I've been scouring the forums and found similar issues like this, but
the solutions seems not to be working.
What we're doing is trying to receive data from an external server via
UDP. At the moment, doing a tcpdump on linux provides information that
yes, there is data coming into my computer. From here, however, things
become murky.
I have tried the following two tactics:
telnet localhost 5554
>> redir add udp:5000:5000
where 5000 is the port on my computer that is receiving data and 5000
is the port where Android is listening to. This achieves nothing.
The other tactic is the adb forward, which has the same results.
The UDP Server code is as follows:
public class Server extends Thread {
private InetAddress serverAddr;
private DatagramSocket socket;
private static int port = 5000;
private static final String tag = "UDP Server";
public Server() {
try {
this.serverAddr = InetAddress.getByName("10.0.2.15");
this.socket = new DatagramSocket(port, this.serverAddr);
Log.d(tag, "listening port 5000");
} catch (Exception e) {
Log.d(tag, "Failed accessing server address and
socket");
}
}
public void start() {
super.start();
}
public void run() {
Looper.prepare();
while(true) {
try {
byte[] buf = new byte[43];
/* Prepare a UDP-Packet that can
* contain the data we want to receive */
DatagramPacket packet = new DatagramPacket(buf,
buf.length);
this.socket.receive(packet); // Receive the
UDP-Packet
Log.d(tag, "Received: '" + new
String(packet.getData()) + "'");
} catch (IOException e) {
Log.e(tag, "Error", e);
}
}
}
}
What this should do is listen to Android's network/ethernet interface
and output the recieved data (if there is any). What I get is nothing.
Android does not say that there is an error in Logcat or that anything
is received. This seems to tell me that the information is not being
redirected properly to the emulator.
Any thoughts on getting this redirection business settled?
