- * 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.

- * supports dynamic sensor feature. Operations, such as batch, activate and setDelay, to this
- * special purpose sensor should be treated as no-op and return successful.
- *
- * A dynamic sensor connection indicates connection of a physical device or instantiation of a

- * opposite. A sensor event of SENSOR_TYPE_DYNAMIC_SENSOR_META type should be delivered regardless
- * of the activation status of the sensor in the event of dynamic sensor connection and
- * disconnection. In the sensor event, besides the common data entries, "dynamic_sensor_meta", which

- * structure and a uuid field, should be populated.
- *
- * At a dynamic sensor connection event, fields of sensor_t structure referenced by a pointer in

- * recovery of memory if the corresponding data is dynamicially allocated. However, the the pointer
- * must be valid until the first activate call to the sensor reported in this connection event. At a
- * dynamic sensor disconnection, the sensor_t pointer should be NULL.
- *
- * The sensor handle assigned to dynamic sensors should never be the same as that of any regular
- * static sensors, and should be unique until next boot. In another word, if a handle h is used for
- * a dynamic sensor A, that same number cannot be used for the same dynamic sensor A or another
- * dynamic sensor B even after disconnection of A until reboot.
- *
- * The UUID field will be used for identifying the sensor in addition to name, vendor and version
- * and type. For physical sensors of the same model, all sensors will have the same values in
- * sensor_t, but the UUID should be unique and persistent for each individual unit. An all zero UUID

- * noise level metrics, device internal temperature, etc.
- *
- * This type will never bind to a sensor. In other words, no sensor in the sensor list should be of
- * the type SENSOR_TYPE_ADDITIONAL_INFO. If a sensor HAL supports sensor additional information
- * feature, it reports sensor_event_t with "sensor" field set to handle of the reporting sensor and
- * "type" field set to SENSOR_TYPE_ADDITIONAL_INFO. Delivery of additional information events is
- * triggered under two conditions: an enable activate() call or a flush() call to the corresponding
- * sensor.
- *
- * A single additional information report consists of multiple frames. Sequences of these frames are
- * ordered using timestamps, which means the timestamps of sequential frames have to be at least 1
- * nanosecond apart from each other. Each frame is a sensor_event_t delivered through the HAL
- * interface, with related data stored in the "additional_info" field, which is of type
- * additional_info_event_t.  The "type" field of additional_info_event_t denotes the nature of the
- * payload data (see additional_info_type_t).  The "serial" field is used to keep the sequence of
- * payload data that spans multiple frames. The first frame of the entire report is always of type
- * AINFO_BEGIN, and the last frame is always AINFO_END.
- *
- * All additional information frames have to be delivered after flush complete event if flush() was

+* Enabling each external routing option is done by enabling each bit flag for the routing.
+* This property can support up to 128 external routings.
+* To give full flexibility, there is no standard definition for each bit flag and
+* assigning each big flag to specific routing type is decided by config_string.
+* config_string has format of each entry separated by ','
+* and each entry has format of bitFlagPositon:typeString[:physicalStreamNumber].

+*  physicalStreamNumber: This part is optional and represents physical stream to android
+*    which will be disabled when this routing is enabled. If not specified, this routing
+*    should not affect physical streams to android.
+* As an example, let's assume a system with two physical streams, 0 for media and 1 for
+* nav guidance. And let's assume external routing option of am fm radio, external navigation
+* guidance, satellite radio, and one custom. Let's assume that radio and satellite replaces
