Do not write the bindings manually. Just use the amazing uniffi-rs library from Mozilla.

https://github.com/mozilla/uniffi-rs

You can generate bindings for multiple languages. It supports error handling on both sides and latest versions also support native async integration.

I've used it to reuse the same Rust engine in iOS and Android apps and write native UI.

Why didn't OP use Panama or the modern Java native APIs which are far better than JNI?

Should be possible with Zig as well. Is this one up to date? https://github.com/zig-java/jui

Proving the point about Android being Google's J++, and Kotlin their C#.

Another useful library in this space that allows you to avoid manually writing bindings is https://github.com/duchess-rs/duchess
