+     * For example, a physical shutter may have been uncovered or covered,
+     * or a camera may have been covered or uncovered by an add-on keyboard
+     * or other accessory.
+     *
+     * The state is a bitfield of potential states, and some physical configurations

+     * the appropriate camera configuration.

+     * For example, on some devices the FOLDED state could mean that
+     * backward-facing cameras are covered by the fold, so FOLDED by itself implies
+     * BACK_COVERED. But other devices may support folding but not cover any cameras
+     * when folded, so for those FOLDED would not imply any of the other flags.
+     * Since these relationships are very device-specific, it is difficult to specify
+     * a comprehensive policy.  But as a recommendation, it is suggested that if a flag
+     * necessarily implies other flags are set as well, then those flags should be set.
+     * So even though FOLDED would be enough to infer BACK_COVERED on some devices, the
+     * BACK_COVERED flag should also be set for clarity.
+     *
+     * This method may be invoked by the HAL client at any time. It must not
+     * cause any active camera device sessions to be closed, but may dynamically
+     * change which physical camera a logical multi-camera is using for its
+     * active and future output.
+     *
+     * The method must be invoked by the HAL client at least once before the
+     * client calls ICameraDevice::open on any camera device interfaces listed
+     * by this provider, to establish the initial device state.

+     * The camera framework must call this method whenever it gets a
+     * cameraDeviceStatusChange callback adding a new camera device or removing
+     * a camera device known to it. This is so that the camera framework can get new combinations
+     * of camera ids that can stream concurrently, that might have potentially appeared.
+     *
+     * For each combination (and their subsets) of camera device ids returned by
+     * getConcurrentStreamingCameraIds(): If only the mandatory combinations can
+     * be supported concurrently by each device, then the resource costs must
+     * sum up to > 100 for the concurrent set, to ensure arbitration between
+     * camera applications work as expected. Only if resources are sufficient
+     * to run a set of cameras at full capability (maximally
+     * resource-consuming framerate and stream size settings available in the
+     * configuration settings exposed through camera metadata), should the sum
+     * of resource costs for the combination be <= 100.
+     *
+     * For guaranteed concurrent camera operation, the camera framework must call
+     * ICameraDevice.open() on all devices (intended for concurrent operation), before configuring
+     * any streams on them. This gives the camera HAL process an opportunity to potentially
+     * distribute hardware resources better before stream configuration.
+     *
+     * Due to potential hardware constraints around internal switching of physical camera devices,
+     * a device's complete ZOOM_RATIO_RANGE(if supported), may not apply during concurrent
+     * operation. If ZOOM_RATIO is supported, camera HALs must ensure ZOOM_RATIO_RANGE of
+     * [1.0, ANDROID_SCALER_AVAILABLE_MAX_DIGITAL_ZOOM] is supported by that device, during
+     * concurrent operation.
+     *
+     * A service specific error will be returned in the following case :

+     * @return a list of camera id combinations that support
+     *         concurrent stream configurations with the minimum guarantees
+     *         specified.

+     * The framework must not call this method with any combination of camera
+     * ids that is not a subset of the camera ids advertised by getConcurrentStreamingCameraIds of
+     * the same provider.
+     *
+     * Performance requirements:
+     * This call is expected to be significantly faster than stream
