Introducing JRonA

In keeping with the theme of simplicity I have discovered that it's possible to run JRuby on an Android device with a very small amount of Java code. JRonA is all contained in two files with 51 lines of code and JRonA.rb with 24 lines of code. Even I can understand it!

I have called my creation JRonA (short for JRuby on Android) and if you are interested you can download the explanatory JRonA-01.PDF here or the code and examples here.

In a sense this discovery was forced on me because I found it difficult to figure out how to use Ruboto or how it works and JRonA emerged in my struggle to understand.

Have fun!

    Builds and debugs nicely.
