공간 기능 확인
컬렉션을 사용해 정리하기
내 환경설정을 기준으로 콘텐츠를 저장하고 분류하세요.
공간 기능은 사용자가 앱 또는 시스템과 상호작용할 때 변경될 수 있으며 앱 자체에서 변경할 수도 있습니다(예: 홈 공간 또는 전체 공간으로 이동). 문제를 방지하려면 앱에서 공간 기능을 확인하여 현재 환경에서 지원되는 API를 결정해야 합니다.
XR용 Jetpack Compose를 사용하여 공간 기능 확인
XR용 Jetpack Compose는 공간 기능을 확인하기 위한 컴포지션 로컬을 만듭니다. 이를 사용하여 공간 UI, 공간 음향, 환경, 패스스루 또는 3D 콘텐츠가 사용 설정되어 있는지 확인합니다.
LocalSpatialCapabilities.current
를 사용하여 현재 다음과 같은 공간 기능을 사용할 수 있는지 확인할 수 있습니다.
다음 예는 공간 UI가 사용 설정되어 있는지 확인하는 방법을 보여줍니다.
if (LocalSpatialCapabilities.current.isSpatialUiEnabled) {
Subspace {
SpatialPanel(
modifier = SubspaceModifier
.width(1488.dp)
.fillMaxHeight()
) {
AppContent()
}
}
} else {
AppContent()
}
SceneCore를 사용하여 공간 기능 확인
SceneCore 라이브러리를 사용하려면 세션을 만들어야 합니다. 세션이 생성되면 세션에서 spatialCapabilities
를 호출하여 현재 사용 가능한 공간 기능을 쿼리합니다.
공간 기능이 변경될 때 알림을 보내는 콜백 addSpatialCapabilitiesChangedListener
를 구독할 수도 있습니다.
// Example 1: check if enabling passthrough mode is allowed
if (xrSession.scene.spatialCapabilities.hasCapability(
SpatialCapabilities.SPATIAL_CAPABILITY_PASSTHROUGH_CONTROL
)
) {
xrSession.scene.spatialEnvironment.preferredPassthroughOpacity = 1f
}
// Example 2: multiple capability flags can be checked simultaneously:
if (xrSession.scene.spatialCapabilities.hasCapability(
SpatialCapabilities.SPATIAL_CAPABILITY_PASSTHROUGH_CONTROL and
SpatialCapabilities.SPATIAL_CAPABILITY_3D_CONTENT
)
) {
// ...
}

To avoid issues, your app needs to check for spatial capabilities to\ndetermine which APIs are supported in the current environment.\n\nCheck for spatial capabilities using Jetpack Compose for XR\n-----------------------------------------------------------\n\nJetpack Compose for XR creates a Composition Local for checking spatial\ncapabilities. Use this to check whether spatial UI, spatial audio, environments,\npassthrough, or 3D content is enabled.\n\nYou can use [`LocalSpatialCapabilities.current`](/reference/kotlin/androidx/xr/compose/platform/package-summary#LocalSpatialCapabilities()) to check if the following\nspatial capabilities are currently available:\n\n- [`isSpatialUiEnabled`](/reference/kotlin/androidx/xr/compose/platform/SpatialCapabilities#isSpatialUiEnabled()): Indicates whether the application may create spatial UI elements (for example, `SpatialPanel`).\n- [`isContent3dEnabled`](/reference/kotlin/androidx/xr/compose/platform/SpatialCapabilities#isContent3dEnabled()): Indicates whether the application may create 3D objects.\n- [`isAppEnvironmentEnabled`](/reference/kotlin/androidx/xr/compose/platform/SpatialCapabilities#isAppEnvironmentEnabled()): Indicates whether the application may set the environment.\n- [`isPassthroughControlEnabled`](/reference/kotlin/androidx/xr/compose/platform/SpatialCapabilities#isPassthroughControlEnabled()): Indicates whether the application may control the passthrough state.\n- [`isSpatialAudioEnabled`](/reference/kotlin/androidx/xr/compose/platform/SpatialCapabilities#isSpatialAudioEnabled()): Indicates whether the application may use spatial audio.