Since JavaMoney/javamoney-lib#15 has been closed, I'm opening this issue here.
It would be nice to see the JavaMoney Reference Implementation running on Android so that Bitcoin (and Bitcoin 2.0) Android wallets could use JavaMoney components. It might be possible using RetroLambda and/or other tools. Note that there is an (empty) repository, https://github.com/JavaMoney/javamoney-api-bp, for an API back port.
