在 Gradle 中通过 Build Flavors 使用替代资源

Question

我已阅读官方文档以及此处的其他几个问题，无论我尝试什么，我的备用资源都不会加载。请ELI5！如果我有以下产品风味

productFlavor {
    flavor1 {
        applicationId "com.packagename.flavor1"
    }
}

我究竟应该在我的项目层次结构中的哪里创建替代资源文件夹，以及我究竟需要如何更改我的 build.gradle 文件以便它知道在构建特定风格时查看所述位置？文档让这听起来很容易，但我整个下午都在尝试不同的变化，但没有任何运气。我误会了什么？

编辑：build.gradle

Answer 1

确保您在正确的路径中创建了文件夹。

应该是app/src/flavor1/res。

为了更有意义，您的主要资源位于src/main/res。

注意：这可能是一个错字，但您的代码应该是 productFlavors { 而不是 productFlavor {
