IVS broadcast 16 KB page-size fix: upgrade to 1.23.0

Artifact com.amazonaws:ivs-broadcast · measured 2026-10-01 · all libraries

fixed

IVS broadcast versions up to and including 1.22.0 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 1.23.0; the newest measured, 1.47.0, is aligned.

Caveats

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: 38 of 129 published versions were measured with native code; unmeasured versions in between are unknown.

	Version	Library file	p_align	File date	Source
Last offending	`1.22.0`	`jni/arm64-v8a/libbroadcastcore.so`	4 KB (2^12)	Wed, 11 Sep 2024 15:15:58 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("com.amazonaws:ivs-broadcast:1.23.0")

an aligned version, lowest measured above the last offending one; newer measured versions are aligned too (latest 1.47.0). Check: ./gradlew :app:dependencyInsight --dependency ivs-broadcast --configuration releaseRuntimeClasspath

Confirm what Gradle actually resolves, since another dependency may pull an older version:

./gradlew :app:dependencyInsight --dependency ivs-broadcast --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/amazonaws/ivs-broadcast/1.23.0/ivs-broadcast-1.23.0.aar
python3 check16k.py ivs-broadcast-1.23.0.aar

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