是否可以创建跨平台的离线移动应用程序？

Question

I mean the simplest possible scenario: one of users starts the app in host mode, and others are in client mode, they can search for nearby hosts (up to 2-3 meters distance) and join selected host and then exchange data with the host. It should work cross platform.

Is this possible at all?

Answer 1

是的，它可能与Visual Studio一起使用XAMARIN（C＃中的代码）

Answer 2

There are already such apps like Firechat , Hood , Jott or YO! (ok, the last one uses Wifi).
