CameraDeviceSetupCompat

fun isSessionConfigurationSupported(sessionConfig: SessionConfiguration): CameraDeviceSetupCompat.SupportQueryResult

Checks if the SessionConfiguration is supported.

fun isSessionConfigurationSupportedLegacy(
    sessionConfig: SessionConfigurationLegacy
): CameraDeviceSetupCompat.SupportQueryResult

Checks if the set of features in SessionConfigurationLegacy is supported for the given camera.

This method and the legacy classes are provided to allow querying camera device capabilities without the need to call openCamera. It must only be used for devices that do not support CameraDevice.CameraDeviceSetup and will throw an IllegalStateException when used for a cameraId for which isCameraDeviceSetupSupported returns true.

Even on older devices that do not support android.hardware.camera2.CameraDevice.CameraDeviceSetup, if the CameraDevice object can be obtained using openCamera, then isSessionConfigurationSupported should be used as the android.hardware.camera2.CaptureRequest returned by Camera2 generally has more information pre-filled from the template which may change the result.

Note that this method does not, and can not query camera2's isSessionConfigurationSupported, so the returned getSource will never be SOURCE_ANDROID_FRAMEWORK. Additionally, there is a small possibility that the result of Camera2's isSessionConfigurationSupported contradicts the result of this call. In such cases, a RESULT_UNSUPPORTED result can be considered authoritative, but RESULT_SUPPORTED may or may not be correct and is considered best effort.

WARNING: Use this method is discouraged for most developers. isSessionConfigurationSupported should be used wherever possible. This method should only be used if performance is critical on older devices and you understand and protect against the caveats documented above.
