Agora special full 16 KB page-size fix: upgrade to 4.3.2.8

Artifact io.agora.rtc:agora-special-full · measured 2026-10-01 · all libraries

fixed

Agora special full versions up to and including 4.3.2.7.LITE 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 4.3.2.8; the newest measured, 4.6.3.138, is aligned.

Per-major-line fixes

Different major versions have separate fix paths:

4.x: upgrade to 4.3.2.8

Caveats

Non-monotone history. An aligned stable release exists before a later offending one (parallel release lines or backports). A higher version number does not guarantee alignment: pick your exact version and measure it. The version below is only the lowest aligned stable version above the highest offending one.
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.
NON-MONOTONE: an aligned release can be followed by an offending one; do not assume newer is safe. Per-release-line guidance: 2.x -> no aligned release measured after offending 2.9.107.212; 3.x -> no aligned release measured after offending 3.7.203.212; 3.7.3.175 was aligned before the regression; 4.x -> use measured aligned 4.3.2.8 (after offending 4.3.2.7.LITE). Re-run the checker on the version you resolve
Sampled, not exhaustive: 61 of 1457 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	`4.3.2.7.LITE`	`jni/arm64-v8a/libagora-ffmpeg.so`	4 KB (2^12)	Tue, 15 Oct 2024 06:45:50 GMT	artifact
First aligned	`4.3.2.8`	`jni/arm64-v8a/libagora-fdkaac.so`	16 KB (2^14)	Thu, 31 Oct 2024 07:13:01 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.agora.rtc:agora-special-full:4.3.2.8")

an aligned version, lowest measured above the last offending one; newer measured versions are aligned too (latest 4.6.3.138). Check: ./gradlew :app:dependencyInsight --dependency agora-special-full --configuration releaseRuntimeClasspath // NON-MONOTONE: an aligned release can be followed by an offending one; do not assume newer is safe. Per-release-line guidance: 2.x -> no aligned release measured after offending 2.9.107.212; 3.x -> no aligned release measured after offending 3.7.203.212; 3.7.3.175 was aligned before the regression; 4.x -> use measured aligned 4.3.2.8 (after offending 4.3.2.7.LITE). Re-run the checker on the version you resolve

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

./gradlew :app:dependencyInsight --dependency agora-special-full --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/agora/rtc/agora-special-full/4.3.2.8/agora-special-full-4.3.2.8.aar
python3 check16k.py agora-special-full-4.3.2.8.aar

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