How do I include `applicationIdSuffix` in some generated resource value?

Question

Imagine this setup:

android  {
   buildTypes {
        debug {
            applicationIdSuffix ".debug"
        }
   }
   productFlavors {
       foo {
           applicationId defaultConfig.applicationId + '.foo'
       }
   }

}

How can I set up a dynamic string value such as

resValue "string", "package_name", applicationId

so that it includes the applicationIdSuffix for debug builds?

If I add this to defaultConfig, its my defaultConfig's applicationId that is set. If I add this to the flavor configuration, it is missing the applicationIdSuffix (this is null at this level).

Any hints?

The cool part about applicationIdSuffix is that you can use it in flavors as well as in build types. Check this out:

android {
    compileSdkVersion 23
    buildToolsVersion "23.0.2"

    defaultConfig {
        applicationId "dev.bmax.suffixtext"
        minSdkVersion 14
        targetSdkVersion 23
        versionCode 1
        versionName "1.0"
    }

    buildTypes {
        release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
        }
        debug {
            applicationIdSuffix '.debug'
        }
    }

    productFlavors {
        prod {
            applicationIdSuffix '.prod'
        }
        mock {
            applicationIdSuffix '.mock'
        }
    }
}

Now, when I build my 'prodDebug' variant the final application ID is 'dev.bmax.suffixtext.prod.debug', which is what you want if I understand your question correctly.

EDIT

1. You can access the variant's name in a Gradle task like this:

   applicationVariants.all { variant ->
       // Use 'variant.name'
   }
   

2. Gradle Android Plugin version 0.14.3 added support of the variant specific BuildConfigField/resValue:

   applicationVariants.all { variant ->
       variant.resValue "string", "name", "value"
   }
