UDP-Connections within the emul

Hello Guys,

TCP seems to be a kind of problem !

For now I succeeded, to send data between two UDP-Connections within the emulator. The Log:

Java:

D/UDP(1515): S: Connecting...
D/UDP(1515): S: Receiving...
D/UDP(1515): C: Connecting...
D/UDP(1515): C: Sending: 'Hello from Client'
D/UDP(1515): S: Received: 'Hello from Client'
D/UDP(1515): S: Done.
D/UDP(1515): C: Sent.
D/UDP(1515): C: Done.

I'll have a look for some working TCP-Stuff

The code below will be put into an tutorial right now.

Java:

public class UDPConnection extends Activity {
/** Called when the activity is first created. */
@Override
public void onCreate(Bundle icicle) {
super.onCreate(icicle);
setContentView(R.layout.main);

Thread sThread = new Thread(new Server());
Thread cThread = new Thread(new Client());

sThread.start();
try {
Thread.sleep(500);
} catch (InterruptedException e) { }

cThread.start();
}
}

Java:

public class Server implements Runnable{
public static final String SERVERIP = "127.0.0.1";
public static final int SERVERPORT = 4444;

@Override
public void run() {
try {
Log.d("UDP", "S: Connecting...");
InetAddress serverAddr = InetAddress.getByName(SERVERIP);
DatagramSocket socket = new DatagramSocket(SERVERPORT,serverAddr);
byte[] buf = new byte[17];
DatagramPacket packet = new DatagramPacket(buf, buf.length);
Log.d("UDP", "S: Receiving...");
socket.receive(packet);
Log.d("UDP", "S: Received: '" + new String(packet.getData()) + "'");
Log.d("UDP", "S: Done.");
} catch (Exception e) {
Log.e("UDP", "S: Error", e);
}
}
}

Java:

public class Client implements Runnable {
@Override
public void run() {
try {
Log.d("UDP", "C: Connecting...");
DatagramSocket socket = new DatagramSocket();
byte[] buf = ("Hello from Client").getBytes();
InetAddress serverAddr = InetAddress.getByName(Server.SERVERIP);
DatagramPacket packet = new DatagramPacket(buf, buf.length,serverAddr, Server.SERVERPORT);
Log.d("UDP", "C: Sending: '" + new String(buf) + "'");
socket.send(packet);
Log.d("UDP", "C: Sent.");
Log.d("UDP", "C: Done.");
} catch (Exception e) {
Log.e("UDP", "C: Error", e);
}
}
}
