:: MORE NOTES:

:: If you want to disconnect from USB, you can connect ADB via wireless:
:: First, connect to USB as normal:
:: Get the WIFI ip address.  There are a couple ways to do this:

:: GET IP ADDRESS:
:: List the nics on the device. You can find the ip address for the wlan there.
adb shell netcfg

:: LISTEN ON A PORT:
:: Have the device listen on port 5555:
adb tcpip 5555

:: Disconnect the device from USB:
:: Connect ADB to the device via the IP address:
adb connect <device-ip-address>

:: Confirm you are connected:
adb devices

:: If the adb connection is ever lost:
:: 1 - Make sure that your host is still connected to the same Wi-Fi network your Android device is.
:: 2 - Reconnect by executing the "adb connect" step again.
:: 3 - Or if that doesn't work, reset your adb host:
adb kill-server
:: and then start over from the beginning:
