根据风味和构建类型构建要在代码中使用的 gradle 变量 [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，这取决于风味和 buildType?

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

在此示例中:是否可以在 Gradle 中声明一个可在 Java 中使用的变量? 新的资源值仅取决于它是调试还是发布构建类型.

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.

我希望为每个可能的 buildVariant 设置一个变量.

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

比如:

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"

是否有一种很好的方法可以通过 build.gradle 或其他不包含开关或 if else 语句的方法来做到这一点?

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

在您的应用程序的 build.gradle 中，实现此目的的一种方法是:

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.
