Android device is not connected to USB for debugging (Android studio)

Question

I am trying to debug my application using a real device instead on the emulator. When I try to connect, it gives me the message:

USB device not found<

Answer 1

I just ran adb command prompt and hit 'adb devices' and it showed daemon was not running. It installed itself and now i can able to see android devices there.

C:\...\...\source\repos\ABC\ABC\Ex.Android>adb devices
List of devices attached
* daemon not running; starting now at tcp:5037
* daemon started successfully
