A little experience in establishing socket connections in Android

A socket connection is created on the android client and cannot be created through button binding in the oncreate method. Otherwise, use the try {} statement directly in the oncreate method, otherwise, you need to redefine a function outside the oncreate method to create a connection.

You can also use the try {socket = new socket (192.168.1.100, 8001);} statement in the oncreate method to establish a connection. You cannot use the listening event of the binding button to process the connection. Or re-establish a thread for connection. Otherwise, the connection may fail. I personally tried,
