我在现有的 android 项目中添加了一个 React Native 屏幕。
从https://github.com/facebook/react-native/blob/master/local-cli/generator-android/templates/src/app/proguard-rules.pro复制与 react native 相关的 proguard 设置 。
但是我想为我的项目启用混淆，因此注释掉了 -dontobfuscate 这一行
之后，当我在我的 nexus 设备中部署发布版本时，我收到此错误：

此链接确实提到 React-Native 不支持混淆： https ://github.com/facebook/react-native/issues/7530
我想混淆现有的应用程序代码。
