no aligned release found

No measured release of pdfium-android is 16 KB-aligned. The newest measured version, 1.9.2, is still offending.

Caveats

Sampled, not exhaustive: 2 of 2 published versions were measured with native code; unmeasured versions in between are unknown.

Measured evidence

	Version	Library file	p_align	File date	Source
Last offending	`1.9.2`	`jni/arm64-v8a/libc++_shared.so`	4 KB (2^12)	Sun, 22 May 2022 20:18:13 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.github.mhiew:pdfium-android measured (latest measured 1.9.2); 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 pdfium-android --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/com/github/mhiew/pdfium-android/1.9.2/pdfium-android-1.9.2.aar
python3 check16k.py pdfium-android-1.9.2.aar

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