+     * Set a device port of an external device into connected state.
+     *
+     * This method is used to inform the HAL module that an external device has
+     * been connected to a device port selected using the 'id' field of the
+     * input AudioPort parameter. This device port must have dynamic profiles
+     * (an empty list of profiles). This port is further referenced to as "port
+     * template" because it acts as a template for creating a new instance of a
+     * "connected" device port which gets returned from this method.
+     *
+     * The input AudioPort parameter may contain any additional data obtained by
+     * the system side from other subsystems. The nature of data depends on the
+     * type of the connection. For example, for point-to-multipoint external
+     * device connections, the input parameter may contain the address of the
+     * connected external device. Another example is EDID information for HDMI
+     * connections (ExtraAudioDescriptor), which can be provided by the HDMI-CEC
+     * HAL module.
+     *
+     * It is the responsibility of the HAL module to query audio profiles
+     * supported by the connected device and return them as part of the returned
+     * AudioPort instance. In the case when the HAL is unable to query the
+     * external device, an error must be thrown.
+     *
+     * Thus, the returned audio port instance is the result of combining the
+     * following information:
+     *  - a unique port ID generated by the HAL module;
+     *  - static information from the port template;
+     *  - list of audio profiles supported by the connected device;
+     *  - additional data from the input AudioPort parameter.
+     *
+     * The HAL module must also update the list of audio routes to include the
+     * ID of the instantiated connected device port. Normally, the connected
+     * port allows the same routing as the port template.
+     *
+     * Also see notes on 'ModuleDebug.simulateDeviceConnections'.
+     *
+     * The following protocol is used by HAL module client for handling
+     * connection of an external device:
+     *  1. Obtain the list of device ports and their IDs via 'getAudioPorts'
+     *     method. Select the appropriate port template using
+     *     AudioDeviceDescription ('ext.device' field of AudioPort).
+     *  2. Combine the ID of the port template with any additional data and call
+     *     'connectExternalDevice'. The HAL module returns a new instance of
+     *     AudioPort created using the rules explained above. Both
+     *     'getAudioPort' and 'getAudioPorts' methods will be returning the same
+     *     information for this port until disconnection.
+     *  3. Configure the connected port with one of supported profiles using
+     *     'setAudioPortConfig'.
+     *  4. Query the list of AudioRoutes for the new AudioPort using
+     *     'getAudioRoutesForAudioPort' or 'getAudioRoutes' methods.
+     *
+     * External devices are distinguished by the connection type and device
+     * address. Calling this method multiple times to inform about connection of
+     * the same external device without disconnecting it first is an error.
+     *
+     * The HAL module must perform validation of the input parameter and throw
+     * an error if it is lacking required information, for example, when no
+     * device address is specified for a point-to-multipoint external device
+     * connection.
+     *
+     * Handling of a disconnect is done in a reverse order:
+     *  1. Reset port configuration using the 'resetAudioPortConfig' method.
+     *  2. Release the connected device port by calling the 'disconnectExternalDevice'
+     *     method. This also removes the audio routes associated with this
+     *     device port.
+     *
+     * @return New instance of an audio port for the connected external device.
+     * @param templateIdAndAdditionalData Specifies port template ID and any
+     *                                    additional data.

+# AIDL VHAL libraries and reference implementation.
+---
+
+This directory stores the libraries useful for implementing vendor AIDL VHAL.
+This directory also stores a reference fake implementation for AIDL VHAL.
+
+## default_config
+
+Stores the default vehicle property configurations for reference vehicle HAL.
+Vendor implementation could copy this library but must update the configuration
+to meet their own requirements, e.g. enable or disable certain properties or
+update the initial value for certain properties.
+
+##	fake_impl
+
+Contains libraries used specifically for the fake reference VHAL implementation.
+These libraries are for test only and must not be directly used for vendor
+VHAL implementation.
+
+These libraries contain test-spcific logic and must not run directly on a real
+vehicle.
+
+## grpc
+
+Stores code for GRPC based VHAL implementation.
+
+## hardware
+
+Defines an interface `IVehicleHardware.h` which vendor must implement for
+vehicle-specific logic if they want to follow our reference VHAL design.
+
+## proto
+
+Stores Some protobuf files translated from AIDL VHAL interface types. These
+files are used in GRPC VHAL implementation.
+
+## utils
+
+Defines a library `VehicleHalUtils` which provides useful utility functions for
+VHAL implementation. Vendor VHAL could use this library.
+
+## vhal
+
+Defines a library `DefaultVehicleHal` which provides generic logic for all VHAL
+implementations (including reference VHAL). Vendor VHAL implementation could
+use this library, along with their own implementation for `IVehicleHardware`
+interface.
+
+Also defines a binary `android.hardware.automotive.vehicle@V1-default-service`
+which is the reference VHAL implementation. It implements `IVehicle.aidl`
+interface. It uses `DefaultVehicleHal`, along with `FakeVehicleHardware`
+(in fake_impl). It simulates the vehicle bus interaction by using an
+in-memory map. Meaning that all properties (except for some special ones) are
+just written into a hash map and read from a hash map without relying on any
+hardware. As a result, the reference implementation can run on emulator or
+any host environment.
+
+Vendor must not directly use the reference implementation for a real vehicle.

