I'm a beginner in Flutter and I've an emulator opened/powered on and android studio doesn't detect it.
Hence I can't run any program because "no device is running". I've tried installing 'Android emulator' in the SDK tools but android studio still cant detect it.
Android Studio device list shows "loading" and no devices connected. Thus, I opened emulator but I cannot run flutter on emulator on Android Studio. After 5 hours I found that the reason is the new Flutter version.
I solved with choose different version of Dart and Flutter!
You need to download 1.17.3 version. Quick download link: Dowloand Flutter SDK 1.17.3 Version
And switch Stable Channel & Dart: 2.8.4, this is important. Also, if you want, you can check all versions of Flutter SDK: Flutter Versions
On MacOS, just write terminal: flutter channel stable
Note: If this answer is not working for you, you can open android module of your flutter app in Android Studio. It can be helpful when you try to add Firebase skills.
I had same problem.
CMD: flutter devices
No devices detected.
CMD: device emulators
Device emulator-5554 is offline.
In Android virtual device manager, I cold boot emulator and it started working.
In a windows platform I did:
If you have ran flutter doctor and there is no issues and if you can run your flutter app in cmd or using VSCode:
Just try to open Android Studio or IntelliJ as administrator by right clicking on the icon. This may list down devices and solve your problem.
The reason may be you have cloned flutter repository or you don't have right permission in flutter installed directory.
Run flutter doctor command to check whats the problem.
In terminal, run the flutter devices command to verify that Flutter recognizes your connected Android device.
Check your flutter plugin whether it is up to date.
And read this flutter run: No connected devices , You may find the solution.
For me (on a Mac) I had the Android SDK installed in a custom location so I needed to set the ANDROID_HOME environment variable. In the terminal you can check what this value is with:
echo $ANDROID_HOME
I added the Android SDK to my .bash_profile (might be a different file if you are using Linux or Windows) for both ANDROID_HOME and PATH.
# already had these
export PATH="$PATH":"/opt/android-sdk/tools"
export PATH="$PATH":"/opt/flutter-sdk/bin"
# added this
export ANDROID_HOME="/opt/android-sdk"
Replace /opt/android-sdk with wherever yours is.
Then I updated the variables with
source .bash_profile
Testing with flutter doctor showed it was working.
flutter doctor
I restarted Android Studio and the emulator worked.
The last version of Flutter 1.17.5 (release the 2th, July) solved this issue for me.
Just flutter upgrade
run Flutter doctor to make sure you install everything.
run Flutter devices to see whether it is detected by flutter or not.
if you can find the your emulator there run flutter run -d <YOUR_EMULATOR_ID>
if you unable to find your emulator there may be you have to accept the android licenses . run flutter doctor --android-licenses to accept.
run flutter emulators to see list of emulators you have.
run flutter emulators --launch <emulator id> to launch
run Flutter devices to check whether emulator is detected by flutter or not.
run flutter run -d <YOUR_DEVICE_ID>
What worked for me is, updating Android Emulator.
Visit SDK Manager
Check whether any updates available for Android Emulator
If available, install the newest version
Hope this would be helpful!!!
I had this issue on Android Studio.
I had an emulator but it was not recognized even though the emulator was open.
I got around this by launching developer mode inside of the actual emulator by following the steps in this link: https://tweaklibrary.com/how-to-enable-developer-mode-on-android/#:~:text=How%20to%20Enable%20Developer%20Options%20On%20Android.%201,one%20of%20the%20most%20powerful%20...%20More%20items
After setting the emulator to developer mode, the emulator phone appeared as an option and when I ran the flutter hello world it appeared on the emulator.

I formatted my computer and installed windows 10 again because I wanted to play and Linux was having problems.
I am trying to install flutter and dart for application development, but he is accusing this error.
Flutter doctor
I tested it before changing the flutter to beta and it recognized the flutter and dart plugins, however I want to leave it in the stable channel.
However, my code doesn't recognize it, I believe it is because of these errors with the flutter and dart plugins.
Code
I already installed the plugins through android studio and also vscode.
I tried to uninstall and install again, restart the computer, set path ...
I managed to solve it, I will leave here the solution for those who had the same problem as me.
