rysasahrialIf you’re developing a Flutter app using Dart in Android Studio, one of the most common issues developers face is the “No Devices Found” message. This error can be frustrating, especially when you’re eager to test your application. Fortunately, there are several effective solutions you can try to solve this issue quickly.
1. Ensure Dart and Flutter Plugins Are Installed
First, make sure that both Flutter and Dart plugins are installed in Android Studio. Navigate to File > Settings > Plugins, and confirm that these plugins are enabled. Without them, Android Studio won’t detect any connected devices properly.
2. Check Your Android Emulator Setup
Open AVD Manager (Android Virtual Device Manager) and ensure that you have at least one configured virtual device. If none appear, create a new virtual device and start it. After that, go to View > Tool Windows > Device Manager to confirm your emulator is running.
3. Verify Physical Device Connection
If you are using a real device for testing, make sure:
- USB Debugging is enabled (on your Android phone: Settings > Developer options > USB debugging).
- The correct drivers are installed (especially for Windows users).
- You have selected “File Transfer” or “Transferring files” as the USB mode.
4. Run flutter doctor
Use the terminal to run the command:
flutter doctor
This command will give a full diagnostic of your development environment. If any issues are detected with the Android toolchain, they will be highlighted. Follow the suggestions to resolve them.
5. Update Android Studio and SDK Tools
Sometimes, the problem lies in outdated components. Make sure Android Studio is up to date, along with the SDK Platform-Tools and Emulator from the SDK Manager.
6. Restart ADB Server
Try restarting the Android Debug Bridge:
adb kill-server adb start-server
Then reconnect your device or restart the emulator.
7. Configure Environment Variables
Ensure your environment variables such as ANDROID_HOME and PATH include the correct paths to the SDK and Flutter.
For further Flutter-specific setup guidance, refer to the Flutter installation page for platform-specific configurations.
