BaseFlavor

The application ID.

See Set the Application ID

Application id suffix. It is appended to the "base" application id when calculating the final application id for a variant.

In case there are product flavor dimensions specified, the final application id suffix will contain the suffix from the default product flavor, followed by the suffix from product flavor of the first dimension, second dimension and so on. All of these will have a dot in between e.g. "defaultSuffix.dimension1Suffix.dimensions2Suffix".

ProGuard rule files to be included in the published AAR.

These proguard rule files will then be used by any application project that consumes the AAR (if ProGuard is enabled).

This allows AAR to specify shrinking or obfuscation exclude rules.

This is only valid for Library project. This is ignored in Application project.

Specifies the flavor dimension that this product flavor belongs to.

When configuring product flavors with Android plugin 3.0.0 and higher, you must specify at least one flavor dimension, using the flavorDimensions property, and then assign each flavor to a dimension. Otherwise, you will get the following build error:

Error:All flavors must now belong to a named flavor dimension.
The flavor 'flavor_name' is not assigned to a flavor dimension.

By default, when you specify only one dimension, all flavors you configure automatically belong to that dimension. If you specify more than one dimension, you need to manually assign each flavor to a dimension, as shown in the sample below:

android {
    ...
    // Specifies the flavor dimensions you want to use. The order in which you
    // list each dimension determines its priority, from highest to lowest,
    // when Gradle merges variant sources and configurations. You must assign
    // each product flavor you configure to one of the flavor dimensions.
    flavorDimensions 'api', 'version'

    productFlavors {
      demo {
        // Assigns this product flavor to the 'version' flavor dimension.
        dimension 'version'
        ...
    }

      full {
        dimension 'version'
        ...
      }

      minApi24 {
        // Assigns this flavor to the 'api' dimension.
        dimension 'api'
        minSdkVersion '24'
        versionNameSuffix "-minApi24"
        ...
      }

      minApi21 {
        dimension "api"
        minSdkVersion '21'
        versionNameSuffix "-minApi21"
        ...
      }
   }
}

Whether Multi-Dex is enabled for this variant.

Text file that specifies additional classes that will be compiled into the main dex file.

Classes specified in the file are appended to the main dex classes computed using aapt.

If set, the file should contain one class per line, in the following format: com/example/MyClass.class

Text file with additional ProGuard rules to be used to determine which classes are compiled into the main dex file.

If set, rules from this file are used in combination with the default rules used by the build system.

Specifies the ProGuard configuration files that the plugin should use.

There are two ProGuard rules files that ship with the Android plugin and are used by default:

Returns whether to enable unbundling mode for embedded wear app. If true, this enables the app to transition from an embedded wear app to one distributed by the play store directly.

Adds a new field to the generated BuildConfig class.

The field is generated as: <type> <name> = <value>;

This means each of these must have valid Java content. If the type is a String, then the value should include quotes.

Specifies a flavor that the plugin should try to use from a given dimension in a dependency.

Android plugin 3.0.0 and higher try to match each variant of your module with the same one from its dependencies. For example, consider if both your app and its dependencies include a "tier" flavor dimension, with flavors "free" and "paid". When you build a "freeDebug" version of your app, the plugin tries to match it with "freeDebug" versions of the local library modules the app depends on.

However, there may be situations in which a library dependency includes a flavor dimension that your app does not. For example, consider if a library dependency includes flavors for a "minApi" dimension, but your app includes flavors for only the "tier" dimension. So, when you want to build the "freeDebug" version of your app, the plugin doesn't know whether to use the "minApi23Debug" or "minApi18Debug" version of the dependency, and you'll see an error message similar to the following:

Error:Failed to resolve: Could not resolve project :mylibrary.
Required by:
    project :app

In this type of situation, use missingDimensionStrategy in the defaultConfig block to specify the default flavor the plugin should select from each missing dimension, as shown in the sample below. You can also override your selection in the productFlavors block, so each flavor can specify a different matching strategy for a missing dimension. (Tip: you can also use this property if you simply want to change the matching strategy for a dimension that exists in both the app and its dependencies.)

// In the app's build.gradle file.
android {
    defaultConfig{
    // Specifies a flavor that the plugin should try to use from
    // a given dimension. The following tells the plugin that, when encountering
    // a dependency that includes a "minApi" dimension, it should select the
    // "minApi18" flavor.
    missingDimensionStrategy 'minApi', 'minApi18'
    // You should specify a missingDimensionStrategy property for each
    // dimension that exists in a local dependency but not in your app.
    missingDimensionStrategy 'abi', 'x86'
    }
    flavorDimensions 'tier'
    productFlavors {
        free {
            dimension 'tier'
            // You can override the default selection at the product flavor
            // level by configuring another missingDimensionStrategy property
            // for the "minApi" dimension.
            missingDimensionStrategy 'minApi', 'minApi23'
        }
        paid {}

}

Specifies a sorted list of flavors that the plugin should try to use from a given dimension in a dependency.

Specifies an alternative resource to keep.

For example, if you are using a library that includes language resources (such as AppCompat or Google Play Services), then your APK includes all translated language strings for the messages in those libraries whether the rest of your app is translated to the same languages or not. If you'd like to keep only the language that your app officially supports, you can specify those languages using the resConfig property, as shown in the sample below. Any resources for languages not specified are removed.

android {
    defaultConfig {
        ...
        // Keeps language resources for only the locale specified below.
        resConfig "en"
    }
}

You can also use this property to filter resources for screen densities. For example, specifying hdpi removes all other screen density resources (such as mdpi , xhdpi, etc) from the final APK.

Note: auto is no longer supported because it created a number of issues with multi-module projects. Instead, you should specify the locale that your app supports, as shown in the sample above. Android plugin 3.1.0 and higher ignore the auto argument, and Gradle packages all string resources your app and its dependencies provide.
