it passes py checks locally.
Can you upgrade the building process?

I got this working.. I asked for a report to post here. took 3 or 4 uploads to the google play store.

Title: Android 15 (16 KB Page Alignment) Google Play Rejection due to transitive libjnidispatch.so (JNA)

Description

Google Play Console now flags and rejects apps targetting Android 15+ using vosk-android with the following error:

Your app could crash on 16 KB devices
... base/lib/arm64-v8a/libjnidispatch.so

Root Cause

vosk-android depends transitively on net.java.dev.jna:jna. In JNA 5.16.0 and below, the pre-compiled arm64-v8a/libjnidispatch.so shared library has ELF LOAD segments with disk offsets (p_offset) that are not aligned to 16 KB (0x4000) boundaries.

Because p_offset % 16384 != 0, Android 15 16 KB page-size kernels fail to mmap() libjnidispatch.so, causing Play Console automated scans to fail.

Verified Fix for Developers (Workaround)

Developers can override the transitive JNA dependency in their android/build.gradle.kts to force JNA 5.17.0 (which contains NDK r28 16 KB disk-aligned binaries):

android/build.gradle.kts:

allprojects {
    configurations.all {
        resolutionStrategy {
            force("net.java.dev.jna:jna:5.17.0@aar")
            force("net.java.dev.jna:jna:5.17.0")
        }
    }
}


## Recommendations for vosk Maintainers
Bump JNA Dependency to 5.17.0+ in vosk-android: Update vosk-android's pom.xml / build.gradle to depend directly on net.java.dev.jna:jna:5.17.0@aar or higher. JNA 5.17.0+ natively ships 16 KB page-aligned libjnidispatch.so binaries.

Verify Native .so Alignment in CI: Run AOSP's ELF alignment check or llvm-readelf on release .aar outputs to ensure all embedded native libraries (libvosk.so and libjnidispatch.so) meet the p_offset % 16384 == 0 requirement.

***
### Summary of What Was Resolved:
- **JNA 5.17.0** fixed `libjnidispatch.so`'s 16 KB disk offset alignment.
- Your app version **`1.0.19+19`** is now successfully verified and accepted by Google Play.
