我刚开始接触React-Native。我使用Atom作为编辑器，Genymotion作为模拟器。代码运行得很好。但是当涉及到生成发布APK时，我遇到了困难。
我按照https://facebook.github.io/react-native/docs/signed-apk-android中的教程进行操作，但是出现了一些错误。
经过一些研究，我运行了以下命令：
- react-native bundle --platform android --dev false --entry-file index.js --bundle-output android/app/src/main/assets/index.android.bundle --assets-dest android/app/src/main/res
- cd android && ./gradlew assembleRelease
但是我遇到了很多错误。

一些研究告诉我必须清空 res 文件夹，我按此操作了，但在运行 ./gradlew assembleRelease 后我还是遇到了其他错误。

我希望在进行Facebook React-native网站配置后，能够得到一个APK文件。但是不知道出了什么问题。
我不知道如何解决这个问题。请问有什么建议吗？
