构建与Android客户端共享接口的java服务器

2 month ago i started to develop an android application which needs to call remote methods and receive complex objects (custom objects with custom feilds in it) from a server. My friend and I splitted the work so he worked on the android client and i on the server. Before we started, we built the base interfaces which provide the functions that the client needs from the server, so my friend can program easly the application (by using fake classes as implementation for the interfaces), and after i finish the implemntations of the interfaces in the server-side he will make the connection and call the functions from the server and not from the fake classes.2 month ago i started to develop an android app