\n\nThe following example shows how to check if spatial UI is enabled:\n\n\n```kotlin\nif (LocalSpatialCapabilities.current.isSpatialUiEnabled) {\n Subspace {\n SpatialPanel(\n modifier = SubspaceModifier\n .width(1488.dp)\n .fillMaxHeight()\n ) {\n AppContent()\n }\n }\n} else {\n AppContent()\n}https://github.com/android/snippets/blob/dd30aee903e8c247786c064faab1a9ca8d10b46e/xr/src/main/java/com/example/xr/compose/SpatialCapabilities.kt#L51-L63\n```\n\n\u003cbr /\u003e\n\nCheck for spatial capabilities using SceneCore\n----------------------------------------------\n\nWhen using the SceneCore library, you'll have to create a [session](/develop/xr/jetpack-xr-sdk/add-session). Once the\nsession is created, call [`spatialCapabilities`](/reference/kotlin/androidx/xr/scenecore/Scene#spatialCapabilities()) on the session to query\nwhich spatial capabilities are currently available.\n\n- [`SPATIAL_CAPABILITY_3D_CONTENT`](/reference/kotlin/androidx/xr/scenecore/SpatialCapabilities#SPATIAL_CAPABILITY_3D_CONTENT()): The activity can create 3D contents.\n- [`SPATIAL_CAPABILITY_APP_ENVIRONMENT`](/reference/kotlin/androidx/xr/scenecore/SpatialCapabilities#SPATIAL_CAPABILITY_APP_ENVIRONMENT()): The activity can set its own environment.\n- [`SPATIAL_CAPABILITY_EMBED_ACTIVITY`](/reference/kotlin/androidx/xr/scenecore/SpatialCapabilities#SPATIAL_CAPABILITY_EMBED_ACTIVITY()): The activity can spatially embed another activity.\n- [`SPATIAL_CAPABILITY_PASSTHROUGH_CONTROL`](/reference/kotlin/androidx/xr/scenecore/SpatialCapabilities#SPATIAL_CAPABILITY_PASSTHROUGH_CONTROL()): The activity can enable or disable passthrough.\n- [`SPATIAL_CAPABILITY_SPATIAL_AUDIO`](/reference/kotlin/androidx/xr/scenecore/SpatialCapabilities#SPATIAL_CAPABILITY_SPATIAL_AUDIO()): The activity can use spatial audio.\n- [`SPATIAL_CAPABILITY_UI`](/reference/kotlin/androidx/xr/scenecore/SpatialCapabilities#SPATIAL_CAPABILITY_UI()): The activity can spatialize itself (for example, adding a spatial panel).\n\nYou can also choose to subscribe to a callback,\n[`addSpatialCapabilitiesChangedListener`](/reference/kotlin/androidx/xr/scenecore/Scene#addSpatialCapabilitiesChangedListener(java.util.function.Consumer)) that notifies you when spatial\ncapabilities have changed.\n\n\n```kotlin\n// Example 1: check if enabling passthrough mode is allowed\nif (xrSession.scene.spatialCapabilities.hasCapability(\n SpatialCapabilities.SPATIAL_CAPABILITY_PASSTHROUGH_CONTROL\n )\n) {\n xrSession.scene.spatialEnvironment.preferredPassthroughOpacity = 1f\n}\n// Example 2: multiple capability flags can be checked simultaneously:\nif (xrSession.scene.spatialCapabilities.hasCapability(\n SpatialCapabilities.SPATIAL_CAPABILITY_PASSTHROUGH_CONTROL and\n SpatialCapabilities.SPATIAL_CAPABILITY_3D_CONTENT\n )\n) {\n // ...\n}https://github.com/android/snippets/blob/dd30aee903e8c247786c064faab1a9ca8d10b46e/xr/src/main/java/com/example/xr/scenecore/SpatialCapabilities.kt#L25-L39\n```\n\n\u003cbr /\u003e\n\nSee also\n--------\n\n- [Create a session](/develop/xr/jetpack-xr-sdk/check-spatial-capabilities)\n- [Transition between HSM and FSM](/develop/xr/jetpack-xr-sdk/transition-home-space-to-full-space)\n- [Add spatial environments to your app](/develop/xr/jetpack-xr-sdk/add-environments)\n- [Add 3D models to your app](/develop/xr/jetpack-xr-sdk/add-3d-models)"]]
