My Android application needs to use an IP address/port to connect to a server. How to know (by code) if the port is already bound or not?

By far the easiest way is to attempt the bind and check the error return (if it succeeded, then it wasn't previously bound).
到目前为止，最简单的方法是尝试绑定并检查错误返回（如果成功，则之前没有绑定）。
