adb is usually used over USB. However, it is also possible to use over Wi-Fi, as described here.
  1. Connect your Android device and adb host computer to a common Wi-Fi network accessible to both. Beware that not all access points are suitable; you may need to use an access point whose firewall is configured properly to support adb.
    Note: If you are attempting to connect to an Android Wear device, force it to connect to Wi-Fi by shutting off Bluetooth on the phone connected to it.
  2. Connect the device to the host computer with a USB cable.
  3. Set the target device to listen for a TCP/IP connection on port 5555.
    $ adb tcpip 5555
  4. Disconnect the USB cable from the target device.
  5. Find the IP address of the Android device. For example, on a Nexus device, you can find the IP address at Settings > About tablet (or About phone) > Status > IP address. Or, on an Android Wear device, you can find the IP address at Settings > Wi-Fi Settings > Advanced > IP address.
  6. Connect to the device, identifying it by IP address.
    $ adb connect device_ip_address
  7. Confirm that your host computer is connected to the target device:
    $ adb devices
    List of devices attached
    device_ip_address:5555 device
You're now good to go!
