16 KB page size checker

New Android phones use 16 KB memory pages, and Google Play requires apps that target Android 15+ to support them. Drop your APK or AAB to check every native library the way Google does.

How this check works

It runs the same two checks as Google: the check_elf_alignment.sh script (every LOAD segment of each 64-bit native library must be aligned to 16 KB or more) and zipalign -c -P 16 (native libraries stored uncompressed must start at a 16 KB boundary in the APK).
Only 64-bit libraries (arm64-v8a, x86_64) need 16 KB support. 32-bit ones (armeabi-v7a, x86) never run on 16 KB devices, so they don't count.
Compressed libraries are unpacked when the app installs, so only their ELF alignment matters.
For an AAB, Google Play builds the APKs and handles zip alignment, so only the ELF check applies.
Apps without native code (only Java/Kotlin) already work on 16 KB devices.
