init
@NonNull static fun init(): ListenableFuture<ExtensionsManager.ExtensionsAvailability!>
Initialize the extensions asynchronously.
This should be the first call to the extensions module. An application must wait until the ListenableFuture completes before making any other calls to the extensions module.
isExtensionAvailable
static fun isExtensionAvailable(
effectMode: ExtensionsManager.EffectMode!,
lensFacing: Int
): Boolean
Indicates whether the camera device with the lensFacing can support the specific extension function.
