Twilio Voice 16 KB page-size fix: upgrade to 6.6.3

Artifact com.twilio:voice-android · measured 2026-10-01 · all libraries

fixed

Twilio Voice versions up to and including 6.6.2 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 6.6.3; the newest measured, 6.10.4, is aligned.

Caveats

Sampled, not exhaustive: 38 of 125 published versions were measured with native code; unmeasured versions in between are unknown.

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.twilio:voice-android:6.6.3")

an aligned version, lowest measured above the last offending one; newer measured versions are aligned too (latest 6.10.4). Check: ./gradlew :app:dependencyInsight --dependency voice-android --configuration releaseRuntimeClasspath

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

./gradlew :app:dependencyInsight --dependency voice-android --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/twilio/voice-android/6.6.3/voice-android-6.6.3.aar
python3 check16k.py voice-android-6.6.3.aar

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