It is going to be hard to reduce the size of our .so as we are already agressive with the compiler options. Maybe ABI split can help you: https://realm.io/docs/java/latest/#faq-library-size

Well I am looking about abi split, and react-native has sensible defaults regarding it, What I was wondering was wanting to only opt into realm object server and strip out unnecessary size for unwanted features if possible?

I am afraid that it is not possible to cherry-pick components. We hope to upgrade Android NDK soon, and maybe clang will be able to reduce the size a bit.

Ok I'll try again with newer/upcoming versions and open again if necessary.
