+ * Sensor type
+ *
+ * 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
+ *
+ * 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.
+ *
+ * Each sensor also has a "typeAsString".
+ * - 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.

+ * Wake up sensors.
+ * Each sensor may have either or both a wake-up and a non-wake variant.
+ * When registered in batch mode, wake-up sensors will wake up the AP when
+ * their FIFOs are full or when the batch timeout expires. A separate FIFO has
+ * to be maintained for wake up sensors and non wake up sensors. The non
+ * wake-up sensors need to overwrite their FIFOs when they are full till the AP
+ * wakes up and the wake-up sensors will wake-up the AP when their FIFOs are
+ * full or when the batch timeout expires without losing events.
+ * Wake-up and non wake-up variants of each sensor can be activated at
+ * different rates independently of each other.
+ *
+ * Note: Proximity sensor and significant motion sensor which were defined in
+ * previous releases are also wake-up sensors and should be treated as such.
+ * Wake-up one-shot sensors like SIGNIFICANT_MOTION cannot be batched, hence
+ * the text about batch above doesn't apply to them. See the definitions of
+ * SENSOR_TYPE_PROXIMITY and SENSOR_TYPE_SIGNIFICANT_MOTION for more info.
+ *
+ * Set SENSOR_FLAG_WAKE_UP flag for all wake-up sensors.
+ *
+ * For example, A device can have two sensors both of SENSOR_TYPE_ACCELEROMETER
+ * and one of them can be a wake_up sensor (with SENSOR_FLAG_WAKE_UP flag set)
