I am working on a custom rom for the Unihertz Titan and have come across an issue with the FM Radio application. It requires a library "libfmjni.so" to run. Originally, this shared library is found at /product/lib and /product/lib64.
I exported the APK from my stock rom and even though the library is there, in the place it is supposed to be, i am unable to load it, from anywhere except /system_ext/lib64. When it loads, i am given the message:

I have tried placing the library at /data/,/mnt/expand/, /data/user/0/com.android.fmradio/,/data/user/0/com.android.fmradio/lib//data/user/0/com.android.fmradio/libs/,/data/user/0/com.android.fmradio/lib64/,/data/user/0/com.android.fmradio/arm64-v8a/, /data/user/0/com.android.fmradio/lib/arm64v-8a, /data/user/0/com.android.fmradio/libs/arm64v-8a
Nothing. The only place that reacts to the shared library is /system_ext/lib64 and it cannot load the shared library because it is not in the permitted paths.
I have tried pushing both arm64 and arm versions to these locations.
