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.

I had the same problem today. The device selector in the Android Studio toolbar wouldn’t even show up, but the device was in the list of connected devices when running flutter doctor -v. Yesterday everything worked fine.

I ran the app from the command line with flutter run and after that, the device showed up again in Android Studio and I could run from inside the editor.
