构建要在代码中使用的gradle变量，具体取决于flavor和build类型 [英] build gradle variables to be used in code depending on flavor AND build type

问题描述

有没有办法在我的代码中使用build.gradle中的变量，这取决于flavor和buildType？

Is there a way to use variables from build.gradle in my code, which is dependent on flavor AND buildType?

在这个示例中：可以在Gradle中声明一个可用于Java的变量？新资源值仅取决于它是否为调试或发布版本类型。

In this example here: Is it possible to declare a variable in Gradle usable in Java? the new resource value only depends on if its a debug or release build type.

我想要的是每个可能的buildVariant的一个变量。

What I would like to have is one variable for each possible buildVariant.

所以类似于：

flavor1Debug   => resValue "string", "app_name", "App 1 Debug"
flavor1Release => resValue "string", "app_name", "App 1"
flavor2Debug   => resValue "string", "app_name", "App 2 Debug"
flavor2Release => resValue "string", "app_name", "App 2"

有没有一个很好的方法来做到这一点通过build.gradle或其他不包含switch或if else语句的方式？

Is there a nice way to do this either through build.gradle or another way that doesn't included switches or if else statements?

推荐答案

在build.gradle中为你的应用程序，你可以实现这一点的方法是：

In build.gradle for your app, one way you could achieve this would be:

buildTypes {
    debug {
        productFlavors.flavor1.buildConfigField "String", "app_name", "\"App 1 Debug\""
        productFlavors.flavor2.buildConfigField "String", "app_name", "\"App 2 Debug\""
    }
    release {
        productFlavors.flavor1.buildConfigField "String", "app_name", "\"App 1\""
        productFlavors.flavor2.buildConfigField "String", "app_name", "\"App 2\""
    }
}

请注意，您需要在buildTypes之前定义productFlavors {}块。

Note that you'll want to define your productFlavors{} block before your buildTypes.
