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 org.pytorch:pytorch_android_lite measured (latest measured 2.1.0); 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 pytorch_android_lite --configuration releaseRuntimeClasspath

Re-verify it yourself

Download the artifact and run the free checker (check16k.py, Python 3, no dependencies):

curl -LO https://repo1.maven.org/maven2/org/pytorch/pytorch_android_lite/2.1.0/pytorch_android_lite-2.1.0.aar
python3 check16k.py pytorch_android_lite-2.1.0.aar

Exit 0 = aligned, 1 = an unaligned library found. Better still, run it on your final .aab/.apk.
