添加产品风味以响应本机 android 项目

Question

我正在尝试为现有的 react native 项目添加风味，如下所示：

 flavorDimensions "default"
productFlavors {
    flavourone {
        dimension "default"
        applicationId "com.example.flavourone"
    }
     flavourtwo {
        dimension "default"
        applicationId "com.example.flavourtwo"
    }
}

但是当我尝试生成一个签名的 apk 时，似乎我的所有可绘制文件都被复制了，我得到：

Error: Duplicate resources

我尝试了很多不同的解决方案，清理项目，运行 package.json 中的命令以捆绑到临时目录等。我认为 build.gradle 文件没有正确配置为支持添加风味，或者我没有正确地做。

任何帮助将不胜感激，以下是我的 gradle 文件（将一些内容重命名为示例）：

project.ext.react = [
    entryFile: "index.js",
]

//using custom react gradle here to get around https://stackoverflow.com/questions/52464842/react-native-duplicate-resources
apply from: "../../node_modules/react-native-sentry/sentry.gradle"
apply from: "../react.gradle"
//apply from: "../../node_modules/react-native/react.gradle"

// Run this once to be able to run the application with BUCK
// puts all compile dependencies into folder libs for BUCK to use
task copyDownloadableDepsToLibs(type: Copy) {
    from configurations.compile
    into 'libs'
}

在制作 apk 之前，我使用 package.json (react-native bundle --entry-file index.js --platform android --dev false --bundle-output android/app/src/main/assets/index.android.bundle --assets-dest android/app/src/main/res) 中的命令。

似乎一旦我运行此命令，我的默认可绘制对象与flavortwo 可绘制对象发生冲突，并以重复资源结束

在 android/app/src/main/res drawable-hdpi、drawable-mdpi、drawable-xhdpi、drawable-xxhdpi、drawable-xxxhdpi、raw文件夹删除后加入android/app/build.gradle文件

android {
...    
aaptOptions {
            cruncherEnabled = false
        }

然后./dradlew clean，invalid caches/restart在android studio中，然后构建签名的apk。
