I've been learning solidity & viper for some time now but i am wondering if it's possible to call the functions/methods of a smart contract (already deployed on Ethereum Network) from an Android/iOS application. If it is, then how do we go about doing it?
I found this project on GitHub, which is creating APIs for the Smart Contract. Once the code is deployed on the server those APIs can be called from Android/iOS. But, in the project we are using TestRPC for deploying the Smart Contract. So, what i don't understand is how can it communicating with the Smart Contract which is already deployed on the Ethereum Network?
