Android adb plug in blank hostname

Question

I use ADB via WiFi to connect to an Android device. When i type

adb connect <device ip> 

I get an error

 empty hostname 

Answer 1

For me, just restarting adb solved the problem

 adb kill-server adb start-server 

Answer 2

You need to change the net.hostname property on your device. The easiest way is to use the setprop command through the root shell on the device.

 setprop net.hostname TypeAnyHostName
