| 3 | <p>Android defines a user space C abstraction interface for LED hardware. The interface header is defined in |
| 4 | <code>hardware/libhardware/include/hardware/lights.h</code>. |
| 5 | In order to integrate LEDs with Android you need to build a shared library that implements this interface. |
| 6 | |
| 7 | The types of logical lights currently supported by Android include: |
| 8 | <ul> |
| 9 | <li>Backlight</li> |
| 10 | <li>Keyboard</li> |
| 11 | <li>Buttons</li> |
| 12 | <li>Battery</li> |
| 13 | <li>Notifications</li> |
| 14 | <li>Attention</li> |
| 15 | </ul> |

| 18 | <a name="androidLightsBuildingDriver"></a><h3>Building a Lights Library</h3> |
| 19 | <p> To implement a Lights driver, create a shared library that implements the interface defined in <code>lights.h</code>. You must name your shared library |
| 20 | <code>liblights.so</code> so that it will get loaded from <code>/system/lib</code> at runtime. |
