-/**
- * Supports Fast Pair pairing with certain Bluetooth headphones, Auto, etc.
- *
- * <p>Based on https://developers.google.com/nearby/fast-pair/spec, the pairing is constructed by
- * both BLE and BREDR connections. Example state transitions for Fast Pair 2, ie a pairing key is
- * included in the request (note: timeouts and retries are governed by flags, may change):
- *
- * <pre>
- * {@code
- *   Connect GATT
- *     A) Success -> Handshake
- *     B) Failure (3s timeout) -> Retry 2x -> end
- *
- *   Handshake
- *     A) Generate a shared secret with the headset (either using anti-spoofing key or account key)
- *       1) Account key is used directly as the key
- *       2) Anti-spoofing key is used by combining out private key with the headset's public and
- *          sending our public to the headset to combine with their private to generate a shared
- *          key. Sending our public key to headset takes ~3s.
- *     B) Write an encrypted packet to the headset containing their BLE address for verification
- *        that both sides have the same key (headset decodes this packet and checks it against their
- *        own address) (~250ms).
- *     C) Receive a response from the headset containing their public address (~250ms).
- *
- *   Discovery (for devices < Oreo)
- *     A) Success -> Create Bond
- *     B) Failure (10s timeout) -> Sleep 1s, Retry 3x -> end
- *
- *   Connect to device
- *     A) If already bonded
- *       1) Attempt directly connecting to supported profiles (A2DP, etc)
- *         a) Success -> Write Account Key
- *         b) Failure (15s timeout, usually fails within a ~2s) -> Remove bond (~1s) -> Create bond
- *     B) If not already bonded
- *       1) Create bond
- *         a) Success -> Connect profile
- *         b) Failure (15s timeout) -> Retry 2x -> end
- *       2) Connect profile
- *         a) Success -> Write account key
- *         b) Failure -> Retry -> end
- *
- *   Write account key
- *     A) Callback that pairing succeeded
- *     B) Disconnect GATT
- *     C) Reconnect GATT for secure connection
- *     D) Write account key (~3s)

-/**
- * This is exported from frameworks ServiceWatcher.
- * A ServiceMonitor is responsible for continuously maintaining an active binding to a service
- * selected by it's {@link ServiceProvider}. The {@link ServiceProvider} may change the service it
- * selects over time, and the currently bound service may crash, restart, have a user change, have
- * changes made to its package, and so on and so forth. The ServiceMonitor is responsible for
- * maintaining the binding across all these changes.
- *
- * <p>Clients may invoke {@link BinderOperation}s on the ServiceMonitor, and it will make a best
- * effort to run these on the currently bound service, but individual operations may fail (if there
- * is no service currently bound for instance). In order to help clients maintain the correct state,
- * clients may supply a {@link ServiceListener}, which is informed when the ServiceMonitor connects
- * and disconnects from a service. This allows clients to bring a bound service back into a known
- * state on connection, and then run binder operations from there. In order to help clients
- * accomplish this, ServiceMonitor guarantees that {@link BinderOperation}s and the
- * {@link ServiceListener} will always be run on the same thread, so that strong ordering guarantees
- * can be established between them.
- *
- * There is never any guarantee of whether a ServiceMonitor is currently connected to a service, and
- * whether any particular {@link BinderOperation} will succeed. Clients must ensure they do not rely
- * on this, and instead use {@link ServiceListener} notifications as necessary to recover from

