From cb5d1077345d8f8b58ece5734454991a1ce75bf7 Mon Sep 17 00:00:00 2001 From: Steven Moreland Date: Sun, 10 Nov 2019 17:44:56 -0800 Subject: [PATCH] Restore vibrator@1.3 example service. To ensure we still have a HIDL vibrator service around for testing. This is from running command: git checkout 714220ef75707d826371c6c020c45663d6965f0c^ -- \ vibrator/1.3/example Bug: 141828236 Test: N/A Change-Id: Iffd5c8d4b95466f1b7b277c9f69d9a6001f12db8 --- vibrator/1.3/example/Android.bp | 33 +++ vibrator/1.3/example/OWNERS | 2 + vibrator/1.3/example/Vibrator.cpp | 277 ++++++++++++++++++ vibrator/1.3/example/Vibrator.h | 82 ++++++ ...d.hardware.vibrator@1.3-service.example.rc | 4 + ....hardware.vibrator@1.3-service.example.xml | 11 + vibrator/1.3/example/service.cpp | 46 +++ 7 files changed, 455 insertions(+) create mode 100644 vibrator/1.3/example/Android.bp create mode 100644 vibrator/1.3/example/OWNERS create mode 100644 vibrator/1.3/example/Vibrator.cpp create mode 100644 vibrator/1.3/example/Vibrator.h create mode 100644 vibrator/1.3/example/android.hardware.vibrator@1.3-service.example.rc create mode 100644 vibrator/1.3/example/android.hardware.vibrator@1.3-service.example.xml create mode 100644 vibrator/1.3/example/service.cpp diff --git a/vibrator/1.3/example/Android.bp b/vibrator/1.3/example/Android.bp new file mode 100644 index 0000000000..07f1c26db3 --- /dev/null +++ b/vibrator/1.3/example/Android.bp @@ -0,0 +1,33 @@ +// +// Copyright (C) 2019 The Android Open Source Project +// +// Licensed under the Apache License, Version 2.0 (the "License");
