Android Studio 3.0 with Flutter & Dart plugin not recognizing USB or virtual devices when clicking Play

_From @tomnta on November 14, 2017 19:22_

## Steps to Reproduce

Run "Flutter Devices" in Windows 10 Command Prompt shows that a device is connected.

> flutter devices
> 1 connected device:
> SM N950U1 • ce06xxxxxxxx • android-arm • Android 7.1.1 (API 25)

However, pressing Run in Android Studio 3.x returns this error popup:

> No connected devices found; please connect a device, or see flutter.io/setup for getting started instructions.

https://flutter.io/setup/ guides the user to this link https://flutter.io/setup-windows/#android-setup

And that page has no directions on how to setup the IDE to recognize that you have a device attached or to have it work with the virtual device.

The same error window pops up when you select a virtual device and press Play in Android Studio. However, pressing Play on an Android project works fine with virtual and USB devices.

## Logs

> Run your application with `flutter run` and attach all the log output.
> Run `flutter analyze` and attach any output of that command also.

N/A. The command line tool works fine. The Android Studio plugin has issues.
