+
+ "Source" form shall mean the preferred form for making modifications,
+ including but not limited to software source code, documentation
+ source, and configuration files.
+
+ "Object" form shall mean any form resulting from mechanical

+ and conversions to other media types.
+
+ "Work" shall mean the work of authorship, whether in Source or
+ Object form, made available under the License, as indicated by a
+ copyright notice that is included in or attached to the work
+ (an example is provided in the Appendix below).
+
+ "Derivative Works" shall mean any work, whether in Source or Object
+ form, that is based on (or derived from) the Work and for which the
+ editorial revisions, annotations, elaborations, or other modifications
+ represent, as a whole, an original work of authorship. For the purposes

+ separable from, or merely link (or bind by name) to the interfaces of,
+ the Work and Derivative Works thereof.
+
+ "Contribution" shall mean any work of authorship, including

+ means any form of electronic, verbal, or written communication sent
+ to the Licensor or its representatives, including but not limited to

+ worldwide, non-exclusive, no-charge, royalty-free, irrevocable
+ copyright license to reproduce, prepare Derivative Works of,
+ publicly display, publicly perform, sublicense, and distribute the

+ worldwide, non-exclusive, no-charge, royalty-free, irrevocable
+ (except as stated in this section) patent license to make, have made,
+ use, offer to sell, sell, import, and otherwise transfer the Work,
+ where such license applies only to those patent claims licensable
+ by such Contributor that are necessarily infringed by their
+ Contribution(s) alone or by combination of their Contribution(s)
+ with the Work to which such Contribution(s) was submitted. If You
+ institute patent litigation against any entity (including a
+ cross-claim or counterclaim in a lawsuit) alleging that the Work
+ or a Contribution incorporated within the Work constitutes direct
+ or contributory patent infringement, then any patent licenses
+ granted to You under this License for that Work shall terminate
+ as of the date such litigation is filed.
+
+ 4. Redistribution. You may reproduce and distribute copies of the
+ Work or Derivative Works thereof in any medium, with or without
+ modifications, and in Source or Object form, provided that You
+ meet the following conditions:
+
+ (a) You must give any other recipients of the Work or
+ Derivative Works a copy of this License; and
+
+ (b) You must cause any modified files to carry prominent notices
+ stating that You changed the files; and
+
+ (c) You must retain, in the Source form of any Derivative Works
+ that You distribute, all copyright, patent, trademark, and
+ attribution notices from the Source form of the Work,
+ excluding those notices that do not pertain to any part of
+ the Derivative Works; and
+
+ (d) If the Work includes a "NOTICE" text file as part of its
+ distribution, then any Derivative Works that You distribute must
+ include a readable copy of the attribution notices contained
+ within such NOTICE file, excluding those notices that do not
+ pertain to any part of the Derivative Works, in at least one
+ of the following places: within a NOTICE text file distributed
+ as part of the Derivative Works; within the Source form or
+ documentation, if provided along with the Derivative Works; or,
+ within a display generated by the Derivative Works, if and
+ wherever such third-party notices normally appear. The contents
+ of the NOTICE file are for informational purposes only and
+ do not modify the License. You may add Your own attribution
+ notices within Derivative Works that You distribute, alongside
+ or as an addendum to the NOTICE text from the Work, provided
+ that such additional attribution notices cannot be construed
+ as modifying the License.
+
+ You may add Your own copyright statement to Your modifications and
+ may provide additional or different license terms and conditions
+ for use, reproduction, or distribution of Your modifications, or
+ for any such Derivative Works as a whole, provided Your use,
+ reproduction, and distribution of the Work otherwise complies with
+ the conditions stated in this License.
+
+ 5. Submission of Contributions. Unless You explicitly state otherwise,
+ any Contribution intentionally submitted for inclusion in the Work
+ by You to the Licensor shall be under the terms and conditions of
+ this License, without any additional terms or conditions.
+ Notwithstanding the above, nothing herein shall supersede or modify
+ the terms of any separate license agreement you may have executed
+ with Licensor regarding such Contributions.
+

+ except as required for reasonable and customary use in describing the
+ origin of the Work and reproducing the content of the NOTICE file.
+
+ 7. Disclaimer of Warranty. Unless required by applicable law or
+ agreed to in writing, Licensor provides the Work (and each
+ Contributor provides its Contributions) on an "AS IS" BASIS,
+ WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or
+ implied, including, without limitation, any warranties or conditions
+ of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A
+ PARTICULAR PURPOSE. You are solely responsible for determining the

