Udp broadcast is received, with the above code. In my case i am receiving packets mainly strings from a server at quick constant intervals, all works fine apart from some packet loss(UDP signals are not reliable) my actual problem is after using the service for a long time i am not receiving any signal from the server. Is this because android is killing our service or Thread, or is it because of the the system buffer overflow. I have no insight in network programming and i am stuck. Is there any way we could detect that the thread is stoped and we are not receiving any signals from the server any more and thus restart the whole process?

bind failed: EADDRNOTAVAIL (Cannot assign requested address) - answer:
socket = new DatagramSocket(port, broadcastIP); change to this ---> socket = new DatagramSocket(port);
how i can send message with that service active? port is busy? can u help?

Hi can anyone help me please . I want to listen on port number 15000 for a UDP packet .
I don't know if the IP is necessary as well . I'm trying to listen to a UDP packet sent from infinite flight app on my device and I don't know what IP address the app is sending the UDP port# is 15000