I changed the channel to the Master and ran a flutter upgrade.
Now everything is running smoothly.
Maybe some bug with the stable channel, I can't say.
So:
Flutter channel master
Flutter upgrade
VOILĂ
Flutter doctor
Did you install flutter plugin in android studio properly? (Recheck in android studio.)
if yes then remove it and reinstall it.
if (1) not working then update your android studio.
keep your flutter sdk in c drive
if still flutter cannot trace plugin then set flutter sdk and dart sdk manually in android studio.
for dart
for flutter
I got a small problem which accured after reinstalling Android Studio:
Android Studio
Android Studio is not showing Chrome as Device for my Flutter Web project, while flutter doctor shows clearly everything is enabled correctly:
Flutter doctor
I can normally run the flutter project on google chrome using the console or VS Code, but Android Studio does not work. I already checked the Flutter and Dart plugin.
I would be glad if someone who maybe had the same issue or knows how to fix this gets back to me!
Best Regards
Clearly it is not the issue with flutter. It is an issue with your Android Studio installation. You can verify the same by navigating to the your project folder in the terminal (or command prompt) and type
flutter run -d Chrome.
NOTE: The above command works only if you are on master, beta or dev branch and you have already enabled your flutter web support by typing
flutter config --enable-web
I noticed that your path to Android Studio as: C:\Program Files\Android\ Android Studio1
It means that during installation the original Android Studio folder is not deleted. A duplicate folder has been created in the same location. Hence the Android sdk location is must be changed as well.
You can solve this by:
Uninstall Android Studio. Delete the folder at the above location. Reinstall Android Studio. Update sdk path in your sdk manager as well as in your environment variable. (recommended).
Update the sdk folder in the sdk manager as well as your environment variables.
I made my project on Windows computer, now I'm trying to export to ios on friend's Mac. I've been following this tutorial from part 1 all the way to part 5. How to Install and Setup Flutter for App Development on Mac - Part 1. In other words, Xcode is installed, Android Studio with Flutter and dart plugin installed as well. Android Studio recognizes both simulator and plugged iPhone. When I open the project in Android Studio it looks like this:
Note: Both flutter folder and the project folder are located in "exportalex"
Please try to use terminal and hit this: flutter pub get
You need to load all the dependency before run app.
If still you are facing same issue, please run: flutter doctor
Then share screenshot of result.
It shows and when clicked a drop down always shows "Loading...", but nothing ever gets detected.
Even though adb detects the device.
Setting the correct path for "Flutter SDK path" under "Languages & Frameworks/Flutter" in Android Studio settings fixed the problem.
I had installed two flutter copies, the old one was dirty and not working. But I hadn't updated the path for the new copy in Android Studio.
Edit
It's always good to run flutter doctor, when in doubt.
I had the same issue - make sure you enable USB Debugging in Developer Options on your device
I had the same problem, but it was solved reformating my pubspec.yaml file (I had a identation issue)
I had the same issue and none of the comments posted here helped me. After trying many things, I noticed that I had an unstable flutter version by running flutter version, I changed then to a stable version (at the time this post was written it was version 1.17.3) by executing flutter version 1.17.3, then I restarted android studio and flutter finally had recognised my device
you just need to set your android sdk path for the flutter using this command :
flutter config --android-sdk /path/to/Sdk
and you can get your sdk path(/path/to/Sdk) using this command :
echo $ANDROID_HOME
I am unable start android emulator on android version 2.3.3 after android Oreo installation.
At first it worked,but now after a weekend when i ran a project the emulator doesn't pop up.
AVD loading notification is shown as in the below screenshot(dummy screenshot image in reality the notification is different)
But it will not appear,I have completely installed every package related to android Oreo in the sdk tool manager
Still the same result,if anyone has the same issue and have found a solution.Please,help.
Try to use cmd command like
*path_to_your_android_sdk*\tools\emulator -avd *device_name, f.e Nexus_5_API_23*
It should give you some detailed output about what happened wrong or would launch emulator.
Also make sure you are using last version of emulator (you have added screenshots only for SDK).
If nothing works - just remove all related to emulator sdk tools and reinstall them.
