Question

我想通过在构建时从文件中读取属性来动态添加构建类型。因为有超过100种构建类型，所以我不在build.gradle文件中编写。

谁能帮帮我？

builde.gradle文件：

buildTypes{
    release {
        signingConfig  signingConfigs.myConfig
        runProguard  true
        zipAlign true
        proguardFiles files('proguard.cfg', getDefaultProguardFile('proguard-android.txt'))
    }

samsung {
        initWith release
        versionNameSuffix "samsung"
        packageNameSuffix ".samsung"
    }

    google {
        initWith release
        versionNameSuffix "google"
        packageNameSuffix ".google"
    }
    ...
}

并修改每个构建清单：

android.applicationVariants.all { variant -> 
def propertyList = variant.productFlavors*.name
propertyList.add(variant.buildType.name)

// read property from file
def variantProperties = new Properties()
propertyList.reverse().each { property ->
    def propFile = "channel.properties"
    try {
        file(propFile).withReader { reader ->
            def tmpProps = new Properties()
            tmpProps.load(reader)
            variantProperties.putAll(tmpProps)
        }
    } catch(e) {
        println "[${variant.name}] Failed to load ${propFile}"
    }
}
println "[${variant.name}] manifest properties: ${variantProperties}"
// default channel value is SinaDown
def defaultValue = "16"
def channel = variant.buildType.name
def value = variantProperties.getProperty("${channel}", defaultValue)
println "[Channel]: ${channel} [Value]: ${value}"

// modify AndroidManifest.xml
variant.processManifest.doLast {
    copy {
        from("${buildDir}/manifests") {
            include "${variant.dirName}/AndroidManifest.xml"
        }
        into("${buildDir}/manifests/$variant.name")

        // get the channel value
        def channelValue = variantProperties.getProperty("${channel}", defaultValue)
        println "[Channel]: ${channel} [Value]: ${channelValue}"

        filter {
            String line ->
                line.replaceAll("<meta-data android:name=\"CHANNEL\" android:value=\".*\"/>",
                        "<meta-data android:name=\"CHANNEL\" android:value=\"${channelValue}\"/>")
        }

        // set the path to the modified Manifest:
        def manifestPath = "${buildDir}/manifests/${variant.name}/${variant.dirName}/AndroidManifest.xml"
        variant.processResources.manifestFile = file(manifestPath)
    }
}

}

我知道这个问题很老但我今天必须做类似的事情。从yml文件中读取值以生成风格。而且由于buildTypes和productFlavors都是NamedDomainObjectContainer，这也应该有效。

查看Inject Build Variables into the Manifest然后根据需要调整代码。

我的bluid.gradle文件类似于：

 apply plugin: "pl.softmate.gradle-properties-yaml-plugin"
 def configs = project.ext.properties.configs // configs from the .yml 
 android {
   //...
   configs.each { config ->
    productFlavors.create(config.name, {
      applicationId config.applicationId
      // ...
   })
}

我的yml文件：

---
configs:
  - name: brand1
    applicationId: com.app.brand1
  - name: brand2
    applicationId: com.app.brand2
---

如何在Android Studio的Gradle基础上从文件中动态添加构建类型？
