Hi all
I want to communicate two emulators via DatagramSocket in Android. Each of them is a Node in a P2P system. Thus each of them has a server Thread and client Thread (created per GUI event). This is how I create server
public static final String SERVERIP = "10.0.2.15";
//...
run() {
InetAddress serverAddr = InetAddress.getByName(SERVERIP);
DatagramSocket socket = new DatagramSocket(SERVERPORT,serverAddr);
while(true) {
byte[] buf = new byte[29];
DatagramPacket packet = new DatagramPacket(buf, buf.length);
socket.receive(packet);
//...
}
}
The port is given by the user during initializing application.
The client part (requesting some data)
InetAddress serverAddr = InetAddress.getByName("10.0.2.2");
//...
Log.i("Requester", "Trying to connect to device port = "+target);
DatagramSocket socketJ = new DatagramSocket();
byte[] bufJ = Adaptor.createStringMsg(Adaptor.createJoingMsg(id, Location.getX(), Location.getY())).getBytes();
DatagramPacket packetJ = new DatagramPacket(bufJ, bufJ.length, serverAddr, target);
Log.i("Requester", "Sending: '" + new String(bufJ) + "'");
socketJ.send(packetJ);
Log.i("Requester", "Done.");
Some additional info. The Node1 (emulatorA) has a server on port 8000 and Node2 (emulatorB) has a server on port 8001. The target port for "client part" is read properly. What tried to do is to set the redirection as such:
//emulatorA
redir add tcp:8000:8000
//emulatorB
redir add tcp:8001:8001
However I can not get any communication beetwen those 2 emulators. As far as I understood the android tutorial about it should work like this redir add tcp:localhostPort:emulatorPort. I'm stuck with it :/. Can anyone point me the mistake or give some good advice. For the record while I was testing communication on a single device (client faking other node) everything worked, so I don't think there is a bug in the code.
Btw does any one knows how can I get 2 set of logs for those 2 emulators (logA, logB)? It would help me a lot.