-# Nearby Mainline Fast Pair end-to-end tests
-
-This document refers to the Mainline Fast Pair project source code in the
-packages/modules/Connectivity/nearby. This is not an officially supported Google
-product.
-
-## About the Fast Pair Project
-
-The Connectivity Nearby mainline module is created in the Android T to host
-Better Together related functionality. Fast Pair is one of the main
-functionalities to provide seamless onboarding and integrated experiences for
-peripheral devices (for example, headsets like Google Pixel Buds) in the Nearby
-component.
-
-## Fully automated test
-
-### Prerequisites
-
-The fully automated end-to-end (e2e) tests are host-driven tests (which means
-test logics are in the host test scripts) using Mobly runner in Python. The two
-phones are installed with the test snippet
-`NearbyMultiDevicesClientsSnippets.apk` in the test time to let the host scripts
-control both sides for testing. Here's the overview of the test environment.
-
-Workstation (runs Python test scripts and controls Android devices through USB
-ADB) \
-├── Phone 1: As Fast Pair seeker role, to scan, pair Fast Pair devices nearby \
-└── Phone 2: As Fast Pair provider role, to simulate a Fast Pair device (for
-example, a Bluetooth headset)
-
-Note: These two phones need to be physically within 0.3 m of each other.
-
-### Prepare Phone 1 (Fast Pair seeker role)
-
-This is the phone to scan/pair Fast Pair devices nearby using the Nearby
-Mainline module. Test it by flashing with the Android T ROM.
-
-### Prepare Phone 2 (Fast Pair provider role)
-
-This is the phone to simulate a Fast Pair device (for example, a Bluetooth
-headset). Flash it with a customized ROM with the following changes:
-
-*   Adjust Bluetooth profile configurations. \
-    The Fast Pair provider simulator is an opposite role to the seeker. It needs
-    to enable/disable the following Bluetooth profile:
-    *   Disable A2DP source (bluetooth.profile.a2dp.source.enabled)
-    *   Enable A2DP sink (bluetooth.profile.a2dp.sink.enabled)
-    *   Disable the AVRCP controller (bluetooth.profile.avrcp.controller.enabled)
-    *   Enable the AVRCP target (bluetooth.profile.avrcp.target.enabled)
-    *   Enable the HFP service (bluetooth.profile.hfp.ag.enabled, bluetooth.profile.hfp.hf.enabled)
-
-```makefile
-# The Bluetooth profiles that Fast Pair provider simulator expect to have enabled.
-PRODUCT_PRODUCT_PROPERTIES += \
-    bluetooth.device.default_name=FastPairProviderSimulator \
-    bluetooth.profile.a2dp.source.enabled=false \
-    bluetooth.profile.a2dp.sink.enabled=true \
-    bluetooth.profile.avrcp.controller.enabled=false \
-    bluetooth.profile.avrcp.target.enabled=true \
-    bluetooth.profile.hfp.ag.enabled=true \
-    bluetooth.profile.hfp.hf.enabled=true
-```
-
-*   Adjust Bluetooth TX power limitation in Bluetooth module and disable the
-    Fast Pair in Google Play service (aka GMS)
-
-```shell
-adb root
-adb shell am broadcast \
-  -a 'com.google.android.gms.phenotype.FLAG_OVERRIDE' \
-  --es package "com.google.android.gms.nearby" \
-  --es user "\*" \
-  --esa flags "enabled" \
-  --esa types "boolean" \
-  --esa values "false" \
-  com.google.android.gms
-```
-
-### Running tests
-
-To run the tests, enter:
-
-```shell
-atest -v CtsNearbyMultiDevicesTestSuite
-```
-
-## Manual testing the seeker side with headsets
-
-Use this testing with headsets such as Google Pixel buds.
-
-The `FastPairTestDataProviderService.apk` is a run-time configurable Fast Pair
-data provider service (`FastPairDataProviderService`):
-
-`packages/modules/Connectivity/nearby/tests/multidevices/clients/test_service/fastpair_seeker_data_provider`
-
-It has a test data manager(`FastPairTestDataManager`) to receive intent
-broadcasts to add or clear the test data cache (`FastPairTestDataCache`). This
-cache provides the data to return to the Fast Pair module for onXXX calls (for
-example, `onLoadFastPairAntispoofKeyDeviceMetadata`) so you can feed the
-metadata for your device.
-
-Here are some sample uses:
-
-*   Send FastPairAntispoofKeyDeviceMetadata for PixelBuds-A to
-    FastPairTestDataCache \
-    `./fast_pair_data_provider_shell.sh -m=718c17
-    -a=../test_data/fastpair/pixelbuds-a_antispoofkey_devicemeta_json.txt`
-*   Send FastPairAccountDevicesMetadata for PixelBuds-A to FastPairTestDataCache
-    \
-    `./fast_pair_data_provider_shell.sh
-    -d=../test_data/fastpair/pixelbuds-a_account_devicemeta_json.txt`
-*   Send FastPairAntispoofKeyDeviceMetadata for Provider Simulator to
-    FastPairTestDataCache \
-    `./fast_pair_data_provider_shell.sh -m=00000c
-    -a=../test_data/fastpair/simulator_antispoofkey_devicemeta_json.txt`
-*   Send FastPairAccountDevicesMetadata for Provider Simulator to
-    FastPairTestDataCache \
-    `./fast_pair_data_provider_shell.sh
-    -d=../test_data/fastpair/simulator_account_devicemeta_json.txt`
-*   Clear FastPairTestDataCache \
-    `./fast_pair_data_provider_shell.sh -c`
-
-See
-[host/tool/fast_pair_data_provider_shell.sh](host/tool/fast_pair_data_provider_shell.sh)
-for more documentation.
-
-To install the data provider as system private app, consider remounting the
-system partition:
-
-```
-adb root && adb remount
-```
-
-Push it in:
-
-```
-adb push ${ANDROID_PRODUCT_OUT}/system/app/NearbyFastPairSeekerDataProvider
-/system/priv-app/
-```
-
-Then reboot:
-
-```
-adb reboot
-```
-
-## Manual testing the seeker side with provider simulator app
-
-The `NearbyFastPairProviderSimulatorApp.apk` is a simple Android app to let you
-control the state of the Fast Pair provider simulator. Install this app on phone
-2 (Fast Pair provider role) to work correctly.
-
-See
-[clients/test_support/fastpair_provider/simulator_app/Android.bp](clients/test_support/fastpair_provider/simulator_app/Android.bp)
-for more documentation.

