Catatan: Halaman ini merujuk ke paket Camera2. Kecuali aplikasi Anda memerlukan fitur tingkat rendah tertentu dari Camera2, sebaiknya gunakan CameraX. CameraX dan Camera2 mendukung Android 5.0 (level API 21) dan versi yang lebih baru.
Camera2 menyediakan Extensions API untuk mengakses ekstensi yang telah diterapkan oleh produsen perangkat di berbagai perangkat Android. Untuk daftar mode ekstensi yang didukung, lihat Ekstensi kamera.
Gambar berikut menampilkan arsitektur ekstensi kamera.
Gambar 1. Arsitektur Ekstensi Kamera
Aplikasi Camera2 dapat menggunakan ekstensi melalui Camera2 API. Kamera2
API menyediakan cara untuk mengkueri ekstensi yang tersedia, mengonfigurasi ekstensi
kamera, dan berkomunikasi dengan library OEM Ekstensi Kamera. Ini
memungkinkan aplikasi Anda menggunakan ekstensi seperti Night, HDR, Auto, Bokeh, atau
Retouch Wajah.
Menguji perangkat kamera untuk kompatibilitas Camera2 Extensions API
Cuplikan kode berikut memeriksa apakah perangkat mendukung Camera2
API Ekstensi. Ekstensi tidak didukung oleh semua perangkat atau perangkat mungkin mendukung subset
ekstensi. Cuplikan menampilkan daftar ID kamera yang kompatibel dan mendukung
ekstensi kamera.
Membuat CameraExtensionSession dengan Camera2 Extensions API
Camera2 Extensions API, saat digunakan dengan perangkat yang kompatibel, memungkinkan Anda mengakses
ekstensi kamera tertentu. Cuplikan kode berikut menampilkan contoh
cara membuat CameraExtensionSession
untuk menggunakan mode pengambilan malam untuk aplikasi Camera2 yang ada.

Unless your app requires specific, low-level features from Camera2, we recommend using [CameraX](/camerax). Both CameraX and Camera2 support Android 5.0 (API level 21) and higher.\n\n\u003cbr /\u003e\n\nCamera2 provides an Extensions API for accessing [extensions](/training/camera/camera-extensions) that device manufacturers have implemented on various Android devices. For a list of supported extension modes, see [Camera extensions](/training/camera/camera-extensions).\n\nFor a list of devices that support extensions, see [Supported devices](/training/camera/supported-devices).\n\nExtensions architecture\n-----------------------\n\nThe following image shows the camera extensions architecture.\n**Figure 1.**Camera Extensions architecture\n\nA Camera2 application can use extensions through the Camera2 API. The Camera2\nAPI provides ways to query for available extensions, configure an extension\ncamera session, and communicate with the Camera Extensions OEM library. This\nallows your application to use extensions like Night, HDR, Auto, Bokeh, or\nFace Retouch.\n\nTest a camera device for Camera2 Extensions API compatibility\n-------------------------------------------------------------\n\nThe following code snippet checks if the device supports the Camera2\nExtensions API. Extensions are not supported by all devices or the device might support a subset\nof extensions. The snippet returns a list of compatible camera IDs which support\ncamera extensions. \n\n### Kotlin\n\n```kotlin\nprivate fun getExtensionCameraIds(cameraManager: CameraManager): List\u003cString\u003e =\n if (Build.VERSION.SDK_INT \u003e= Build.VERSION_CODES.S) {\n cameraManager.cameraIdList.filter { cameraId -\u003e\n val characteristics = cameraManager.getCameraCharacteristics(cameraId)\n val extensionCharacteristics =\n cameraManager.getCameraExtensionCharacteristics(cameraId)\n val capabilities =\n characteristics.get(CameraCharacteristics.REQUEST_AVAILABLE_CAPABILITIES)\n extensionCharacteristics.supportedExtensions.isNotEmpty() &&\n capabilities?.contains(\n CameraCharacteristics.REQUEST_AVAILABLE_CAPABILITIES_BACKWARD_COMPATIBLE\n ) ?: false\n }\n } else emptyList()\n```\n\n### Java\n\n```java\nprivate List\u003cString\u003e getExtensionCameraIds(CameraManager cameraManager)\n throws CameraAccessException {\n if (Build.VERSION.SDK_INT \u003e= Build.VERSION_CODES.S) {\n return Arrays.stream(cameraManager.getCameraIdList()).filter(cameraId -\u003e {\n try {\n CameraCharacteristics characteristics =\n cameraManager.getCameraCharacteristics(cameraId);\n CameraExtensionCharacteristics extensionCharacteristics =\n cameraManager.getCameraExtensionCharacteristics(cameraId);\n IntStream capabilities =\n Arrays.stream(\n characteristics.get(\n CameraCharacteristics.REQUEST_AVAILABLE_CAPABILITIES\n )\n );\n return !extensionCharacteristics.getSupportedExtensions().isEmpty() &&\n capabilities.anyMatch(capability -\u003e capability == CameraCharacteristics\n .REQUEST_AVAILABLE_CAPABILITIES_BACKWARD_COMPATIBLE\n );\n } catch (CameraAccessException e) {\n throw new RuntimeException(e);\n }\n }).collect(Collectors.toList());\n } else {\n return Collections.emptyList();\n }\n}\n```\n\nCreate a CameraExtensionSession with the Camera2 Extensions API\n---------------------------------------------------------------\n\nThe Camera2 Extensions API, when used with compatible devices, lets you access\ncertain camera extensions. The following code snippet showcases an example of\nhow to create a [`CameraExtensionSession`](https://developer.android.com/reference/android/hardware/camera2/CameraExtensionSession)\nfor using night capture mode for an existing Camera2 application. \n\n### Kotlin\n\n```kotlin\nprivate val captureCallbacks = object : CameraExtensionSession.ExtensionCaptureCallback() {\n // Implement Capture Callbacks\n}\nprivate val extensionSessionStateCallback = object : CameraExtensionSession.StateCallback() {\n override fun onConfigured(session: CameraExtensionSession) {\n cameraExtensionSession = session\n try {\n val captureRequest =\n cameraDevice.createCaptureRequest(CameraDevice.TEMPLATE_PREVIEW).apply {\n addTarget(previewSurface)\n }.build()\n session.setRepeatingRequest(\n captureRequest,\n Dispatchers.IO.asExecutor(),\n captureCallbacks\n )\n } catch (e: CameraAccessException) {\n Snackbar.make(\n previewView,\n \"Failed to preview capture request\",\n Snackbar.LENGTH_SHORT\n ).show()\n requireActivity().finish()\n }\n }\n\n override fun onClosed(session: CameraExtensionSession) {\n super.onClosed(session)\n cameraDevice.close()\n }\n\n override fun onConfigureFailed(session: CameraExtensionSession) {\n Snackbar.make(\n previewView,\n \"Failed to start camera extension preview\",\n Snackbar.LENGTH_SHORT\n ).show()\n requireActivity().finish()\n }\n}\n\nprivate fun startExtensionSession() {\n val outputConfig = arrayListOf(\n OutputConfiguration(stillImageReader.surface),\n OutputConfiguration(previewSurface)\n )\n val extensionConfiguration = ExtensionSessionConfiguration(\n CameraExtensionCharacteristics.EXTENSION_NIGHT,\n outputConfig,\n Dispatchers.IO.asExecutor(),\n extensionSessionStateCallback\n )\n cameraDevice.createExtensionSession(extensionConfiguration)\n}\n```\n\n### Java\n\n```java\nprivate CameraExtensionSession.ExtensionCaptureCallback captureCallbacks =\n new CameraExtensionSession.ExtensionCaptureCallback() {\n // Implement Capture Callbacks\n };\n\nprivate CameraExtensionSession.StateCallback extensionSessionStateCallback =\n new CameraExtensionSession.StateCallback() {\n @Override\n public void onConfigured(@NonNull CameraExtensionSession session) {\n cameraExtensionSession = session;\n try {\n CaptureRequest.Builder captureRequestBuilder =\n cameraDevice.createCaptureRequest(CameraDevice.TEMPLATE_PREVIEW);\n captureRequestBuilder.addTarget(previewSurface);\n CaptureRequest captureRequest = captureRequestBuilder.build();\n session.setRepeatingRequest(captureRequest, backgroundExecutor, captureCallbacks);\n } catch (CameraAccessException e) {\n Snackbar.make(\n previewView,\n \"Failed to preview capture request\",\n Snackbar.LENGTH_SHORT\n ).show();\n requireActivity().finish();\n }\n }\n\n @Override\n public void onClosed(@NonNull CameraExtensionSession session) {\n super.onClosed(session);\n cameraDevice.close();\n }\n\n @Override\n public void onConfigureFailed(@NonNull CameraExtensionSession session) {\n Snackbar.make(\n previewView,\n \"Failed to start camera extension preview\",\n Snackbar.LENGTH_SHORT\n ).show();\n requireActivity().finish();\n }\n };\n\nprivate void startExtensionSession() {\n ArrayList\u003cOutputConfiguration\u003e outputConfig = new ArrayList\u003c\u003e();\n outputConfig.add(new OutputConfiguration(stillImageReader.getSurface()));\n outputConfig.add(new OutputConfiguration(previewSurface));\n ExtensionSessionConfiguration extensionConfiguration = new ExtensionSessionConfiguration(\n CameraExtensionCharacteristics.EXTENSION_NIGHT,\n outputConfig,\n backgroundExecutor,\n extensionSessionStateCallback\n );\n}\n```\n\nAdditional resources\n--------------------\n\nFor more information, see\n[`CameraExtensionCharacteristics`](/reference/android/hardware/camera2/CameraExtensionCharacteristics)\nand view the public [Camera2 Extensions API samples](https://github.com/android/camera-samples/tree/master/Camera2Extensions)\nfor more."]]
