xamarin forms DllImport failing

[mludlum]

I'm having trouble loading the proj v8 library in my Xamarin forms app. Getting DllNotFOundException. I pulled the so files from the 20210911 release.

I have a proj 5.1.0 lib that loads and works. The file format is
libproj.so: ELF 32-bit LSB pie executable, ARM, EABI5 version 1 (SYSV), dynamically linked, with debug_info, not stripped

The format of the files I pulled from this repo's release is:
libproj.so: ELF 32-bit LSB shared object, ARM, EABI5 version 1 (SYSV), dynamically linked, BuildID[xxHash]=65bf5fb7e3983b48, with debug_info, not stripped

Is it related to the file format? If so, is there a way to build the so files to match my working format?
