+ * A channel mask per se only defines the presence or absence of a channel, not
+ * the order.  See AUDIO_INTERLEAVE_* for the platform convention of order.
+ *
+ * AudioChannelMask is an opaque type and its internal layout should not be
+ * assumed as it may change in the future.  Instead, always use functions
+ * to examine it.
+ *
+ * These are the current representations:
+ *
+ *   REPRESENTATION_POSITION
+ *     is a channel mask representation for position assignment.  Each low-order
+ *     bit corresponds to the spatial position of a transducer (output), or
+ *     interpretation of channel (input).  The user of a channel mask needs to
+ *     know the context of whether it is for output or input.  The constants
+ *     OUT_* or IN_* apply to the bits portion.  It is not permitted for no bits
+ *     to be set.
+ *
+ *   REPRESENTATION_INDEX
+ *     is a channel mask representation for index assignment.  Each low-order
+ *     bit corresponds to a selected channel.  There is no platform
+ *     interpretation of the various bits.  There is no concept of output or
+ *     input.  It is not permitted for no bits to be set.
+ *
+ * All other representations are reserved for future use.
+ *
+ * Warning: current representation distinguishes between input and output, but
+ * this will not the be case in future revisions of the platform. Wherever there
+ * is an ambiguity between input and output that is currently resolved by
+ * checking the channel mask, the implementer should look for ways to fix it
+ * with additional information outside of the mask.

+ * 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|

+ *                            """"""""""
+ * 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.

+ * Other dataspaces include depth measurement data from a depth camera.
+ *
+ * A dataspace is comprised of a number of fields.

+ * Color modes that may be supported by a display.
+ *
+ * Definitions:
+ * Rendering intent generally defines the goal in mapping a source (input)
+ * 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.

+ * a process, but not mapped in to that process's address space.
+ * A secondary goal is to be able to categorize memory used by a process into
+ * GL, graphics, etc. All memory sizes must be in real memory usage,
+ * accounting for stride, bit depth, rounding up to page size, etc.
+ *
+ * Constructor for the interface should be used to perform memtrack management
+ * setup actions and is called once before any calls to getMemory().
+ */

+     * getMemory() populates MemtrackRecord vector with the sizes of memory

+     *
+     * This function must be thread-safe, it may get called from multiple
+     * threads at the same time.
+     *
+     * A process collecting memory statistics will call getMemory for each
+     * combination of pid and memory type. For each memory type that it
+     * recognizes, the HAL must fill out an array of memtrack_record
+     * structures breaking down the statistics of that memory type as much as
+     * possible. For example,
+     * getMemory(<pid>, GL) might return:
+     * { { 4096,  ACCOUNTED | PRIVATE | SYSTEM },
+     *   { 40960, UNACCOUNTED | PRIVATE | SYSTEM },
+     *   { 8192,  ACCOUNTED | PRIVATE | DEDICATED },
+     *   { 8192,  UNACCOUNTED | PRIVATE | DEDICATED } }
+     * If the HAL cannot differentiate between SYSTEM and DEDICATED memory, it
+     * could return:
+     * { { 12288,  ACCOUNTED | PRIVATE },
+     *   { 49152,  UNACCOUNTED | PRIVATE } }
+     *
+     * Memory must not overlap between types. For example, a graphics buffer
+     * that has been mapped into the GPU as a surface must show up when
+     * GRAPHICS is requested and not when GL
+     * is requested.
+     *
+     * @param pid process for which memory information is requested
+     * @param type memory type that information is being requested about
+     * @return records vector of MemtrackRecord containing memory information

+ * 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)
+ * and the other can be a regular non wake_up sensor. Both of these sensors