+ risks associated with Your exercise of permissions under this License.
+
+ 8. Limitation of Liability. In no event and under no legal theory,
+ whether in tort (including negligence), contract, or otherwise,
+ unless required by applicable law (such as deliberate and grossly
+ negligent acts) or agreed to in writing, shall any Contributor be
+ liable to You for damages, including any direct, indirect, special,
+ incidental, or consequential damages of any character arising as a
+ result of this License or out of the use or inability to use the
+ Work (including but not limited to damages for loss of goodwill,
+ work stoppage, computer failure or malfunction, or any and all
+ other commercial damages or losses), even if such Contributor
+ has been advised of the possibility of such damages.
+
+ 9. Accepting Warranty or Additional Liability. While redistributing
+ the Work or Derivative Works thereof, You may choose to offer,
+ and charge a fee for, acceptance of support, warranty, indemnity,
+ or other liability obligations and/or rights consistent with this
+ License. However, in accepting such obligations, You may act only
+ on Your own behalf and on Your sole responsibility, not on behalf
+ of any other Contributor, and only if You agree to indemnify,
+ defend, and hold each Contributor harmless for any liability
+ incurred by, or claims asserted against, such Contributor by reason
+ of your accepting any such warranty or additional liability.
+
+ END OF TERMS AND CONDITIONS

+ * asocket_accept()
+ * asocket_read()
+ * asocket_write()
+ * These calls are similar to the regular syscalls, but can be aborted with:

+ *
+ * Calling close() on a regular POSIX socket does not abort blocked syscalls on
+ * that socket in other threads.
+ *
+ * After calling asocket_abort() the socket cannot be reused.
+ *
+ * Call asocket_destory() *after* all threads have finished with the socket to
+ * finish closing the socket and free the asocket structure.
+ *
+ * The helper is implemented by setting the socket non-blocking to initiate
+ * syscalls connect(), accept(), read(), write(), then using a blocking poll()
+ * on both the primary socket and a local pipe. This makes the poll() abortable
+ * by writing a byte to the local pipe in asocket_abort().
+ *
+ * asocket_create() sets the fd to non-blocking mode. It must not be changed to
+ * blocking mode.
+ *
+ * Using asocket will triple the number of file descriptors required per
+ * socket, due to the local pipe. It may be possible to use a global pipe per
+ * process rather than per socket, but we have not been able to come up with a
+ * race-free implementation yet.

+ * A handful of basic atomic operations. The appropriate pthread
+ * functions should be used instead of these whenever possible.
+ *
+ * The "acquire" and "release" terms can be defined intuitively in terms
+ * of the placement of memory barriers in a simple lock implementation:
+ * - wait until compare-and-swap(lock-is-free --> lock-is-held) succeeds
+ * - barrier
+ * - [do work]
+ * - barrier
+ * - store(lock-is-free)
+ * In very crude terms, the initial (acquire) barrier prevents any of the
+ * "work" from happening before the lock is held, and the later (release)
+ * barrier ensures that all of the work happens before the lock is released.
+ * (Think of cached writes, cache read-ahead, and instruction reordering
+ * around the CAS and store instructions.)
+ *
+ * The barriers must apply to both the compiler and the CPU. Note it is
+ * legal for instructions that occur before an "acquire" barrier to be
+ * moved down below it, and for instructions that occur after a "release"
+ * barrier to be moved up above it.
+ *
+ * The ARM-driven implementation we use here is short on subtlety,
+ * and actually requests a full barrier from the compiler and the CPU.
+ * The only difference between acquire and release is in whether they
+ * are issued before or after the atomic operation with which they
+ * are associated. To ease the transition to C/C++ atomic intrinsics,
+ * you should not rely on this, and instead assume that only the minimal
+ * acquire/release protection is provided.
+ *
+ * NOTE: all int32_t* values are expected to be aligned on 32-bit boundaries.

