Don't be stupid

Generally these projects that combine languages are shit. Jruby is painful, Cython is painful, etc, etc. The documentation is poor, you'll tear your hair out figuring out how to do stuff that's very well documented in the official environment.

And I say this as someone that fucking loves ruby.

It's a bad idea, plain and simple. You'll run into latency and memory issues. Use Java, Kotlin or something like React Naive.

JRuby is fine, though, just not on Android. Aside from taking forever to start up and some incompatibility it's perfectly viable, e.g., for running Rails web applications.

It depends on the task, but Ruby's slowdown from Java is anywhere from 2x slower to over an order of magnitude slower

And keep in mind, these benchmarks are with Hotspot. Android applications are compiled into native code at install time, and may perform slightly faster due to the lack of a JIT performance hit.

It's great for scripting, but don't use it for regular applications.
