Hi Simon,
Yup, we are running TCP keepalives on the server... It's the Android side that we are questioning the proper way to implement..
We will just  implement writeFrame(new Frame(AMQP.FRAME_HEARTBEAT, 0));
when the service wakes up..
thanks very much,

It's possible that enabling TCP keepalives will help:


But you may need them on the client too, which may in turn require 
waking the client up; I'm not sure how that works on Android.
