除了修改android.name，您还可以在MainActivity中实现：

import android.content.Context;
import com.ryanheise.audioservice.AudioServicePlugin;
import io.flutter.embedding.android.FlutterActivity;
import io.flutter.embedding.engine.FlutterEngine;

public class MainActivity extends FlutterActivity {
  @Override
  public FlutterEngine provideFlutterEngine(Context context) {
    return AudioServicePlugin.getFlutterEngine(context);
  }
}
