Agora RTC voice-sdk 16 KB page-size fix: upgrade to 4.6.4 (native code removed in 4.5.0)

native code removed

From 4.5.0 on, Agora RTC voice-sdk no longer ships arm64-v8a/x86_64 .so files in this artifact, so upgrading removes the problem here. The natives were removed or moved; see what that means.

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:voice-sdk:4.6.4")

native code removed: 4.5.0 and later (measured latest 4.6.4) contain no arm64-v8a/x86_64 .so; upgrade, then check whether the natives moved to a separate artifact and measure that one // POM META-PACKAGE: voice-sdk 4.6.4 contains no 64-bit .so in the wrapper artifact but declares six native dependencies. Exact 4.6.4 dependency artifacts measured: ains:4.6.4 aligned; audio-beauty:4.6.4 aligned; spatial-audio:4.6.4 aligned; aiaec:4.6.4 aligned; full-voice-drive:4.6.4 aligned; voice-rtc-basic:4.6.4 aligned. This is not proof that another resolved version is aligned; measure the final runtime dependency graph

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

./gradlew :app:dependencyInsight --dependency voice-sdk --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/voice-sdk/4.4.1/voice-sdk-4.4.1.aar
python3 check16k.py voice-sdk-4.4.1.aar

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