I just downloaded android emulator through android studio. Didn't use the GitHub repo to download dmg file. Then I started the S level API android emulator from and manager. Android emulator boots but android studio doesn't detect and doesn't run app on it.
What could be the problem?
Reproduced:
Remove *.lock files in avd folder (Didn't work)
flutter doctor -v

1)Try enabling USB Debugging in the Android emulator itself, as you would do on a real device. Settings-> Developer options-> enable USB Debugging.
2)Probably the project you are running is not compatible (API version/Hardware requirements) with the emulator settings. Check-in your build.gradle file if the target SDK and minimum SDK version are lower or equal to the SDK version of your Emulator.
You should also uncheck Tools > Android > Enable ADB Integration
If your case is different then restart your Android Studio and run the emulator again.
For more info:
Android studio: emulator is running but not showing up in Run App "choose a running device"
Android Studio does not detect the emulator
I went to the AVD Manager and in the options for the particular emulator I selected "Cold Boot Now" and it resolved my issue.

I'm getting this error when I try to run my application on the iOS simulator:
Launching lib/main.dart on iPhone 14 Pro Max in debug mode...
Running Xcode build...
└─Compiling, linking and signing... 9,2s
Xcode build done. 27,9s
Connecting to the VM Service is taking longer than expected...
Still attempting to connect to the VM Service...
If you do NOT see the Flutter application running, it might have crashed. The device logs (e.g. from adb or XCode) might have more details.
If you do see the Flutter application running on the device, try re-running with --host-vmservice-port to use a specific port known to be available.
At the end of the Xcode build done. 27,9s print in the terminal, the App opens in the iOS simulator for a few milliseconds, but is instantly closed, and a crash screen from Xcode is opened.

I solved the problem by removing a package that I had in the application that has the pub google_mobile_ads in its .yaml, and as I am not implementing Ads in this App I did not configure the necessary items in AndroidManifest.xml and Info.plist.

This could be because of compatible issues between flutter and Xcode version. Switch to the previous version and see if the error is there. Try other versions of flutter manually, using flutter version .
You can also run the program from Xcode, and try opening the emulator from there.
You can indeed use
flutter create .
to "repair" the current project to a limited degree.
If the ios/ or android/ folders are missing, they are created.
You can use this to switch native language Java/Kotlin, ObjC/Swift or to get the generated files updated to match newer Flutter versions by deleting the directories and running
flutter create . [options]
You need to re-apply previously made manual changes yourself though.
I am trying to run my existing flutter application and I am getting this exception. How can I solve this issue?
Exception: [!] Your app is using an unsupported Gradle project. To fix this problem, create a new project by running flutter create -t app <app-directory> and then move the dart code, assets and pubspec.yaml to the new project.

Maybe you removed a line from the
project/android/app/build.grade
Try adding this Piece of Code
apply from: "$flutterRoot/packages/flutter_tools/gradle/flutter.gradle"
after the line
apply plugin: 'com.android.application'
I resolve this issue by syncing project with gradle files.In android studio from menu open File option and click option sync project with gradle files.
Could you check this solution The project is using an unsupported version of Gradle
If you have the backup of your project than go to
project/android/app/build.grade
copy all the code and paste it to your project app/build.grade file.
Clean Project
Now Enjoy. Your error will not appear.
Thankyou.
For everyone landing here after making changes to the gradle for firebase or smth, it might seem stupid but check that the autoformat(if you have it enabled) didn't make funny things like putting spaces between "->" or "+=" turning them into "- >" or "+ ="
I'm running Android studio as an administrator in Windows 10. The AVD is a Nexus 5X API 28. I'm trying to run the flutter demo, but the device drop-box still shows "no devices", it only has the "Open Android Emulator" option, which I clicked to start the AVD:

Unlike in a real phone connected via USB, here there is no authorization dialog when I start the AVD. How can I authorize the phone?
This simple solution worked: Wipe data and Cold Boot.
Didn't work:
Note that in the Terminal of the Android studio, adb is not recognized (following flutter installation instructions). You can add the android SDK location path to the PATH environmental variable just to be able to run adb, but this won't give you more information than flutter doctor -v. The android SDK path should be already in Tools|SDK Manager, which is in my case "C:\Users\User\AppData\Local\Android\Sdk", nothing to do with "android-sdk-windows". Killing and restarting adb didn't work.
Logcat shows the message "Please configure Android SDK" (click on "configure", opens "Project Structure" window). The paths to SDK and default JDK are valid. Installing NDK miscofigured something else, so I uninstalled it and left this path field empty. Under "Project", all Version and Repository fields are empty.
You should add ANDROID_HOME variable to your class_path
set ANDROID_HOME=C:\<installation location>\android-sdk-windows
set PATH=%PATH%;%ANDROID_HOME%\tools;%ANDROID_HOME%\platform-tools
Taken from this
After that call flutter doctor -v and flutter devices
