ApkOutput

@Incubating
interface ApkOutput

Provides an ordered collection of APK batches, each intended for local installation, facilitating staged installations.

An instance of ApkOutput can be obtained via ApplicationVariant.outputProviders

As an example , let's take a Gradle org.gradle.api.Task that needs all the Apks for local deployment:

abstract class FetchApkTask: DefaultTask() {
  @get:Internal
  abstract val apkOutput: Property<com.android.build.api.variant.ApkOutput>

  @TaskAction
  fun execute() {
    def apkInstallGroups = apkOutput.apkInstallGroups
        for(installGroup: installGroups) {
            installOnDevice(installGroup.apks)
       }
  }
}
def taskProvider = tasks.register<FetchApkTask>("installAppApks")
androidComponents {
    onVariants(selector().withName("debug")) { variant ->
        val appVariant = variant as? ApplicationVariant
        if (appVariant != null) {
            appVariant.outputProviders.provideApkOutputToTask(taskProvider, FetchApkTask::getOutput, DeviceSpec("testDevice", 33, "", [], true))
        }
    }
}
