## Camera Provider HAL ##
|
|
---
|
|
|
|
## Overview: ##
|
|
|
|
The camera.provider HAL is used by the Android camera service to discover,
|
|
query, and open individual camera devices.
|
|
|
|
It also allows for direct control of the flash unit of camera devices that have
|
|
one, for turning on/off torch mode.
|
