   Hi Mr. Davis, do you mind sharing the source code for this app?

   I just got started in Android app development trying to develop an app that will use TCP / UDP as communication method, would like to look at your code for quick start/reference if you don’t mind.
   Millions thanks.

     Hey CK,

     I think the snippet you are interested in is:
     

     
       public void SendPackets(Context context) {
         EditText addressText = (EditText) findViewById(R.id.destination);
         String destination = addressText.getText().toString();
     
         EditText portText = (EditText) findViewById(R.id.port);
         int port = Integer.valueOf(portText.getText().toString());
     
         EditText payloadText = (EditText) findViewById(R.id.payloadcustomtext);
         String payloadTextValue = payloadText.getText().toString();
     
         if (destination.length() < 1) {
           Toast.makeText(context, "Invalid IP", Toast.LENGTH_SHORT).show();
           return;
         }
         InetAddress address;
     
         try {
           address = InetAddress.getByName(destination);
         } catch (UnknownHostException e) {
           Toast.makeText(context, "Unknown Host", Toast.LENGTH_SHORT).show();
           return;
         }
     
         int loopNumber = getNumberFromSpinner();
         for (int i = 0; i < loopNumber; i++) {
           sendPacket(context, destination, port, payloadTextValue);
         }
         Toast.makeText(context, "Packet(s) Successfully Broadcast",
             Toast.LENGTH_LONG).show();
         return;
       }
     
       public void sendPacket(Context context, String ipString, int port,
           String customPayload) {
     
         try {
           int cpl = customPayload.length();
           byte[] bytes = null;
           if (cpl > 0) {
             bytes = customPayload.getBytes("ASCII");
           } else {
             bytes = new byte[6 + 16 * 16 * 16];
             for (int i = 0; i < bytes.length; i++) {
               bytes[i] = 1;
             }
           }
     
           InetAddress address;
           try {
             address = InetAddress.getByName(ipString);
           } catch (Exception e) {
             Toast.makeText(context, "Unknown Host", Toast.LENGTH_SHORT)
                 .show();
             return;
     
           }
           // why is port 7???
           DatagramPacket packet = new DatagramPacket(bytes, bytes.length,
               address, port);
           DatagramSocket socket = new DatagramSocket();
           socket.send(packet);
           socket.close();
     
         } catch (Exception e) {
           return;
         }
     
       }

   Hey I was wondering if you could post the .apk for this app with source… I just got started with creating java apps, and this is something I’ve been wanting to do for a long time.

   There is a way for send, in the same way, a file (instead of writting in the app window) ?
   thanks

     Not currently, but it would be an easy enough change to add to the source code (which is on GitHub). Best of luck!

     Hey Rey,

     All apps I’ve released are open sourced on GitHub.
