# ADB Connect android device for building via wifi
# Based on stack over flow answer:
# http://stackoverflow.com/questions/4893953/run-install-debug-android-applications-over-wi-fi
# 
# Usage: 
# 
# 1. Make sure adb command is in executable path
# 
# 2. Connect device by USB and run:
#    adb_wifi
# 
# 3. To disconnect run:
#    adb_wifi -s
# 
#
# 4. Optional to make this command executable anywhere
#       - make script executable: chmod u+x adb_wifi
#       - put script in executable path
#       
#       
#  Optional usage:
#  
#   if connection disconnects due to device sleep, 
#   then we can reconnect wirelessly using cached ip address
#  
#  Connect to last used ip ( in last_adb_wifit.txt ):
#   adb_wifi -l  
#
