Basically in my app am trying to create a sender and a receiver. But am not able to signup the user. keep getting this error have tried online solutions but its not helping.
socket = new Socket("localhost", 3306);//when i change the port number I get an error saying connection refused.
dos = new DataOutputStream(socket.getOutputStream());
source.gdelete();
dos.writeUTF("Signup");//the exception is raised the moment i hit the next line
dos.writeUTF("user");
dos.writeUTF("pass");
dos.writeUTF(port);
