Translate example to xamarin and generate the binding library

There is an example application for android (java) that I need to translate to xamarin (c#) , the example is really short so if you know xamarin android you will do it in no time. the example is here [login to view URL] in the repository you will find the source of every pay sdk and also the sample app, so what I need is to generate the bindings for the sdk,(you can compile it from the source or get the jar or aar files from this url [login to view URL]) and then with the bindings generated you need to re create the sample app in a xamarin android app
