Hi! Google required all Android apps to target Android 15 and support 16KB page size. The `libjnind4jcpu.so` and `libnd4jcpu.so` need to be recompiled using r28 NDK. How can I recompile these files from source?

I want to compile them for the 1.0.0-M2.1 version of the library instead of the current main as it’s been tested.

@TinTran64 I’m not going to support the old release for that. An experiment like that would require a commercial support contract. Feel free to file an issue and I can double check it against current snapshots.
