question

Hello, I have an app, which sends datagram packets (DatagramPacket) over multicast socket (MulticastSocket). It works for other android platforms, but on Kindle HD/HDX the packets are not sent. In the emulator, I do reach the point in my code, where the data is actually send. But it is not received by the other party. Is there something special I should perhaps configure to make it work? Of course, I have this line in my Android.manifest Thanks, Andrei
