🐛 Bug Report: libucs-credential.so and libTransform.so not 16KB Page Aligned on Android #425
Description
Problem Statement
Our Flutter application, which uses the huawei_location plugin, is encountering issues on Android devices with 16KB memory page sizes (especially Android 14/15+ with the Impeller rendering engine enabled). Specifically, the native libraries libucs-credential.so and libTransform.so, bundled within the huawei_location package, are detected as being 4KB page size aligned instead of the required 16KB.
This misalignment can lead to:
App crashes or failures to load the location services on affected devices.
Warnings in the Google Play Console indicating non-compliance with Android 15+ compatibility requirements.
Potential rejection from Google Play for new app submissions or updates targeting Android 15+.
Expected Behavior
The native libraries (libucs-credential.so and libTransform.so) included in the huawei_location Flutter package should be compiled with 16KB ELF segment alignment to ensure full compatibility with modern Android devices and operating system versions (Android 15+).
Steps to Reproduce
Integrate the huawei_location package into a Flutter project.
Build the Flutter application for Android (e.g., flutter build apk --release or flutter build appbundle --release).
Extract the generated APK/AAB file.
Use llvm-objdump (from Android NDK) to inspect the alignment of the shared libraries. For example, on a Linux/macOS terminal:
unzip your_app.apk -d /tmp/my_apk_out
find /tmp/my_apk_out/lib -name "*.so" -exec sh -c 'echo "\n{}"; llvm-objdump -p "{}" | grep "LOAD"' ;
Observe the output for libucs-credential.so and libTransform.so.
Actual Result: The align value for the LOAD segments of libucs-credential.so and libTransform.so shows 212 (4096 bytes) instead of 214 (16384 bytes).
Environment
Flutter Version: 3.24.5
huawei_location Package Version: (latest)
Android Gradle Plugin (AGP) Version: 8.6
Android NDK Version: 28
Target Android API Level (from build.gradle): 35
Device/Emulator where issue is reproduced: (e.g., Pixel 8 Pro with Android 15 Beta, 16KB page size enabled)
Proposed Solution
We request an update to the huawei_location Flutter package. This update should ensure that all included native libraries, especially libucs-credential.so and libTransform.so, are compiled with 16KB ELF segment alignment. This is crucial for app compatibility and performance on newer Android devices and to meet Google Play submission requirements.
