添加产品口味以响应本地android项目

问题描述

我正在尝试向现有的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"
    }
}

但是当我尝试生成签名的apk时，似乎所有可绘制文件都被复制了，我得到了：

Error: Duplicate resources

我尝试了很多不同的解决方案，清理项目，运行package.json中的命令以将其捆绑到temp目录等。我认为build.gradle文件未正确配置为支持添加风味，或者我不是正确地做。

任何帮助将不胜感激，这是我的gradle文件（以下内容重命名为示例）：

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。

运行此命令后，我的默认可绘制对象似乎与flavortwo可绘制对象发生冲突，并最终导致资源重复

解决方法

在android / app / src / main / res中 drawable-hdpi，drawable-mdpi，drawable-xhdpi，drawable-xxhdpi，drawable-xxxhdpi和原始文件夹将其删除并添加到android/app/build.gradle文件中

android {
...    
aaptOptions {
            cruncherEnabled = false
        }

然后在Android Studio中./dradlew clean，invalid caches/restart，然后构建签名的APK。
