Why can't we send a UDP packet from an Android emulator?

My friend and I have a wireless robot dog connected to a wifi network which our computer is plugged into. The computer is running an Android emulator and we are trying to send a UDP packet to the wireless robot dog. If the dog receives it, it should start sending UDP packets back. The program we wrote works outside of the emulator, and using Wireshark, we see that the packet is sent to the correct IP address and the correct MAC address for the robot. When we attempt to send the packet from the emulator, the dog does not respond how it should if it received the packet. In Wireshark we can see that the emulator sends the packet to the correct IP address for the dog, but not the correct MAC address. It is sending it to the MAC address of the router we are plugged into. We want to specify the packet so that it sends to the correct MAC address but we cannot figure out how to do this.开发者_Python百科 Any help would be great

Old question... but this is probably what you're looking for.. it describes your symptoms.
