Hi Gail,

This sounds like an issue in Android SDK. Better do the followings and see how it goes

  • Install a fresh copy of the Android SDK again
  • Make sure to put correct paths
  • If you run it on your device, make sure both are(device and the machine) in the same network. 
  • Make sure your Anti-virus / Firewall in your computer  not blocking  your device.

Good luck
