recovery uses IHealth::getService
recovery is_battery_ok function uses get_health_service(),
which calls IHealth::getService("default") then
IHealth::getService("backup").
- An OEM can provide the default instance by installing
android.hardware.health@2.0-impl-<device>.so to recovery
partition.
- If that's not found, the "backup" instance is provided
to the recovery partition by default.
Test: call is_battery_ok() in recovery, successfully
get battery information.
