+     * Additional rules for mapping a zoned HVAC property (except
+     * HVAC_MAX_DEFROST_ON) to AreaIDs:
+     *  - Every seat in VehicleAreaSeat that is available in the car, must be
+     *    part of an AreaID in the AreaID array.
+     *
+     * Example 1: A car has two front seats (ROW_1_LEFT, ROW_1_RIGHT) and three
+     *  back seats (ROW_2_LEFT, ROW_2_CENTER, ROW_2_RIGHT). There are two
+     *  temperature control units -- driver side and passenger side.
+     *   - A valid mapping set of AreaIDs for HVAC_TEMPERATURE_SET would be a
+     *     two element array:
+     *      - ROW_1_LEFT  | ROW_2_LEFT
+     *      - ROW_1_RIGHT | ROW_2_CENTER | ROW_2_RIGHT
+     *   - An alternative mapping for the same hardware configuration would be:
+     *      - ROW_1_LEFT  | ROW_2_CENTER | ROW_2_LEFT
+     *      - ROW_1_RIGHT | ROW_2_RIGHT
+     *  The temperature controllers are assigned to the seats which they
+     *  "most influence", but every seat must be included exactly once. The
+     *  assignment of the center rear seat to the left or right AreaID may seem
+     *  arbitrary, but the inclusion of every seat in exactly one AreaID ensures
+     *  that the seats in the car are all expressed and that a "reasonable" way
+     *  to affect each seat is available.
+     *
+     * Example 2: A car has three seat rows with two seats in the front row (ROW_1_LEFT,
+     *  ROW_1_RIGHT) and three seats in the second (ROW_2_LEFT, ROW_2_CENTER,
+     *  ROW_2_RIGHT) and third rows (ROW_3_LEFT, ROW_3_CENTER, ROW_3_RIGHT). There
+     *  are three temperature control units -- driver side, passenger side, and rear.
+     *   - A reasonable way to map HVAC_TEMPERATURE_SET to AreaIDs is a three
+     *     element array:
+     *     - ROW_1_LEFT
+     *     - ROW_1_RIGHT

+     * An application calls set(VehiclePropValue propValue) with the requested value and unit for
+     * the value. OEMs need to return the suggested values in floatValues[2] and floatValues[3] by
+     * onPropertyEvent() callbacks.
+     *
+     * For example, when a user uses the voice assistant to set HVAC temperature to 66.2 in
+     * Fahrenheit.
+     * First, an application will set this property with the value
+     * [66.2, (float)VehicleUnit:FAHRENHEIT,0,0].
+     * If OEMs suggest to set 19.0 in Celsius or 66.5 in Fahrenheit for user's request, then VHAL
+     * must generate a callback with property value
+     * [66.2, (float)VehicleUnit:FAHRENHEIT, 19.0, 66.5]. After the voice assistant gets the
+     * callback, it will inform the user and set HVAC temperature to the suggested value.
+     *
+     * Another example, an application receives 21 Celsius as the current temperature value by
+     * querying HVC_TEMPERATURE_SET. But the application wants to know what value is displayed on
+     * the car's UI in Fahrenheit.
+     * For this, the application sets the property to [21, (float)VehicleUnit:CELSIUS, 0, 0]. If
+     * the suggested value by the OEM for 21 Celsius is 70 Fahrenheit, then VHAL must generate a
+     * callback with property value [21, (float)VehicleUnit:CELSIUS, 21.0, 70.0].
+     * In this case, the application can know that the value is 70.0 Fahrenheit in the car’s UI.

