my ADB manager dosen't show any Device in the List

Issue

I use Ubuntu 16.0 and Android studio 2.1.2 I created some of a virtual device in AVD manager , and also I'm run Genymotion as a virtual device , but when I'm open ADB manager I can't see any device at list !!

Solution

This is usually occurs when your adb daemon is not running. So you need to restart it or just start.

Do do this you can try next two commands in terminal:

adb stop-server
adb start-server
