-# Implement the 2.1 HAL instead!
+# Deprecated.
-It is strongly recommended that you implement the 2.1 HAL directly. See
-`hardware/interfaces/health/2.1/README.md` for more details.
+Health HIDL HAL 2.0 is deprecated and subject to removal. Please
+implement the Health AIDL HAL instead.
-# Upgrading from Health 1.0 HAL
-
-1. Remove `android.hardware.health@1.0*` from `PRODUCT_PACKAGES`
- in `device/<manufacturer>/<device>/device.mk`
-
-1. If the device does not have a vendor-specific `libhealthd` AND does not
- implement storage-related APIs, just do the following:
-
- ```mk
- PRODUCT_PACKAGES += android.hardware.health@2.0-service
- ```
-
- Otherwise, continue to the next step.
-
-1. Create directory
- `device/<manufacturer>/<device>/health`
-
-1. Create `device/<manufacturer>/<device>/health/Android.bp`
- (or equivalent `device/<manufacturer>/<device>/health/Android.mk`)
-
- ```bp
- cc_binary {
- name: "android.hardware.health@2.0-service.<device>",
- init_rc: ["android.hardware.health@2.0-service.<device>.rc"],
- proprietary: true,
- relative_install_path: "hw",
- srcs: [
- "HealthService.cpp",
- ],
-
- cflags: [
- "-Wall",
- "-Werror",
- ],
-
- static_libs: [
- "android.hardware.health@2.0-impl",
- "android.hardware.health@1.0-convert",
- "libhealthservice",
- "libbatterymonitor",
- ],
-
- shared_libs: [
- "libbase",
- "libcutils",
- "libhidlbase",
- "libutils",
- "android.hardware.health@2.0",
- ],
-
- header_libs: ["libhealthd_headers"],
-
- overrides: [
- "healthd",
- ],
- }
- ```
-
- 1. (recommended) To remove `healthd` from the build, keep "overrides" section.
- 1. To keep `healthd` in the build, remove "overrides" section.
-
-1. Create `device/<manufacturer>/<device>/health/android.hardware.health@2.0-service.<device>.rc`
-
- ```rc
- service vendor.health-hal-2-0 /vendor/bin/hw/android.hardware.health@2.0-service.<device>
- class hal
- user system
- group system
- capabilities WAKE_ALARM
- file /dev/kmsg w
- ```
-
-1. Create `device/<manufacturer>/<device>/health/HealthService.cpp`:
-
- ```c++
- #include <health2/service.h>
- int main() { return health_service_main(); }
- ```
-
-1. `libhealthd` dependency:
-
- 1. If the device has a vendor-specific `libhealthd.<soc>`, add it to static_libs.
-
- 1. If the device does not have a vendor-specific `libhealthd`, add the following
- lines to `HealthService.cpp`:
-
- ```c++
- #include <healthd/healthd.h>
- void healthd_board_init(struct healthd_config*) {}
-
- int healthd_board_battery_update(struct android::BatteryProperties*) {
- // return 0 to log periodic polled battery status to kernel log
- return 0;
- }
- ```
-
-1. Storage related APIs:
-
- 1. If the device does not implement `IHealth.getDiskStats` and
- `IHealth.getStorageInfo`, add `libhealthstoragedefault` to `static_libs`.
-
- 1. If the device implements one of these two APIs, add and implement the
- following functions in `HealthService.cpp`:
-
- ```c++
- void get_storage_info(std::vector<struct StorageInfo>& info) {
- // ...
- }
- void get_disk_stats(std::vector<struct DiskStats>& stats) {
- // ...
- }
- ```
-
-1. Update necessary SELinux permissions. For example,
-
- ```
- # device/<manufacturer>/<device>/sepolicy/vendor/file_contexts
- /vendor/bin/hw/android\.hardware\.health@2\.0-service\.<device> u:object_r:hal_health_default_exec:s0
-
- # device/<manufacturer>/<device>/sepolicy/vendor/hal_health_default.te
- # Add device specific permissions to hal_health_default domain, especially
- # if a device-specific libhealthd is used and/or device-specific storage related
- # APIs are implemented.
- ```
-
-1. Implementing health HAL in recovery. The health HAL is used for battery
-status checks during OTA for non-A/B devices. If the health HAL is not
-implemented in recovery, `is_battery_ok()` will always return `true`.
-
- 1. If the device does not have a vendor-specific `libhealthd`, nothing needs to
- be done. A "backup" implementation is provided in
- `android.hardware.health@2.0-impl-default`, which is always installed to recovery
- image by default.
-
- 1. If the device does have a vendor-specific `libhealthd`, implement the following
- module and include it in `PRODUCT_PACKAGES` (replace `<device>` with appropriate
- strings):
-
- ```bp
- // Android.bp
- cc_library_shared {
- name: "android.hardware.health@2.0-impl-<device>",
- recovery_available: true,
- relative_install_path: "hw",
- static_libs: [
- "android.hardware.health@2.0-impl",
- "libhealthd.<device>"
- // Include the following or implement device-specific storage APIs
- "libhealthstoragedefault",
- ],
- srcs: [
- "HealthImpl.cpp",
- ],
- overrides: [
- "android.hardware.health@2.0-impl-default",
- ],
- }
- ```
-
- ```c++
- // HealthImpl.cpp
- #include <health2/Health.h>
- #include <healthd/healthd.h>
- using android::hardware::health::V2_0::IHealth;
- using android::hardware::health::V2_0::implementation::Health;
- extern "C" IHealth* HIDL_FETCH_IHealth(const char* name) {
- const static std::string providedInstance{"default"};
- if (providedInstance != name) return nullptr;
- return Health::initInstance(&gHealthdConfig).get();
- }
- ```
-
- ```mk
- # device.mk
- PRODUCT_PACKAGES += android.hardware.health@2.0-impl-<device>
- ```

+details.
