To fix your Flutter app not running on the Android emulator, try these steps:

Run flutter doctor -v to check for setup issues. Ensure the Android SDK is correctly installed and configured. Use Java 11 and the default Gradle version (try flutter clean and rebuild). Verify Android emulator settings (API level, hardware acceleration). Run with detailed logs: flutter run -v. Update Flutter with flutter upgrade. Reinstall the Android emulator or recreate it in Android Studio.
