                Connect to adb over a network. Useful for running jenkins in 'the cloud', but testing on real devices locally.
              
          
    Connect your devices to a pi that has been configured like below.
Pi Setup

Download raspbian etc, go through normal setup.
Setup networking

This will let you find your pi locally using it's name, e.g. ping davepi.local
sudo apt-get update

sudo apt-get install avahi-daemon
