- * Sensor type
+ * Sensor string types for Android defined sensor types.
  *
- * Each sensor has a type which defines what this sensor measures and how
- * measures are reported. See the Base sensors and Composite sensors lists
- * for complete descriptions:
- * http://source.android.com/devices/sensors/base_triggers.html
- * http://source.android.com/devices/sensors/composite_sensors.html
+ * For Android defined sensor types, string type will be override in sensor service and thus no
+ * longer needed to be added to sensor_t data structure.
  *
- * Device manufacturers (OEMs) can define their own sensor types, for
- * their private use by applications or services provided by them. Such
- * sensor types are specific to an OEM and can't be exposed in the SDK.
- * These types must start at SENSOR_TYPE_DEVICE_PRIVATE_BASE.
- *
- * All sensors defined outside of the device private range must correspond to
- * a type defined in this file, and must satisfy the characteristics listed in
- * the description of the sensor type.
- *
- * Starting with version SENSORS_DEVICE_API_VERSION_1_2, each sensor also
- * has a stringType.
- *  - StringType of sensors inside of the device private range MUST be prefixed
- *    by the sensor provider's or OEM reverse domain name. In particular, they
- *    cannot use the "android.sensor" prefix.
- *  - StringType of sensors outside of the device private range MUST correspond
- *    to the one defined in this file (starting with "android.sensor").
- *    For example, accelerometers must have
- *      type=SENSOR_TYPE_ACCELEROMETER and
- *      stringType=SENSOR_STRING_TYPE_ACCELEROMETER
- *
- * When android introduces a new sensor type that can replace an OEM-defined
- * sensor type, the OEM must use the official sensor type and stringType on
- * versions of the HAL that support this new official sensor type.
- *
- * Example (made up): Suppose Google's Glass team wants to surface a sensor
- * detecting that Glass is on a head.
- *  - Such a sensor is not officially supported in android KitKat
- *  - Glass devices launching on KitKat can implement a sensor with
- *    type = 0x10001 and stringType = "com.google.glass.onheaddetector"
- *  - In L android release, if android decides to define
- *    SENSOR_TYPE_ON_HEAD_DETECTOR and STRING_SENSOR_TYPE_ON_HEAD_DETECTOR,
- *    those types should replace the Glass-team-specific types in all future
- *    launches.
- *  - When launching Glass on the L release, Google should now use the official
- *    type (SENSOR_TYPE_ON_HEAD_DETECTOR) and stringType.
- *  - This way, all applications can now use this sensor.
+ * These definitions are going to be removed soon.

 $ mmm hardware/libhardware
 
 This will generate the following binaries that we care about:
-i) out/target/product/XXX/system/lib/hw/vehicle.default.so
+i) out/target/product/XXX/vendor/lib/hw/vehicle.default.so
 ii) out/target/product/XXX/data/nativetest/vehicle_tests
 iii) out/target/product/XXX/system/bin/vehicle-hal-tool
 
 The location for the first shared library would be:
-$ adb push out/target/product/XXX/system/lib/hw/vehicle.default.so
-/system/lib/hw
+$ adb push out/target/product/XXX/vendor/lib/hw/vehicle.default.so
+/vendor/lib/hw
 You can also use 'adb sync' if you like, although this is the easiest least
 hassle way of putting it in place.
