设备不适用于“main.dart”配置

Question

Before anyone points me to this link I would like to mention, that I don't think these are directly related.

As one can see my flutter doctor -v command is error free:

[✓] Connected device (1 available)

• No issues found!

Yet I to have the issue of a grayed out emulator device with the message Device not applicable for the “main.dart” configuration like this:

I can now only start the emulator using the dropdown menu <no device> like this:

Interestingly I am then actually able to run my app on the device, while the device is still grayed out:

Flutters hot-reloading feature seems to not work properly though.

I have already added the main folder to the project as suggested here and I also made sure to change NO SDK to ANDROID API PLATFORM as suggested in the same link. All dependencies in Project Structure > Modules are found by Android Studio. I cloned the Flutter SKD from the stable branch on GitHub .

Does anyone have an idea why my setup is behaving this way?

Answer 1

It solved my problem:

1- Make sure Flutter plugin is installed in android studio, you can install the plugin from file > setting > plugin

2- choose flutter SDK path from File > setting> Language & Framework > flutter.

Answer 2

Close Android Studio and Run again as Administrator

Answer 3

I have the same issue before.

• Uninstall Flutter and Dart plugin from Android Studio then reinstall Flutter (Dart will be installed automatically)
• Remove created emulators from AVD Manager and create new one
• Try making new project, and set SDK version same as emulators API version or lower from File > Project Structure...

Hopefully worked for you.