-/**
- * Simulates a Fast Pair device (e.g. a headset).
- *
- * <p>Note: There are two deviations from the spec:
- *
- * <ul>
- *   <li>Instead of using the public address when in pairing mode (discoverable), it always uses the
- *       random private address (RPA), because that's how stock Android works. To work around this,
- *       it implements the BR/EDR Handover profile (which is no longer part of the Fast Pair spec)
- *       when simulating a keyless device (i.e. Fast Pair 1.0), which allows the phone to ask for
- *       the public address. When there is an anti-spoofing key, i.e. Fast Pair 2.0, the public
- *       address is delivered via the Key-based Pairing handshake. b/79374759 tracks fixing this.
- *   <li>The simulator always identifies its device capabilities as Keyboard/Display, even when
- *       simulating a keyless (Fast Pair 1.0) device that should identify as NoInput/NoOutput.
- *       b/79377125 tracks fixing this.

-# A script to interactively manage FastPairTestDataCache of FastPairTestDataProviderService.
-#
-# FastPairTestDataProviderService (../../clients/test_service/fastpair_seeker_data_provider/) is a
-# run-Time configurable FastPairDataProviderService. It has a FastPairTestDataManager to receive
-# Intent broadcast to add/clear the FastPairTestDataCache. This cache provides the data to return to
-# the Nearby Mainline module for onXXX calls (ex: onLoadFastPairAntispoofKeyDeviceMetadata).
-#
-# To use this tool, make sure you:
-# 1. Flash the ROM your built to the device
-# 2. Build and install NearbyFastPairSeekerDataProvider to the device
-# m NearbyFastPairSeekerDataProvider
-# adb install -r -g ${ANDROID_PRODUCT_OUT}/system/app/NearbyFastPairSeekerDataProvider/NearbyFastPairSeekerDataProvider.apk
-# 3. Check FastPairService can connect to the FastPairTestDataProviderService.
-# adb logcat ServiceMonitor:* *:S
-# (ex: ServiceMonitor: [FAST_PAIR_DATA_PROVIDER] connected to {
-# android.nearby.fastpair.seeker.dataprovider/android.nearby.fastpair.seeker.dataprovider.FastPairTestDataProviderService})
-#
-# Sample Usages:
-# 1. Send FastPairAntispoofKeyDeviceMetadata for PixelBuds-A to FastPairTestDataCache
-# ./fast_pair_data_provider_shell.sh -m=718c17  -a=../test_data/fastpair/pixelbuds-a_antispoofkey_devicemeta_json.txt
-# 2. Send FastPairAccountDevicesMetadata for PixelBuds-A to FastPairTestDataCache
-# ./fast_pair_data_provider_shell.sh -d=../test_data/fastpair/pixelbuds-a_account_devicemeta_json.txt

-# 4. Send FastPairAccountDevicesMetadata for Provider Simulator to FastPairTestDataCache
-# ./fast_pair_data_provider_shell.sh -d=../test_data/fastpair/simulator_account_devicemeta_json.txt
