我正在研究React本机应用程序。该应用程序在IOS上运行正常。当我在android上运行应用程序时，出现以下错误
/node_modules/react-native-image-to-base64/android/src/main/java/com/github/xfumihiro/react_native_image_to_base64/ImageToBase64Package.java:25: error: method does not override or implement a method from a supertype
@Override

error Could not install the app on the device, read the error above for details.
Make sure you have an Android emulator running or a device connected and have
set up your Android development environment:

error Command failed: ./gradlew app:installDebug. Run CLI with --verbose flag for more details.
我已经完成了此链接“ https://facebook.github.io/react-native/docs/getting-started”中提到的所有步骤。有人可以帮我吗
