camera-core 16 KB page-size fix: upgrade to 1.4.0
Artifact androidx.camera:camera-core · measured 2026-10-01 · all libraries
fixed
camera-core versions up to and including 1.3.4 that we measured ship 4 KB-aligned native libraries (offending for Google Play's 16 KB page-size requirement). The first measured aligned stable version is 1.4.0; the newest measured, 1.6.2, is aligned.
- The boundary is not exact: only prerelease or unlisted versions lie between the last offending and the first aligned version, so an earlier aligned stable version cannot be ruled out.
- Sampled, not exhaustive: 27 of 113 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 | 1.3.4 | jni/x86_64/libimage_processing_util_jni.so | 4 KB (2^12) | Wed, 12 Jun 2024 17:01:25 GMT | artifact |
| First aligned | 1.4.0 | jni/arm64-v8a/libimage_processing_util_jni.so | 16 KB (2^14) | Wed, 30 Oct 2024 17:02:31 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
implementation("androidx.camera:camera-core:1.4.0")an aligned version, lowest measured above the last offending one; newer measured versions are aligned too (latest 1.6.2). Check: ./gradlew :app:dependencyInsight --dependency camera-core --configuration releaseRuntimeClasspath
Confirm what Gradle actually resolves, since another dependency may pull an older version:
./gradlew :app:dependencyInsight --dependency camera-core --configuration releaseRuntimeClasspathRe-verify it yourself