+     * 1.LEGACY_ANDROID_SWITCH
+     * -----------------------
+     *
+     * Called by the Android System to indicate the Android user is about to change, when the change
+     * request was made in a way that is not integrated with the HAL (for example, through
+     * adb shell am switch-user).
+     *
+     * The HAL can switch its internal user once it receives this request, but it doesn't need to
+     * reply back to the Android System. If its internal user cannot be changed for some reason,
+     * then it must wait for the SWITCH_USER(type=ANDROID_POST_SWITCH) call to recover
+     * (for example, it could issue a SWITCH_USER(type=VEHICLE_REQUEST) to switch back to
+     * the previous user), but ideally it should never fail (as switching back could result in a
+     * confusing experience for the end user).
+     *
+     * For example, if the system have users (0, 10, 11) and it's switching from 0 to 11 (where none
+     * of them have any special flag), the request would be:
+     *
+     * int32[0]:  42  // request id
+     * int32[1]:  1   // SwitchUserMessageType::LEGACY_ANDROID_SWITCH
+     * int32[2]:  11  // target user id
+     * int32[3]:  0   // target user flags (none)
+     * int32[4]:  10  // current user
+     * int32[5]:  0   // current user flags (none)
+     * int32[6]:  3   // number of users
+     * int32[7]:  0   // user #0 (Android user id 0)
+     * int32[8]:  0   // flags of user #0 (none)
+     * int32[9]:  10  // user #1 (Android user id 10)
+     * int32[10]: 0   // flags of user #1 (none)
+     * int32[11]: 11  // user #2 (Android user id 11)
+     * int32[12]: 0   // flags of user #2 (none)
+     *
+     * 2.ANDROID_SWITCH
+     * ----------------
+     * Called by the Android System to indicate the Android user is about to change, but Android
+     * will wait for the HAL's response (up to some time) before proceeding.
+     *
+     * The HAL must switch its internal user once it receives this request, then respond back to
+     * Android with a SWITCH_USER(type=VEHICLE_RESPONSE) indicating whether its internal
+     * user was switched or not (through the SwitchUserStatus enum).
+     *
+     * For example, if Android has users (0, 10, 11) and it's switching from 10 to 11 (where
+     * none of them have any special flag), the request would be:
+     *
+     * int32[0]:  42  // request id
+     * int32[1]:  2   // SwitchUserMessageType::ANDROID_SWITCH
+     * int32[2]:  11  // target user id
+     * int32[3]:  0   // target user flags (none)
+     * int32[4]:  10  // current user
+     * int32[5]:  0   // current user flags (none)
+     * int32[6]:  3   // number of users
+     * int32[7]:  0   // 1st user (user 0)
+     * int32[8]:  1   // 1st user flags (SYSTEM)
+     * int32[9]:  10  // 2nd user (user 10)
+     * int32[10]: 0   // 2nd user flags (none)
+     * int32[11]: 11  // 3rd user (user 11)
+     * int32[12]: 0   // 3rd user flags (none)
+     *
+     * If the request succeeded, the HAL must update the property with:
+     *
+     * int32[0]: 42  // request id
+     * int32[1]: 3   // messageType = SwitchUserMessageType::VEHICLE_RESPONSE
+     * int32[2]: 1   // status = SwitchUserStatus::SUCCESS
+     *
+     * But if it failed, the response would be something like:
+     *
+     * int32[0]: 42   // request id
+     * int32[1]: 3    // messageType = SwitchUserMessageType::VEHICLE_RESPONSE
+     * int32[2]: 2    // status = SwitchUserStatus::FAILURE
+     * string: "108-D'OH!" // OEM-specific error message
+     *
+     * 3.VEHICLE_RESPONSE
+     * ------------------
+     * Called by the HAL to indicate whether a request of type ANDROID_SWITCH should proceed or
+     * abort - see the ANDROID_SWITCH section above for more info.
+     *
+     * 4.VEHICLE_REQUEST
+     * ------------------
+     * Called by the HAL to request that the current foreground Android user is switched.
+     *
+     * This is useful in situations where Android started as one user, but the vehicle identified
+     * the driver as another user. For example, user A unlocked the car using the key fob of user B;
+     * the INITIAL_USER_INFO request returned user B, but then a face recognition subsubsystem
+     * identified the user as A.
+     *
+     * The HAL makes this request by a property change event (passing a negative request id), and
+     * the Android system will response by issue an ANDROID_POST_SWITCH call which the same
+     * request id.
+     *
+     * For example, if the current foreground Android user is 10 and the HAL asked it to switch to
+     * 11, the request would be:

+     * 5.ANDROID_POST_SWITCH
+     * ---------------------
+     * Called by the Android System after a request to switch a user was made.
+     *
+     * This property is called after switch requests of any type (i.e., LEGACY_ANDROID_SWITCH,
+     * ANDROID_SWITCH, or VEHICLE_REQUEST) and can be used to determine if the request succeeded or
+     * failed:
+     *
+     * 1. When it succeeded, it's called when the Android user is in the unlocked state and the
+     *    value of the current and target users ids in the response are the same. This would be
+     *    equivalent to receiving an Intent.ACTION_USER_UNLOCKED in an Android app.
+     * 2. When it failed it's called right away and the value of the current and target users ids
+     *    in the response are different (as the current user didn't change to the target).
+     * 3. If a new switch request is made before the HAL responded to the previous one or before
+     *    the user was unlocked, then the ANDROID_POST_SWITCH request is not made. For example,
+     *    the driver could accidentally switch to the wrong user which has lock credentials, then
+     *    switch to the right one before entering the credentials.
+     *
+     * The HAL can update its internal state once it receives this request, but it doesn't need to
+     * reply back to the Android System.
+     *
+     * Request: the first N values as defined by INITIAL_USER_INFO (where the request-specific
+     * value at index 1 is SwitchUserMessageType::ANDROID_POST_SWITCH), then 2 more values for the
+     * target user id (i.e., the Android user id that was requested to be switched to) and its flags
+     * (as defined by  UserFlags).
+     *
+     * Response: none.
+     *
+     * Example: see VEHICLE_REQUEST section above.

