Android Studio - 为Gradle中的ManifestPlaceholders分配多个值

Question

我的项目有两个环境 Prod 另一个是暂存。因此，每当我必须构建任何环境时，我都必须更改多个键，例如地图键，标签名称和清单中的其他内容。所以我搜索并找出了一些解决方案， manifestPlaceholders 就是其中之一。

现在我想做的是在 manifestPlaceholders 中分配多个值。那么我可以在其中放置多个值，是的，然后如何在其中放置多个值。以下是 manifestPlaceholders

的代码

buildTypes {
    debug {
        manifestPlaceholders = [ google_map_key:"your_dev_key"]
    }
    release {
        manifestPlaceholders = [ google_map_key:"prod_key"]
    }
}

Answer 1

我通过添加多个 manifestPlaceholders 值解决了我的问题，如下面的代码。将此添加到我的模块build.gradle。

productFlavors {
        staging {
            applicationId "xxxxxxxxxxx"
            manifestPlaceholders = [ google_map_key:"xxxxxxxxxx", app_label_name:"xxxxxxx"]
            buildConfigField 'String', 'BASE_URL', '"xxxxxxxxxx"'
        }
        prod {
            applicationId "xxxxxxxxxxx"
            manifestPlaceholders = [ google_map_key:"xxxxxxxxxx", app_label_name:"xxxxxxx"]
            buildConfigField 'String', 'BASE_URL', '"xxxxxxxxxx"'
        }
    }

修改 您也可以将resValue用作评论中建议的Emanuel Moecklin。

productFlavors {
            staging {
                applicationId "xxxxxxxxxxx"
                manifestPlaceholders = [ google_map_key:"xxxxxxxxxx", app_label_name:"xxxxxxx"]
                buildConfigField 'String', 'BASE_URL', '"xxxxxxxxxx"'
                resValue "string", "base_url", "xxxxxxxxxx"
            }
            prod {
                applicationId "xxxxxxxxxxx"
                manifestPlaceholders = [ google_map_key:"xxxxxxxxxx", app_label_name:"xxxxxxx"]
                buildConfigField 'String', 'BASE_URL', '"xxxxxxxxxx"'
                resValue "string", "base_url", "xxxxxxxxxx"
            }
        }

Answer 2

您可以轻松设置/更改多个manifestPlaceholders值。您可以一次定义所有值，如答案中所示，也可以逐个定义。

defaultConfig {
    // initialize more values
    manifestPlaceholders = [ google_map_key:"xxxxxxxxxx", app_label_name:"xxxxxxx"]
    // or this way
    manifestPlaceholders.google_map_key = "xxxxxxxxxx"
    manifestPlaceholders.app_label_name = "xxxxxxxxxx"
}

productFlavors {
    staging {
    }
    prod {
        // use some different value for prod
        manifestPlaceholders.google_map_key = "yyyyyyyyyy"
    }
}

我已经提到了构建类型和风格

buildTypes {
    release {
        minifyEnabled true
        proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
        resValue "string", "google_maps_key", "release google map key"
    }
    debug {
        minifyEnabled false
        proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
        resValue "string", "google_maps_key", "debug google map key"
    }
}
productFlavors {
    alpha {
        applicationId = "com.example.alpha"
        resValue 'string', 'app_name', 'alphaapp'
        resValue "string", "maps_api_key", "XXXXXXXXXXXXXXXXXXXXX"
    }
    beta {
        applicationId = "com.example.beta"
        resValue 'string', 'app_name', 'betaapp'
        resValue "string", "maps_api_key", "XXXXXXXXXXXXXXXXXXXXXX"
    }
}
