Why don't armeabi-v7a and x86 support the 16KB page size?

Hi,

implementation 'com.google.mlkit:segmentation-selfie:16.0.0-beta6'

As you can see, I ran a small test to check whether all .so files in my app support the 16KB page size. Here's what I got:

Checking folder: 
F:\Sdk\ndk\27.0.12077973\toolchains\llvm\prebuilt\windows-x86_64\bin\jni\arm64-v8a\libxeno_native.so => Align: 0x4000
✅ 16KB page size supported

Checking folder: 
F:\Sdk\ndk\27.0.12077973\toolchains\llvm\prebuilt\windows-x86_64\bin\jni\armeabi-v7a\libxeno_native.so => Align: 0x1000
⌠Only 4KB page size

⌠Only 4KB page size

Why don't armeabi-v7a and x86 support the 16KB page size?

I am also facing this same issue \e[31mFound 2 unaligned libs (only arm64-v8a/x86_64 libs need to be aligned).\e[0m I am using implementation "com.google.mlkit:barcode-scanning:17.3.0" could you please fix this issue

The hint is in the comment (i.e., only arm64-v8a/x86_64 libs need to be aligned) - if you are doing this to meet Google's impending Play Store Requirement, you do not need to worry about these architectures :

In fact, there is no practical benefit to supporting 16kb page sizes on these legacy architectures because Android doesn't support 16kb page sizes on anything other than arm64 processors (even the x86_64 Cuttlefish support is emulated).

Thanks for the help. Closing this issue.
