I was trying to establish socket communication between PC(JAVA Server)<-->Android(Client)

on Debugging, popped the problem : Address already in use

instant/feasible resolution i found out was to:

  • run cmd as adminstrator
  • netstat -abn
  • find the process listening to the port of intrest
  • terminate the process from task manager

PS : Unlike from an external application mentioned in previous answers, steps in this answer allows you to find out the used ports with the resources already present.

A few options... us TCPView to find the program that has the port open and kill it... reboot... just reset the network connection. Try those.

If there is really still a process that has the port open, you can easily check for that (and close the process) via TCPView. It might be that the port is just lingering (for example due to not being shutdown properly), in which case you'd have to wait for the socket to close and check that the code is clear with regard to that.
