Gradle: Multi-Dimension Flavor ApplicationId

Question

I have a relatively complicated project that requires two flavor dimensions for each app. I\'ve rewritten it much more simply in the example below:

flavorDim         


        

Answer 1

Gradle has an extras property built in, so you could do this without defining a class.

Would look something like this, might have made a typo or two:

productFlavors {
    blue {
        flavorDimension "color"
        ext.squareId = "yourAppId"
        ext.circleId = "yourAppId"
    }

    android.applicationVariants.all { variant ->
        def flavors = variant.getFlavors()
        if (flavors[0].name.equals("square")){
            variant.mergedFlavor.setApplicationId(flavors[1].ext.squareId)
        } ...
    }

Answer 2

I found a solution following from this example here: Gradle Android Plugin - add custom flavor attribute?

If you add a class like this to your gradle file you can add custom attributes to a productFlavor

class AppIdExtension {
    String squareId
    String circleId

    AppIdExtension(String sId, String cId){
        squareId = sId
        circleId = cId
    }

    public void setSquareId(String id){
        squareId = id
    }

    public String getSquareId(){
        squareId
    }

    public void setCircleId(String id){
        circleId = id
    }

    public String getCircleId(){
        circleId
    }

}

You then add this to extension to each flavor by adding the following code at the start of your android { } section

productFlavors.whenObjectAdded { flavor ->
    flavor.extensions.create("shapeIds", AppIdExtension, "", "")
}

Then inside your product flavor you can set the values for each shape type

blue {
        flavorDimension "color"
        platformIds.squareId "yourAppId"
        platformIds.circleId "yourAppId"
    }

Then finally after your productFlavors { } section you add the following:

android.variantFilter { variant ->
    def applicationId = ""
    def flavors = variant.getFlavors()

  if(flavors[0].name.equals("square")){
      applicationId = flavors[1].platformIds.squareId
   } else if(flavors[0].name.equals("circle")){
      applicationId = flavors[1].platformIds.circleId
   }

   variant.getDefaultConfig().applicationId applicationId

}

This may not be the most elegant or efficient way of achieving it, but it is working perfectly for me. Now I can add all of my Ids in the productFlavor section and then the variantFilter sets the correct applicationId depending on the first flavor.

def appId = "my.custom.package"

if (appId == "some.package") { 
     ..... Change conditions based on the flavors maybe defined more variables
}

defaultConfig {
        applicationId "${appId}"
       ...............
}
