How to get the build variant at runtime in Android Studio?

Question

I\'d like to get the build variant during runtime, is this possible without any extra config or code?

Answer 1

Here is an example to define and get BuildConfig for different flavor

android {

    defaultConfig {
        ...
    buildTypes {
        ...
    }

    flavorDimensions "default"
    productFlavors {

        develop {
            applicationIdSuffix ".dev"
            versionNameSuffix "-dev"
        }

        staging {
            applicationIdSuffix ".stg"
            versionNameSuffix "-stg"
        }

        production {
            applicationIdSuffix ""
            versionNameSuffix ""
        }
    }

    applicationVariants.all { variant ->

        def BASE_URL = ""

        if (variant.getName().contains("develop")) {
            BASE_URL = "https://localhost:8080.com/"
        } else if (variant.getName().contains("staging")) {
            BASE_URL = "https://stagingdomain.com/"
        } else if (variant.getName().contains("production")) {
            BASE_URL = "https://productdomain.com/"
        }
        variant.buildConfigField "String", "BASE_URL", "\"${BASE_URL}\""

    }
}

Using

BuildConfig.BASE_URL

If you are already flavoring then no need to provide extra string field in your gradle. Just follow simple steps to get the build details:

For build variant : BuildConfig.FLAVOR
For build version code : BuildConfig.VERSION_CODE
For build version name : BuildConfig.VERSION_NAME

Answer 3

You can try with

getPackageName(); 

it will return what you've defined in build.gradle

productFlavours{
  flavour1{
     applicationId 'com.example.package.flavour1'
  }
  flavour2{
     applicationId 'com.example.package.flavour2'
  }
}

Another option would be to create a separate build config variable for each build variant and use it in your code like this:

In your build.gradle file:

productFlavors {

    production {
        buildConfigField "String", "BUILD_VARIANT", "\"prod\""
    }

    dev {
        buildConfigField "String", "BUILD_VARIANT", "\"dev\""
    }       
}

To use it in your code:

if (BuildConfig.BUILD_VARIANT.equals("prod")){ // do something cool }

Look at the generated BuildConfig class.

public final class BuildConfig {
  public static final boolean DEBUG = Boolean.parseBoolean("true");
  public static final String APPLICATION_ID = "com.example.app";
  public static final String BUILD_TYPE = "debug";
  public static final String FLAVOR = "";
  public static final int VERSION_CODE = 1;
  public static final String VERSION_NAME = "";
}
