Public functions

registerExtension

fun <T : Any> registerExtension(type: Class<T>, instance: T): Unit

Registers an extension object to the variant object. Extension objects can be looked up during the AndroidComponentsExtension.onVariants callbacks by using the Variant.getExtension API.

This is very useful for third party plugins that want to attach some variant specific configuration object to the Android Gradle Plugin variant object and make it available to other plugins.

Parameters
type: Class<T>

the registered object type (can be a supertype of instance), this is the type that must be passed to the Variant.getExtension API.
instance: T

the object to associate to the AGP Variant object.

Public properties

enableUnitTest

var enableUnitTest: Boolean

Set to true if the variant's has any unit tests, false otherwise. Value is Boolean#True by default.

maxSdk

var maxSdk: Int?

Gets the maximum supported SDK Version for this variant.

minSdk

var minSdk: Int?

Gets or sets the minimum supported SDK Version for this variant. Setting this it will override previous calls of minSdk and minSdkPreview setters. Only one of minSdk and minSdkPreview should be set.

Returns
Int?

the minimum supported SDK Version or null if minSdkPreview was used to set it.

minSdkPreview

var minSdkPreview: String?

Gets or sets the minimum supported SDK Version for this variant as a Preview codename. Setting this it will override previous calls of minSdk and minSdkPreview setters. Only one of minSdk and minSdkPreview should be set.

Returns
String?

the minimum supported SDK Version or null if minSdk was used to set it.

renderscriptTargetApi

var renderscriptTargetApi: Int

Specifies the bytecode version to be generated. We recommend you set this value to the lowest API level able to provide all the functionality you are using

Returns
Int

the renderscript target api or -1 if not specified.

targetSdk

var targetSdk: Int?

Gets or sets the target SDK Version for this variant as a Preview codename. Setting this it will override previous calls of targetSdk and targetSdkPreview setters. Only one of targetSdk and targetSdkPreview should be set.

targetSdk is now managed by GeneratesApkBuilder instead of VariantBuilder.

Returns
Int?

the target SDK Version or null if targetSdkPreview was used to set it.

targetSdkPreview

var targetSdkPreview: String?

Gets or sets the target SDK Version for this variant as a Preview codename. Setting this it will override previous calls of targetSdk and targetSdkPreview setters. Only one of targetSdk and targetSdkPreview should be set.

targetSdkPreview is now managed by GeneratesApkBuilder instead of VariantBuilder.

Returns
String?

the target supported SDK Version or null if targetSdkPreview was used to set it.

unitTestEnabled

var unitTestEnabled: Boolean

Set to true if the variant's has any unit tests, false otherwise. Value is Boolean#True by default.
