webrtc-sdk android-prefixed 16 KB page-size fix: upgrade to 125.6422.02

Artifact io.github.webrtc-sdk:android-prefixed · measured 2026-10-01 · all libraries

fixed

webrtc-sdk android-prefixed versions up to and including 125.6422.01 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 125.6422.02; the newest measured, 150.7871.01, is aligned.

Caveats

Sampled, not exhaustive: 26 of 28 published versions were measured with native code; unmeasured versions in between are unknown.

	Version	Library file	p_align	File date	Source
Last offending	`125.6422.01`	`jni/arm64-v8a/liblkjingle_peerconnection_so.so`	4 KB (2^12)	Mon, 03 Jun 2024 12:52:35 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("io.github.webrtc-sdk:android-prefixed:125.6422.02")

an aligned version, lowest measured above the last offending one; newer measured versions are aligned too (latest 150.7871.01). Check: ./gradlew :app:dependencyInsight --dependency android-prefixed --configuration releaseRuntimeClasspath

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

./gradlew :app:dependencyInsight --dependency android-prefixed --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/io/github/webrtc-sdk/android-prefixed/125.6422.02/android-prefixed-125.6422.02.aar
python3 check16k.py android-prefixed-125.6422.02.aar

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