+# 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
+# 3. Send FastPairAntispoofKeyDeviceMetadata for Provider Simulator to FastPairTestDataCache
+# ./fast_pair_data_provider_shell.sh -m=00000c -a=../test_data/fastpair/simulator_antispoofkey_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
+# 5. Clear FastPairTestDataCache
+# ./fast_pair_data_provider_shell.sh -c
+#
