Bridging amdroid native code

Hi, I’m considering upgrading to enterprise in order to be able to use native android class methods, but I’m not good at java and would like to see what’s involved. I read this in another post:

“You would need to use JNLua to bridge the Java functions contained in the Jar file to Lua. You would essentially be creating a Plugin, that calls the methods from the Jar file and exposes them to Lua.”

I did many searches and keep reading that there is a subfolder after installing enterprise that has a plugin code sample on how to do this bridging of methods from Java and exposing them to Lua. Is there somewhere I could see that sample code perhaps on github or elsewhere so that I can see how involved it is and if it makes sense for me to upgrade to enterprise?

Thanks so much
