if using wifi, need use ip address of pc on wifi network. can find @ command line ifconfig (linux) or ipconfig (windows)

if using usb adb connection, can't this, can set adb port forward (see developer docs) pc phone, , have pc connect it's loopback interface , port, forwarded unprivileged port number on phone application should listening. have tcp or whatever connection can push data on in either direction. pc has initiator set connection - adb not support "reverse tethering" in phone initiates network-over-usb connections pc in way supported android emulator.
