How to get current flavor in gradle

I have two product flavors for my app:

productFlavors {
    europe {
        buildConfigField("Boolean", "BEACON_ENABLED", "false")
    }

    usa {
        buildConfigField("Boolean", "BEACON_ENABLED", "true")
    }
}

Now I want to get the current flavor name (which one I selected in Android Studio) inside a task to change the path:

task copyJar(type: Copy) {
    from('build/intermediates/bundles/' + FLAVOR_NAME + '/release/')
}

How can I obtain FLAVOR_NAME in Gradle?

Thanks

Solution 1:

How to get current flavor name

I have developed the following function, returning exactly the current flavor name:

def getCurrentFlavor() {
    Gradle gradle = getGradle()
    String  tskReqStr = gradle.getStartParameter().getTaskRequests().toString()

    Pattern pattern

    if( tskReqStr.contains( "assemble" ) )
        pattern = Pattern.compile("assemble(\\w+)(Release|Debug)")
    else
        pattern = Pattern.compile("generate(\\w+)(Release|Debug)")

    Matcher matcher = pattern.matcher( tskReqStr )

    if( matcher.find() )
        return matcher.group(1).toLowerCase()
    else
    {
        println "NO MATCH FOUND"
        return ""
    }
}

You need also

import java.util.regex.Matcher
import java.util.regex.Pattern

at the beginning or your script. In Android Studio this works by compiling with "Make Project" or "Debug App" button.

How to get current build variant

def getCurrentVariant() {
    Gradle gradle = getGradle()
    String tskReqStr = gradle.getStartParameter().getTaskRequests().toString()

    Pattern pattern

    if (tskReqStr.contains("assemble"))
        pattern = Pattern.compile("assemble(\\w+)(Release|Debug)")
    else
        pattern = Pattern.compile("generate(\\w+)(Release|Debug)")

    Matcher matcher = pattern.matcher(tskReqStr)

    if (matcher.find()){
        return matcher.group(2).toLowerCase()
    }else{
        println "NO MATCH FOUND"
        return ""
    }
}

How to get current flavor applicationId

A similar question could be: how to get the applicationId? Also in this case, there is no direct way to get the current flavor applicationId. Then I have developed a gradle function using the above defined getCurrentFlavor function as follows:

def getCurrentApplicationId() {
    def currFlavor = getCurrentFlavor()

    def outStr = ''
    android.productFlavors.all{ flavor ->

        if( flavor.name==currFlavor )
            outStr=flavor.applicationId
    }

    return outStr
}

Voilà.

Solution 2:

I use this

${variant.getFlavorName()}.apk

to format file name output

Solution 3:

you should use this,${variant.productFlavors[0].name},it will get productFlavors both IDE and command line.

Solution 4:

This is what I used some time ago. I hope it's still working with the latest Gradle plugin. I was basically iterating through all flavours and setting a new output file which looks similar to what you are trying to achieve.

applicationVariants.all { com.android.build.gradle.api.ApplicationVariant variant ->
    for (flavor in variant.productFlavors) {
        variant.outputs[0].outputFile = file("$project.buildDir/${YourNewPath}/${YourNewApkName}.apk")
    }
}
