add virtual device .... or you can connect your phone with it goto setting > debugger options > tun on usb debugging. After that change mobile setting to file sharing then try again – HussainAbbas Jul 22 '19 at 11:12

First, check that the device is connected properly and USB Debugging is enabled. You can enable debugging in developer options in your android device. Second, open terminal and type the following commands:
adb devices
: This should list the devices connected to the computer. If you see an error sayingadb command not found
, you'll have to add Android SDK to your path. You can find the instructions here: https://9to5google.com/2014/12/02/how-to-install-adb-tools-windows-mac-linux/adb kill-server
: This will kill the ADB Serveradb start-server
: This will start the server.
After you have restarted the adb server, try the 1st command again and you should see your device. After you see the device, restart Android Studio and same will appear in the window.

Solved!! First Update the Android Studio then change the adb.