+     *
+     * To query the association, the Android system gets the property, passing a VehiclePropValue
+     * containing the types of associations are being queried, as defined by

+     * already identified association (like the key FOB used to unlock the car), instead of starting

+     * To associate types, the Android system sets the property, passing a VehiclePropValue

+     * VehiclePropValue is defined by UserIdentificationResponse) indicating the current status of
+     * the types after the request.
+     *
+     * For example, to query if the current user (10) is associated with the FOB that unlocked the
+     * car and a custom mechanism provided by the OEM, the request would be:
+     *
+     * int32[0]: 42  // request id
+     * int32[1]: 10  (Android user id)
+     * int32[2]: 0   (Android user flags)
+     * int32[3]: 2   (number of types queried)
+     * int32[4]: 1   (1st type queried, UserIdentificationAssociationType::KEY_FOB)
+     * int32[5]: 101 (2nd type queried, UserIdentificationAssociationType::CUSTOM_1)
+     *
+     * If the user is associated with the FOB but not with the custom mechanism, the response would
+     * be:
+     *
+     * int32[0]: 42  // request id
+     * int32[1]: 2   (number of associations in the response)
+     * int32[2]: 1   (1st type: UserIdentificationAssociationType::KEY_FOB)

+     * int32[5]: 4   (2nd value: UserIdentificationAssociationValue::NOT_ASSOCIATED_ANY_USER)
+     *
+     * Then to associate the user with the custom mechanism, a set request would be made:
+     *
+     * int32[0]: 43  // request id
+     * int32[1]: 10  (Android user id)
+     * int32[2]: 0   (Android user flags)

+     * int32[5]: 1   (1st value: UserIdentificationAssociationSetValue::ASSOCIATE_CURRENT_USER)
+     *
+     * If the request succeeded, the response would be simply:

