为react原生android项目添加产品口味

Question

我正试图为现有的react原生项目添加如下内容：

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

Error: Duplicate resources

我尝试了一系列不同的解决方案，清理项目，运行package.json中的命令以捆绑到temp目录等。我认为build.gradle文件没有正确配置以支持添加口味，或者我没有正确地执行。

任何帮助都将非常感谢，下面是我的gradle文件（很少重命名为示例）：

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"

task copyDownloadableDepsToLibs(type: Copy) {

在创建APK之前，我使用package.json中的命令(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)。

似乎一旦我运行这个命令，我的默认drawables就会与flavortwo drawables发生冲突，并最终得到重复的资源

在Android/app/src/main/res drawable-hdpi、drawable-mdpi、drawable-xhdpi、drawable-xxhdpi和raw文件夹中删除它并添加到Android/app/build.gradle文件中

android {
...    
aaptOptions {
            cruncherEnabled = false
        }

然后./Dradlew在android studio中清理、无效缓存/restart，然后构建签名的APK。
