+ * GNSS Geofence.

+ * set as 30 secs is shown below. (confidence level and Unknown time limit are
+ * explained latter).

+ * | Unknown (30 secs) |
+ * """"""""""""""""""""""""""""

+ * | v v |

+ * | Inside | -----------> | Outside |
+ * | | <----------- | |
+ * """""""" ENTERED """""""""
+ *
+ * Inside state: We are 95% confident that the user is inside the geofence.
+ * Outside state: We are 95% confident that the user is outside the geofence
+ * Unknown state: Rest of the time.
+ *
+ * The Unknown state is better explained with an example:
+ *
+ * __________
+ * | c|
+ * | ___ | _______
+ * | |a| | | b |
+ * | """ | """""""
+ * | |
+ * """"""""""
+ * In the diagram above, "a" and "b" are 2 geofences and "c" is the accuracy
+ * circle reported by the GNSS subsystem. Now with regard to "b", the system is
+ * confident that the user is outside. But with regard to "a" is not confident
+ * whether it is inside or outside the geofence. If the accuracy remains the
+ * same for a sufficient period of time, the UNCERTAIN transition must be
+ * triggered with the state set to Unknown. If the accuracy improves later, an
+ * appropriate transition must be triggered. This "sufficient period of time"
+ * is defined by the parameter in the addGeofenceArea API.
+ * In other words, Unknown state can be interpreted as a state in which the
+ * GNSS subsystem isn't confident enough that the user is either inside or
+ * outside the Geofence. It moves to Unknown state only after the expiry of the
+ * timeout.
+ *
+ * The geofence callback needs to be triggered for the ENTERED and EXITED
+ * transitions, when the GNSS system is confident that the user has entered
+ * (Inside state) or exited (Outside state) the Geofence. An implementation
+ * which uses a value of 95% as the confidence is recommended. The callback
+ * must be triggered only for the transitions requested by the
+ * addGeofenceArea method.
+ *
+ * Even though the diagram and explanation talks about states and transitions,
+ * the callee is only interested in the transistions. The states are mentioned
+ * here for illustrative purposes.
+ *
+ * Startup Scenario: When the device boots up, if an application adds geofences,
+ * and then we get an accurate GNSS location fix, it needs to trigger the
+ * appropriate (ENTERED or EXITED) transition for every Geofence it knows about.
+ * By default, all the Geofences will be in the Unknown state.
+ *
+ * When the GNSS system is unavailable, gnssGeofenceStatusCb must be
+ * called to inform the upper layers of the same. Similarly, when it becomes
+ * available the callback must be called. This is a global state while the
+ * UNKNOWN transition described above is per geofence.
+ *
+ * An important aspect to note is that users of this API (framework), will use
+ * other subsystems like wifi, sensors, cell to handle Unknown case and
+ * hopefully provide a definitive state transition to the third party
+ * application. GNSS Geofence will just be a signal indicating what the GNSS
+ * subsystem knows about the Geofence.

+ * Color modes that may be supported by a display.
+ *
+ * Definitions:

+ * color to a destination device color for a given color mode.
+ *
+ * It is important to keep in mind three cases where mapping may be applied:
+ * 1. The source gamut is much smaller than the destination (display) gamut
+ * 2. The source gamut is much larger than the destination gamut (this will
+ * ordinarily be handled using colorimetric rendering, below)
+ * 3. The source and destination gamuts are roughly equal, although not
+ * completely overlapping
+ * Also, a common requirement for mappings is that skin tones should be
+ * preserved, or at least remain natural in appearance.
+ *
+ * Colorimetric Rendering Intent (All cases):
+ * Colorimetric indicates that colors should be preserved. In the case
+ * that the source gamut lies wholly within the destination gamut or is
+ * about the same (#1, #3), this will simply mean that no manipulations
+ * (no saturation boost, for example) are applied. In the case where some
+ * source colors lie outside the destination gamut (#2, #3), those will
+ * need to be mapped to colors that are within the destination gamut,
+ * while the already in-gamut colors remain unchanged.
+ *
+ * Non-colorimetric transforms can take many forms. There are no hard
+ * rules and it's left to the implementation to define.
+ * Two common intents are described below.
+ *
+ * Stretched-Gamut Enhancement Intent (Source < Destination):
+ * When the destination gamut is much larger than the source gamut (#1), the
+ * source primaries may be redefined to reflect the full extent of the
+ * destination space, or to reflect an intermediate gamut.
+ * Skin-tone preservation would likely be applied. An example might be sRGB
+ * input displayed on a DCI-P3 capable device, with skin-tone preservation.
+ *
+ * Within-Gamut Enhancement Intent (Source >= Destination):
+ * When the device (destination) gamut is not larger than the source gamut
+ * (#2 or #3), but the appearance of a larger gamut is desired, techniques
+ * such as saturation boost may be applied to the source colors. Skin-tone
+ * preservation may be applied. There is no unique method for within-gamut
+ * enhancement; it would be defined within a flexible color mode.

+ * pattern occupying unique byte addresses and with consistent byte offsets
+ * between neighboring pixels.
+ *
+ * The FlexLayout structure is used with any pixel format that can be
+ * represented by it, such as:
+ *
+ * - PixelFormat::YCbCr_*_888
+ * - PixelFormat::FLEX_RGB*_888
+ * - PixelFormat::RGB[AX]_888[8],BGRA_8888,RGB_888
+ * - PixelFormat::YV12,Y8,Y16,YCbCr_422_SP/I,YCrCb_420_SP
+ * - even implementation defined formats that can be represented by the
+ * structures
+ *
+ * Vertical increment (aka. row increment or stride) describes the distance in
+ * bytes from the first pixel of one row to the first pixel of the next row
+ * (below) for the component plane. This can be negative.
+ *
+ * Horizontal increment (aka. column or pixel increment) describes the
+ * distance in bytes from one pixel to the next pixel (to the right) on the
+ * same row for the component plane. This can be negative.
+ *
+ * Each plane can be subsampled either vertically or horizontally by a
+ * power-of-two factor.
+ *
+ * The bit-depth of each component can be arbitrary, as long as the pixels are
+ * laid out on whole bytes, in native byte-order, using the most significant
+ * bits of each unit.

+ * structures breaking down the statistics of that memory type as much as

+ * could return:
+ * { { 12288, ACCOUNTED | PRIVATE },
+ * { 49152, UNACCOUNTED | PRIVATE } }
+ *
+ * Memory must not overlap between types. For example, a graphics buffer

+ * GRAPHICS is requested and not when GL
+ * is requested.
+ *
+ * @param pid process for which memory information is requested

+ * 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)
