Measured evidence
| Version | Library file | p_align | File date | Source | |
|---|---|---|---|---|---|
| Last offending | 4.5.3.0 | jni/arm64-v8a/libc++_shared.so | 4 KB (2^12) | Tue, 07 Sep 2021 07:45:50 GMT | artifact |
p_align is the smallest PT_LOAD segment alignment of the ELF. 16 KB-compatible needs at least 16384 (2^14). Method: min PT_LOAD p_align of arm64-v8a/x86_64 .so inside the published AAR/JAR; aligned = >=16384 for every lib. Dates are repository file times, not official release dates.

The Gradle change
no 16 KB-aligned release of com.quickbirdstudios:opencv measured (latest measured 4.5.3.0); ask the vendor, check for a fork, or re-link the .so yourself; replacing is the last resort
Confirm what Gradle actually resolves, since another dependency may pull an older version:
./gradlew :app:dependencyInsight --dependency opencv --configuration releaseRuntimeClasspathRe-verify it yourself
Download the artifact and run the free checker (check16k.py, Python 3, no dependencies):
curl -LO https://repo1.maven.org/maven2/com/quickbirdstudios/opencv/4.5.3.0/opencv-4.5.3.0.aar
python3 check16k.py opencv-4.5.3.0.aarExit 0 = aligned, 1 = an unaligned library found. Better still, run it on your final .aab/.apk.
