    <p>I was wondering how can I break a message into multiple messages of 15 characters and send it over udp connection. and how can I make the first message to be sent is the number of packets(messages to be sent) right now I can only send one packet</p> <pre><code>public class MainTalker extends Activity { private static DatagramSocket socket; private static DatagramPacket packet; private static Thread send; private Button cl1; private static EditText ed1; private static String msg = "Message"; private static byte[] data = new byte[15]; private static String TAG = "Sender UDP"; static int count=0; static String[] output = new String[100] ; @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_main_talker); ed1 = (EditText) findViewById(R.id.msg); cl1 = (Button) findViewById(R.id.send); try { socket = new DatagramSocket(11001); Toast toast = Toast.makeText(getApplicationContext(),"Port Opened",Toast.LENGTH_SHORT); toast.show(); System.out.println("Port Opened "); socket.setBroadcast(true); } catch (Exception e) { System.out.println("Exception: Port not opened"); e.printStackTrace(); Log.e(TAG, e.getMessage()); } cl1.setOnClickListener(new View.OnClickListener() { public void onClick(View v) { System.out.println("Button Clicked "); send = new sendthr(); send.start(); } }); } private static class sendthr extends Thread { public void run() { System.out.println("Thread Started"); String messg = ed1.getText().toString(); for(int i=0; i&lt;messg.length(); i+=10) { output[i] = messg.substring(i,i+10); System.out.println(output[i]); count++; if (messg == null) output[i] = msg; data = output[i].getBytes(); try { //Create packet with target host and target port packet = new DatagramPacket(data,data.length,InetAddress.getByName("192.168.8.17"), 11001); System.out.println("Packet Created"); } catch (UnknownHostException e) { System.out.println("Exception: Packet Created"); e.printStackTrace(); Log.e(TAG, e.getMessage()); } try { System.out.println("Sending the packet "+ msg); socket.send(packet); System.out.println("Packet sent"); } catch (IOException e) { System.out.println("Exception: Packet Send"); e.printStackTrace(); Log.e(TAG, e.getMessage()); } } } } } </code></pre>

    1. COYou'd use a loop to process the string in question 15 characters at a time. Here first you need to learn a little bit of Java. http://javala.cs.tut.fi Then once you've figured that part out, you'll have to execute this on its own thread, but a better question should be why are you trying to do this in the first place? Most likely, I'm willing to bet there is a better library function for what you're trying to do. It's just I can't quite figure out what your end goal yet.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
