Extension functions

Geospatial.checkVpsAvailabilityAsync

Artifact: androidx.xr.arcore:arcore-guava

View Source

Added in 1.0.0-alpha12

fun Geospatial.checkVpsAvailabilityAsync(
    session: Session,
    latitude: Double,
    longitude: Double
): ListenableFuture<VpsAvailabilityResult>

Gets the availability of the Visual Positioning System (VPS) at a specified horizontal position.

The availability of VPS in a given location helps to improve the quality of Geospatial localization and tracking accuracy.

This launches an asynchronous operation used to query the Google Cloud ARCore API. It may be called without calling Session.configure.

Your app must be properly set up to communicate with the Google Cloud ARCore API in order to obtain a result from this call, otherwise the result will be VpsAvailabilityNotAuthorized.

Parameters
`session: Session`	the current `Session`
`latitude: Double`	the latitude in degrees
`longitude: Double`	the longitude in degrees

Returns
`ListenableFuture<VpsAvailabilityResult>`	a `ListenableFuture` that will complete with the `VpsAvailabilityResult`

Anchor.persistAsync

Artifact: androidx.xr.arcore:arcore-guava

View Source

Added in 1.0.0-alpha12

fun Anchor.persistAsync(session: Session): ListenableFuture<UUID>

Stores this anchor in the application's local storage so that it can be shared across sessions.

Parameters
`session: Session`	the `Session` to use for the coroutine context

Returns
`ListenableFuture<UUID>`	a `ListenableFuture` that returns a `UUID` that uniquely identifies this anchor

Throws
`IllegalStateException`	if `Session.config` is set to `Config.AnchorPersistenceMode.DISABLED`, or if there was an unexpected error persisting the anchor (e.g. ran out of memory)
