5- Click on the small bug icon next to the Devices tab to attach the debugger.

Android Studio

Click on the "Attach debugger" icon. It's the one on the right in the picture below.

Alternatively you can access this feature from Run > Attach debugger to Android process.

You will be presented with a dialog displaying connected devices and the running apps you can debug.
