+     * The configArray is set as follows:

+     * 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:
+     *
+     * int32[0]: -108  // request id
+     * int32[1]: 4     // messageType = SwitchUserMessageType::VEHICLE_REQUEST
+     * int32[2]: 11    // Android user id
+     *
+     * If the request succeeded and Android has 3 users (0, 10, 11), the response would be:
+     *
+     * int32[0]: -108 // request id
+     * int32[1]:  5   // messageType = SwitchUserMessageType::ANDROID_POST_SWITCH
+     * int32[2]:  11  // target user id
+     * int32[3]:  0   // target user id flags (none)
+     * int32[4]:  11  // current user
+     * int32[5]:  0   // current user flags (none)
+     * int32[6]:  3   // number of users
+     * int32[7]:  0   // 1st user (user 0)
+     * int32[8]:  0   // 1st user flags (none)
+     * int32[9]:  10  // 2nd user (user 10)
+     * int32[10]: 4   // 2nd user flags (none)
+     * int32[11]: 11  // 3rd user (user 11)
+     * int32[12]: 3   // 3rd user flags (none)
+     *
+     * Notice that both the current and target user ids are the same - if the request failed, then
+     * they would be different (i.e, target user would be 11, but current user would still be 10).
+     *
+     * 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.

+     * user-related functions described on INITIAL_USER_INFO.
+     *
+     * To query the association, the Android system gets the property, passing a VehiclePropValue
+     * containing the types of associations are being queried, as defined by
+     * UserIdentificationGetRequest. The HAL must return right away, returning a VehiclePropValue
+     * with a UserIdentificationResponse. Notice that user identification should have already
+     * happened while system is booting up and the VHAL implementation should only return the
+     * already identified association (like the key FOB used to unlock the car), instead of starting
+     * a new association from the get call.
+     *
+     * To associate types, the Android system sets the property, passing a VehiclePropValue
+     * containing the types and values of associations being set, as defined by the
+     * UserIdentificationSetRequest. The HAL will then use a property change event (whose
+     * 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[3]: 2   (1st value: UserIdentificationAssociationValue::ASSOCIATED_CURRENT_USER)

+     * 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[3]: 1   (number of associations being set)
+     * int32[4]: 101 (1st type: UserIdentificationAssociationType::CUSTOM_1)
+     * int32[5]: 1   (1st value: UserIdentificationAssociationSetValue::ASSOCIATE_CURRENT_USER)
+     *
+     * If the request succeeded, the response would be simply:
+     *
+     * int32[0]: 43  // request id
+     * int32[1]: 1   (number of associations in the response)
+     * int32[2]: 101 (1st type: UserIdentificationAssociationType::CUSTOM_1)
+     * int32[3]: 1   (1st value: UserIdentificationAssociationValue::ASSOCIATED_CURRENT_USER)
+     *
+     * Notice that the set request adds associations, but doesn't remove the existing ones. In the
+     * example above, the end state would be 2 associations (FOB and CUSTOM_1). If we wanted to
+     * associate the user with just CUSTOM_1 but not FOB, then the request should have been:
+     *

+// 2). this is a 'current' file. If you make a backwards compatible change to
+//     the interface (from the latest frozen version), the build system will

+//
+// You must not make a backward incompatible change to any AIDL file built
+// with the aidl_interface module type with versions property set. The module
+// type is used to build AIDL files in a way that they can be used across
+// independently updatable components of the system. If a device is shipped
+// with such a backward incompatible change, it has a high risk of breaking
+// later when a module using the interface is updated, e.g., Mainline modules.

+/**
+ * This is a quick-and-dirty sound trigger HAL console mock.
+ *
+ * It would only work on userdebug builds.
+ *
+ * When this app is started, it will initially:
+ * - Register a ISoundTriggerHw HAL with an instance name "mock".
+ * - Set a sysprop that tells SoundTriggerMiddlewareService to try to connect to the mock instance
+ * rather than the default one.
+ * - Reboot the real (default) HAL.
+ *
+ * In response to that, SoundTriggerMiddlewareService is going to connect to the mock HAL and resume
+ * normal operation.
+ *
+ * Our mock HAL will print to stdout every call it receives as well as expose a basic set of
+ * operations for sending event callbacks to the client. This allows us to simulate the frameworks
+ * behavior in response to different HAL behaviors.

+/**
+ * SoundTrigger HAL interface. Used for hardware recognition of hotwords
+ * and other sounds.
+ *
+ * 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).

+ * This is a quick-and-dirty sound trigger HAL console mock.
+ *
+ * It would only work on userdebug builds.
+ *
+ * When this app is started, it will initially:
+ * - Register a ISoundTriggerHw HAL with an instance name "mock".
+ * - Set a sysprop that tells SoundTriggerMiddlewareService to try to connect to the mock instance
+ * rather than the default one.
+ * - Reboot the real (default) HAL.
+ *
+ * In response to that, SoundTriggerMiddlewareService is going to connect to the mock HAL and resume
+ * normal operation.
+ *
+ * Our mock HAL will print to stdout every call it receives as well as expose a basic set of
+ * operations for sending event callbacks to the client. This allows us to simulate the frameworks
+ * behavior in response to different HAL behaviors.
