LAN chat of Android WiFi
no vote
In WiFi environment, it can be connected directly. When there is no WiFi environment, LAN can be established by creating hotspots. Because it is a P2P mode, there is no need for an independent server. (of course, it's a pity that we didn't do GPRS / 3G / 4G communication in these network environments), and support sending text, pictures, voice and files (some functions are still under development). For the latest version of open source project, you can pay attention to the project homepage: http://git.oschina.net/hillfly/WifiChat Or https://github.com/hillfly/WifiChat . Source rich public classes and comments. The project is large, and the analysis needs a certain Android foundation.
