SQLCipher (sqlcipher-android) 16 KB page-size fix: upgrade to 4.6.1

Artifact net.zetetic:sqlcipher-android · measured 2026-10-01 · all libraries

fixed

SQLCipher (sqlcipher-android) versions up to and including 4.6.0 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 4.6.1; the newest measured, 4.19.1, is aligned.

Caveats

Sampled, not exhaustive: 24 of 25 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	`4.6.0`	`jni/arm64-v8a/libsqlcipher.so`	4 KB (2^12)	Tue, 21 May 2024 16:18:06 GMT	artifact
First aligned	`4.6.1`	`jni/arm64-v8a/libsqlcipher.so`	16 KB (2^14)	Tue, 20 Aug 2024 14:38:14 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("net.zetetic:sqlcipher-android:4.6.1")

an aligned version, lowest measured above the last offending one; newer measured versions are aligned too (latest 4.19.1). Check: ./gradlew :app:dependencyInsight --dependency sqlcipher-android --configuration releaseRuntimeClasspath

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

./gradlew :app:dependencyInsight --dependency sqlcipher-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/net/zetetic/sqlcipher-android/4.6.1/sqlcipher-android-4.6.1.aar
python3 check16k.py sqlcipher-android-4.6.1.aar

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