用于udp的Android数据报套接字

Question

Should I create each Datagram socket to send upd data every time need send data to server? Or just one Datagram socket for all needed sendind action?

Answer 1

One way to do this is to keep sending your commands from within an eternal loop. Example of this might be the following

while(true) {
   // Create the Datagram   
   DatagramPacket outToServer = new DatagramPacket(data, data.length, serverAddress, port);
   // Create socket to send
   DatagramSocket socket = new DatagramSocket();
   // send datagram through the socket
   socket.send(outToServer);
}

Again, keep in mind that if you want to ensure packet delivery, maybe UDP is not the right way to go
