Hi, I’m struggling to find examples or methods for me to make colour sliders for a UVC camera in android.  
If anyone can point me in the right direction if you had any example code, much would be appreciated!

I want to be able to adjust these settings:

- White Balance Temperature and Tint
- Saturation
- Contrast

before thinking about GUI …

- please show, how you access the camera (code)
- are you able to read/write those values at all ?
- opencv version, installed how, etc… ?

last, no you cannot use [opencv’s gui](https://docs.opencv.org/master/javadoc/org/opencv/highgui/HighGui.html)  
(it’s only for desktop, and does not come with sliders)
