Android Broadcast UDP Looping
I am currently sending out a DatagramPacket on a DatagramSocket and I receive just fine.. the problem is that I am receiving the packet I sent out. If I call the receive twice then it times out. Is there a way to ignore the first packet and receive the second.
Here is my code..
socket = new DatagramSocket(8001);
socket.setBroadcast(true);
socket.setReuseAddress(false);
DatagramPacket packet = new DatagramPacket(databytes, 7,
getBroadcastAddress(), 8001);
socket.send(packet);
String localAddress = socket.getLocalAddress().toString();
byte[] buf = new byte[1024];
DatagramPacket receivepacket = new DatagramPacket(buf, buf.length);
socket.setSoTimeout(5000);
String temp = "";
String delims = "[/]";
while(true)
{
开发者_开发知识库 try{
socket.receive(receivepacket);
temp = receivepacket.getAddress().toString();
temp = temp.split(delims)[0];
if(temp != localAddress)
{
}else
{
m_IPAddress = temp;
break;
}
}catch (SocketException e){
} catch (IOException e){
String temp1 = e.toString();
}
}
Check to see if the address is bound to one of your interfaces.
