You would need to root the phone and cross compile tcpdump or use someone else's already compiled version.

You might find it easier to do these experiments with the emulator, in which case you could do the monitoring from the hosting pc. If you must use a real device, another option would be to put it on a wifi network hanging off of a secondary interface on a linux box running tcpdump.

I don't know off the top of my head how you would go about filtering by a specific process. One suggestion I found in some quick googling is to use strace on the subject process instead of tcpdump on the system.