+/**
+ * SoundTrigger HAL interface. Used for hardware recognition of hotwords
+ * and other sounds.
+ *
+ * Important notes about the threading model:
+ * ==========================================
+ * Both this interface and the corresponding callback interface use a synchronized calling
+ * convention. This model comes with some advantages, but also with some risks of deadlocks if the
+ * implementation does not handle this correctly. Please consider the following:
+ * - After stopRecognition() returns no more recognition events for that model may be sent. This
+ *   implies that any queues holding such events must be flushed before the call returns and that
+ *   may imply that callback from the HAL to the client are done while stopRecognition() is blocked.
+ *   This is OK, and supported by the framework.
+ * - Similarly, the same relationship applies between unloadModel() and subsequent callbacks to
+ *   modelUnloaded().
+ * - Other than these two cases, calls into the HAL *MAY NOT* block on callbacks from the HAL, or
+ *   else deadlock conditions may result, which may be handled by rebooting of the HAL process and
+ *   cause service outages.
+ *
+ * Similarly, it is expected that a single call to startRecognition() generates at most one event
+ * (the model automatically becomes stopped when the event occurs, until explicitly started again)
+ * and that after a modelUnloaded() event no more events would be sent regarding the model.
+ * Note that a getModelState() call may generate a recognition event, but this event DOES NOT modify
+ * the model state - the model remains started.
+ *
+ * The HAL is expected to correctly handle a stopRecognition() call even after it sent an event
+ * indicating that recognition is stopped and an unloadModel() call even after it sent an event
+ * indicating that it has been unloaded. This is required in order to prevent race conditions
+ * between these calls. This also implies that model handles should generally not be reused until
+ * explicitly unloaded. To avoid the rare possibility of running out of handles, the framework will
+ * call unloadModel() on models that have been preemptively unloaded by the HAL.
+ *
+ * Due to the asynchronous nature of recognition events and preemptive model unloading, the HAL must
+ * correctly handle requests that would have been valid before an event has been delivered, but
+ * became moot as result of the event. Namely:
+ * - stopRecognition() may be called on a model that has already delivered an event and became
+ *   inactive as a result. The HAL must return a successful return code in this case.
+ * - Furthermore, if a model is preemptively unloaded after it triggers (typically, this would
+ *   happen when it is first aborted and immediately preemptively unloaded), stopRecognition() may
+ *   be called on it. The HAL must return a successful return code in this case.
+ * - startRecognition() may be called on a model that has been preemptively unloaded. In this case,
+ *   the HAL must return -EBUSY to indicate that the operation is temporarily unsuccessful.
+ * - unloadSoundModel() may be called on a model that has been preemptively unloaded. The HAL must
+ *   return a successful return code in this case.
+ *
+ * Important notes about resource constraints and concurrency
+ * =========================================================
+ * Up until this version, the framework would enforce concurrency constraints expressed by the
+ * Properties presented by the soundtrigger instance. These include constraints on the maximum
+ * amount of models that can be loaded at the same time and on running recognition while capturing
+ * from the microphone.
+ * This version changes the approach for how these constraints are modeled, both offering the HAL
+ * implementation more flexibility and simplifying the framework's job in enforcing these
+ * limitations. Note that there is no change for how the framework behaves with earlier versions,
+ * everything described below only applies to this version and onward.
+ * The way this is achieved is as following:
+ * - The framework will no longer enforce constraints on concurrent loading of models, as expressed
+ *   in the Properties.maxSoundModels field (this property is merely a hint at this point and may be
+ *   deprecated in the future.
+ * - The framework will no longer enforce constraints on concurrency of audio recording and
+ *   soundtrigger operation, as expressed in the Properties.concurrentCapture field (this property
+ *   is merely a hint at this point and may be deprecated in the future).
+ * - The framework will no longer enforce constraints on concurrent loading of models, as expressed
+ *   in the Properties (these properties are merely hints at this point and may be deprecated in the
+ *   future.
+ * - The HAL implementation is free to reject starting of any model at any time by having the
+ *   respective start*() method return -EBUSY.
+ * - The HAL implementation is free to reject loading of any model at any time by having the
+ *   respective load*() method return -EBUSY.
+ * - The HAL implementation is free to preemptively stop a previously started model at its own
+ *   discretion (for example, if a higher priority use-case which cannot coexist with detection
+ *   has been requested). The HAL must notify the framework of the preemption by sending a
+ *   recognition event with an `ABORT` status. The implementation must NOT attempt to restart the
+ *   recognition automatically when conditions change.
+ * - The HAL implementation is free to preemptively unload a previously loaded model at its own
+ *   discretion (for example, if a higher-priority model is being loaded and the two cannot
+ *   coexist). When doing so, it must first abort the detection if active (as per above) and then
+ *   notify the framework of the unload using the newly added modelUnloaded callback.
+ * - When conditions change, such that a model that couldn't previously load or start or that had
+ *   previously been preemptively stopped or unloaded, the HAL must notify the framework via the
+ *   newly added tryAgain() callback. This callback is not a guarantee that any operation would now
+ *   succeed, but merely a hint that retrying something that had previously failed, now MAY succeed.
+ *   Until this callback arrives, the framework may assume that any operation that had previously
+ *   failed or aborted would still fail if retried, so the implementation should not forget to
+ *   deliver it. There are no guarantees regarding how the framework may respond to this event and
+ *   the order in which it may choose to reload/restart its models. Typically, as result of this
+ *   event the framework will make a single attempt per model to bring this model to its desired
+ *   state (loaded, started).

