adb devices gives the device shows up as unauthorized.

Answer 1

Solution

1 Connect device(over USB) to computer (WINDOWS).

2 Authorize adb device, so it can communicate(handshake over USB) with computer

3 Check that the device is connected

$adb devices

List of devices attached

SC8SDQWGKBT4JVS4        device

4 Change to tcpip mode

$adb tcpip 5555

restarting in TCP mode port: 5555

5 Connect device(over WIFI) to computer, make sure both are on the same network

$adb connect 192.168.1.100

connected to 192.168.1.100:5555

6 Authorize adb device, so it can communicate(handshake over WIFI) with computer

7 Check that the device is connected

$adb devices

List of devices attached

SC8SDQWGKBT4JVS4        device

192.168.1.100:5555      unauthorized

Although I authorized the device, adb is seeing things differently.

To get things working correctly, unplug device from USB because there is a connection over WIFI.

8 Kill the adb server

$adb kill-server

9 Connect again over WIFI

$adb connect 192.168.1.100

* daemon not running. starting it now on port 5037 *

* daemon started successfully *

connected to 192.168.1.100:5555

10 Finally, Check that the device is connect

$adb devices

List of devices attached

192.168.1.100:5555      device

Device is now authorized, you can start debugging over WIFI.