+ * Definition of the axis
+ * ----------------------
+ *
+ * This API is relative to the screen of the device in its default orientation,
+ * that is, if the device can be used in portrait or landscape, this API
+ * is only relative to the NATURAL orientation of the screen. In other words,
+ * the axis are not swapped when the device's screen orientation changes.
+ * Higher level services /may/ perform this transformation.
+ *
+ * x<0 x>0
+ * ^
+ * |
+ * +-----------+--> y>0
+ * | |

+ * +----------/+ y<0
+ * /
+ * /
+ * |/ z>0 (toward the sky)
+ *
+ * O: Origin (x=0,y=0,z=0)
+ *
+ *
+ * Orientation
+ * -----------
+ *
+ * All values are angles in degrees.
+ *
+ * Orientation sensors return sensor events for all 3 axes at a constant
+ * rate defined by setDelay().
+ *
+ * azimuth: angle between the magnetic north direction and the Y axis, around
+ * the Z axis (0<=azimuth<360).
+ * 0=North, 90=East, 180=South, 270=West
+ *
+ * pitch: Rotation around X axis (-180<=pitch<=180), with positive values when
+ * the z-axis moves toward the y-axis.
+ *
+ * roll: Rotation around Y axis (-90<=roll<=90), with positive values when
+ * the x-axis moves towards the z-axis.
+ *
+ * Note: For historical reasons the roll angle is positive in the clockwise
+ * direction (mathematically speaking, it should be positive in the
+ * counter-clockwise direction):
+ *
+ * Z
+ * ^
+ * (+roll) .--> |
+ * / |
+ * | | roll: rotation around Y axis
+ * X <-------(.)
+ * Y
+ * note that +Y == -roll
+ *
+ *
+ *
+ * Note: This definition is different from yaw, pitch and roll used in aviation
+ * where the X axis is along the long side of the plane (tail to nose).
+ *
+ *
+ * Acceleration
+ * ------------
+ *
+ * All values are in SI units (m/s^2) and measure the acceleration of the
+ * device minus the force of gravity.
+ *
+ * Acceleration sensors return sensor events for all 3 axes at a constant
+ * rate defined by setDelay().
+ *
+ * x: Acceleration minus Gx on the x-axis
+ * y: Acceleration minus Gy on the y-axis
+ * z: Acceleration minus Gz on the z-axis
+ *
+ * Examples:
+ * When the device lies flat on a table and is pushed on its left side
+ * toward the right, the x acceleration value is positive.
+ *
+ * When the device lies flat on a table, the acceleration value is +9.81,
+ * which correspond to the acceleration of the device (0 m/s^2) minus the
+ * force of gravity (-9.81 m/s^2).
+ *
+ * When the device lies flat on a table and is pushed toward the sky, the
+ * acceleration value is greater than +9.81, which correspond to the
+ * acceleration of the device (+A m/s^2) minus the force of
+ * gravity (-9.81 m/s^2).
+ *
+ *
+ * Magnetic Field
+ * --------------
+ *
+ * All values are in micro-Tesla (uT) and measure the ambient magnetic
+ * field in the X, Y and Z axis.
+ *
+ * Magnetic Field sensors return sensor events for all 3 axes at a constant
+ * rate defined by setDelay().
+ *
+ * Gyroscope
+ * ---------
+ * All values are in radians/second and measure the rate of rotation
+ * around the X, Y and Z axis. The coordinate system is the same as is
+ * used for the acceleration sensor. Rotation is positive in the
+ * counter-clockwise direction (right-hand rule). That is, an observer
+ * looking from some positive location on the x, y or z axis at a device
+ * positioned on the origin would report positive rotation if the device
+ * appeared to be rotating counter clockwise. Note that this is the
+ * standard mathematical definition of positive rotation and does not agree
+ * with the definition of roll given earlier.
+ * The range should at least be 17.45 rad/s (ie: ~1000 deg/s).
+ *
+ * Proximity
+ * ---------
+ *
+ * The distance value is measured in centimeters. Note that some proximity
+ * sensors only support a binary "close" or "far" measurement. In this case,
+ * the sensor should report its maxRange value in the "far" state and a value
+ * less than maxRange in the "near" state.
+ *
+ * Proximity sensors report a value only when it changes and each time the
+ * sensor is enabled. setDelay() is ignored.
+ *
+ * Light
+ * -----
+ *
+ * The light sensor value is returned in SI lux units.
+ *
+ * Light sensors report a value only when it changes and each time the
+ * sensor is enabled. setDelay() is ignored.
+ *
+ * Pressure
+ * --------
+ *
+ * The pressure sensor value is returned in hectopascal (hPa)
+ *
+ * Pressure sensors report events at a constant rate defined by setDelay().
+ *
+ * Gravity
+ * -------
+ * A gravity output indicates the direction of and magnitude of gravity in the devices's
+ * coordinates. On Earth, the magnitude is 9.8. Units are m/s^2. The coordinate system
+ * is the same as is used for the acceleration sensor.
+ * When the device is at rest, the output of the gravity sensor should be identical
+ * to that of the accelerometer.
+ *
+ * Linear Acceleration
+ * -------------------
+ * Indicates the linear acceleration of the device in device coordinates, not including gravity.
+ * This output is essentially Acceleration - Gravity. Units are m/s^2. The coordinate system is
+ * the same as is used for the acceleration sensor.
+ * The output of the accelerometer, gravity and linear-acceleration sensors must obey the
+ * following relation:
+ *
+ * acceleration = gravity + linear-acceleration
+ *
+ *
+ * Rotation Vector
+ * ---------------
+ * A rotation vector represents the orientation of the device as a combination
+ * of an angle and an axis, in which the device has rotated through an angle
+ * theta around an axis <x, y, z>. The three elements of the rotation vector
+ * are <x*sin(theta/2), y*sin(theta/2), z*sin(theta/2)>, such that the magnitude
+ * of the rotation vector is equal to sin(theta/2), and the direction of the
+ * rotation vector is equal to the direction of the axis of rotation. The three
+ * elements of the rotation vector are equal to the last three components of a
+ * unit quaternion <cos(theta/2), x*sin(theta/2), y*sin(theta/2), z*sin(theta/2)>.
+ * Elements of the rotation vector are unitless. The x, y, and z axis are defined
+ * in the same was as for the acceleration sensor.
+ *
+ * The rotation-vector is stored as:
+ *
+ * sensors_event_t.data[0] = x*sin(theta/2)
+ * sensors_event_t.data[1] = y*sin(theta/2)
+ * sensors_event_t.data[2] = z*sin(theta/2)
+ * sensors_event_t.data[3] = cos(theta/2)