+# Fake reference AIDL VHAL implementation libraries
+---
+
+This directory stores libraries for implementing a fake reference AIDL VHAL.
+
+WARNING: All the libraries here are for TEST ONLY.
+
+## GeneratorHub
+
+Defines a library `FakeVehicleHalValueGenerators` that could generate fake
+vehicle property values for testing.
+
+## hardware
+
+Defines a fake implementation for device-specifc interface `IVehicleHardware`:
+`FakeVehicleHardware`. This implementation uses a in-memory map for storing
+property values and does not communicate with or depending on any specific
+vehicle bus.
+
+## obd2frame
+
+Defines a library `FakeObd2Frame` that generates fake OBD2 frame for OBD2
+properties.
+
+## userhal
+
+Defines a library `FakeUserHal` that emulates a real User HAL behavior by
+parsing debug commands.

+# Utility classes for VHAL implementation
+---
+
+This directory stores utility classes for VHAL implementation. Vendor
+implementation could use utility classes from `common` folder in their
+VHAL implementation.
+
+## common
+
+Defines common utility libraries.
+
+### ConcurrentQueue
+
+Provides a thread-safe concurrent queue object. Useful for adding object to
+a queue in one thread (usually binder thread) and handle the objects in a
+separate handler thread.
+
+### ParcelableUtils
+
+Provides functions to convert between a regular parcelable and a
+`LargeParcelabe`.
+
+A `LargeParcelable` is a parcelable that marshals the payload
+into a shared memory file if the payload is too large to pass across binder.
+It is used to pass large data across binder. Before sending the data, VHAL
+impl should convert a regular parcelabe to a `LargeParcelable`. After receving
+data, VHAL impl should convert a `LargeParcelable` back to regular parcelabe.
+
+### PendingRequestPool
+
+Defines A class for managing pending requests and automatically call timeout
+callback if the request timed-out.
+
+### PropertyUtils
+
+Defines some useful constants.
+
+### RecurrentTimer
+
+Defines a thread-safe recurrent timer that can call a function periodically.
+
+### VehicleHalTypes
+
+Provides a header file that includes many commonly used header files. Useful
+when you are using multiple types defined in VHAL interface.
+
+### VehicleObjectPool
+
+Defines a reusable in-memory pool for `VehiclePropValue`.
+
+### VehiclePropertyStore
+
+Defines an in-memory map for storing vehicle properties. Allows easier insert,
+delete and lookup.
+
+### VehicleUtils
+
+Defines many useful utility functions.
+
+## test
+
+Defines utility libraries for test only.

