64bits libOni.so reports UnsatisfiedLinkError exception

Hi there,

Will investigate this and report back asap. In the meantime, using the Burst backend will circumvent any issues you may have with the native library (as libOni.so is no longer needed), and will likely result in slightly better performance on mobile platforms.

I've been so far unable to reproduce this issue in any Unity version (2018.X, 2019.X and 2020.X) so it's quite unlikely for the NDK version to be the culprit, though.

thanks for the reply, I finally found out the cause, there's another libc++_shared.so under the library loading path which will be loaded before the one we have in the Obi plugin, however, the loaded libc++_shared.so doesn't contain the symbol "_Unwind_Resume", which cause the libOni.so complaining the absence of the symbol