+ *
+ * Basic usage:
+ * ============
+ * ISoundTriggerHw supports the ability to have one of more  detection sessions running at a given
+ * time, and listening to acoustic events. The basic flow of setting up such a session is:
+ * - Load a model using loadSoundModel() or loadPhraseSoundModel(). The provided model object would
+ *   indicate the (implementation-specific) detection algorithm (engine) to use, as well as any
+ *   parameters applicable for this agorithm. Upon success, those methods would return a handle
+ *   which will be used to reference this model in subsequent calls.
+ * - Once the model had been successfully loaded, detection can begin by calling startRecognition().
+ * - Recognition will continue running in the background until one of the following events occurs:
+ *   - stopRecognition() has been called on this model.
+ *   - A detection has occurred.
+ *   - Detection was aborted, typically for resource constraints, for example, when a higher-
+ *     priority use-case has been initiated.
+ * - In the latter two cases, a recognition event will be sent via a the callback interface that was
+ *   registered by the client upon loading. In either case, after any of these events occur, the
+ *   detection becomes inactive and no more recognition callbacks are allowed.
+ * - The same model maybe started again at a later time, and this process may repeat as many times
+ *   as needed.
+ * - Finally, an inactive model that is no longer needed may be unloaded via unloadModel().
+ *
+ * Important notes about the threading model:
+ * ==========================================
+ * Both this interface and the corresponding callback interface use a synchronous calling
+ * convention. This model comes with some advantages, but also with some risks of deadlocks if the
+ * implementation does not handle this correctly. Please consider the following:
+ * - After stopRecognition() returns, no more recognition events for that model may be sent. This
+ *   implies that any queues holding such events must be flushed before the call returns and that
+ *   may imply that callback from the HAL to the client are done while stopRecognition() is blocked.
+ *   This is OK, and supported by the framework.
+ * - Similarly, the same relationship applies between unloadModel() and subsequent callbacks to
+ *   modelUnloaded().
+ * - Other than these two cases, calls into the HAL *MAY NOT* block on callbacks from the HAL, or
+ *   else deadlock conditions may result, which may be handled by rebooting of the HAL process and
+ *   cause service outages.
+ *
+ * Due to the asynchronous nature of recognition events and preemptive model unloading, the HAL must
+ * correctly handle requests that would have been valid before an event has been delivered, but
+ * became moot as result of the event. Namely:
+ * - stopRecognition() may be called on a model that has already delivered an event and became
+ *   inactive as a result. The HAL must return a successful return code in this case.
+ * - Furthermore, if a model is preemptively unloaded after it triggers (typically, this would
+ *   happen when it is first aborted and immediately preemptively unloaded), stopRecognition() may
+ *   be called on it. The HAL must return successfully in this case.
+ * - startRecognition() may be called on a model that has been preemptively unloaded. In this case,
+ *   the HAL must signal a ServiceSpecificException(RESOURCE_CONTENTION) to indicate that the
+ *   operation is temporarily unsuccessful.
+ * - unloadSoundModel() may be called on a model that has been preemptively unloaded. The HAL must
+ *   return a successful return code in this case. This also implies that model handles should
+ *   generally not be reused until explicitly unloaded. To avoid the rare possibility of running out
+ *   of handles, the framework may call unloadModel() on models that have been preemptively unloaded
+ *   by the HAL.
+ *
+ * Important notes about resource constraints and concurrency
+ * =========================================================
+ * Up until this version, the framework would enforce concurrency constraints expressed by the
+ * Properties presented by the soundtrigger instance. These include constraints on the maximum
+ * amount of models that can be loaded at the same time and on running recognition while capturing
+ * from the microphone.
+ * This version changes the approach for how these constraints are modeled, both offering the HAL
+ * implementation more flexibility and simplifying the framework's job in enforcing these
+ * limitations. Note that there is no change for how the framework behaves with earlier versions,
+ * everything described below only applies to this version and onward.
+ * The way this is achieved is as following:
+ * - The framework will no longer enforce constraints on concurrent loading of models, as expressed
+ *   in the Properties.maxSoundModels field (this property is merely a hint at this point and may be
+ *   deprecated in the future), or any other implicit constraints.
+ * - The framework will no longer enforce constraints on concurrency of audio recording and
+ *   soundtrigger operation, as expressed in the Properties.concurrentCapture field (this property
+ *   is merely a hint at this point and may be deprecated in the future).
+ * - The HAL implementation is free to reject loading of any model at any time by having the
+ *   respective load*() method signal a ServiceSpecificException(RESOURCE_CONTENTION).
+ * - The HAL implementation is free to reject starting of any model at any time by having the
+ *   respective start*() method signal a ServiceSpecificException(RESOURCE_CONTENTION).
+ * - The HAL implementation is free to preemptively stop a previously started model at its own
+ *   discretion (for example, if a higher priority use-case which cannot coexist with detection
+ *   has been requested). The HAL must notify the framework of the preemption by sending a
+ *   recognition event with an `ABORTED` status. The implementation must NOT attempt to restart the
+ *   recognition automatically when conditions change.
+ * - The HAL implementation is free to preemptively unload a previously loaded model at its own
+ *   discretion (for example, if a higher-priority model is being loaded and the two cannot
+ *   coexist). When doing so, it must first abort the detection if active (as per above) and then
+ *   notify the framework of the unload using the modelUnloaded() callback.
+ * - When conditions change, such that a model that couldn't previously load or start or that had
+ *   previously been preemptively stopped or unloaded, the HAL must notify the framework via the
+ *   newly added onResourcesAvailable() callback. This callback is not a guarantee that any
+ *   operation would now succeed, but merely a hint that retrying something that had previously
+ *   failed, now MAY succeed. Until this callback is invoked, the client may assume that any
+ *   operation that had previously failed or aborted would still fail if retried, so the
+ *   implementation should not forget to deliver it.
+ *   There are no guarantees regarding how the framework may respond to this event and the order in
+ *   which it may choose to reload/restart its models. Typically, as result of this event the
+ *   framework will make a single attempt per model to bring this model to its desired state
+ *   (loaded, started).