+on debuggable builds to allow devices to masquerade as alternative device
+types and for emulators.
+
+## Device Selection
+
+You can either run the FakeFaceEngine on a [real device](#actual-device) or a [virtual device/cuttlefish](#getting-started-on-a-virtual-device-cuttlefish). This document should
+help you to get started on either one.
+
+After setting up a device, go ahead and try out [enrolling](#enrolling) & [authenticating](#authenticating)
+
+### Getting started on a Virtual Device (cuttlefish)
+
+
+Note, I'm running this via a cloudtop virtual device.
+
+1. Setup cuttlefish on cloudtop, See [this](https://g3doc.corp.google.com/company/teams/android/teampages/acloud/getting_started.md?cl=head) for more details.
+2. acloud create --local-image
+3. Enter in the shell command to disable hidl
+
+```shell
+$ adb root
+$ adb shell settings put secure com.android.server.biometrics.AuthService.hidlDisabled 1
+$ adb reboot
+```
+4. You should now be able to do fake enrollments and authentications (as seen down below)
+
+### Actual Device
+
+1. Modify your real devices make file (I.E. vendor/google/products/{YOUR_DEVICE}.mk)
+2. Ensure that there is no other face HAL that is being included by the device
+3. Add the following
+```
+PRODUCT_COPY_FILES += \
+    frameworks/native/data/etc/android.hardware.biometrics.face.xml:$(TARGET_COPY_OUT_PRODUCT)/etc/permissions/android.hardware.biometrics.face.xml
+
+PRODUCT_PACKAGES += \
+    android.hardware.biometrics.face-service.example \
+
+```
+4. Now build and flash m -j120 && flash
+5. Run the following commands
+
+```shell
+# This is a temporary workaround
+$ adb root
+$ adb shell setprop persist.vendor.face.virtual.type RGB
+$ adb shell setprop persist.vendor.face.virtual.strength strong
+$ adb shell locksettings set-pin 0000
+$ adb reboot
+```
+
+## Enrolling
+
+```shell
+# authenticar_id,bucket_id:duration:(true|false)....
+$ adb shell setprop vendor.face.virtual.next_enrollment 1,0:500:true,5:250:true,10:150:true,15:500:true
+$ adb shell am start -n com.android.settings/.biometrics.face.FaceEnrollIntroduction
+# If you would like to get rid of the enrollment, run the follwoing command
+$ adb shell setprop persist.vendor.face.virtual.enrollments \"\"
+```
+
+## Authenticating
+
+```shell
+# If enrollment hasn't been setup
+$ adb shell setprop persist.vendor.face.virtual.enrollments 1
+$ adb shell cmd face sync
+# After enrollment has been setup
+$ adb shell setprop vendor.face.virtual.operation_authenticate_duration 800
+$ adb shell setprop vendor.face.virtual.enrollment_hit 1
+# Power button press to simulate auth
+$ adb shell input keyevent 26
+```

+# Virtual Fingerprint HAL
+
+This is a virtual HAL implementation that is backed by system properties instead
+of actual hardware. It's intended for testing and UI development on debuggable
+builds to allow devices to masquerade as alternative device types and for
+emulators.
+
+## Supported Devices
+
+This HAL can be used on emulators, like cuttlefish, or on real devices. Add the
+following to your device's `.mk` file to include it:
+
+```
+PRODUCT_PACKAGES_DEBUG += android.hardware.biometrics.fingerprint-service.example
+```
+
+The virtual HAL will be ignored if a real HAL is also installed on the target
+device. Set the `biometric_virtual_enabled` settings and reboot the device to
+switch to the virtual HAL. Unset it and reboot again to switch back.
+
+## Getting Started
+
+First, set the type of sensor the device should use, enable the virtual
+extensions in the framework, and reboot.
+
+This doesn't work with HIDL and you typically need to have a PIN or password set
+for things to work correctly, so this is a good time to set those too.
+
+```shell
+$ adb root
+$ adb shell settings put secure biometric_virtual_enabled 1
+$ adb shell setprop persist.vendor.fingerprint.virtual.type rear
+$ adb shell locksettings set-pin 0000
+$ adb shell settings put secure com.android.server.biometrics.AuthService.hidlDisabled 1
+$ adb reboot
+```
+
+### Enrollments
+
+Next, setup enrollments on the device. This can either be done through the UI,
+or via adb.
+
+#### UI Enrollment
+
+1. Tee up the results of the enrollment before starting the process:
+
+      ```shell
+      $ adb shell setprop vendor.fingerprint.virtual.next_enrollment 1:100,100,100:true
+      ```
+2. Navigate to `Settings -> Security -> Fingerprint Unlock` and follow the
+   prompts.
+3. Verify the enrollments in the UI:
+
+      ```shell
+      $ adb shell getprop persist.vendor.fingerprint.virtual.enrollments
+      ```
+
+#### Direct Enrollment
+
+To set enrollment directly without the UI:
+
+```shell
+$ adb root
+$ adb shell setprop persist.vendor.fingerprint.virtual.enrollments 1
+$ adb shell cmd fingerprint sync
+```
+
+**Note: You may need to do this twice.** The templates are checked as part of
+some lazy operations, like user switching and startup, which can cause the
+framework to delete the enrollments before the sync operation runs. Until this
+is fixed, just run the commands twice as a workaround.
+
+### Authenticate
+
+To authenticate successfully set the enrolled id that should succeed. Unset it
+or change the value to make authenticate operations fail:
+
+````shell
+$ adb shell setprop vendor.fingerprint.virtual.enrollment_hit 1
+````
+
+### View HAL State
+
+To view all the properties of the HAL (see `fingerprint.sysprop` for the API):
+
+```shell
+$ adb shell getprop | grep vendor.fingerprint.virtual
+```