+
+// The AudioPolicyInterface and AudioPolicyClientInterface classes define the communication interfaces
+// between the platform specific audio policy manager and Android generic audio policy manager.
+// The platform specific audio policy manager must implement methods of the AudioPolicyInterface class.
+// This implementation makes use of the AudioPolicyClientInterface to control the activity and
+// configuration of audio input and output streams.
+//
+// The platform specific audio policy manager is in charge of the audio routing and volume control
+// policies for a given platform.
+// The main roles of this module are:
+// - keep track of current system state (removable device connections, phone state, user requests...).
+// System state changes and user actions are notified to audio policy manager with methods of the AudioPolicyInterface.
+// - process getOutput() queries received when AudioTrack objects are created: Those queries
+// return a handler on an output that has been selected, configured and opened by the audio policy manager and that
+// must be used by the AudioTrack when registering to the AudioFlinger with the createTrack() method.
+// When the AudioTrack object is released, a putOutput() query is received and the audio policy manager can decide
+// to close or reconfigure the output depending on other streams using this output and current system state.
+// - similarly process getInput() and putInput() queries received from AudioRecord objects and configure audio inputs.
+// - process volume control requests: the stream volume is converted from an index value (received from UI) to a float value
+// applicable to each output as a function of platform specific settings and current output route (destination device). It
+// also make sure that streams are not muted if not allowed (e.g. camera shutter sound in some countries).
+//
+// The platform specific audio policy manager is provided as a shared library by platform vendors (as for libaudio.so)
+// and is linked with libaudioflinger.so

+ * effect engine owner, the control will be transfered to the new application. Otherwise
+ * control will remain to the previous application. In this case, the new application will be
+ * notified of changes in effect engine state or control ownership by the effect callback.
+ * After creating the AudioEffect, the application must call the initCheck() method and

+// of the effect control API for a particular effect are located.
+// - 2 it is the address of the context of a particular effect instance.
+// A typical implementation in the effect library would define a structure as follows:
+// struct effect_module_s {
+// const struct effect_interface_s *itfe;
+// effect_config_t config;
+// effect_context_t context;
