if you want to target Android devices you may not want to use RMI stuff because Android does not support it as far as I know.

This is NOT Java’s RMI. It is a smaller limited subset built on top of SpiderMonkey. It has none of those compatibility issues.

If the device will run spider monkey then it will run this RMI layer.
