Android에서 ARCore 세션 구성
컬렉션을 사용해 정리하기
내 환경설정을 기준으로 콘텐츠를 저장하고 분류하세요.
ARCore 세션을 구성하여 앱의 AR 환경을 빌드합니다.
세션이란 무엇인가요?
모션 추적과 같은 모든 AR 프로세스는
ARCore 내에서 이루어지는 환경 이해, 조명 추정은
세션입니다. Session
는 ARCore로 연결되는 기본 진입점입니다.
API에 액세스할 수 있습니다. AR 시스템 상태를 관리하고 세션 수명 주기를 처리하여
세션을 생성, 구성, 시작 또는 중지합니다. 무엇보다도
앱이 카메라 이미지에 대한 액세스를 허용하는 프레임을 수신하고
있습니다.
세션은 다음 기능을 구성하는 데 사용할 수 있습니다.
ARCore가 설치되어 있고 최신 상태인지 확인
Session
를 만들기 전에 ARCore가 설치되어 있고 최신 상태인지 확인합니다. 만약
ARCore가 설치되지 않아 세션 생성이 실패하고 이후 설치가 이루어집니다.
ARCore를 업그레이드하려면 앱을 다시 시작해야 합니다.

세션 닫기
Session
는 상당한 양의 네이티브 힙 메모리를 소유합니다. 명시적으로 실패한 경우
세션을 닫으면 앱의 네이티브 메모리가 부족해지고 비정상 종료될 수 있습니다. 날짜
AR 세션이 더 이상 필요하지 않다면
출시까지 close()
남음
리소스를 배포합니다 앱에 AR 지원 활동이 하나만 포함된 경우 close()
를 호출합니다.
활동의 onDestroy()
메서드에서 가져올 수 있습니다.

[`Session`](/ar/reference/java/com/google/ar/core/Session) is the main entry point to the ARCore\nAPI. It manages the AR system state and handles the session lifecycle, allowing\nthe app to create, configure, start, or stop a session. Most importantly, it\nenables the app to receive frames that allow access to the camera image and\ndevice pose.\n\nThe session can be used to configure the following features:\n\n- [Lighting Estimation](/ar/develop/lighting-estimation)\n- [Cloud Anchors](/ar/develop/cloud-anchors)\n- [Augmented Images](/ar/develop/augmented-images)\n- [Augmented Faces](/ar/develop/augmented-faces)\n- [Depth API](/ar/develop/depth)\n- [Instant Placement](/ar/develop/instant-placement)\n- [ARCore Geospatial API](/ar/develop/geospatial)\n\nVerify that ARCore is installed and up to date\n----------------------------------------------\n\nBefore creating a `Session`, verify that ARCore is installed and up to date. If\nARCore isn't installed, session creation fails and any subsequent installation\nor upgrade of ARCore requires an app restart. \n\n### Java\n\n // Verify that ARCore is installed and using the current version.\n private boolean isARCoreSupportedAndUpToDate() {\n ArCoreApk.Availability availability = ArCoreApk.getInstance().checkAvailability(this);\n switch (availability) {\n case SUPPORTED_INSTALLED:\n return true;\n\n case SUPPORTED_APK_TOO_OLD:\n case SUPPORTED_NOT_INSTALLED:\n try {\n // Request ARCore installation or update if needed.\n ArCoreApk.InstallStatus installStatus = ArCoreApk.getInstance().requestInstall(this, true);\n switch (installStatus) {\n case INSTALL_REQUESTED:\n Log.i(TAG, \"ARCore installation requested.\");\n return false;\n case INSTALLED:\n return true;\n }\n } catch (UnavailableException e) {\n Log.e(TAG, \"ARCore not installed\", e);\n }\n return false;\n\n case UNSUPPORTED_DEVICE_NOT_CAPABLE:\n // This device is not supported for AR.\n return false;\n\n case UNKNOWN_CHECKING:\n // ARCore is checking the availability with a remote query.\n // This function should be called again after waiting 200 ms to determine the query result.\n case UNKNOWN_ERROR:\n case UNKNOWN_TIMED_OUT:\n // There was an error checking for AR availability.

Failure to explicitly\nclose the session may cause your app to run out of native memory and crash. When\nthe AR session is no longer needed, call\n[`close()`](/ar/reference/java/com/google/ar/core/Session#close()) to release\nresources. If your app contains a single AR-enabled activity, call `close()`\nfrom the activity's `onDestroy()` method. \n\n### Java\n\n // Release native heap memory used by an ARCore session.\n session.close();\n\n### Kotlin\n\n // Release native heap memory used by an ARCore session.\n session.close()\n\nNext steps\n----------\n\n- [ARCore quickstart for Android](/ar/develop/java/quickstart)"]]
