<a name="androidSensorsIntroduction"></a><h2>Introduction</h2>
|
|
|
|
<p>Android defines a user space C abstraction interface for sensor hardware. The interface header is defined in
|
|
<code>hardware/libhardware/include/hardware/sensors.h</code>.
|
|
In order to integrate sensors with Android you need to build a shared library that implements this interface.
|
|
|
|
The types of sensors currently supported by Android include:
|
|
<ul>
|
|
<li>Accelerometer</li>
|
|
<li>Magnetic Field</li>
|
|
<li>Orientation</li>
|
|
<li>Gyroscope</li>
|
|
<li>Light</li>
|
|
<li>Pressure</li>
|
|
<li>Temperature</li>
|
|
<li>Proximity</li>
|
|
</ul>
|
|
</p>

<a name="androidSensorBuildingDriver"></a><h2>Building a Sensor Library</h2>
|
|
<p> To implement a Sensors driver, create a shared library that implements the interface defined in <code>sensors.h</code>. You must name your shared library
|
|
<code>libsensors.so</code> so that it will get loaded from <code>/system/lib</code> at runtime.
|
|
