Flutter-intellij: Flutter Intellij/Android Studio plugin shows "no devices" while cli and VSCode show all devices

Created on 20 Jun 2020 · 24Comments · Source: flutter/flutter-intellij

Problem

Both IntelliJ (2020.1C) and Android Studio (4.0) with Flutter Plugin v46 consistently show "no-devices", even though the flutter devices and VSCode show all devices (web / Android)

Running on MacOS Catalina 10.15.5

Steps to Reproduce

This is consistent. Things I've tried to resolve:

Restart the IDEs
Execute flutter config --android-sdk /path/to/sdk
Execute flutter config --android-studio-dir /path/to/studio
Uninstall and reinstall the plugin
Create a new Android AVD
Start the AVD from the device pull-down menu
Starting the IDE with the AVD already running
Adding Android SDK to the system path (so adb works from anywhere

Logs

flutter config output:

Settings:
  enable-macos-desktop: true (Unavailable)
  enable-web: true
  android-sdk: /Users/lior/dev/android_sdk
  android-studio-dir: /Applications/Android Studio.app

I install xcode and it works!
However, I don't understand why xcode is required to run flutter on my android device.
This does not make any sence at all, because I can run flutter in vscode without xcode.
Please look into this

@pennzht
Please try installing xcode flowing the flutter doctor's instrution and see if it can work

This should be fixed in the current dev channel build.

stevemessick on 22 Jun 2020

Thank you, but this is still not working for me. I've updated the plugin to 47.0.3-dev.4 and restarted the IDE.

This the output from flutter devices in terminal:

3 connected devices:

Android SDK built for x86 • emulator-5554 • android-x86    • Android 10 (API 29) (emulator)
Web Server                • web-server    • web-javascript • Flutter Tools
Chrome                    • chrome        • web-javascript • Google Chrome 83.0.4103.106

The plugin UI shows "Loading..." in the device-dropdown, followed by the main.dart configuration, followed by a "No devices" dropdown.

@helin24

We've had some success with closing the re-opening the project without restarting the IDE. You might try the stable channel of the SDK. The problem was caused by a change to the command line tool, but I'm not sure if that change made it into stable yet.

This is working for me with latest master of the engine and the dev plugin.

i've got same issue...
i set sdks into project structure and i tried to switch flutter channel from stable to dev but nothing happens.

i think that issue involved only flutter plugin because flutter sdk works well.
i use it via vscode and i can run a flutter app via vscode or terminal.

flutter doctor said that everything is ok (apart xcode but i don't use it) and it show the physical connected device.

from my android studio i can only run java or kotlin android app (not flutter app).
only with flutter plugin (both in android studio and intellij) i cannot run app directly (but i can do it via intergated terminal).

Thanks for the update @liorgonnen !

@pminel as mentioned above this appears to be fixed in the dev channel of the plugin (at least for the master channel of the SDK). We'll be publishing a new stable release this week, which will have that fix.

stevemessick on 25 Jun 2020

Using the master channel of the SDK and dev channel of the plugin does not fixed this issue.
This has wasted 4 of my days. @stevemessick

I updated the flutter plugin to 47.0.2 in AS4.0. This dose not help either.

Downgrade flutter to version 1.18.0-11.1.pre resolved for me...

cyberdemon8 on 28 Jun 2020

thanks @cyberdemon8.
with flutter 1.18.0-11.1.pre everything works also with android studio and i can run flutter app from it.
for now is the best workaround that i've tried.
i hope soon in a stable channel update to fix the flutter issue.

As you said, it did work well!!!
Thank you very much!

For people seeing this issue, a fix for this has landed in flutter master (https://github.com/flutter/flutter/pull/60546), and is being considered as a hot fix cherry-pick to more stable versions of flutter.

Same bug happend to me when I was on flutter 1.22 --> stable channel.
Luckily I was again able to fix this problem, by switching to the dev channel.
