The following code works fine virtually 100% time on all Android device Android 7.0:

DatagramSocket clientSocket = new DatagramSocket();
clientSocket.setSoTimeout(4000);
clientSocket.setReuseAddress(true);        
clientSocket.setBroadcast(true);
...
DatagramPacket dpSend = new DatagramPacket(baSendData, baSendData.length, InetAddress.getByName("239.255.255.250"), 3702);
clientSocket.send(dpSend);

On Android 7.0, only on Android 7.0, clientSocket.send(dpSend) generates the following error occasionally. I want to emphasize "occasionally". It works fine most of the time.

I am wondering if anyone could offer any insight of Android 7.0 to shed some light on why the exception happens only on Android 7.0.

I'm experiencing the same issue. I'm not able to reproduce the exception. It only crashes on Android API version 26 and 27. Did you find a solution? – Thomas Vos Jan 01 '18 at 10:42
