25157e458d6e10b027d1ba6b78b0487156c9f57a 16-Apr-2012 Jeff Brown <jeffbrown@google.com> Refactor SensorManager to move non-API bits into a subclass.

Changed the SensorManager class so that it only contains API-related
bits including what's needed to support legacy sensors. Mostly just
moved stuff around. Making the class abstract is safe because
it does not have a visible constructor in the API.

One minor change is that the cache of sensor type to sensor lists
is now per instance of SensorManager instead of being static.
We can fix this if desired.

Another small change is that we bail out early from registerListener
if the listener has already been registered for the particular
sensor. This happened for both legacy and standard listeners.
The problem is that the ListenerDelegate maintains two lists of
sensors, one is a Map and the other is a List. Adding a sensor
twice causes one entry to be added to the Map and two entries to be
added to the List, but when the sensor is removed the next time, only
one entry is removed from the List, leaving it in an inconsistent

Removed Sensor.getLegacyType() since the value it provides is only
needed in LegacyListener and we don't really save any significant
computation by caching it. Removing the field makes support for
legacy sensors a little more self-contained.

4fe6c3e51be77e35f40872cdbca6c80f8f8b7ecb 14-Sep-2010 Jeff Brown <jeffbrown@google.com> Replace epoll() with poll() and rename PollLoop to Looper.

As part of this change, consolidated and cleaned up the Looper API so
that there are fewer distinctions between the NDK and non-NDK declarations
(no need for two callback types, etc.).

Removed the dependence on specific constants from sys/poll.h such as
POLLIN. Instead looper.h defines events like LOOPER_EVENT_INPUT for
the events that it supports. That should help make any future
under-the-hood implementation changes easier.

Fixed a couple of compiler warnings along the way.

050b56244ff46d43e4886018d7cd20f0b1dc02b9 30-Jul-2010 Mathias Agopian <mathias@google.com> Added SensorManager.getMinDelay()

Exposed the new "min delay" sensor property through native and
java sensor apis. This allows the caller to know what is the
maximum rate at which a sensor can return events, or, if a sensor
works in "update" mode (events returned only when the value changes).

Also augmented SensorManager.regusterSensorEvent() so that it can
accept a value in microsecond in addition to the 4 constants already

1bf797857e025e8a71db86fb9e79765a767ec1eb 15-Jul-2010 Mathias Agopian <mathias@google.com> new SensorService

remove old sensor service and implement SensorManager
on top of the new (native) SensorManger API.

270e87f71abc2edf446dbec20c725c823e8c7f37 22-May-2009 Mike Lockwood <lockwood@android.com> Sensors: Use a native_handle for the data channel instead of a single file descriptor.

This eliminates the requirement that all sensors share a single file descriptor.
This, along with concurrent changes in other projects, fixes bugs b/1614524 and b/1614481
