How do I set my Android app package name based on

Question

I'm building my Android app with the Gradle plugin. I'm using the flavors feature to create four different variants. At the moment, it's a single dimension with four values, but it would be more logical to set it up as two dimensions with two values each. I've got that building, but this is where I run into trouble.

I need each of the four variants to have a different package name. The first three are easy since I have a default and each dimension can override the package, but I need to set a package name for when both non-default dimensions are in play.

flavorDimensions "foo", "bar"
productFlavors {
    boring.flavorDimension "foo"
    charm {
        flavorDimension "foo"
        packageName "com.example.charm"
    }
    strange {
        flavorDimension "bar"
        packageName "com.example.strange"
    }
    // This is the idea of what I want, but it doesn't work because there
    // must be only a single dimension specified here.
    charmStrange {
        flavorDimension "foo", "bar"
        packageName "com.example.charminglystrange"
    }
}

I tried setting it after declaration by looking up the composed flavor variant, but I didn't have much luck. I'm not very familiar with Gradle, so I'm sure there's trickery I haven't employed. Alternately, maybe I could specify the package name in src/charmStrange/AndroidManifest.xml and let the merge sort it out? That seems like it could cause problems in the future.

I had a similar question this answer isn't tested in my case I was appending the product flavor to the app id set by the other dimension, using your example it would append .strange to package com.example.charm

android.applicationVariants.all { variant ->
    def flavorString = variant.getVariantData().getVariantConfiguration().getFlavorName()
    def mergedFlavour = variant.getVariantData().getVariantConfiguration().getMergedFlavor();
    def appId = variant.getVariantData().getVariantConfiguration().getApplicationId();

    if(flavorString.contains("Strange")) {
        mergedFlavour.setApplicationId(appId + ".strange")
    }


}

but in your case you want a full package name so something like

android.applicationVariants.all { variant ->
    def flavorString = variant.getVariantData().getVariantConfiguration().getFlavorName()
    def mergedFlavour = variant.getVariantData().getVariantConfiguration().getMergedFlavor();
    def appId = variant.getVariantData().getVariantConfiguration().getApplicationId();

    if(flavorString.contains("charmStrange")) {
        mergedFlavour.setApplicationId("com.example.charminglystrange)
    }


}

charmStrange might need to be CharmStrange, try playing with it

You will want to set the applicationId, not the packageName:

    productFlavors {
        boring.flavorDimension "foo"
        charm {
            flavorDimension "foo"
            applicationId "com.example.charm"
        }
        strange {
            flavorDimension "bar"
            applicationId "com.example.strange"
        }
        // This is the idea of what I want, but it doesn't work because there
        // must be only a single dimension specified here.
        charmStrange {
            flavorDimension "foo", "bar"
            packageName "com.example.charminglystrange"
        }
    }

Answer 3

You can now set applicationIdSuffix for productFlavors:

android {  
     productFlavors {  
          free {   
               applicationIdSuffix = ".free"  
          }  
          prod {

          } 
     }  
}
